Problems solved by technology

[0002] The flapping rotorcraft is a novel aircraft imitating the flight of birds. It has the advantages of vertical lift-off and hovering in the air that rotorcraft and helicopters have. Part of the lift force will cancel each other out, resulting in lower efficiency of the flapping rotorcraft rising, while the flapping rotorcraft in the prior art has poor stability of lift, resulting in lower safety, and the flapping rotorcraft in the prior art The pulling force of forward flight cannot be changed by adjusting the airfoil, resulting in poor flight flexibility
