FIELD

[0002] The present disclosure relates to a pod for use with a drone system equipped therewith.

BACKGROUND

[0003] In recent years, drones have been used in a variety of industries, and there are investigations into the use of drones as means for transporting cargo in the delivery industry that delivers cargo.

[0004] On one prior example, Japanese Unexamined Patent Application Publication 2018-203226, a flying vehicle is disclosed that transports cargo suspended from an arm in a drone. The flying vehicle is able to transport only a single package, so is ill suited to transport large quantities. Moreover, while the provision of a cargo space within the body of the drone, to transport a plurality of packages within this cargo space, may also be considered. However, the drone of this disclosure would be unavailable for use during the loading operations, which would reduce the operating efficiency of the drone

[0005] The solution of this disclosure resolves these and other problems of the art.

[0196] As discussed herein,“operator” can include a pilot or one or more individuals who may be in connection with a drone or system of drones.

[0197] The present disclosure is related to systems and methods thereof with respect to one or more pods of a drone system. In particular, this application discloses a pod configured to be removably loaded to a drone, whereby the pod can include a cargo space formed in the interior of the pod, to enable transporting of a plurality of packages while maintaining good operating efficiency of the drone.

[0198] In some examples, the pod is configured to store and transport cargo and includes a pod case with a long thin shape or a flat shape, formed with a cargo chamber, for storing cargo, therein; and a supporting mechanism for supporting the pod case in a state wherein an axis of the pod case is inclined in respect to the surface of the ground, when the pod is placed on the ground.

[0199] The pod of this disclosure can be configured to include a payload of approximately about 20 pounds, 70 pounds, 100 pounds, and up to approximately about 150 pounds. However, different payloads, both larger and smaller, are contemplated for use with the solution of this disclosure. The pod and corresponding aircraft can be configured for a cruising speed of approximately about 120 mph with a flight range of approximately about 20 to 40 km. However, different cruising speeds and/or flight ranges, both faster or slower and/or longer or shorter, are contemplated for use with the solution of this disclosure.

[0200] In some examples, structure of the pod can include a plurality of structural side spars joined by cross members. The spars and cross members can provide mounting and reaction surfaces for other components (e.g., doors, axles, covers, handles, actuators, hinges, gaskets, motors, controllers, batteries, etc.) All parts of the structure of the pod not covered by doors or cover panels can be fitted with a cover that is aerodynamically designed (e.g., in the shape of an airfoil). Cover features of the pod can be made of glass fiber, carbon fiber, or thin gauge aluminum sheet.

[0201] In some examples, side covers outboard of the spars of the pod can have a radius configured so that they blend into the upper and lower panels. Side covers can also be configured to seal and / or shield any exposed parts of the lift mechanism, while permitting a full range of operation of a lift mechanism of the pod, as shown and described more particularly below.

[0202] Fig. 1 and Fig. 2 depict an example of a UAV or drone that is used for transporting a pod in a pod transporting system according to an example. Fig. 1 is a front view, in the orientation for takeoff and landing and a top view in the orientation for level flight. When Fig. 1 is a front view of a drone 1, during takeoff or landing, the vertical direction is indicated by the X axis, and the crosswise direction or horizontal direction is indicated by the Y axis. It is understood that the drone 1 depicted can be any aircraft, including a fixed wing aircraft, a tail sitting aircraft, a helicopter, etc. For simplicity When Fig. 1 is viewed as the top view in the level flight orientation, the front/rear direction is indicated by the X axis, and the crosswise direction is indicated by the Y axis. Fig. 2 is a side view, in the takeoff/landing orientation, and a side view in the level flight orientation. When Fig. 2 is a side view in the takeoff/landing orientation, the vertical direction is indicated by the X axis. When Fig. 2 is the side view of the drone 1 in the level flight orientation, the front/rear direction or the horizontal direction is indicated by the X axis, and the vertical direction is indicated by the Z axis. In the drone 1 according to the present example, upward in the X axial direction in Fig. 1 and Fig. 2 is the nose portion or the nose side, or referred to as "forward," and downward is the tail portion or tail side, or referred to as “aft” or ’’rearward.” [0203] The drone 1 is a so-called tail sitter-type drone. That is, the drone 1 is configured to take off and land in the X axial direction (e.g., the vertical direction) so that the tail portion contacts the landing surface. Moreover, with the drone 1 oriented so that the X-Y plane is horizontal and the Z axial direction is perpendicular, drone 1 cruises horizontally in a state wherein the nose portion is positioned to the front in the horizontal direction, and tail portion is positioned to the rear in the horizontal direction.

[0204] The drone 1 depicted in Fig. 1 and Fig. 2 can include a pair of horizontal wings 2 that are equipped extending in the X-Y plane in Fig. 1, arranged in parallel, with a prescribed distance therebetween in the vertical direction (the Z axial direction) in Fig. 2, and a pair of connecting members 4, for connecting the pair of horizontal wings 2, provided extending in the X-Z plane in Fig. 2, in parallel so as to be a prescribed distance apart in the crosswise direction (the Y axial direction) in Fig. 1. Moreover, the drone 1 includes multiple propulsion units 6 (e.g., four propulsion units 6 as shown), attached to the end portions on both sides, in the crosswise direction (the Y axial direction in Fig. 1) of the pair of horizontal wings 2. The pair of horizontal wings 2, can be streamlined or configured as airfoils so as to produce lift during level flight, where the leading tip end portion (the nose side or toward the front in the X axial direction) has a curved shape, and the trailing end portion (the tail side or toward the rear in the X axial direction) has a shape that is more pointed than the tip end. The pair of connecting members 4 are attached so as to connect between the horizontal wings 2 at positions at equal distances to the left and the right from the center of the two horizontal wings 2. The pair of connecting members 4 have streamlined shapes or are airfoils, extending in the direction of flight. The pod 10 in the first example, when attached to the drone 1, is secured between the pair of connecting members 4, positioned between the pair of horizontal wings 2.

[0205] Each of the propulsion units 6, depicted in Fig. 1 and Fig. 2, comprises: a propulsion unit main unit 6A, a propeller 6D that is attached to the front end portion (the end portion on the nose side or to the front in the X axial direction) of the propulsion unit main unit 6A; a pair of horizontal tail wings 6B that are provided extending to both sides in the crosswise direction (the Y axial direction) from the back end portions (the end portions on the tail side or to the rear in the X axial direction) of the propulsion unit main units 6A; and vertical tail wings 6C, provided extending in the vertical direction (the Z axial direction) from the back end portions of the propulsion unit main units 6A. Each propeller 6D is attached to a propulsion unit main unit 6A so as to be able to rotate centered on an axle in the Y axial direction. Moreover, each horizontal tail wing 6B is attached to a propulsion unit main unit 6A, so as to enable the angle, relative to the X-Y plane (the horizontal plane during level flight) thereof to be adjusted independently. Each vertical tail wing 6C is structured so as to enable the angle thereof, in respect to the X-Z plane (the vertical plane in the front/rear direction during level flight) to be varied. Each propulsion unit 6 is equipped with a controlling device 6E, where the angle and rotational speed of the propeller 6D, the angle of the horizontal tail wing 6B, and the angle of the vertical tail wing 6C, of the individual propulsion unit 6, is controlled by the controlling device 6E.

[0206] The drone 1 depicted in Fig. 1 lands in a state wherein the propeller 6D of the propulsion unit 6 is positioned to the top, and the back end portion of the propulsion unit 6, which is equipped with the horizontal tail wing 6B and the vertical tail wing 6C, is in contact with the ground. When taking off, launching is through rotating the propeller 6D in a state wherein the propeller 6D is toward the top. Given this, the drone 1 is transitioned to level flight, where the X axial direction in Fig. 2 becomes the horizontal direction, through changing the angle of the propeller 6D and adjusting the angle of the horizontal tail wing 6B during flight. In the state of level flying, the nose portion is positioned in the forward horizontal direction, and the tail portion is positioned in the rearward horizontal direction. The propeller 6D is rotated to propel the body forward, to cause lift to act on the horizontal wing 2. Moreover, through changing the angle of the rotary shaft of the propeller 6D and adjusting the angle of the horizontal tail wings 6B from that of the state of level flying, the nose portion is positioned in the upper vertical direction, and the tail portion is positioned in the downward vertical direction, to transition to the landing state. Given this, the speed of rotation of the propeller 6D is adjusted to gradually move downward, to land by causing the back end portions of the propulsion units 6 to contact the ground.

[0207] Fig. 3 and Fig. 4 are partial cross-sectional drawing depicting enlargements of the body of a drone in a drone system of the first example, and the pod connecting portion, where Fig. 3 shows a cross-section that is parallel to the connecting member (X-Z plane), and Fig. 4 shows a cross-section that is parallel to the horizontal wing (X-Y plane). As illustrated in Fig. 3 and Fig. 4, the pod 10 comprises: a pair of guide rails 8, as installing and/or removing mechanisms 14 for securing removably to the drone 1; sliders 14A and 14B, provided on the side portions of the pod 10 (the pod case 12); and securing pins 15 for securing the pod 10 (the pod case 12) to the guide rails 8. Each guide rail 8 is structured from a long hollow material, having a rectangular cross-section, having a slit 8A, which extends in the lengthwise direction, formed in one face thereof. The two guide rails 8 are connected to the middle portions (the middle portion in the Z direction) of the connecting member 4, extending in the front/rear direction (the X axial direction), between the horizontal wings 2, with the faces wherein the slits 8A are formed in the guide rails 8 facing each other. Moreover, the pairs of sliders 14A and 14B are arranged so as to be lined up in the direction of the lengthwise axis L (Fig. 5) of the Z axial-direction middle portion of each side wall 22 of the pod case 12. Each slider 14A and 14B has a circular column-shaped shaft portion that is connected perpendicularly to the side wall 22, and a nose portion, provided at the tip end of the shaft portion, that has a larger diameter than the shaft portion.

