TECHNICAL FIELD

The invention relates to an aerial mobile platform with multiple propellers which is capable of vertical take off and landing, wherein the aerial mobile platform with multiple propellers has detachable wings and adjusts the varying center of gravity of the carrier body by a guide apparatus with at least one detachable weight member.

STATE OF THE ART

Today, unmanned aerial vehicles (UAV) are used for various purposes in military areas, reconnaissance areas and aerial photography. UAVs may have a fixed-wing, or rotary wing and have various models capable of vertical take off and landing (VTOL). Models capable of vertical take off and landing specifically consist of multiple propellers so as to operate with multiple rotors. In VTOL models considered as they have a serial movement capacity, designs have been developed, which flight at high altitudes and are susceptible to serial movements. Unmanned aerial vehicles with multiple rotors are termed according to the number of rotors (For example, a Tricopter, a Quadcopter, etc.), and the unmanned aerial vehicles in the form of VTOL have vertical take off and landing capacity via their rotors and maintain their flight with their fixed wings without using the rotors. Fixed-wing unmanned aerial vehicles are unmanned aerial vehicles which have one or two rotors and flight by a lifting force created by the airspeed. Fixed-wing vehicles are launched by manpower, or by a catapult.

With the developing technology, the VTOL unmanned aerial vehicles are used in freight shipment and cargo transportation. Today, UAV systems are also developed for use in various models and processes. The VTOL UAVs with wings may sometimes become untrimmed during take off or flight, thereby reducing the efficiency of UVAs. Similar situations may be often encountered in cargo UAVs. For example, cargo loads loaded under, or on sides, of an UAV may cause UAV to become untrimmed during take off or flight, i.e. may lead to a loss in trim. Today, various trimming systems, or trimming apparatus are also developed in order to balance the center of gravity as a solution to the loss in trim. KR20150142662 relates to a method to correct weight imbalance, a device to measure weight imbalance, and a device and system to correct weight imbalance. In the invention, as an unmanned aircraft which is able to load a payload, including a payload part located at the bottom end of the unmanned aircraft, the payload may be divided into an upper part and a bottom part by a diaphragm. The payload is loaded on the upper part, ant the bottom part thereof is formed as an inverted triangle, or a gap is formed as an truncated reverse triangular pyramid shape, and a part of the gap is filled with a liquid and is occupied by the unmanned body.

BRIEF DESCRIPTION OF THE INVENTION

The object of the invention is to develop a vertical take off and landing aerial mobile platform with multiple propellers, which has detachable wings and balances the imbalance of the center of gravity in the carrier body during the flight without wings by a guide apparatus having at least one weight member.

In order to achieve said objects, the invention comprises an aerial mobile platform with multiple propellers comprising a carrier body, at least one propeller which is located on the carrier body and adjusts the vertical take off and landing by a controller, a first wing and a second wing, which extend outwardly from the free sides of the carrier body, at least one motor located on the carrier body, which is driven by the controller and is set so as to actuate the propeller at a predetermined revolution. Furthermore, the invention comprises a corresponding wing tip in which each wing is removably adapted to a guide apparatus on a free end thereof in a predetermined fast forward movement mode, which wing tip is symmetrically adjusted so as not to change the center of gravity of the carrier body, at least one weight member which balances the varying center of gravity of the carrier body such that the center of gravity on the carrier body is adjusted automatically, or manually, in a slow forward movement mode during which the wing tips are demounted. Thus, in a vertical take off and landing aerial mobile platform with multiple propellers which has multiple propellers and two wings, for example in an unmanned aerial vehicle, a weight imbalance formed when the wings are removed is balanced by guide apparatus attached in place of the removed wing tips. The guide apparatus balances the center of gravity of the platform. In addition, the guide apparatus may be in the form of awing in a predefined model thereof. A preferred embodiment of the invention is in the form of a flat aerodynamic member which is adapted to the guide apparatus from one end of the weight member. Thus, balancing the center of gravity is provided in the developed guide apparatus by the weight balancers in accordance with the physics rules and in a flat manner.

