Bionic flapping-wing micro air vehicle capable of realizing high control moment generation based on double-wing differential motion and steering engine gravity center change

Abstract

The invention discloses a bionic flapping-wing micro air vehicle capable of realizing high control moment generation based on double-wing differential motion and steering engine gravity center changeand a control moment generation method thereof. The aircraft comprises a lift system, a transmission system, a control system and a power system. The transmission system achieves reciprocating flapping of the wings in a small space through a distributed gear reduction set gear and a crank-connecting rod combination. The control system drives the flapping wing tensioning beam to move forwards, backwards, leftwards and rightwards through the two independent steering engines to achieve effective adjustment of the flapping wing attack angle. The flapping wing tensioning beam is connected with thespherical hinge device on the base and is controlled by the rolling steering engine and pitching so that the change range of the attack angle of the flapping wing is effectively widened, and the control moment generated by the flapping wing is increased. Besides, when the bionic flapping-wing micro air vehicle performs attitude control, the steering effect is further enhanced by controlling the deflection of the gravity center of the steering engine, and the control moment generated by flapping wings is effectively improved.

Description

technical field [0001] The invention relates to the field of micro-aircraft, in particular to a bionic flapping-wing micro-aircraft that realizes high control torque generation based on biplane differential and center of gravity changes of steering gears. Background technique [0002] With the rapid development of MEMS processing, information remote sensing, computer science and other technologies, micro air vehicles have begun to change from concept to reality. MAVs have broad application prospects in military fields such as reconnaissance and surveillance, low-altitude patrols, and anti-terrorist blasting, as well as civilian fields such as mimic observation and fire disaster relief. At present, according to the principle of flight, MAVs can be roughly divided into three categories: fixed-wing MAVs, rotary-wing MAVs, and bionic flapping-wing MAVs. [0003] Micro air vehicles are small in size and low in flight speed, and their wings are in low Reynolds number flow during ...