[0208] When the pod 10 is attached to the drone 1, as depicted in Fig. 3 and Fig. 4, the sliders 14A and 14B of the side walls 22 of the mechanisms 14 are positioned within the guide rails 8. Given this, the securing pins 15 are inserted through the connecting members 4 from the outsides of the connecting members 4, and the tip ends thereof are inserted into the pod case 12. The pod 10 is secured to the drone 1 in this state. Note that the structure instead may be such that the securing pins are provided on the inside of the pod case 12, to be inserted into the guide rails 8 from the inside of the pod case 12 toward the outsides, to secure the pod 10 to the connecting members 4 that are secured to the guide rails 8. In this case, the securing pin may be of a tabbed shape, and provided in the pod case 12 so as to be secured through engaging the guide rail 8 through the tab through rotation. Moreover, the securing pins may be of tabbed shapes and provided within the guide rails 8, and may be structured so as to secure the pod case 12, through engaging as tabs, through rotation.

[0209] Through securing in this way, when the drone 1 moves upward or moves downward at the time of takeoff or landing, the pod 10 will move upward together with the drone 1 in a state wherein the nose portion of the pod 10 is upward. Moreover, when the drone 1 transitions to level flight, the lengthwise axis L of the pod 10 will also rotate, together with the drone 1, so as to be essentially horizontal. Given this, when the drone 1 engages in level flight, the pod 10 will also move, together with the drone 1, with the lengthwise axis L in essentially the horizontal state.

[0210] In the present example, the guide rails 8 are attached removably to the drone. In this way, when the guide rails 8 are attached so as to be removable from the drone 1, the guide rails 8 may also be included as a portion of the mechanism 14 that is provided in the pod 10. In such a pod, the guide rails 8 may be attached to a drone of a different model, if necessary, and can be attached to equipment other than a drone, as the transporting apparatus for the pod. Moreover, instead of a mechanism structured using the guide rails, sliders, and securing pins, described above, the mechanism may be an electric or manual mechanism having a structure using the addition of gears, hydraulics, screws (threaded shafts), and/or springs. That is, the structure of the mechanism need only be structured so as to enable the pod 10 to be secured to the drone 1 removably. However, when the drone 1 is of a tail-sitter type, preferably there is a function for guiding the pod in the vertical direction in relation to the drone when on the ground.

[0211] Fig. 5 and Fig. 6 are lengthwise-direction cross-sectional drawings depicting a pod according to an example, where Fig. 5 depicts the state wherein the supporting mechanism 16 is stored, and Fig. 6 depicts the state wherein the supporting mechanism 16 is deployed and in contact with the ground. As illustrated in Fig. 5 and Fig. 6, the pod 10 includes a pod case 12, a supporting mechanism 16 that supports the pod case 12 when removed from the body of the drone and in contact with the ground, and a mechanism 14 into and/or out of the drone 1, equipped in the pod case 12. In the same way as in the drone 1 depicted in Fig. 1, in the pod 10, the upper portion, in the X axial direction, in Fig. 1, that is, the part that is positioned toward the top of the lengthwise axis L in Fig. 5, is termed the “nose portion” of the pod 10, and downward in the X axial direction, that is, the part positioned toward the bottom of the lengthwise axis L is termed the“tail portion” of the pod 10

[0212] When on the ground in Fig. 6, the pod 10 stands with the lengthwise axis L having an angle a of between about 30° and 60°, and preferably about 45°, in relation to the surface of the ground. In the pod 10 that is depicted in Fig. 6, the upward portion in the figure, using the lengthwise axis L as the boundary, is termed the "back" of the pod 10, and the part that is downward in the figure is termed the "belly" of the pod 10. The supporting mechanism 16 has main landing gear 34, main wheels 36, and trailing wheels 48. In the state where the pod 10 is on the ground, depicted in Fig. 6, the direction in which the main wheels 36 are positioned, in respect to the trailing wheels 48, is termed the main wheel direction, and the direction in which the trailing wheels 48 are positioned in respect to the main wheels 36 is termed the trailing wheel direction. Fig. 7 and Fig. 8 are elevations depicting the pod 10 of an example, where Fig. 7 is an elevation when viewed facing the main wheel direction, and Fig. 8 is an elevation when viewed facing the trailing wheel direction.

[0213] Pod 10 can also include pod cargo chamber, including a main cargo chamber 18 and secondary cargo chamber 20. The pod cargo chamber can be accessible from the operator location or either side of the pod 10. A lid for pod cargo chamber can include an aerodynamic surface (e.g., be in a shape of an airfoil). As depicted in Fig. 5, main cargo chamber 18 and secondary cargo chamber 20, for storing cargo, are formed in the interior of the pod case 12 of the pod 10, and the pod case 12 overall has a long thin shape that extends from the nose portion toward the tail portion along the lengthwise axis L. The cargo chambers 18, 20, in certain examples, can be configured as a single chamber, or divided into further chambers, depending on the nature of the cargo being transported. Letter-sized packages can be compartmentalized differently from box-shaped packages. In addition, either cargo chamber 18, 20 can be specialized for specific cargo, for example, insulated or temperature controlled for shipment of temperature sensitive packages, e.g. cargo that needs to remain at cold temperatures.

[0214] Note that, as a whole, the pod case 12 may have a flat shape, in which case the direction that connects the nose portion and the tail portion would be the axis. Moreover, the pod case 12 has a streamlined shape, in the cross-sectional shape when viewed from the side. Specifically, in the pod case 12, the nose portion is bent in a curved shape, and the pod case 12 narrows from the center toward the tail portion along the lengthwise axis. Note that the cross-sectional shape of the pod 12 may be a teardrop shape, having the shape depicted in Fig. 15 A, an airfoil having the shape depicted in Fig. 15B, or an airfoil that has vertical symmetry, having the shape depicted in Fig. 15C. The pod case 12, as illustrated in Fig. 5 through Fig. 8, comprises a pair of side walls 22 that are positioned on both sides in the crosswise direction of the pod 10 (the Y axial direction), a back wall 24 that is provided so as to connect the back edges of the pair of side walls 22, a belly wall 26 that is provided connecting the belly side edges of the pair of side walls 22, and interior walls 28A, 28B, and 28C, which define the main cargo chamber 18 and the secondary cargo chamber 20. For reinforcement, there may be ribs 30 that extend from the tail side of the secondary cargo chamber 20 to the tail portion of the pod case 12. Note that the ribs 30 are provided for reinforcing the pod 10, and may not necessarily be essential members.

[0215] As depicted in Fig. 5 and Fig. 6, a storing portion 32 of a recessed shape, corresponding to the main landing gear 34 and the main wheels 36, is formed in the belly of the nose side of the pod case 12, and, as described below, the main landing gear 34 and main wheel 36 are stored in this storing portion 32. The pod case 12 has a main landing gear cover 38, where the main landing gear cover 38 is shaped so as to form a continuous surface with the belly wall 26 of the pod case 12 in the state wherein the main landing gear 34 and the main wheels 36 are stored in the storing portion 32.

[0216] The main cargo chamber 18 and the secondary cargo chamber 20 are partitioned by a dividing plate 40. The position corresponding to the main cargo chamber 18 and the secondary cargo chamber 20, to the front of the back portion of the pod case 12, is an opening, and a cargo chamber door 42 is attached to this opening. The cargo chamber door 42 can open to a horizontal position and be capable of supporting a load of approximately about 15kg in this position. The cargo chamber door 42 can be fited with a manually operated latch system that retains the door 42 in multiple locations. In one example, the door 42 can be retained in at least three locations: one on each side and one in the center of the door 42 on the side opposite the hinge. The car cargo chamber door 42 can be sealed with a gasket. Further, the cargo chamber door 42 can be sectioned to permit access to on one or the other of the cargo chambers 18, 20.

[0217] The tail side edge of the cargo chamber door 42 is connected to the pod case 12 so as to be able to swing, and a knob 42A, for opening/closing, is provided toward the forward end thereof. The cargo chamber door 48 is able to swing between a stored state, wherein the opening of the pod case 12 is closed, and an open state, rotated by about 90° toward the tail side from the stored state, to be essentially perpendicular in relation to the surface of the pod case 12. When the cargo chamber door 42 is in the opened state, the top face of the cargo chamber door 42 can be used as a place to temporarily place cargo. In order to use the cargo chamber door 42 as a place for temporarily placing cargo, preferably in the state wherein the pod 10 is placed on the ground (a state wherein the lengthwise axis L is inclined), the cargo chamber door 42 is opened to a state wherein a flat portion of the cargo chamber door 42 is horizontal, as opposed to the vertical direction (depicted by the double doted line in Fig. 6), and preferably does not open further than the horizontal state.

[0218] The dividing plate 40 is structured so as to be able to move in the front/rear direction along the lengthwise axis L direction. Depending on the weight of the cargo that is loaded into the main cargo chamber 18 and the secondary cargo chamber 20, the position of the dividing plate 40 can be moved so that the weight of the cargo will be at a prescribed position in the front/rear direction. This structure may use, for example, a configuration wherein a plurality of securing members for the dividing plate 40 are provided in the front/rear direction within the main cargo chamber 18 and the secondary cargo chamber 20, where the securing members for securing the dividing plate 40 are adjustable. While, in the present example, the dividing plate 40 is moved manually, there is no limitation thereto, but rather weight measuring devices may be provided in the main cargo chamber 18 and the secondary cargo chamber 20, and the position of the dividing plate 40 may be adjusted automatically. The position of the cargo may be adjusted through changing the position of the dividing plate 40, enabling the position of the centroid to be adjusted.

