A bird-like miniature flapping-wing aircraft

Abstract

A bird-like miniature flapping wing aircraft, comprising a frame, a drive mechanism, a control mechanism, a lithium battery, a steering mechanism, a left flapping mechanism, a left flapping wing, a right flapping wing, a right flapping wing, an empennage and a pitching mechanism; The driving mechanism is installed on the frame, and the left flapping mechanism and the right flapping mechanism are respectively installed on both sides of the frame, driven by the driving mechanism, and connected with the left flapping wing and the right flapping wing respectively, and the control unit The left flapping wing and the right flapping wing flutter and make the end motion tracks of the left flapping wing and the right flapping wing all be in the shape of a spherical "8"; the steering mechanism is installed on the frame to control the left and right steering of the aircraft; The pitch mechanism is installed on the frame and controls the tail to swing up and down; the lithium battery provides power for the aircraft, and the control mechanism receives external signals and controls the overall flight state of the aircraft. The invention solves the problems of complex structure, unstable flight, low flight efficiency and low bionic degree of the current flapping-wing aircraft.

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...