A preferred embodiment of the invention is an aerial mobile platform with multiple propellers according to any one of the preceding claims, characterized in that the carrier body comprises a tail connected at a rear end thereof. Thus, a tail structure connected to the carrier body is disclosed. A demounting process in accordance with the desired flight mode may be applied on that tail structure.

A preferred embodiment of the invention comprises at least one propeller connected on the tail so as to provide horizontal forward movement during the flight. Thus, the aerial mobile platform flights forwardly, with the propeller being demounted from the carrier body.

DETAILED DESCRIPTION OF THE INVENTION

In this detailed description, the improvement of the invention has been described without any limitation and only with reference to the examples in order to better explain the subject matter.

Figure 1 and Figure 2 are a perspective view of the aerial mobile platform with multiple propellers according to the invention. The aerial mobile platform with multiple propellers (8) according to the invention is an unmanned aerial vehicle. There is provided a carrier body (10) which constitutes the main backbone of the platform (8). A tail (11) is connected to the carrier body (10) at a rear end thereof. A propeller (16) on the tail is provided, which is located perpendicularly to the ground so as to provide forward movement mode of the platform. There is also provided a controller (12) located on the carrier body (10). The platform (8) is controlled via the controller (12) with a command/commands from a remote control (13) connected to the controller in a wireless remote communication therewith, and also an autonomous flight process may be performed. The remote control herein may, for example, be a tablet, or a computer. The propellers (16) are mounted on the propeller assembly tubes (14) extending from the free sides of the carrier body (10) so as to face the front end and rear end of the platform (8). Furthermore, these propellers (16) are mounted so as to provide the vertical take off and landing and be parallel to the ground. The platform comprises at least one motor (18) located on the carrier body (10), which is driven by the controller (12) and actuates every propeller (16) at a predetermined revolution. For example, the platform (8) of the invention comprises 5 motors (18) which are connected to 5 propellers (16) and actuates the propellers (16). Every propeller (16) comprises an operating corresponding motor (18). The platform (8) has a wing assembly guide line (20) to which each wing (24, 26) is detachably connected so as to be set to a predetermined movement mode. A guide apparatus (22) is provided, which is detachably mounted on the wing assembly guide line (20). In addition, the platform comprises a first wing (24) and a second wing (26), which extend outwardly from the free sides of the carrier body (10). Flerein, there is provided a corresponding wing tip (28) in which each wing (24, 26) is removably adapted to a guide apparatus (22) on a free end thereof in a predetermined fast forward movement mode, which wing tip is symmetrically adjusted so as not to change the center of gravity of the carrier body (10). There is provided at least one weight member (23) which balances the varying center of gravity of the carrier body (10) such that the center of gravity on the carrier body (10) is adjusted automatically, or manually, in a slow forward movement mode during which the wing tips (28) are demounted. An instantaneous loss in trim during the flight is tolerated with the guide apparatus (22) on the platform (8) for which a predetermined flight mode is activated with the guide apparatus (22) being attached. In addition, each weight member (23) adapted to the guide apparatus (22) is in the form of a flat aerodynamic member.

As an unmanned aerial vehicle technology, the platform (8) comprises weight members (23) having weight balancing feature, which may fly as a Quadcopter drone and may provide airworthiness due to the weight balancing in the wings (24, 26) attached after removing the wing tips (28) while flying in Quadcopter mode for the unmanned aerial vehicle both in VTOL (Vertical Take off and Landing) version with wings (24, 26) and multiple-rotor (a propeller shaft) (16) version. In order to solve center of gravity problem in a predetermined flight mode, the platform (8) comprises weight members (23) in the guide apparatus (22) attached in place of the removed flight wings (28), wherein the position of the weight members may be adjusted automatically, or manually. By changing the places of these members (23), for example, in the Quadcopter drone version, the center of gravity for flight is brought to the desired position, and a balanced and efficient flight is provided. Instant losses in trim during flight over the weight members may be tolerated. The guide apparatus (22) attached to the platform (8) of the invention may be on the wings (24, 26) which are suitable for a predetermined flight mode, containing weight members which are replaced by the existing wing tips (28) in order to provide an increase in flight time, for example.