[0219] The pair of trailing wheels (first wheels) 48 that are atached to the tail portion of the pod case 12, and the pair of main wheels (second wheels) 36, that are atached to the tip end of the main landing gear 34, depicted in Fig. 5 through Fig. 8, structure the set of wheels that are included in the supporting mechanism 16 for supporting the pod case 12.

[0220] The main landing gear 34 is attached to the pod case 12 so as to enable storing in the forward belly of the pod case 12. As depicted in Fig. 5, the main landing gear 34 comprises: a pair of main landing gear main units 34A, provided separated in the crosswise direction (the horizontal direction), so that the base end portions will be positioned at the tail side when in the state wherein they are stored in the storing portion 32; and a shaft 34B that is provided so as to extend in the crosswise direction (the horizontal direction) to the tip ends of the main landing gear main units 34A, on which the main wheels 36 are provided. In each of the main landing gear main units 34A, the base end portion is connected to the belly of the pod case 12 through a hinge 34D that enables rotation in the front/rear direction. As illustrated in Fig. 6, the main landing gear 34 can be deployed through rotation to the tail side of the pod case 12. With the main landing gear 34 in the deployed state, the pod 10 is supported by the main landing gear 34 so that the lengthwise axis L forms an angle a with the surface of the ground. The shaft 34B is secured to the tip end portions of the main landing gear main units 34A, and the pair of main wheels 36 are equipped on both end portions of this shaft 34B so as to be able to rotate in respect to this shaft 34B. At the centers of the tip end portions of the main landing gear main units 34A, stoppers 34C are provided, where the pair of main wheels 36 are secured, so as to not be able to rotate, through pressing the stoppers 34C with the foot.

[0221] The storing portion 32 that is formed in the pod case 12 is formed in a shape corresponding to the main landing gear 34 and the main wheel 36, so that when the main landing gear 34 is swung toward the pod case 12, the main landing gear 34 in the main wheels 36 can be contained within the storing portion 32. Moreover, a handle 50 is formed in the interior of the storing portion 32. This handle 50 may be pulled as-is, or an extension that is provided by the user may be attached. The handle 50 or the extension may be pulled to move the pod 10 forward and backward, and to the left and the right, and to turn the pod 10. Note that while, in the present example, the handle 50 is secured to the pod case 12, the structure may be one wherein it may be attached to the pod case 12 removably instead. A main landing gear cover 38 is attached to the outer surface side of the main landing gear 34 when the main landing gear 34 is stored within the pod case 12, and when the main landing gear 34 and the main wheels 36 are contained within the storing portion 32, the main landing gear cover 38 forms a surface that is continuous with the outer peripheral surface of the pod case 12. Cover 38 can be a support structure for wheels 36 and include an aerodynamic profile (e.g., that of an airfoil) when pod 10 is closed. This may be achieved via a separate retractable cover.

[0222] In some examples, handle 50 can be detachable from the pod 10 without the use of secondary tools. Handle 50 can be moveable between a plurality of fixed positions (e.g., locked at heights of 850-950 mm from the ground). Handle 50 in some examples can extend between 200- 300 mm from the rear axle pivot location and accessible by a user so as to reach stopper 34C with both hands on the handle 50. Handle 50 can include rubber handgrips and be designed to allow the pod 10 to be moved on paved surfaces by a single operator using both hands on grades (e.g., up to 30% up hill and downhill).

[0223] In some examples, handle 50 can include one or more secondary latches on each side that prevents it being accidentally detached from the pod 10 during ground operations. In some examples, said one or more secondary latches can engage automatically when the handle 50 is attached, but also include a manual release for detaching therefrom.

[0224] In this way, in the present example, the main landing gear 34 is stored toward the front (the nose portion), and the main wheels 36 are positioned toward the front of the pod 10, making it possible to maintain the balance of the center of gravity toward the front during flight. Moreover, because the main landing gear 34 and the main wheels 36 can be stored completely within the pod case 12, through the main landing gear cover 38, this can reduce the air resistance and air separation during flight.

[0225] A method for removing the pod 10 from the drone 1 will be explained next. Fig. 9 through Fig. 14 are diagrams for explaining a method for removing the pod of the first example from a drone. First, as depicted in Fig. 9, when the drone 1 lands at a prescribed takeoff/landing site, the user pulls the securing pins 15 (see Figs. 3 & 4) from the pod case 12, thereby releasing the pod 10 and enabling the pod case 12 to move in the vertical direction, with the sliders 14A and 14B guided within the guide rails 8.

[0226] Next, as depicted in Fig. 10, the trailing wheel covers 52 are rotated to the back side, exposing the trailing wheels 48. When, in this state, the pod 10 is moved downward, then, as depicted in Fig. 11, the bottom sliders 14B will come out of the guide rails 8, and the trailing wheels 48 will contact the surface of the ground G. Once the trailing wheels 48 have come into contact with the ground G, in this state the pod 10 is moved downward, and the user pushes the tail portion of the pod 10 toward the back from the belly side. Through this, the pod 10 begins to rotate to cause the lengthwise axis L to be inclined from the vertical direction, so that the belly will be positioned downward, as depicted in Fig. 12. It is understood that covers 52, 38 shown and described in this disclosure, including those of subsequent figures, can include one or more quick release pins so respective covers can quickly release from a collapsed, flight configuration to a deployed, expanded configuration.

[0227] Next, as depicted in Fig. 13, the main landing gear 34 is rotated to a deployed state that is essentially perpendicular in respect to the belly, and secured there. Following this, the pod case 12 is further inclined, to cause the top sliders 14A to come out of the guide rails 8, and to cause the main wheels 36 to contact the ground. Through this, as depicted in Fig. 14, the trailing wheels 48 and the main wheels 36 of the supporting mechanism 16 can be brought into contact with the ground, to cause the pod 10 to be placed on the ground. In this way, deploying the main landing gear 34 holds the main wheels 36 in a position away from the pod case 12, so that the pod case 12 is supported, by the supporting mechanism 16, in a state wherein the lengthwise axis L is inclined relative to the landing surface. In this state the pod case 12 is supported with the lengthwise axis L at an incline in respect to the landing surface, the cargo chamber door 42 is opened, as depicted in Fig. 6, and cargo is removed from the main cargo chamber 18 and the secondary cargo chamber 20, and new cargo is loaded therein. At this time, as described above, the top face of the cargo chamber door 42 can be used as a place for placing the cargo temporarily. Note that when, for example, there is little cargo, the dividing plate 40 can be moved forward along the direction of the lengthwise axis L, enabling loading so that the center of gravity of the cargo that is loaded in the main cargo chamber 18 will be positioned toward the front of the main cargo chamber 18. Moving the dividing plate 40 in this way makes it possible to prevent movement of the cargo during flight, and also to possession the center of gravity of the pod 10 toward the front, making it possible to achieve stabilized flight. Note that equipping the pod 10 into the drone 1 may be performed through carrying out the steps for removal in reverse. Further equipping and removal can either be a manual or automated process, or a combination of both.

[0228] Note that after the pod 10 has been landed in this way, then, if necessary, the user attaches the extension to the handle 50. With the pod 10 positioned on the ground, the main wheels 36 and the trailing wheels 48 (the set of wheels) are in contact with the ground, and thus the pod 10 can be used as a cart that is pushed manually for transportation over the ground, through pulling the handle. Moreover, if, while transporting over the ground, one wishes to lock the swiveling of the trailing wheels 48 of the pod 10, the swiveling of the trailing wheels 48 can be locked through activating the locking mechanism 56 by pressing the lock button 56A that is depicted in Fig. 8. Moreover, the stoppers 34C, depicted in Fig. 6 and Fig. 7, can be pressed with the foot, to stop the rotation of the pair of main wheels 36, to stop the pod 10.

[0229] In some examples, stoppers 34C can be configured to prevent a fully loaded pod 10 from rolling from a stopped position on a grade of 30% both uphill and downhill. Stopper 34C can also be configured to operate on trailing wheels 48 simultaneously and be actuated by a foot operated control. The foot control can be operable from either side of the axle. The foot control can be retained in the ‘applied’ position by a secondary latch releasable by the foot operated control positioned towards a center line of the pod 10 and accessible by either operator foot. In some examples, a direction of motion for the control actuator used to actuate stoppers 34C can be largely vertical with an application force of less than approximately about 294 N (i.e. 30 kg). A direction of motion to release the stoppers 34C can range between vertically downwards and 45 deg to the vertical with an application force of less than approximately about 147 N (i.e. 15 kg).

[0230] Furthermore, the guide rails 8 in the mechanism 14 of the pod 10 may be attached to transporting equipment, such as an unmanned airplane, a four-wheeled vehicle, a two-wheeled vehicle, a railway, or the like, to enable the pod 10 to be secured to these, or other, transporting equipment. Reloading into these transporting apparatuses after the drone 1 has landed is also a possibility.

[0231] The effects through the example, as described above, are described below. Up to this point, pods for drones, having structures that take into account efficiency and effectiveness in, for example, user operations, preventing damage to cargo, long-distance movement, installation/removal operations, and the like, have not existed, and drone systems that use such pods have also not existed heretofore. Moreover, pods that are structured so as to enable such pods for use with drones to be transported by pod transporting equipment other than drones have also not existed in the past.

