The claimed technical solution belongs to machines and methods of driving bodies and may be applied in air and water carrier vehicles.

The claimed technical solution is based on a body drive operating principle of which may be described by repulsion from environment. In details the principle will be explained when integral parts of the body driver and the operating principle of the technical solution are described.

From technical background a solution of Festo company is known (http://www.upstreamnews.org/blog/2015/03/28/cooperative-ant s-and-swarming- butterflies-are-the-latest-in-insect-inspired-robotics/). According to the known facts, this solution presents a body drive which can move a body center in a medium by means of wings waving. With each wing wave an area of increased pressure is created in direction of the wing movement the irrespective of the wing movement direction itself. So, when the wing goes up, the body center moves down. In such movement the wing makes an additional wavelike motion to compensate movement of the body center down. This solution has a small rate of acoustic noise. However, it is not possible to keep a stable path, so it is impossible to apply this solution in conditions of turbulence or active weather.

From technical background ornithopter solutions are known which use wings to create a lifting force (https://tvrain.ru articles/ornitopter-412772/, https://www.youtube.com/watch?v=a-qS7oN-3tA). But these solutions cannot ensure precision maneuvering, in particular, hanging ('fading') in the environment.

Also, from technical background French patent FR129091 as of 1962 is known, which describes a vessel drive that has a frame connected to reciprocating motion drive gear. The frame has plates (blades) of different length which overlap one another in the working position forming a vertical wall.

This technical solution ensures a body movement in water environment. This drive has a large construction and rather a heavy weight. This construction cannot be considered sufficiently reliable due to its complexity. Also, a low capacity of maneuvering is another weak point of this known solution.

Further, cause-and-effect relationship will be described between the features of the claimed objects and the technical result. Since the claimed drive and method can be modified and have alternative implementations, the following description is given as an example to explain their key points and possibilities of implementations. It should be evident that the given detailed description should not limit the idea of the claimed technical solution only by the specified implementations, but on the contrary, it includes all modifications, equivalents and alternatives which fall under the essence and scope of the patent rights protection, which is described in the attached formula.

The claimed drive and method of body movement are intended to ensure body movement in the air and water working environments. To change the working environment neither the drive nor the method needs any additional changes or modifications and can be adapted to such changes within the limits of their inherent essential features. This implies extending functional capacities of the drive.

The claimed drive is attached to the housing of a body which needs to be moved. The body includes a water or air carriage. The below description should clearly explain to an expert in this field where and how the drive should be mounted. The body housing is made of materials typical for such devices. Some specific features of the housing construction related to the drive operation are described below.

The body drive has a drive mechanism rigidly attached to the housing. Following is the description of a construction with only one drive, but it should be clear for the experts that it is possible to use more than one drive with the body. The number of drives mounted on to the body depend on the targeting factors that describe the body movement, such as speed, carrying capacity, ability of maneuvering, etc. Possibility and order of using more than one drive on the same body housing is given below.

The drive mechanism is attached to a tool for lever movement. The drive mechanism is a source of energy which is directed at creating force applied to the first end of the lever to set it in motion.

Under the first implementation pictured at Fig. 1 , the drive mechanism is a rotary motor. A rotary moment created at the output of the rotary motor is applied to the tool for driving the lever. The lever can rotate when the force from the drive mechanism is applied to the lever first end. Fig. 1 shows a flywheel with a projected roller which is used as the tool to drive the lever. The projected roller is mainly located on the marginal end of the flywheel. Under this implementation, the first end of the lever has a cavity with the inserted projected roller. So, the specific feature of the projected roller is that it has a circle orbit, which means that it can move radially towards the flywheel axis. At the same time the projected roller can make reciprocating motion towards the lever axis, which ensures the lever swinging.

This implementation also assumes changing the lever swinging frequency and value of the force moment applied to the lever through a gear box mounted between the rotary motor and the flywheel as well as change of motor shaft speed. Change of frequency and the driving moment at the output of the gear box impacts both the lever movement frequency and the working body movement speed respectively.

Under another implementation pictured on Fig. 2, the drive mechanism is an electromagnetic field generator. Voltage is applied to the generator input through a controlled commutation device. Such device may include a relay switch, a commutator, a controller, etc. This commutation device is needed to control switching the voltage applied from the commutation device to the tool driving the lever. This control means that a time is set to switch and change the voltage. As it is shown in Fig. 2, in this implementation the tool to drive the lever is a pair of driving electromagnets. The first end of the lever has permanent magnets turned to each of the two driving electromagnets with different polarity. The switch is accompanied by the polarity change which is featured by switch frequency and electromagnetic field force applied to the permanent magnets mounted on first end of the lever. The lever has possibility of rotating when some force is applied from the drive mechanism to the first end of the lever. In such way the lever motion with different frequency is ensured.

