[0002] A flapping-wing aircraft is an aircraft that generates lift and thrust by flapping its wings to simulate the flight of birds in nature. It has advantages that cannot be matched by straight-wing aircraft, helicopters and other types of aircraft. Currently, there are many models of flapping-wing aircraft, but their main and ailerons are mostly integrated structures with unified control to assist the flight of the aircraft. However, the integrated structure results in a high energy consumption, and the function of the ailerons cannot be fully reflected.

[0003] Therefore, an aileron structure of a flapping-wing aircraft becomes a problem that needs to be solved urgently. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide an aileron structure of a flapping-wing aircraft which can save energy consumption, assist the aircraft in increasing and reducing resistance, and adjust the attitude in time.

[0005] In order to solve the above technical problems, the technical solution provided by the utility model is as follows: an aileron structure of a flapping-wing aircraft, comprising a through-type grille keel, blades, and a gear rotating shaft, wherein the blades are arranged in a grille of the through-type grille keel and are rotatably connected thereto, and the gear rotating shaft is arranged on one side of the through-type grille keel and connected to the flapping-wing aircraft;

[0006] The blades include side rotating blades and central rotating blades. The side rotating blades are rotationally connected to the sides of the grille, and the central rotating blades are arranged in the grille and rotationally connected to the side walls thereof.

[0007] Furthermore, rotatable wing edges are symmetrically provided on both sides of the through-type grille keel, and one side of the rotatable wing edge is connected with the thickness of the through-type grille keel and gradually decreases toward the other side until the upper and lower parts overlap.

[0008] Furthermore, when the central rotating blade is turned to be horizontal, it is located inside the grille, and when the side rotating blade is in an initial state, it fits with the edge of the grille to close the grille.

[0009] Compared with the prior art, the advantages of the utility model are: the through-type grille keel of the utility model and the rotatable wing edge form an aileron structure which is wide in the middle and narrow on both sides, which can effectively reduce wind resistance; the side rotating blades are combined with the center rotating blades to quickly and effectively increase wind resistance and can quickly stop in an emergency.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0017] The aileron structure of a flapping-wing aircraft of the utility model is further described in detail below in conjunction with the accompanying drawings.

[0018] Combined with Figure 1-4 , the utility model is introduced in detail.

[0019] An aileron structure of a flapping-wing aircraft comprises a through-type grille keel 1, a blade 2, and a gear rotating shaft 3. The blade 2 is arranged in a grille 6 of the through-type grille keel 1 and is rotatably connected thereto. The gear rotating shaft 3 is arranged on one side of the through-type grille keel 1 and is connected to the flapping-wing aircraft. The blade 2 is rotatably connected to the through-type grille keel 1 to facilitate opening and closing to adjust wind resistance. The gear rotating shaft 3 is arranged on one side of the through-type grille keel 1 to facilitate connection to the main wing of the flapping-wing aircraft and controlled rotation.

[0020] The blades include side rotating blades 4 and center rotating blades 5. The side rotating blades 4 are rotationally connected to the sides of the grille 6. The center rotating blades 5 are arranged in the grille 6 and rotationally connected to its side walls. The side rotating blades 4 can rotate to adjust the wind resistance and close the grille 6. The center rotating blades 5 can adjust the wind resistance and be perfectly stored.

[0021] Preferably, the middle part of the through-type grille keel 1 protrudes outward and the thickness gradually decreases towards both sides. This structure can effectively reduce wind resistance.

[0022] In one embodiment of the present application, rotatable wing edges 7 are symmetrically provided on both sides of the through-type grille keel 1. One side of the rotatable wing edge 7 is connected with the thickness of the through-type grille keel 1 and gradually decreases to the other side until the upper and lower parts overlap. The rotatable wing edge 7 makes the edge of the aileron thinner and becomes a guide plate, thereby reducing wind resistance to a greater extent. At the same time, it is rotatably connected to the through-type grille keel 1 and the angle can be adjusted as needed.

[0023] Preferably, the connection points between the side rotating blades 4 and the grilles are on the same side of each grille. This arrangement facilitates the unified control of the side rotating blades 4 and the balanced adjustment of the wind resistance.

[0024] Preferably, the side rotating blades 4 and the center rotating blades 5 rotate in the same direction, and the two blades rotate in the same direction so that their effects are the same and further enhanced, thereby avoiding mutual interference.

[0025] Preferably, the central rotating blade 5 is located inside the grille when it rotates to the horizontal position, and the side rotating blades 4 are in the initial state and fit with the edge of the grille 6 to close the grille. The central rotating blade 5 can be perfectly stored, and the side rotating blades 4 can close the grille to reduce wind resistance.

[0026] In one embodiment of the present application, the gear rotating shaft 3 includes a central shaft 8 and an outer gear shaft 9, the central shaft 8 connects the through-type grid keel 1 and the flapping-wing aircraft, the outer gear shaft 9 is sleeved outside the central shaft 8 and the gear teeth are arranged around its side wall.

[0027] The specific implementation process of the aileron structure of a flapping-wing aircraft of the utility model is as follows:

[0028] The aileron of the utility model can change and enhance the corresponding functions of the flapping-wing aircraft, and can play a very important role in the process of the flapping-wing aircraft taking off from the ground, flying in the air, and landing, which is specifically manifested as follows:

[0029] ① The structure of the flapping aileron adopts a through-type grid keel 1, the surface of which is covered with closed blades 2 (feathers). The blades 2 (feathers) are opened and closed to block the airflow and generate power;

[0030] ② Operation of flapping wing ailerons: It can assist the huge energy consumption generated by the main flapping wing during takeoff, flight and landing, and can also assist in improving flight control capabilities;

[0031] ③ The aileron is in a horizontal state during normal flight. The horizontal aileron can be driven by the gear rotating shaft 3 to change the flight attitude. When the gear rotating shaft 3 is rotated to a vertical state, a spoiler is formed to assist in short-distance landing. The positive and negative gear rotation of the main wing directly drives the horizontal flapping wing to move up and down, providing auxiliary power and improving the overall function of the aircraft. The aircraft can be folded and retracted after landing.

[0032] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