[0232] In the present example, when the pod 10 is removed from the drone 1 and placed on the ground, the pod case 12 is supported, by the supporting mechanism 16, in a state wherein the lengthwise axis L is inclined in respect to the surface of the ground. Thus it is possible to for the user to carry out the cargo loading and unloading operations with less bending and stooping than if the lengthwise axis L of the pod case 12 were placed level with the ground. Moreover, because the cargo is loaded in a state wherein the lengthwise axis L of the pod 10 is inclined by a degrees in respect to the surface of the ground, this can prevent damage to the cargo during flight of the drone 1 to which the pod 10 is attached because neither the horizontal angle a degrees of the cargo, nor 90°- a degrees, will greatly exceed a large angle, regardless of whether the pod 10 is stationary or being transported in a state wherein the lengthwise axis L of the pod 10 is either in the vertical direction or the horizontal direction.

[0233] Moreover, in the present example damage to the cargo can be prevented through the orientation of the cargo not changing by more than 90° from the time of loading, neither during level flight nor during takeoff and landing, despite the drone 1 to which the pod 10 is attached being a tail-sitter drone, through loading the cargo in a state wherein the lengthwise axis L of the pod 10 is inclined in relation to the landing surface.

[0234] Moreover, in the present example the pod 10 has a streamlined shape extending in the direction of the lengthwise axis L, and thus the air resistance of the pod 10 while the drone 1 is flying will be small, enabling long-distance transportation. Moreover, while in the present example the shape is a streamlined shape, there is no limitation thereto, but rather the same effect will be produced through a teardrop shape, an airfoil shape, or a vertically symmetrical airfoil as well.

[0235] Moreover, the pod 10 according to the present disclosure is attached to the body of the drone 1 so as to be positioned with the tail portion of the pod 10 downward, with the lengthwise axis L thereof extending in the X axial vertical direction, in the state wherein the drone 1 is on the ground. This causes the direction of travel of the drone 1 at takeoff and landing to be identical to the direction of the lengthwise axis L, so that the air resistance of the pod case 12 can be small, enabling long-distance transportation. Moreover, when removed from the drone 1, the pod case 12 can be supported, by the supporting mechanism 16, in a state wherein the lengthwise axis L is inclined in respect to the landing surface, and thus the difference in orientation of the pod 10 between the state wherein it is attached to the body of the drone 1 and the state wherein it is removed will be less than for a case wherein the pod case 12 is supported in a non-inclined state, enabling the operations for installing and removing the pod 10 to/from the drone 1 to be carried out easily.

[0236] In some examples, the pod 10 can be loaded or attached to the drone as follows. First, the pod 10 can be approached on its loading side. The pod 10 can then be pushed under the airframe and be manually aligned with engagement points thereon. The pod 10 is then engaged to the airframe, including with engagement point latches if necessary. Handle 50 can be attached or detached. A lifting mechanism can be deployed and the operator can then confirm if the lift process has been completed and pod 10 is correctly attached to the airframe. [0237] In some examples, the pod 10 can be unloaded or detached from the drone as follows. First, any secondary locks that may have been engaged during loading can be released. A lowering mechanism can then be deployed whereby the lowering process can then be confirmed whether complete. Once complete, handle 50 can be attached to the pod 10 and any applicable engagement latches can be actuated for release. Pod 10 can then be moved by handle 50 (e.g., pulled) from the drone.

[0238] Moreover, in the present example, the supporting mechanism 16 has a set of wheels that is in contact with the ground when the pod 10 is removed from the drone 1, and thus the user will be able to transport the pod 10 easily over the ground, even when removed from the drone 1.

[0239] Moreover, in the present example, the set of wheels includes also trailing wheels 48 that are attached to the tail portion of the pod case 12. If, after landing of the drone 1, the pod 10 were removed from the drone 1 in a state wherein the lengthwise axis L of the pod case 12 extends in the vertical direction, there would be the danger of the tail portion of the pod case 12 striking the ground and becoming damaged. In contrast, in the present example, when removing from the drone 1, the trailing wheels 48 are first brought into contact with the ground, making it possible to prevent damage to the tail portion of the pod case 12. Furthermore, the pod 10 can be tilted and removed easily and safely from the drone 1 by pushing the tail portion of the pod case 12 in the horizontal direction toward the back, from the belly side, in the state wherein the trailing wheels 48 are in contact with the ground.

[0240] Moreover, because, in the present example, the structure is such that the trailing wheels 48 can be stored in the pod case 12, the air resistance during flight can be reduced through storing the trailing wheels 48 within the pod case 12 during flight. Moreover, this can also reduce the risk of parts falling off, or the like, during flight.

[0241] Moreover, in the present example the set of wheels of the pod 10 includes main wheels 36, that are supported in a position away from the pod case 12 through the main landing gear 34 that is attached further toward the nose side than the trailing wheels 48 of the pod 10. This enables the pod case 12 to be supported in a state wherein the nose side is positioned toward the top, in the state that the pod 10 has been removed from the drone 1. Moreover, when removing from the drone 1, support by the main landing gear 34 is in a state that is inclined so that the nose side of the pod case 12 will be positioned toward the top, so that there can be little difference in the orientation of the pod between the state wherein it is attached to the body of the drone 1 and the state wherein it has been removed. This enables the operations for attaching the pod 10 to the drone 1, and for removing it, from the drone 1 to be carried out easily.

[0242] Moreover, in the present example, the structure is such that the main landing gear 34 and the main wheels 36 can be stored in the pod case 12. This makes it possible to store the main wheels 36 within the pod case 12 during flight, enabling a reduction in air resistance during flight. Moreover, this also enables a reduction in the risk of parts falling off, or the like, during flight.

[0243] With the pod 10 according to the present example, when on the ground, there is, on the nose side of the pod case 12, a handle for the user to pull and push, where this handle is attached removably to the pod case 12. This makes it possible to use the pod 10 as a transportation cart for transporting over the ground, through pushing or pulling the handle, in the state wherein the set of wheels is on the ground. In some examples, the lifting process can be implemented by engaging pins 15 into the guide rails 8, as well as setting any corresponding latches. Pivot arms can then be rotate to engage into pivot bearings on rails 8. Trailing wheel cover 152 can then be opened. Trailing and forward wheel axles can then be lifted until wheels 36 and 48 are clear of the ground. Wheels 36 and 48 can then be folded and trailing wheel cover 152 rear wheel cover closed shut.

[0244] Fig. 15 A depicts the contour of the teardrop shape of a pod. Fig. 15B depicts the contour of the airfoil shape of a pod. Fig. 15C depicts the contour of the symmetrical top and bottom airfoil shape of a pod.

[0245] Figs. 16A to 16B depict a perspective view of example shape of pod 10 with a symmetric airfoil shape. However, other pod shapes, including other airfoils, are contemplated for use with the solution of this disclosure and as shown in Figs. 15A-15C. An example chord length of 46 inches is shown in Figs. 16A to 16B, with a fixed R50 radius on side faces, mitered at the tail section. However, different chord lengths, radii, and/or tail section shapes and designs are contemplated as needed or required.

[0246] In some examples, pod 10 can include a battery system B to be used to actuate the control mechanisms of pod 10. Battery system B can be sized to allow a minimum of 10 lift / lower cycles to be performed at ambient temperatures of -20 to +50 deg C. Battery system B can be a Li-ION pack, with a supply voltage between 12 and 36V. Battery system B can be protected from mechanical or liquid damage, and accessible from within the pod cargo chamber, including the main cargo chamber 18 and secondary cargo chamber 20. Battery system B can be fitted with a system to recharge the battery via a port accessible from the pod cargo chamber. A charger for battery system B can be internal to the pod 10, or connected separately. Battery system B can include a master disconnect switch, accessible from outside the pod 10.

[0247] In some examples, pod 10 can be fitted with a power distribution block (PDU) with circuit overcurrent protection (fuses / circuit breakers) for each independent circuit used, and a master fuse for the entire system. Fuses and circuit breakers can be protected from mechanical or fluid damage, and accessible from the pod cargo chamber. Wiring to individual components and sensors can be appropriately sized for the current to be carried and be retained to the structure with clips.

[0248] In some examples, pod 10 can also include a controller C for executing operations. In some examples, controller C can include a plurality of motor drivers (e.g., three) with bi-directional control of drive motors without a need for an encoder or stepper driver. A plurality of analog position sensors (e.g., a minimum of three) can be included as well to monitor rotary for the axle and door actuators, and linear for the lift rail. Such sensors can be voltage-based potentiometers whereby the lift rail position sensor can be a magnetic ‘absolute’ position encoder to meet the package constraints. Controller C can be positioned onto a bottom plate of the pod cargo chamber and be configured to operate with a 12- 16V DC as well as include diagnostic capabilities (e.g., for inputs and outputs, including Short to Ground (Neg), Short to Battery (Neg), Short to Ground (Pos), and Short to Battery (Pos)).

[0249] Turning to Fig. 17, a perspective view of an example pod 110 is shown according to an example wherein the supporting mechanism 116 is deployed and in contact with the ground. Fig. 18 is a perspective view of pod 110 where the supporting mechanism 116 is deployed and in contact with the ground while the chamber door 142 is in the collapsed configuration. Pod 110 includes a pod case 112, a supporting mechanism 116 that supports the pod case 112 (e.g., when removed from the body of a drone attached therewith and in contact with the ground). When on the ground in Fig. 17, the pod 110 stands with the lengthwise axis L having an angle a of between about 30° and 60°, and preferably about 45°, in relation to the surface of the ground. Supporting mechanism 116 has main landing gear 134, main wheels 136, and trailing wheels 148.

