A flapping-wing aircraft with tandem double-wing structure and its control method

Abstract

The invention relates to a flapping-wing aircraft with a tandem double-wing structure and a control method thereof. The flapping wing aircraft comprises an I-shaped fuselage, a tandem wing one and a tandem wing two. Both the tandem wing 1 and the tandem wing 2 include two wings. Four motors corresponding to the wings one by one are installed on the I-shaped fuselage, and a gear is installed on the output shaft of each motor. The left and right sides of the I-shaped fuselage are respectively provided with a rotating shaft, and each rotating shaft is connected with two wing drive gears in rotation. The wings are arranged in one-to-one correspondence with the wing driving gears, and the wings are connected with the correspondingly arranged wing driving gears. The gears are provided in one-to-one correspondence with the wing drive gears, and the gears are meshed with the corresponding wing drive gears. A torsion spring is arranged between each wing drive gear and the I-shaped fuselage. The invention realizes the attitude controllable flight with full degrees of freedom in the true sense, and unifies the two flight modes of level flight and hovering, and can also improve the hovering ability and activity radius of the flapping-wing aircraft.

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
