Bionic flapping-wing air vehicle with self-adaptive attack angle

A bionic flapping-wing air vehicle with a self-adaptive attack angle belongs to the technical field of aircrafts. The bionic flapping-wing air vehicle adopts a structure that a miniature brushless direct current motor is connected with a two-stage gear speed reducer, and a flapping-wing structure is driven based on the quick return characteristic of a crank rocker; bionic flapping-wing thin-film wing plates provide good movement and control to realize excellent flight performance by simulating a bird winning flight movement structure; the miniature air vehicle is further provided with a self-adaptive attack angle control system, and the air vehicle can autonomously control and change the attack angle through a GPS and a fixed-height module, so that the purpose of fixed-height flight is achieved. Based on the self-adaptive attack angle characteristic, the bionic flapping-wing air vehicle generates enough lift force and thrust, efficient and stable flight of the bionic flapping-wing airvehicle is achieved, the