[0250] Pod 110 can also include a pod cargo chamber, including a main cargo chamber 118, which can be configured to house a variety of contents (e.g., an article the size of a conventional carry-on bag). The pod cargo chamber of pod 110 can be accessible from the operator location or either side of the pod 110. A lid for pod cargo chamber can include an aerodynamic surface (e.g., be in a shape of an airfoil). On the outer lateral surface of pod 110, a guide rail 108 can be positioned to facilitate lifting and/or movement of pod 110 between deployed and flight configurations. Adjacent a leading edge of pod 110 can also be alignment pin 114 which can be configured to align with a spider connector mechanism (e.g., mechanism 314 as more particularly discussed below). Pin 114 and associated bracket of pod 110 can be configured to slide or otherwise translate laterally between the leading and trailing edges of pod 110, as needed or required.

[0251] Pod 110 can also include chamber 120, which is configured as a single chamber, or can be divided into further chambers, depending on the nature of the cargo being transported. For example, letter-sized packages can be compartmentalized differently from box-shaped packages. In addition, either cargo chamber 120 can be configured for specific cargo such as typical carry-on luggage or other matters urgent packages (e.g., insulated or temperature controlled for shipment of temperature sensitive packages such as perishable food items, medicines, fragile tissue for a medical procedure, etc.). The cargo chamber door 142 can be fitted with an automated or manually operated latch system that retains the door 142 in multiple locations. In one example, the door 142 can be retained in at least three locations: one on each side and one in the center of the door 142 on the side opposite the hinge. The car cargo chamber door 142 can be sealed with a gasket. Further, the cargo chamber door 142 can be sectioned to permit access to on one or the other of the cargo chambers 118. The trailing edge of the cargo chamber door 142 is connected to the pod case 112 so as to be able to swing, and a knob 142A, for opening/closing, which can be provided along an inner and/or outer surface of door 142.

[0252] In Fig. 17, pod 110 is also shown with a linear guide rail system 180, which can include a ball screw drive. System 180 can include a locking pin with a resistance element (e.g., bias spring) to ensure that pins associated with mechanism 314 have the correct orientation relative to the lower latch on the rail 108. Examples of this are shown in close-up views later in this disclosure, such as in Figs. 49A to 50B. A drive system can be used with system 180, which can include a bevel drive box on the upper end of the ball screw and a cross shaft linking the two ball screws, with a bearing support on the lower end of the ball screw. The upper pivot pin in this embodiment can mount to a gearbox housing, which in turn can mount to the side plate of pod 110, ensuring that lift forces are reacted directly on to the ball screw. The motor in this example can be centrally mounted in at or adjacent the leading edge of the pod 110 and can drive the ball screws via the cross shaft.

[0253] Turning to Fig. 19A, an example pod 210 is shown with trailing wheels 248 that can include a wheel diameter of approximately about 80 mm for improved packaging. Wheels 248 are configured to fold inwardly and be actuated with a four-bar linkage system 249. Note that in Fig. 19A, the surface of the ground, in a state wherein the pod 210 is in contact with the ground. One or more trailing wheel covers 252 are attached (e.g., through a hinged connector or the like), to the trailing edge portion of the tail side. The one or more trailing wheel covers 252 are configured to be rotated about a hinged connector on pod 210 between deployed and collapsed configurations. The structure depicted in Fig. 19A makes it possible to switch between the deployed and collapsed configurations by allowing the trailing wheel 248 to be stored within the trailing wheel cover 252. The depicted example of Fig. 19A allows set the size and location of the trailing wheel 248 without having an effect on the trailing wheel cover 252.

[0254] Fig. 19B shows pod 210 with wheels 248 configured with a pull-up actuation with linear actuator system 249’. Fig. 19C shows another pod 210 where wheels 248 are configured with a pull-up actuation system 249” with linear actuator with reduced front offset / actuation distance and larger stowed package. Fig. 19D shows another pod 210 where wheels 248 are configured with a fold-under system 249”’ with wheels 248 rotating in the same direction as the cover 252. In some examples, closures for system 249, such as cover 252, can be configured to hingedly cover wheels 248 and to minimize drag in forward flight. For example, the center of mass can be 25-40% of the pod 210 length behind the nose in both loaded and unloaded conditions. When detached from the airframe, pod 210 can be configured to rest at an angle of approximately about 45 degrees to the ground, with the nose of pod 210 at the highest and rearmost point.

[0255] Fig. 20 shows a forward perspective view of one example pod 310 of this disclosure in an expanded configuration prior to attachment with an example drone 1. As discussed more particularly below, pod 310 of the depicted example is capable of being releasably attached to drone 1 and moving between expanded, landing-gear deployed configurations and a flight configuration with all respective doors for cargo and landing gear sealed shut for flight. The expanded configuration of Fig. 20 includes an operator handle and landing gear wheels deployed for moving pod 310 from drone 1 to some other location.

[0256] In this example, it can be seen that pod 310 is configured for vertical loading to drone 1 whereby drone 1 can be a vertical take-off and landing aircraft (eVTOL) configured drone, including but not limited to fixed-wing aircraft as well as helicopters and other aircraft with powered rotors (e.g., cyclogyros, cyclocopters, tiltrotors, etcl). However, the pods and corresponding loading systems of this disclosure are not so limited and can be configured for loading to a corresponding vehicle horizontally or some combination thereof, with any number and types of corresponding drones. Further, drone 1 can have any number of motors and be configured to takeoff and land in any number of configurations as needed or required (see e.g., Figs. 47A - 48B).

[0257] Fig. 21 A shows a perspective view pod 310 in the expanded configuration whereby pod 310 is shown in the expanded configuration underneath example drone 1 just prior to attachment. Fig. 21B shows a perspective view of an example frame 301 of drone 1 to which pod 310 is configured to attach. Frame 301 can include a plurality of elongate sections 360 vertically oriented prior to takeoff. A pair of lateral support sections 362 connected sections 360 and a pair of transverse spar sections 364 can be included connecting sections 362. Guide rails 308 can also be included with frame 301, as discussed more particularly below, for removably loading pod 310 from drone 1. Guide rails 308 can include one or more elongate sections with an inner slot through which a corresponding pin or connector of pod 310 can be guided between expanded and flight configurations, manually or otherwise. One end of the guide rail 308 can be open to permit pod 310 to be thereto, whereby an opposite end can be closed. Guide rails 308 can be positioned so as to stably connect and load opposing surfaces of pod 310. In some examples, frame 301 can include flanges connected thereon (e.g., welded, bolted, mounted, or otherwise fastened) with joints to allow assembly to be broken down for transport. In some examples, frame 301 can include four sections 360 that correspond to fuselage sections of drone 1.

[0258] Figs. 22A - 22B show forward and rear perspective views of pod 310 in a flight configuration following attachment with the example drone 1, which includes a plurality (e.g., four in the depicted example) of example drone members 1A with respective propulsion systems. In particular, Fig. 22A depicts a forward perspective view of the leading edge of pod 310 oriented forward in a flight configuration, aligned with correspondingly forwarded oriented systems of example drone 1. Fig. 22B in contrast shows the trailing edge and rear portions of pod 310 and drone 1 in a flight configuration. It is understood that the drone 1 and corresponding subsystems are merely demonstrative and not intended to limit the type of aircraft with which pod 310 can be used.

[0259] Fig. 23A depicts a side perspective view of example shape of pod 310 with an airfoil shape, while Fig. 23B depicts an opposite, side perspective view of the pod of Fig. 23 A, whereby each figure shows pod 310 with corresponding landing gear collapsed therein in the fight configuration, though unassembled to a drone 1. The pod 310 of Figs. 23 A to 23B show one example pod 310 with covers 338 and 342, similar to previously discussed covers 38 and 42, whereby their corresponding outer surfaces are substantially flush with the remainder of the profile of the outer surface of pod 310. [0260] Fig. 24A depicts a forward plan view of pod 310 while Fig. 24B depicts a rear plan view of pod 310. Pod 310 is shown comprising two opposed lateral, generally planar faces that include mechanism 314, which is sometimes referred herein as a spider bracket, spider connector, or bracket generally. Each planar face can include mechanism 314, which can be positioned at or adjacent a quarter-chord of the side, planar face profile of pod 310. However, the location of mechanism 314 can be adjusted or positioned elsewhere as needed or required, for example, to shift or otherwise control the center of gravity of the pod 310. Mechanism 314 can include a base plate 314B with a plurality of pins 314A selectively positioned and extended outwardly from the base plate 314B. The shape of the base plate 314B is shown as being triangular, though other shapes of mechanism 314 can be used (e.g., rectangular, polygonal, circular, etc.). In some examples, mechanism 314 can include three (3) pins that are attach to corresponding connectors of drone 1. Each pin 314A can include a base portion with a smaller diameter at or adjacent the base plate 314B and a connector portion opposite thereto with a larger diameter than at or adjacent the base plate.

[0261] Fig. 25A shows a perspective view of mechanism 314. Fig. 25B depicts mechanism 314 coupled to guide rail 308. Fig. 25C depicts mechanism 314 coupled to guide rail 308. As previously discussed, mechanism 314 can include a plurality of pins 314A that extend from base plate 314B. Each of pins 314A in Fig. 25B are seen linked to rail 308 and/or rail 309 so as to stably slide along rail 308 to facilitate lifting of pod 310 between configurations. Mechanism 314 can also include alignment hole 314C and/or corresponding pin 314D for aligning and/or connecting with pin 114 see, e.g., Figs. 17-18) to in turn permit mechanism 314 and corresponding pod 310 move along guide rail 309 and/or rail 308. In some examples, mechanism 314 can be spring loaded, rotatable, and/or lockable in one or more engagements. For example, mechanism 314 can include or be attached to a torsion spring to provide resistance and control between engagements whereby mechanism 314 can be configured to rotate-and-lock between configurations. This is particularly advantageous so pod 310 can move between locked or fixed configurations versus transitory configurations. Rail 309 is configured for mechanism 314 slidably connecting therewith to connect pod 310 to drone 1. In some examples, mechanism 314 can be moved along rail 309 from the deployed configuration to the flight configuration manually by the end user or automatically (e.g., through one or more motors rotating and/or moving pin 365 along rail 309 and/or rail 308).

