Problems solved by technology

[0002] The flapping rotorcraft is a new type of aircraft that imitates the flight of birds. It has the advantages of vertical lift and hovering in the air of both rotorcraft and helicopters. The core device of the flapping rotorcraft is the flapping rotor set on both sides of the fuselage. device, but the flapping rotor device in the prior art will cancel part of the lift force in the process of performing up and down movements, and the existing flapping rotor is in the process of flapping the air, the position of the rotor on the flapping rotor is fixed, resulting in The disturbance to the air is strong, so the efficiency of the flapping rotorcraft's ascent is low

Abstract

The invention discloses a swing sliding type flapping rotor device, which is characterized in that main shafts are arranged on two sides of a fuselage through flapping rotor wing brackets and are rotationally connected with the flapping rotor wing brackets through bearings, and the axial center lines of the main shafts are parallel to the axial center line of the fuselage; the center of the bottomof the swing arm is rotationally connected to the main shaft through a rotating shaft, and meanwhile the linear driving device is installed on the swing arm and electrically connected with the controller. Rotor types of the rotors are symmetrical biconvex wings, a center hole is formed in the center of the rotary disc, a center shaft penetrates through the center hole and is rotationally connected with the rotary disc through a bearing, meanwhile, the center shaft is connected to a linear driving device, the linear driving device drives the center shaft to slide on the swing arm in a reciprocating mode, and the swing arm swings relative to the main shaft through a rotary shaft. The invention discloses the swing sliding type flapping rotor device. The efficiency and the size of lift forcegeneration are improved.
