Multi-flapping-rotor aircraft

Abstract

The invention discloses a multi-flapping-rotor aircraft which comprises an aircraft body, supporting assemblies and flapping rotor assemblies, each flapping rotor assembly comprises four sets of flapping rotor devices, and the four sets of flapping rotor devices are symmetrically arranged on the two sides of the aircraft body in pairs through the supporting assemblies correspondingly; each flapping rotor wing device comprises a revolution main shaft, a rotating arm, an autorotation main shaft, a rotating wheel, a driving part, a rotor wing part, a pulling part, a brake part and a rotor wing frame, and the revolution main shaft, the rotating arm, the autorotation main shaft, the rotating wheel, the driving part, the rotor wing part, the pulling part, the brake part and the rotor wing frameare in linkage fit. Through the arrangement of the rotating wheel, the autorotation main shaft can also rotate in the revolution process, so that the rotor wing part is driven to rotate, and in the autorotation process, an upward lifting force is generated by utilizing the continuously rotating wing pieces, and the relatively large lifting force is provided for take-off and hovering of the aircraft.

Description

technical field [0001] The present invention relates to the technical field of aircraft, and more specifically relates to a multi-flap rotor aircraft. Background technique [0002] The flapping rotorcraft is an aircraft manufactured by imitating the flight of birds. It uses flapping wing surfaces like the wings of birds to generate lift and pulling force. At present, although many experts and scholars at home and abroad have carried out A large amount of research and experiment, but, because existing many flapping rotorcrafts can cause the lift offset that produces during rotor up and down operation process, make the development of flapping rotorcrafts still exist many technical difficulties, thus also just cause existing Flapping rotorcrafts have poor lift stability, low safety, and poor flexibility, and cannot freely change the flight direction of the aircraft. [0003] Therefore, it is an urgent problem for those skilled in the art to provide a multi-flap rotor aircraft ...
