Flapping wing aircraft with tandem double-pair-wing structure and control method of flapping wing aircraft

Abstract

The invention relates to a flapping wing aircraft with a tandem double-pair-wing structure and a control method of the flapping wing aircraft. The flapping wing aircraft comprises an I-shaped fuselage, a first tandem wing and a second tandem wing 2; the first tandem wing and the second tandem wing correspondingly comprise two wings; four motors corresponding to the wings are installed on the I-shaped fuselage, and gears are correspondingly installed on the output shafts of the motors; the left side and the right side of the I-shaped fuselage are correspondingly provided with a rotating shaft,and two wing driving gears are rotatably connected to each rotating shaft; the wings and the wing driving gears are arranged correspondingly one by one, and the wings are connected with the correspondingly arranged wing driving gears; gears and the wing driving gears are arranged correspondingly one by one, and the gears are connected with the correspondingly arranged wing drive gears in an engaged mode; and a torsion spring is arranged between each wing drive gear and the I-shaped fuselage. According to the flapping wing aircraft, full-freedom attitude controllable flight with a true sense isachieved, two flight modes of level flight and hovering are unified, the hovering ability of the flapping wing aircraft is further improved, and the active radius of the flapping wing aircraft is increased.

Description

technical field [0001] The invention relates to the field of aviation technology, in particular to a flapping-wing aircraft with a tandem double-pair wing structure and a control method thereof. Background technique [0002] The flapping wing aircraft is an aircraft that realizes propulsion flight and attitude control of the aircraft through the aerodynamic force and aerodynamic moment generated by flapping the air. It has the advantages of small size, light weight, high flight energy conversion efficiency, and low flight noise. Advantage. Flapping-wing aircraft are generally divided into bird-like flapping airplanes and Kunming-like flapping airplanes, which usually use a rotating motor to drive a multi-stage mechanical transmission mechanism to convert rotational motion into swing motion to drive the wings to achieve propulsion flight. The bird-like flapping wing aircraft generally adopts a single pair of wings. In terms of attitude control of the aircraft, the flight att...

Problems solved by technology

[0004] The object of the present invention is to provide a flapping-wing aircraft with a tandem double-wing structure and its control method, which solves the problem of the traditional flapping-wing aircraft's difficulty in pitching in flight modes such as level flight and hovering. , roll, and yaw full-degree-of-freedom attitude control problems, realize the true full-degree-of-freedom attitude controllable flight, and unify the two flight modes of level flight and hovering, and can also improve the ability of the flapping-wing aircraft to stay in the air and Activity radius
