Flapping-wing-like device capable of simultaneously generating thrust and lift force

Abstract

The invention discloses a flapping-wing-like device capable of simultaneously generating a thrust and a lift force. The device comprises a fuselage, a support assembly, two rotor wing assemblies, a driving assembly, a brake assembly, a pulling assembly, a control assembly and a take-off and landing assembly. The two rotor wing assemblies are symmetrically arranged on two sides of the fuselage; each rotary wing assembly comprises a revolution main shaft, a rotary arm, an autorotation main shaft and a rotary wing part, and through linkage cooperation of the revolution main shaft, the rotary arms, the autorotation main shaft, the rotary wing part and the driving assembly, the autorotation main shaft can also autorotate while the revolution main shaft in each rotary wing assembly drives the rotary arm and the autorotation main shaft to revolve; and continuously rotating wing pieces can generate an upward lift force, the pull assembly can provide a forward pull force or a push force for theflapping-wing-like device, the forward and upward push force and lift force are provided for take-off and landing of the flapping-wing-like device, and the technical effect of short-distance take-offand landing of the flapping-wing-like device can be achieved.

Description

technical field [0001] The invention relates to the technical field of aircraft, and more specifically relates to a flapping-wing device that simultaneously generates thrust and lift. 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 urgently needed by those skilled in the art to provid...
