Miniature bionic flapping aircraft based on single-crank and double-rocker mechanism

Abstract

The invention discloses a miniature bionic flapping aircraft based on a single-crank and double-rocker mechanism, and belongs to the technical fields of machine design and aircrafts. The aircraft adopts a single-crank and double-rocker mechanism, wherein the single-crank and double-rocker mechanism comprises a single-crank mechanism gear, a left wing rocker, a right wing rocker, a left wing connecting rod and a right wing connecting rod; the single-crank mechanism gear is fixed on a frame and forms a rotation pair; one end of each of the left wing connecting rod and the right wing connecting rod is connected with the single-crank mechanism gear through a pin; the other ends of the left wing connecting rod and the right wing connecting rod are respectively and rotationally connected with the left wing rocker and the right wing rocker, so as to transmit power; an extending section is formed at the second end point of each of the left wing rocker and the right wing rocker; the extending section is connected with a flapping wing structure, so as to drive the flapping wing to perform flapping. The aircraft can basically eliminate asymmetry of the aircraft during flight, has a function of switching various flight attitudes, and meanwhile has the characteristics of compact structure, high flexibility, high compactness and low weight.

Description

technical field [0001] The invention belongs to the field of mechanical design and aircraft technology, and in particular relates to a micro-bionic flapping-wing aircraft based on a single-crank and double-rocker mechanism. Background technique [0002] At present, micro-bionic flapping-wing aircraft has attracted widespread attention due to its small size, efficient flight mechanism, and broad application space. Aerodynamic research results show that for micro-aircraft with a main size of less than 15cm, the flying mode of the flapping wing has a larger lift-to-drag ratio, stronger anti-interference ability and more flexible maneuverability than the flying mode of fixed wings and rotors. Therefore, micro-flapping-wing aircraft will play a more important role in fields such as military affairs and detection, and will occupy a dominant position in the development of micro-aircraft. In the current research on micro-bionic flapping-wing aircraft, most of the wings of the mecha...

AI Technical Summary

Problems solved by technology

In the current research on micro-bionic flapping-wing aircraft, most of the wings of the mechanism flutter with a single degree of freedom, and it is difficult to perform actions such as roll and yaw at the same time, and it is impossible to achieve flapping like insects or birds. Simultaneous attitude conversion, so it is difficult to realize the flying mode of insects or birds, and the dexterity performance is low