This implementation also assumes that the lever movement frequency is changed due to change in frequency of switching polarity of the two driving magnets and the value of voltage applied.

The lever is made with possibility of setting the working element to reciprocating motion whilst the tool is driving the lever. The lever is mounted on the body housing between the first and second ends of the lever so that the lever can rotate on the housing. Such mounting can be done by means of a joint coupling or a bearing attached to the lever, provided that the bearing center is the center of the lever turn, etc. At the same time, the closer is the place where the lever is mounted on the body to the first lever end, the bigger is the magnitude of the second end of the lever.

The second end of the lever is attached to the working element. The second end of the lever has a cavity with the inserted roller and the front end of the piston is attached to the roller. The roller has possibility of moving along the lever axis by making swinging motion towards the housing and reciprocating motion towards the lever axis.

The working element is constructed with possibility of making reciprocating motion. The working element is the piston made of light and strong materials and it has the front, middle and back parts. The front part is attached to the second end of the lever as it is said above. The middle part of the piston is at least partially located in the holder block mounted on the housing. The holder block plays the role of a guide and is used to provide reciprocating motion of the piston and prevent the piston deviation whilst it is making reciprocation, which means that the holder block should ensure reciprocating movement of the piston along the axis which coincides with the holder block axis. What is more, the lever rotation surface coincides with the surface of piston making reciprocating motion, which improves efficiency of the piston reciprocating movement.

The back part of the piston has blades which can unfold when the piston is moving in the direction opposite to the expected direction of the body movement. In the working position the blades form a surface with the angle bigger than 0° and less or equal to 90° between the piston axis and the blade surface (movement without maneuvering) and ensuring maximum environment resistance force against the piston movement. When the blades fold when the piston is moving to its initial position and the minimum environment resistance force against the piston movement is ensured. The surface formed ensures repulsion from the environment at the piston working phase, which triggers the body movement from the point of repulsion.

According to the claimed solution, the blades are attached to the piston and to the first end of the rods, whilst the second end of the rods is attached through an auxiliary control lever to a coupling mounted on the piston with possibility of making reciprocating motion along the piston axis. In the mounting points it is preferably to use ball joints whic h are the most reliable and don't have a large friction coefficient. The second ends of the rods and the auxiliary control lever are attached to the second ends of the blades driving rods mounted along the piston. Each first end of the blades driving rods is attached to a respective movement intensifier. The movement intensifier may be electro mechanic or electromagnetic, and its purpose is to ensure movement of each separate blade driving rod towards the piston to set the blade in motion. In this way, when two blades are turned at different angles, the possibility of maneuvering is ensured. Each movement intensifier is mounted in a rotary holder block rigidly fixed on the housing. The movement intensifiers are attached to an asynchronous control unit attached to a movement sensor.

The second end of rods is attached to the coupling mounted on the piston with possibility to make reciprocating motion along the piston axis. The coupling can make reciprocating motion on the piston in the direction opposite to the piston movement direction, which ensures synchronized unfolding of the blades while the piston is moving in direction opposite to the body movement direction, and synchronized folding of the blades whilst the piston is moving in the same direction with the body. The unfolded blades increase surface of repulsion from the environment. The folded blades create less resistance to environment whilst the piston is moving in the direction of its initial position.

Two restrictors are mounted on the piston to restrict the coupling movement along the piston by setting the minimum and maximum angle of the blades folding and unfolding. These restrictors can move on the piston axis to reduce the magnitude of the blades unfolding on the piston back part, which allows to manage the working area of the surface formed by the blades. The larger is the surface area formed by the blades, the larger is the environment space (area), from which the piston will be repelled. Provided that the piston reciprocation movement frequency is unchanged, the larger area of the blades surface is, the bigger momentum will be received by the body directed at the body movement. In other words, the larger is the surface area formed by the blades, the higher is the speed gained by the body. The opposite is also true: reduction in the surface area formed by the blades results in proportional reduction of the body acceleration.

According to another implementation of the drive, the rods which transfer the coupling movement along the piston, are telescopic, which means that their length can change. These rods have remotely controlled starting mechanism which has possibility of managing the range of the rod extension and reduction. The driving mechanism is remotely controlled. Change in the rod length impacts the blade unfolding angle. At the angle different from 90° as to the piston axis, the blade additionally performs a function of a guide, which results in more precise maneuvering.

Another implementation is the drive with the holder block which has possibility of moving in direction perpendicular to the piston axis. This movement is possible by means of a connecting rod synchronized with the drive mechanism. For such implementation the housing should have a socket to locate freely both the holder block and the piston. Whilst the piston is moving the holder block and piston ensure synchronized with the motor movement directed at moving the piston in a special trough located on the body housing. The trough length is the same as the piston movement length. The trough has a variant width: in its part designed for the blades movement it is wider than in its part relevant to the holder block movement. Such implementation allows to reduce resistance of the environment counter flow and reduces efforts applied to move the piston towards the direction of the body movement.

