Problems solved by technology

However, the aircraft only relies on the micro-motor to provide the power required for the flapping movement through a set of spur gear reducers, and the efficiency is relatively low. It cannot control the flapping speed and flapping amplitude of each wing efficiently at any time like a bird or an insect.

Abstract

The invention provides a bevel gear train flapping-wing aircraft which belongs to the technical field of mechatronics. The bevel gear train flapping-wing aircraft comprises a flapping mechanism, a main shaft and an empennage, wherein the main shaft is connected with the flapping mechanism and the empennage respectively. The bevel gear train flapping-wing aircraft can enable two wings to have different flapping frequencies and efficiently adjust the flapping relationship between the two wings during the flying process, and can be used for lowering the energy loss caused by different flapping forces of the two wings, and eliminating the influence caused by the unbalanced flapping forces on the two sides.

Description

technical field [0001] The invention relates to a device in the technical field of mechatronics, in particular to a bevel gear set flapping-wing aircraft. Background technique [0002] The flapping wing aircraft is a micro-aircraft that imitates the flight of birds or insects. It is a new type of aircraft developed in the 1990s. It has the characteristics of small size, light weight, low cost and flexible flight. The flapping frequency of the wings is small, the size of the imitation insect is small, and the flapping frequency of the wings is high. The goal of studying the flapping-wing micro-aircraft is to improve the flapping efficiency of the system and reduce the size of the flapping-wing micro-aircraft as much as possible. [0003] At present, micro air vehicles can be divided into three categories according to the flight mode: fixed wing, rotary wing and flapping wing. When the wingspan is less than 15cm, the flapping-wing flight has more advantages than fixed-wing ...
