Bionic flapping wing air vehicle

Abstract

The invention relates to a bionic flapping wing air vehicle. The problem that an existing bionic aircraft is inconvenient to steer and adjust is solved. The air vehicle comprises an air vehicle body, wing bodies are movably arranged on the two sides of the air vehicle body respectively, the wing bodies are connected with wing flapping driving mechanisms arranged in the air vehicle body, and a flapping amplitude control mechanism capable of controlling the flapping amplitude of any wing body is arranged in the air vehicle body. And wing rotation driving mechanisms capable of enabling the wing bodies to circumferentially swing relative to the air vehicle body are respectively arranged between the air vehicle body and the wing bodies. The air vehicle has the advantages that a lifting driving motor drives a connecting rod to transmit and drive the wings to flap up and down, the stability is high, the flying posture of birds can be simulated, the distance between the wing rotating mounting shaft and the rotating shaft can be changed, the wing flapping amplitude is controlled by changing the distance, and thus the steering of the air vehicle is better controlled; the wing body is of a split structure, the flight resistance is small, and the bionic effect is good.

Description

technical field [0001] The invention belongs to the technical field of aircraft, in particular to a bionic flapping-wing aircraft. Background technique [0002] With the development of aircraft technology, the research on bionic aircraft has become a frontier topic in the field of aircraft research. For example, the bionic flapping-wing aircraft can simulate the flight of birds and dragonflies in nature, and has a certain flight efficiency. The hovering performance, wind resistance, and maneuverability are also superior to those of multi-rotors and fixed wings. A disruptive technology and a hot direction, with broad application prospects. [0003] The existing bionic flapping wing aircraft is mainly realized by the flapping of two wings. Due to the inconvenient adjustment of the flapping amplitude of the wings, this driving method has many shortcomings, such as poor stability, not flexible enough to fly, and unable to better control the aircraft. Steering, bionic effect is...

Problems solved by technology

[0005] The above-mentioned scheme solves the problem of inconvenient steering control of the existing bionic aircraft to a certain extent, but there are still problems in this scheme: the adjustment of the flapping range of the wings is inconvenient, not flexible enough, the steering control accuracy of the aircraft is poor, and the bionic effect is not good.