According to another implementation,

moreover, the working element is constructed as a piston which has the front part, the middle part and the back part where the front part is connected to the second end of the lever, the middle part is located in a holder block and the back part has blades which are configured with possibility of unfolding whilst the piston is moving in direction opposite to the expected body movement; in the end position at least one blade forms a surface which makes an angle from zero to 90° with the piston axis, whilst piston is moving to its the initial position, the blades may fold. There are projections on the blade edges located at the angle with the blades surface and curved in direction opposite from the rods. Such projections allow to increase resistance ratio in the working phase (definitions of the neutral and working phases are given further in the text). The blades are attached to the piston and to the first end of the rods while the second end of the rods is mounted through an auxiliary control lever to the coupling mounted on the piston which can make reciprocation movement along the piston axis. It is preferable to use ball joints in the points of mounting since they are the most reliable and have a low friction ratio. The second end of the rods and the auxiliary control lever are attached to the second ends of the blades driving rods mounted along the piston. Each first end of the blades driving rods is attached to a relevant movement intensifier. The movement intensifier can be made electro- mechanic or electromagnetic and it is needed to ensure motion of each separate blades controlling rod relative to the piston to set the piston into motion. That is how the possibility of maneuvering is ensured when two blades are tilted with different angles. Each movement intensifier is mounted in a rotary holder block rigidly mounted on the housing. The movement intensifiers are attached to asynchronous control unit connected with to a motion sensor. The motion sensor can measure the motion speed, define direction and position of the piston shift and can transfer these data to the asynchronous control unit.

Besides, it is possible to use more than one drive on the body housing. At the same time the beginning of the working cycle for each motor can be shifted to ensure a smoother motion when drives are run one after another. Increased number of drives will result in a steadier motion, a lower deviation from the desirable body movement course as well as more equal distribution of the body weight between the pistons.

The body movement is performed as follows.

The motor movement operation is based on the principle of the body repulsion from environment by means of a piston which can move in direction opposite to the anticipated body movement direction in order to put the body in motion (working phase) and move back in the initial position (neutral phase) to repeat the cycle.

The system body - drive (drives) has the mass center. When the piston(s) move in the working phase along the body housing, the mass center is shifted in direction opposite to the piston(s) movement direction. When even number of drives is used, and the system is vertically oriented towards the gravity force vector, the drives operation in antiphase result in shifting the body mass center against the direction of the gravity force vector. Slowdown of the pistons movement speed results in slowdown of speed of mass center shift, which allows to have the body hang up in the target point. Movement in air environment requires applying the lifting force. At the same time movement in water environment is less demanding to such drive feature due to a difference in density of the above air and water environments.

When the body is moving vertically the lifting force can be described as the difference between the environment drag to the piston(s) in the working phase and the sum of gravity forces applied to the system 'body-drive(drives)' and resistance of the environment to the body movement. It is obvious that upon positive lifting power the vertical body movement in the environment is ensured.

Another condition for applying this implementation is the ratio between the body mass and the sum of pistons masses which move repeatedly along the body housing. To ensure effective work of the motor, the body mass should be much bigger than the sum of pistons masses. It allows to reduce deviation of mass center shift of the system body-drive and ensure more effective work of the motor.

Under these conditions, the pistons, in particular, should move along the body housing in direction to base (surface of the ground). The piston axis of each motor lines up with of the vertical axis of direction of the earth gravity vector. When one motor is in the working phase, the other motor is in the neutral one.

An essential part of this implementation is that reciprocating motion of the piston is ensured outside the body housing. Reciprocation motion of the piston is described by the working phase defined by the piston movement direction which is opposite to the expected direction of the body movement and the neutral phase which is defined by direction of the piston movement towards its initial position.

The piston has front and back parts where the piston back part has blades which unfold when the piston is moving in the working phase. In this phase the piston forms a surface in its end position with at least one blade which makes with the piston axis an angle bigger than 0° and less or equal to 90°. The blades are folded while the piston is moving in the neutral phase. In the working phase the piston has its initial position in which its speed relative to the body housing is equal to zero. Mainly the piston is a part of the drive described above. The lever gives reciprocation to the piston and the piston moves in direction opposite to the body movement expected direction. At the same time in the working phase the piston is pushed off the environment by the unfolded blades and the body housing is moved from the piston due to movement of the lever attached to the front part of the piston. When the piston is moving in the working phase, the environment provides resistance to the surface formed by the blades, which results in reducing the piston movement speed. Compensation of the piston movement reduction is made due to an increase in movement of the body which is repelled from the piston by means of the lever movement. After the piston reaches its extreme point in the working phase, at which the piston speed against the body housing is equal to 0, the lever turns the piston in the position where it was in the beginning of the working phase when its speed was equal to O against the body housing.

