Description
Technical Field
[0001] The utility model relates to the technical field of flapping-wing aircraft, in particular to a structural device of front and rear telescopic guide plates of flapping wings. Background Art
[0002] Aircraft are mainly divided into fixed-wing aircraft, rotorcraft and flapping-wing aircraft. Currently, fixed-wing aircraft and rotorcraft are relatively mature aircraft, while flapping-wing aircraft tend to be bionic aircraft. There are still many technical problems to be solved, and increasing the aerodynamic area of flapping-wing flight is one of them. At present, the flapping-wing expansion area of flapping-wing flight is mostly fixed, which makes it impossible to change the aerodynamic area of flapping-wing flight during flight, and it is impossible to obtain better flight effects. Therefore, it is urgent to develop a structural device of flapping-wing front and rear telescopic guide plates that can change the aerodynamic area of flapping-wing aircraft during flapping-wing flight. Utility Model Content

[0004] A structural device of front and rear retractable guide plates of a flapping wing comprises a guide plate arranged in the flapping wing, wherein a power device capable of controlling the guide plate to enter and exit through the rear side of the flapping wing is installed in the flapping wing, and the guide plate extends from the rear side of the flapping wing to increase the aerodynamic area of the flapping wing and improve the aerodynamic function.
[0005] Furthermore, an inlet and outlet for the guide plate to enter and exit is provided on the rear side of the flapping wing, and the power device includes a power motor, which is transmission-connected to a rotating shaft, which is rotationally connected to the flapping wing, and a gear is coaxially provided on the rotating shaft. The guide plate is located below the gear, and a horizontal rack meshing with the gear is provided on the guide plate. The rotation of the gear drives the guide plate to enter and exit from the inlet and outlet through the horizontal rack.
[0006] Advantages of the utility model: The front and rear retractable guide plates of the flapping wing of the utility model can increase the aerodynamic area during flapping wing flight, improve flapping wing aerodynamic control, and play a very important role in the process of take-off, landing, flight and gliding;
[0007] The front and rear deflectors of flapping-wing aircraft can provide assistance for flapping-wing aircraft during takeoff, landing, gliding and flight by extending and retracting the telescopic panels.
[0008] The flapping wing relies on the flapping area to improve the aerodynamic function. The application of retractable guide plates can improve the utilization of aerodynamics and reduce energy consumption.
[0009] The telescopic guide plate is driven by a motor to drive the gear to rotate forward and reverse, and then the horizontal rack is used to cooperate to achieve telescopic movement. BRIEF DESCRIPTION OF THE DRAWINGS