[0262] In some examples, rail 309 can be structured from an elongated, rectangular cross-section with a guide slit 309A extended in a lengthwise direction. Pins 314A can be cylindrical or any other shaped cross section with a distal tip with a diameter than the remainder of pin 314A. As can be seen, pins 314A are configured to slideably connected on opposite portions of guide rail 309, including at least one pin 314A disposed outside of rail 309 while another pin 314A being slideably located in slit 309A. One or more of pins 314A can be disengaged from drone 1 by an operator pushing a release latch downwards.

[0263] Fig. 26A is a forward perspective view depicting an example rear axle brake system 470 for use with pod 410, whereby system 470 can be designed to mechanically prevent rotational actuation of landing gear wheels 436 of pod 410. Fig. 26B is a forward perspective view depicting an example brake release bracket 472 of system 470 of Fig. 26A. Bracket 472 is designed to accommodate center support for brake pedal 480 that can, upon application of a downward force on pedal 480, prevent wheels 436 from rotating. Pedal 480 can include a planar section with a predetermined width for accommodating a foot contact area. Bracket 472 can include brake wheel mounts 476 angled downwards from brake sections 474. Extended orthogonally therefrom can be elongate sections 477 that extend from opposite wheel sections of bracket 472 into brake pedal section 478. The shape and configuration of system 470 is only one approach and other shapes and configurations of system 470 are contemplated.

[0264] Fig. 27 is a rear perspective view depicting another example rear axle brake system 570 for use with pod 510, whereby system 570 can be designed to mechanically prevent rotational actuation of landing gear wheels 536 of pod 510. System 570 can include brake member 572 designed to accommodate center support for brake pedal 580 that can, upon application of a downward force on pedal 580, prevent wheels 536 from rotating. Pedal 580, similar to pedal 360, can include a planar section with a predetermined width for accommodating a foot contact area. Member 572 can include brake wheel sections 574 disposed a predetermined distance away from wheel 536 and operable to be actuated downwards upon downward movement from pedal 580.

[0265] As shown, section 574 can include a contact point constructed from a section angled downward towards wheel 536 from section 574 to contact wheel 536 to prevent rotation. System 570 can include axle connectors extended from supporting mechanism 516 that are in rotational engagement with wheels 536. Extended therefrom can be elongate sections 577 that extend from opposite wheel sections of member 572 towards brake pedal section 578. The shape and configuration of system 570 is only one approach and other shapes and configurations of system 570 are contemplated. [0266] Fig. 28A is a forward perspective view depicting an example rear axle brake system 770 for use with pod 710, whereby system 770 can be designed to mechanically prevent rotational actuation of landing gear wheels 736 of pod 710. Fig. 28B is a rear perspective view of system 770. System 770 can include brake member 772 designed to accommodate center support for brake pedal 780 that can, upon application of a downward force on pedal 780, prevent wheels 736 from rotating. Pedal 780, similar to pedals 480, 580, and 680, can include a planar section with a predetermined width for accommodating a foot contact area. Member 772 can include brake wheel sections 774 disposed a predetermined distance away from wheel 736 and operable to be actuated downwards upon downward movement from pedal 780.

[0267] As shown, section 774 can include a contact point constructed from a section angled downward towards wheel 736 from section 774 to contact wheel 736 to prevent rotation. System 770 can include axle connectors extended from supporting mechanism 716 that are in rotational engagement with wheels 736. Mechanism 716 can include a transverse foot actuator 782 extended between side supports with a connector 784 bridging actuator 782 with pedal 780. In turn, a user can simply apply a downward force to pedal 780 that in turn can be translated through connector 784 to actuator 784on actuator surface 782 which in turn can pivot about its own axis and cause connector 784 to pivot and urge system 770 place section 774 in contact with wheel 736 to prevent its movement. In some examples, connector 784 can be integrally formed with actuator 782 and be oriented upwards and away therefrom. In some examples, actuator 782 can be an elongate bar positioned below pedal 780 and release actuators.

[0268] Extended inwardly from mechanism 716 can be elongate sections 777 that extend from opposite wheel sections of member 772 towards brake pedal section 778. The shape and configuration of system 770 is only one approach and other shapes and configurations of system 770 are contemplated.

[0269] Fig. 29A is a forward perspective view depicting an example rear axle brake system 870 in a locked configuration for use with pod 810, whereby system 870 can be designed to mechanically prevent rotational actuation of landing gear wheels 836 of pod 810. Fig. 29B is a rear perspective view of system 870 in an open configuration for riding. System 870 can include brake member 872 designed to accommodate center support for brake pedal 880 that can, upon application of a downward force on pedal 880, prevent wheels 836 from rotating. Pedal 880, similar to pedals 480, 580, and 780, can include a planar section with a predetermined width for accommodating a foot contact area. Member 872 can include brake wheel sections 874 disposed a predetermined distance away from wheel 836 and operable to be actuated downwards upon downward movement from pedal 880. Pedal 880 can also be configured to pivot about an axis of connector 884 between a locked configuration in Fig. 28A and an unlocked configuration in Fig. 28B.

[0270] As shown, section 874 can include a contact point constructed from a section angled downward towards wheel 836 from section 874 to contact wheel 836 to prevent rotation. System 870 can include axle connectors extended from supporting mechanism 816 that are in rotational engagement with wheels 836. Mechanism 816 can include a transverse foot actuator 882 extended between side supports with a connector 884 bridging actuator 882 with pedal 880. In turn, a user can simply apply a downward force to pedal 880 that in turn can be translated through connector 884 to actuator 884on actuator surface 882 which in turn can pivot about its own axis and cause connector 884 to pivot and urge system 870 place section 874 in contact with wheel 836 to prevent its movement. In some examples, connector 884 can be integrally formed with actuator 882 and be oriented upwards and away therefrom. In some examples, actuator 882 can be an elongate bar positioned adjacent and/or below pedal 880.

[0271] Extended inwardly from mechanism 816 can be elongate sections 877 that extend from opposite wheel sections of member 872 towards brake pedal section 878. The shape and configuration of system 870 is only one approach and other shapes and configurations of system 870 are contemplated.

[0272] In some examples, pedal 880 can include a notch 880A sized to slide around brake pedal section 878 of member 872 whereby when notch 880A is disposed around section 878 in the locked configuration, section 874 is incapable of being moved, including towards wheel 836. To release pedal 880, a release force can be applied to latch 880B thereby causing notch 880A to pivot about the axis of connector 884 and release from section 878.

[0273] Fig. 30A is a forward perspective view depicting system 870 with a landing gear cover 838 while Fig. 30B is a rear perspective view thereof. Main landing gear cover 838 is shaped to provide access to pedal 880 in the expanded configuration while also forming a continuous surface with the belly wall 826 of the pod case 812 when the main landing gear 834 and the main wheels 836 are stored in the storing portion 832.

[0274] Fig. 31A is a forward perspective close-up view depicting pod 810 having system 870 with cover 838 in an expanded configuration. Fig. 3 IB is a side plan view depicting pod 810 and system 870 of Fig. 31A in the expanded configuration. Fig. 31C is a side plan view depicting pod 810 and system 870 of Fig. 31A moving from the expanded configuration to the collapsed, flight configuration with all respective doors for cargo and landing gear, including cover 838 and door 842, sealed shut for flight. In some examples, the main landing gear wheel 834 pivot from an upper axle connected to linkage 860 and pivot thereabout until being stowed in main landing gear portion 832 of pod 810. Fig. 32A is a front plan view depicting pod 810 with trailing wheels in a collapsed, flight configuration and wheels 848 folded inwardly towards the other via the four-bar linkage. Fig. 32B is a side plan view of pod 810 with trailing wheels 848 and wheels 836 in the same configuration of Fig. 32A. Cover 852 has been moved to the collapsed, flight configuration to completely contain wheels 848 and corresponding linkage therein. In some examples, cover 852 is hingedly connected through a linkage or hinge-like member. Main landing gear wheels 836 conversely remain in an expanded configuration. In some examples, wheels 848 and corresponding four-bar linkage system 849 can be controlled by a rotational or a linear actuator that can also advantageously include efficient package space with flexibility for rotary or linear actuator. System 849 can include short actuation distance with relatively long offset from pod 810 to aid orientation of pod 810 during lowering.

[0275] Turning to Figs. 33A-33D is an example of another support system 949 for trailing wheels 948 of pod 910. As can be seen in Fig. 33 A, system 949 is disposed in a first configuration with wheels 948 oriented in a folded configuration. Though not shown, cover 952 can be capable of hingedly collapsing around system 949 and wheels 948 into a flight configuration. System 949 can include linkages 949C and 949B interconnected through system hub 949 A. Each linkage 949B, 949C can be elongate members with one or more connectors connecting one on end to respective wheel supports 949D and hub 949A on the opposite end. Each support 949D can include a joint to mount to the trailing edge of pod 910 and an elongate support member attached to wheel 848. Hub 949A is capable of rotating and driving linkages 949B, 949C to in turn cause supports 949D and wheels 948 to move between collapsed and flight configurations. For example, one or more of linkages 949B, 949C, or hub 949A can be belt driven, driven by a motor (e.g., gear motor) so as to drive system 949 between configurations.