In the neutral phase the blades fold to reduce resistance of the environment which is moving towards the body. It is preferably to use movement of the piston in a trough of the body housing in the neutral phase to reduce resistance of environment to a greater extent.

Through adjusting the blades unfolding, the body maneuvering is ensured when the body is moving. According to another implementation, the restrictors are made with possibility of moving along the piston axis. Position of the restrictors can be changed in advance, before the drive is put in operation, or in-process when the drive is working. The preliminary adjustment of the restrictors position is done by mounting them on the piston, for example, with the aid of a wedge-shaped compactor that is extended from the compactor into the space between the compactor and the piston. When the compactor position is changed in-process, the above-mentioned wedges are made radio-controlled. The compactor position is changed based on the direction of piston movement: the wedge - shaped compactors are moved inwards the compactor, which allows the compactor to move by its own momentum, which ensures the change of its position. When reaching the required position, the wedge-shaped compactor is set between the compactor and piston. The change of position can be controlled either with the aid of a radio -signal or a signal which is transmitted by a short distance communication channel. The compactor movement can be initiated by magnetic commutators or by others like them. Change of the compactor position has a direct impact on the rod movement magnitude. At the same time the rods are formed telescopic which means that their length can change. For this the rods have remotely controlled trigger which has possibility of managing the range of the rod extension and reduction. Along with change of the compactor position, change of the rod length allows to control more precisely the range of blades unfolding, which impacts the capacity to maneuver.

According to another implementation, the blades are mounted to the piston and to the first end of rods. The second end of rods is attached through an auxiliary control lever to the coupling mounted on the piston which can make reciprocating motion along the piston axis. The auxiliary control lever is used to transfer the change in position of the blades driving rod to the rod.

On Fig. 3 is shown position of the blades surface perpendicular to the piston axis. In this condition the piston and the blades driving rods move synchronous. With such position of the blades the maximum repulsion force from the environment is provided, which ensures the maximum repulsive force when the piston is moved in direction opposite to the expected body movement direction.

On Fig. 4 is shown the moment of transition of blades driving rods shifting towards the piston axis, which results in deviation of the blades surface from orthogonal position against the piston axis when completing the working phase, which ensures the change (deviation) of the body movement direction.

On Fig. 5 is shown the blades position in the neutral phase when the piston is moving in direction towards its initial position. At the same time the blades fold reducing resistance to the contra flow of environment.

On Fig. 6 is shown how each of the first end of the blades driving rods is connected to a respective movement intensifier. The unit of asynchronous control obtains data from the movement sensor about current direction of the piston movement to define the time when the movement intensifier should be activated for each separate blade driving rod. The shock dumpers are mounted on the ends of driving rods to prevent piston blades from damage.

Environment where the piston is moving should have a minimum impact on the body in the working phase and but the same time it should have a high resistance to the piston movement in the working phase, but should be directed opposite to the piston movement and towards the expected body movement and in the neutral phase environment should offer a minimal resistance to the piston movement. In other words, the environment resistance to the piston in the working phase should be bigger than the environment resistance to the body when the piston is moving in the working phase.

The drive works as follows. The drive starts the piston drive mechanism. With this either a torque is transferred to start the flywheel, or voltage is transferred to the driving electromagnets based on an implementation of the tool to drive the lever. The lever starts to rotate making swing movement towards the point where it is attached to the body housing. The bottom part of the lever initiates the piston reciprocation in the direction opposite to the expected body movement direction. With that the blades unfold affected by the environment resistance and form a surface making an angle bigger than 0° and less or equal to 90° with the piston axis, which increases the area of resistance to the environment. The piston is repelled from the environment and the body starts moving. Then the cycle is repeated.

Below are given calculations of capacity of one motor and speed of piston to keep the mass center of 'body-piston' system immovable relatively to the earth surface in the piston working phase when the piston axis is directed vertically towards the earth and the total mass of the system is less than 130 kg.

A pair of rectangular plates is used as the blades. The plates are made of solid and light materials, for example, magnesium-base alloy, which create strong and light solid surface of total area 4 square meters. Dimensionless aerodynamic drag coefficient is taken as 2,0. Gravitation acceleration is 9,81 m/sec ² Air density is 1,3 kg m ³ . So, the required speed of piston movement and power of the drive can be calculated:

The speed of piston movement relative to the air is 16 m/sec. Power of one drive is 21 KW.

Based on this description, the operating principle of the claimed drive and how to change the drive components for analogical ones should be clear to an expert in this field.
