Processing method of a multi-degree-of-freedom piezoelectric driven flapping-wing micro air vehicle and a transmission mechanism thereof

Abstract

The invention discloses a processing method of a multi-degree-of-freedom piezoelectric driven micro flapping wing aircraft and a transmission mechanism thereof. The aircraft comprises an aircraft fuselage, a transmission mechanism, two flexure hinges, two pairs of auxiliary wings, a pair of main wings, a pair of first bimorph piezoelectric actuators and a pair of second bimorph piezoelectric actuators. The transmission mechanism is fixed on the top of the aircraft fuselage; The flexure hinge is symmetrically inserted at both ends of the transmission mechanism; Two pairs of auxiliary wings areadhered to both sides of the second bimorph piezoelectric actuator respectively. The main wing is adhered to the upper left and right flexure hinges respectively. The upper end of the first bimorph piezoelectric actuator is connected with the transmission mechanism as a movable part, and the lower end is fixed on the aircraft fuselage; The upper end of the second bimorph piezoelectric actuator iscoupled to the auxiliary wing and the lower end is fixed to the fuselage. The invention has the advantages of light weight and small size, can well imitate the flight attitude of insects, realizes multi-degree-of-freedom control, and has excellent balance and stability.

Description

technical field [0001] The invention relates to a micro-flapping-wing aircraft and a micro-processing method, in particular to a multi-degree-of-freedom piezoelectric-driven micro-flapping-wing aircraft and a processing method for a transmission mechanism thereof. Background technique [0002] With the rapid development of science and technology and the continuous expansion of market demand, micro-aircraft has attracted more and more attention. In practical applications, it is expected that the aircraft can be designed as small as possible, and it is best to be very light and convenient to carry around. Therefore, it has good flexibility, and its value space is huge for its application, whether it is for military or just for civilian use. [0003] In 1992, the U.S. Defense Advanced Research Projects Agency took the lead in proposing the concept of the bionic flapping-wing aircraft, and the flapping-wing aircraft gradually entered people's field of vision. In 1997, the U.S....

AI Technical Summary

Problems solved by technology

However, according to the existing technology, it is only possible to achieve stable control when the wingspan of the aircraft is more than 10cm; it is difficult to achieve the balance of the aircraft for insect-scale aircraft, and it is also difficult for the aircraft to control the attitude angle in multi-degree-of-freedom flight.

[0005] Similarly, some domestic colleges and universities, such as Beijing University of Aeronautics and Astronautics, Northwestern Polytechnical University and Nanjing University of Aeronautics and Astronautics, have done some research on this aspect, but due to the imperfection of existing theoretical research and the lack of processing conditions Mature, but still no good performance insect-scale flapping-wing aircraft prototype reported