[0276] Figs. 33B - 33D depict different perspective views of system 949 in pod 910 in an open, deployed configuration with linkages 949B, 949C extended outward. System 949 as shown is relatively simple, multi-bar (e.g., four [4]) and significant reduction in complexity. Advantageously, system 949 can use an offset between the height of the left and right support axles 949D to fold one under the other during deployment. In some examples, an amount of an offset can be adjusted manually or automatically (e.g., by adjusting a length of the linkage by a thread, a push fit connector, or telescoping system). As the linkages 949B, 949C move to the collapsed, flight configuration, cover 952 (not shown) and likewise be configured to pivot from the open to closed, flight configuration.. In some examples, both supports 949D can lock at the same time.

[0277] Turning to Figs. 34A-34C is an example of pod 1010 in an expanded configuration with handle system 1050 operated by end-user U. In particular, Fig. 34A shows a rear perspective view of pod 1010 of this disclosure with handle system 1050 and corresponding landing gear in an expanded configuration, whereby cargo chamber door 1042 of system 1050 is attached to a top hinge of pod 1010 and provides both upper and side access. Fig. 34B shows a forward perspective view and Fig. 34C shows a side plan view of the same pod 1010. As previously discussed in Fig. 6, pods of this disclosure can include a handle, formed with pod and stored in one or more of its cargo chambers or as a removable extension that can be attached by an end-user when required. In the depicted example of Figs. 34A-34C, handle system 1050 is a removably loadable extension at or adjacent the leading edge of pod 1010 that can be pulled to move pod 1010 forward and backward, and to the left and the right. In some examples, handle system 1050 can be positioned for a 900 mm target height concept and be configured so as to slide into pod 1010 under its cargo area. In this example, handle system 1050 can be partially or completely stowed under its cargo area and optionally include a separate slide system and cover plate.

[0278] In some examples, handle system 1050 can be integrated into the trailing wheel portion of pod 1010 (e.g., sharing pivot point with an axle of the trailing wheel portion). In this example, pod 1010 can include a release mechanism on lower part of trailing wheel landing gear legs (e.g., a quick release pin). In this example, an extension of handle system 1050 can fixed or height adjustable via a deployment pivot.

[0279] Turning to Figs. 35A-35C is an example of pod 1110 in an expanded configuration with handle system 1150 operated by end-user U. In particular, Fig. 35A shows a rear perspective view of pod 1110 of this disclosure with handle system 1150 and corresponding landing gear in an expanded configuration, whereby cargo chamber door 1142 of system 1150 is attached to a bottom hinge of pod 1110 and provides both upper and side access. Fig. 35B shows a forward perspective view and Fig. 35C shows a side plan view of the same pod 1110. As previously discussed in Fig. 6 and Figs. 34A-34C, pods of this disclosure can include a handle, formed with pod and stored in one or more of its cargo chambers or as a removably loadable extension that can be attached by an end-user when required. In the depicted example of Figs. 35A-35C, handle system 1150 is a removably loadable extension at or adjacent a leading edge of pod 1110 that can be pulled to move pod 1110 forward and backward, and to the left and the right. In some examples, handle system 1150, similar to system 1150, can be integrated into the trailing wheel portion of pod 1110 (e.g., shares pivot point with an axle of the trailing wheel portion). In this example, pod 1110 can include a release mechanism on lower part of trailing wheel landing gear legs and/or an extension of handle system 1150 can fixed or height adjustable via a deployment pivot.

[0280] Turning to Figs. 36A-36C is an example of pod 1310 in an expanded configuration with handle system 1250 operated by end-user U. In particular, Fig. 36A shows a rear perspective view of pod 1210 of this disclosure with handle system 1250 and corresponding landing gear in an expanded configuration, whereby cargo chamber door 1242 of system 1250 is fixedly positioned while side doors 1242A and 1242B are in an open configuration providing access to the main cargo bay for side access only. Fig. 36B shows a forward perspective view and Fig. 36C shows a side plan view of the same pod 1210. As previously discussed in Fig. 5, Figs. 34A-34C and Figs. 35A-35C, pods of this disclosure can include a handle, formed with pod and stored in one or more of its cargo chambers or as a removably loadable extension that can be attached by an end-user when required. In the depicted example of Figs. 36A-36C, handle system 1250 is a removably loadable extension that can be pulled to move pod 1210 forward and backward, and to the left and the right.

[0281] Turning to Figs. 37A-37B is an example of pod 1310 in an expanded configuration with handle system 1350 operated by end-user U. In particular, Fig. 37A shows a rear perspective view of pod 1310 of this disclosure with handle system 1350 and corresponding landing gear in an expanded configuration, whereby cargo chamber door 1342 of system 1350 is in a closed configuration. Handle 1350 is seen with mounts 1350A at the upper nose end of pod 1310 with elongate members 1350B extended outward and joined by a support bar / handle member 1350C, which is shown in Fig. 37A handled by user U. Mounts 1350A can be fixedly attached to pod 1310 or removably loaded thereto, including to a specific mounting position or a plurality of mounting positions of pod 1310, as needed or required.

[0282] Turning to Fig. 38, a close-up perspective view of pod 1450 is shown just prior to attachment with attachment system 1450. Handle system 1450 can include elongate members 1450C and 1450B along with corresponding mounts 1450A, as more clearly illustrated in Figs. 39A - 39C. While chamber door 1442 is depicted in an open configuration, it is understood system 1450 can be attached to pod 1410 with door 1442 in another closed, flight configuration..

[0283] Turning to Figs. 39A- 39C, close-up schematics of system 1450C attaching to pod 1410 is shown. In particular, Fig. 39A illustrates a close-up view of member 1450C just prior to engagement with pod 1410. In particular, member 1450C includes a lower attachment notch 1452A and an upper attachment notch 1452B. To operatively connected system 1450 to pod 14150, notch 1452A is aligned and engaged with lower receiving pin 1462A, as denoted by the downward arrow of Fig. 39A. Pin 1462A can be seen extruding from an inner, planar wall of pod 1410 adjacent a gear motor that is configured to drive pod 1410 between configurations. Turning to Fig. 39B, notch 1452A is now engaged with pin 1462A. Notch 1452B can now rotate about pin 1462A until contacting and engaging with upper receiving pin 1462B which is also seen extruding inwardly from the inner, planar wall of pod 1410. Fig. 39C shows notches 1452A, 1452B securely engaged with corresponding pins 1462A, 1462B, respectively. The depicted notches 1452A, 1452B can be operatively connected to a torsion spring S to hold one or both notches in a fixed engagement with pod 1410. In use, the operator using system 1450 can pushes one or both notches 1452A, 1452B downwards to disengage (e.g., from the upper pins 1462B or lower pins 1462A. Removing handle system 1450 from lower pin 1462A can be achieved by retracting the spring or corresponding resistance element and resetting a latch lever 1453 associated with one or both notches 1452A, 1452B. While Figs. 39A- 39C show only one latch lever 1453 and spring S associated with engagement between pin 1462B and notch 1452B, system 1450 is not so limited and instead another spring, latch system could be similarly used with notch 1452A.

[0284] Figs. 40A - 40C shows an example cross-sectional view of system 1450 previously shown in Figs. 39A- 39C, which includes spring S coupled with latch lever 1453 to hold it closed. As shown, latch 1453 can include one or more elongate sections terminating in a latched end configured to engage one of pins 1462B, 1462A. Latch lever 1453 can pivotally attach to a pin 1455 of member 1450C configured so latch lever 1453 can rotate between engaged and disengaged positions. Latch lever 1453 can include its own notch 1457 adjacent pin 1455 to engage with spring S. In a fixed engagement, notch 1457 engages with a corresponding latch surface of spring S, as shown in Fig. 40C. In use, the operator pushes latch 1453 downwards to disengage the upper pin 1462B and spring S engages with notch 1457, holding latch 1453 open. Removing handle 1450 from lower pin 1462A is achieved by the operator retracting and resetting the latch lever 1453. Location points on handle 1450, such as latch surface 1459, are configured to engage with pins 1462A. 1462B as well as pins associated with the drive axel of pod 1410 to adjust pod 1410 between configurations. Figs. 41A - 41C shows additional views of pod depicting system 1450 engagement via latch 1453 with pins 1462A, 1462B.

[0285] Turning to Figs. 42A-42B is an example of pod 1410 in an expanded configuration with handle system 1450 attached therewith. System 1450 can be seen engaged with the upper, leading edge of pod 1410. In particular, Fig. 42A shows a forward perspective view while Fig. 42B shows a rear perspective view of pod 1410 with system 1450 and corresponding features in expanded configurations. For example, cargo chamber door 1442 can be seen hingedly attached to pod 1410. In some examples, door 1442 can be integrated into side panels of pod 1410 with a two-point latch with single release catch.

[0286] Figs. 43A - 43B show a sequence of pod 1610 attaching to drone 1. In Fig. 43A, pod 1610 is shown in a side plan view with its landing gear wheels 1636, 1648 fully deployed. As shown, pod 1610 is configured to be selectively positioned at or adjacent a guide rail 1608 of drone 1 for installing and/or removing mechanisms 1614A of pod 1610 to drone 1. Positioning as well as installing of pod 1610 in this respect can be done manually by an operator, automatically by one or more sensors onboard pod 1610 configured to navigate pod 1610 to rail 1608, or some combination thereof. Rail 1608 can be removably or permanently attached to drone 1, which is advantageous as it permits pod 1610 to be installed with a variety of different drones 1. Mechanism 1614A can be positioned on the side portions of the pod 1610 and include a pin, screw, or the like, for slidably securing the pod 1610 to the guide rail 1608. Rail 1608 can include slit 1608A and pivot mechanism 1608B with ball screw collar. Mechanism 1608B can be configured to permit mechanism 1614B to pivot and angle from its orientation in Fig. 43A to the attached pre-flight configuration of Fig. 43B. Slit 1608A can extend in the lengthwise direction, similar to previously described rails 8 and slit 8A.

