Bird-like flapping-wing micro air vehicle

Abstract

The invention provides a bird-like flapping-wing micro air vehicle, comprising a rack, a drive mechanism, a control mechanism, a lithium battery, a steering mechanism, a left flapping mechanism, a left flapping wing, a right flapping mechanism, a right flapping wing, an empennage and a pitching mechanism; the drive mechansim is installed on the rack; the left flapping mechanism and the right flapping mechanism are respectively installed at two sides of the rack, driven by the drive mechanism, and respectively connected with the left flapping wing and the right flapping wing, the flapping of the left flapping wing and the right flapping wing is controlled, so that the motion tracks of the tail ends of the left flapping wing and the right flapping wing are spherical 8-shaped; the steering mechanism is installed on the rack to control the left and right steering of the air vehicle. the pitching mechanism is installed on the rack to control the empennage to swing up and down; the lithium battery provides power to the air vehicle, and the control mechanism receives external signals and controls the overall flight state of the air vehicle. The air vehicle provided by the invention aims at solving the problems of complex structure, unstable flight, low flight efficiency, low bionic degree and the like of the existing flapping-wing air vehicle.

Description

technical field [0001] The invention belongs to the technical field of aircraft, in particular to a bird-like miniature flapping-wing aircraft. Background technique [0002] Birds in nature have amazing flying abilities, and their flight methods have always attracted people's research. The movement posture of the wings of birds during flight can generally be simplified as flapping up and down, chord twisting and sweeping back and forth. Studies have shown that birds have the highest flight efficiency when the trajectory of the end of the wing forms an "8" shape when flying. Aiming at the flight characteristics of birds, people have invented various flapping-wing aircrafts that imitate birds using wing flapping to provide lift and rotation. The flapping wing aircraft has great application prospects and development space in civil and military applications. However, the current common bird-like flapping-wing aircraft are generally single-degree-of-freedom flapping-wing struc...
