Passive-torsion sweeping-type three-degree-of-freedom micro flapping wing air vehicle

Abstract

The invention relates to a passive-torsion sweeping-type three-degree-of-freedom micro flapping wing air vehicle, and belongs to a micro flapping wing air vehicle. A motor, a battery, a steering engine and a control circuit board are fixedly connected to the middle of a rack and connected through a wire, an empennage is fixedly connected to the tail of the rack and composed of a horizontal empennage and a vertical empennage, and the motor is connected with a speed reducing gear; the rack is of a rack structure which is symmetrical on the left side and the right side; a left flapping mechanismand a right flapping mechanism are the same in structure and parameter, are symmetrically arranged on the left side and the right side of the rack correspondingly, and are hinged to the rack; and a right flapping wing and a left flapping wing are the same in structure and parameter and are hinged to the right flapping mechanism and the left flapping mechanism correspondingly. The passive-torsion sweeping-type three-degree-of-freedom micro flapping wing air vehicle has the advantages that the structure is novel, the passive-torsion sweeping-type three-degree-of-freedom micro flapping wing air vehicle has the three degrees of freedom of flapping, sweeping and rotating, the movement trajectories of wingtips of the two wings are each in a spatial 8 shape and are similar to the movement modes of part of birds and flying insects in the natural world, the wings are subjected to passive sweeping and torsion, the aerodynamic performance of the air vehicle is improved, the bionic degree is high,and maneuverability is high.

Description

technical field [0001] The invention relates to a miniature flapping-wing aircraft, in particular to a passive torsion-sweeping three-degree-of-freedom miniature flapping-wing aircraft. Background technique [0002] The wing movement forms of insects or birds are very complicated when they fly, but they can be simplified into three basic movement forms: flapping up and down, twisting and sweeping back and forth, that is, insects or birds in nature have three degrees of freedom movement modes; It can only flutter up and down, that is, a single-degree-of-freedom flapping-wing aircraft, if on the basis of simple up-and-down flapping, adding the movement form of twisting or sweeping back and forth, it is a multi-degree-of-freedom flapping-wing aircraft; multi-degree-of-freedom flapping-wing aircraft Compared with single-degree-of-freedom aircraft, it undoubtedly has greater advantages in maneuverability and aerodynamic efficiency. [0003] Most of the known flapping-wing aircra...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides a passive twisting and sweeping type three-degree-of-freedom miniature flapping-wing aircraft to solve the above-mentioned two-degree-of-freedom motion form with flapping and twisting wings. The impact is relatively limited, and the limitation of the degree of freedom affects the maneuverability of the whole machine, making it difficult to complete complex tasks
