Bionic flapping wing air vehicle

Abstract

The invention provides a novel bird-like flapping wing air vehicle. The novel bird-like flapping wing air vehicle comprises a vehicle body, an empennage and flapping wings, wherein the empennage is connected to the rear of the vehicle body, and the flapping wings are arranged on the two sides of the vehicle body. The flapping wings comprise inner section flapping wings and outer section flapping wings, the inner section flapping wings and the outer section flapping wings are composed of internal flapping frameworks and external skins. The inner section flapping wing framework and the outer section flapping wing framework are hinged through connectors. A motor is arranged inside the vehicle body and connected with a transmission mechanism through a reducing gear set, wherein the transmission mechanism enables the inner section flapping wings and the outer section flapping wings on the two sides of the vehicle body to coordinately move. The two sections of flapping wings are adopted, compared with a single-freedom-degree flapping wing air vehicle, the novel bird-like flapping wing air vehicle is more similar to large birds in the appearance and the flight mechanism, and the novel bird-like flapping wing air vehicle is simple in structure, high in efficiency, light in weight, and high in bearing capacity.

Description

technical field [0001] The invention relates to the field of bionic aircraft, in particular to a bionic flapping-wing aircraft. Background technique [0002] A flapper is an aircraft that imitates a bird to generate lift and forward force through the active movement of its wings, also known as a flapper. Its characteristics are: [0003] 1. Active movement of the wings. [0004] 2. Relying on the reaction force of the wing flapping the air as the lift and forward force. [0005] 3. Maneuver flight by changing the position of the wing and tail. [0006] The human dream of flying started with a flapping-wing aircraft and was initially realized with a fixed wing. A careful study of the flapping flight movements of large birds shows that although their flapping movements are varied, in normal level flight, a cycle of wing flapping can be roughly divided into down flap and up flap stages: [0007] 1. The lower flutter stage is the main stage of flutter and lasts for ...

AI Technical Summary

Problems solved by technology

[0010] In order to solve the shortcomings of the existing single-degree-of-freedom flapping-wing aircraft such as low efficiency, high consumption, and small carrying capacity, the present invention designs a novel bionic flapping-wing aircraft, which not only makes up for the shortcomings of the single-degree-of-freedom flapping-wing aircraft, but also In terms of shape and flight mechanism, it is closer to the flight of large birds