[0287] Fig. 44 shows a side plan view of pod 1710 of this disclosure in an expanded configuration prior to attachment with wing 2 of drone 1. Pod 1710 is shown in a side plan view with its landing gear wheels 1736, 1678 fully deployed. As shown, pod 1710 includes a guide rail 1708 for installing and/or removing mechanisms 1714A, 1714B for securing removably pod 1710 to drone 1. Mechanisms 1714A, 1714B can be positioned on the side portions of the pod 1710 and include a pin, screw, or the like, for slidably securing the pod 1710 to the guide rail 1710. Rail 1708 can include front 1708A and rear 1708B guides. Rear guide 1708B can be positioned above pinion center 1713 to allow pod 1710 to be loaded into rail 1708. Front guide 1708A can be below pinion center 1713 so pod 1710 can be loaded into rail 1708. Larger horizontal displacement from pinion 1713 to rear guide 1708B decreases load on guide 1708 limited by positioning pinion 1713 relatively close to pod center line CL and pin inside the curve of the side panel. Either pinion 1713 or one of guides 1708A, 1708B can have a mechanism for latching the guides to the guide pins 1714A, 1714B and/or retaining tension between rack 1708 and pinion 1713 during operation. Angle of guide 1708 A during transition can be set high enough and guide angle steep enough to prevent wheels 1748 from touching the ground.

[0288] In some example, guides 1708A, 1708B can include preloaded torsion or tension springs. Alternatively, preload may be applied to guide pins 1714A, 1714B. Front 1708A and rear 1708B guides can also include back-out cams at guide pin 1714A, 1714B entry points to latch pod 1710 to rail 1708. A toggle clamp could be used to manually apply a preload by pulling the pins 1714A, 1714B

[0289] In some examples, pod 1710 can be raised while maintaining approximately about a 10 mm clearance between moving parts of the pod 1710 and the airframe of drone 1. In some examples, a pod lift height from rest position is approximately about 770 mm. In some examples, pod 1710 can be manually positioned and engaged to airframe by user U. In some examples, latch points for initial engagement can be visible to the user and reachable either directly or via a secondary tool. From rest position, pod 1710 can attain a vertical orientation before reaching final lift height.

[0290] In some examples, during lifting operation, wheels 1736 can move laterally or upwards in order to support pod 1710. In some examples, during lifting operation, wheels 1736 may not generate an upward force on the airframe via the lifting assembly and actuation mechanism and power source for the lifting operation can be contained on-board pod 1710. The lift mechanism can have a minimum number of exposed parts.

[0291] Figs. 45A - 45E show a sequence of pod 1710 attaching to rail 1708 of wing 2. In the depicted sequence, pod 1710 is seen being attached with fixed angle control thereby eliminating a need for other potential features, including a separate reaction torque arm back to the rail. In particular, the method of loading shown in Figs. 45 A- 45E depicts pod 1710 attaching to rail 1708, which is attached to the airframe. One engaged with rail 1708, pod 1710 is driven by a lead screw attached to its spider mechanism (e.g., similar to mechanism 314) which is operatively coupled to a motor. The motor can drive pod 1710 until being driven to the end of rail 1708 in a pre-flight configuration, as shown in Fig. 45E. Pod 1710 can attach to rail 1708 of airframe using a variety of approaches, including a self-latching system. [0292] Figs. 46A - 46E show a sequence of pod 1910 attaching to rail 1908 of another example wing 2. In Fig. 46A, pod 1910 commences the sequence in an expanded configurations similar to prior approaches. Guide rail 1907 of pod 1910 can be seen attached to connector 1914B of mechanism 1914 (similar to spider mechanism 314) in Fig. 46B as forward connector 1914A, which is similar to mechanism 314 and its corresponding pins, engages a proximal end of guide 1908 beginning in Fig. 46C. Once engaged, between Figs. 46D - 46F, connector 1914A slides distally through guide 1908 until it reaches a distal most end of guide 1908 thereby properly aligning and lifting pod 1910 into a flight attachment configuration with wing. Proximal thereof and as pod 1910 is oriented between Figs. 46D - 46F, pod 1910 is pivoted about connector 1914B of rail 1907. While shown as separate pieces, it is contemplated that guide 1908 and rail 1907 can be a single, monolithic structure.

[0293] Figs. 47A to Fig. 48B show a sequence of an example pod attaching to rail of another drone. While Figs. 46A to 46F generally show pod 1910 attaching substantially vertically to drone 1, since rail 1908 is loaded and oriented with respect to wing 2 in a substantially upright, vertical manner since drone 1 is an eVTOL, the sequence shown between Figs. 47A to 48B is depicted being loaded of drone 1’ which is a more traditional short horizontal take off aircraft in a substantially horizontal manner. This is particularly advantageous as the corresponding drone 1 used with pod 1910’ does not necessarily have to be an aircraft configured for vertical take-off and/or landing but instead can be.

[0294] Figs. 49A - 49B show an example mechanism 2014, such as mechanism 314, in one step being attached to an example guide 2008 of drone 1. Pod 2010 is not shown strictly to illustrate how mechanism 2014 can engage with guide 2008. However, it is contemplated that mechanism 2014 would be positioned and connected with respect to pod 2010, similar to prior spider mechanisms and corresponding pods. In Fig. 49A, it can be seen that guide 2008 includes upper notch 2008C and lower notch 2008B. An upper pin 2014A can be upwardly translated (denoted by the upward arrow) into upper notch 2008C while a lower pin 2014A can be rotated into lower notch 2008B (denoted by the rotating arrow).

[0295] Fig. 50A shows a perspective view of mechanism 2014 engaged with latch 2013 (not depicted) disposed on a lower portion of rail 2008. Rail 2008 is shown attached to wing 2 of example drone 1. Opposite latch 2013, rail 2008 can include. Fig. 50B is merely a close-up view along section A-A of Fig. 50A. In use, once mechanism 2014 is aligned and engaged with latch 213 and any corresponding notches, pin 2065 can be aligned so as to initiate engagement in and along guide slit 2009A of rail 2009. Pin 2065, which would be disposed on an outer lateral surface of pod 2010, is shown in Fig. 50A now initiating engagement along guide slit 2009A, which can be structured from an elongated cross-section along the interior of rail 2009 and extended in a lengthwise direction. In Fig. 50B, the upward arrow denotes the direction of movement of pin 2065 once aligned and engaged with slit 2009A. Where the operator’s hand is shown in Fig. 50A handling pin 2065, the hand in reality would be replaced with the outer lateral surface of pod 2010. Pin 2065 can include a rotatable, bearing member rotatably attached to a pin or drive axel and operable to translate between configurations along slit 2009A. A motor can be disposed inside pod 2010 so as to drive and lift pin 2065 and/or mechanism 2014 between configurations. Pod 2010 is merely excluded from Fig. 50A so as to show the relationship of pin 2065 with respect to mechanism 2014, latch 2013, and rail 2008 during use. Fig. 51A shows pin 2065 of Figs. 50A - 50B now having been translated upwardly along slit 2009A of rail 2009 to the uppermost end 2009B. Fig. 5 IB shows a close-up along section B-B of Fig. 5 IB more clearly showing pin 2065 now at or adjacent end 2009B.

[0296] Figs. 52A - 52C shows an example pod 2110 which includes a mechanism 2153 operable for relatively fast initial acceleration of door 2138 to clear the axle as it starts moving. In some examples, mechanism 2153 can include at least three (3) links, though more or fewer are contemplated as needed or required. In some examples, if cover 2138 can be held closed with a resistance element (e.g., a spring, band, latch, hook, or friction inducing element) and the front axle can deploy by displacing the cover, which will then automatically close behind it. In some examples, a linkage can still be required to open cover 2138 as main landing gear wheels 2136 close.

[0297] Figs. 53 A - 53D shows pod 2210 moving between deployed (Fig. 53A) to collapsed (Fig. 53D) configurations. Pod 2210 includes cover 2252 of wheels 2248 linked to front axle actuation, small overtravel and return during operation necessary to maintain single link design. Similar to prior examples, pod 2210 includes mechanism 2253 which, similar to prior mechanism 2153, is operable for relatively fast initial acceleration of door 2238 to clear the front axle as it starts moving. In some examples, mechanism 2253 can include multiple links between members disposed internal to pod and door 2238. In some examples, if cover 2238 can be held closed with a resistance element (e.g., a spring, band, latch, hook, or friction inducing element) and the axle can deploy by displacing the cover, which will then automatically close behind it. In some examples, a linkage can still be required to open cover 2238 as main landing gear wheels 2236 close.

[0298] Fig. 54 depicts a method 5400 to attach a pod with an aircraft. The method 5400 can include 5410 engaging a forward connector of the pod with a guide rail of the aircraft. The method 5400 can also include 5420 engaging a rear connector of the pod with the aircraft. The method 5400 can also include 5430 distally moving the forward connector of the pod within the guide rail of the aircraft until the forward connector is aligned with a leading edge of a wing of the aircraft. In some examples, the aircraft can be an autonomous drone, an eVTOL, an aircraft configured to take off horizontally, a helicopter, and/or the like.
