Double-wing type miniature bionic ornithopter

Abstract

The invention relates to a double-wing type miniature bionic ornithopter, which comprises a driving mechanism, a double-flapping-wing system, a spoiler mechanism and a principal arm, wherein the driving mechanism is just connected to the front end of the main arm, the double-flapping-wing system is positioned above the principal arm, and the spoiler mechanism is connected to the rear end of the principal arm. The driving mechanism comprises a diamond rack, a miniature direct current motor, a gear reducing mechanism and two crank-link mechanisms, the double-flapping-wing system comprises two symmetrical flapping wing racks, four flapping wing installation rods, an upper layer of flapping wing and a lower layer of flapping wing, and the spoiler mechanism comprises an electromagnetic rubber, a spoiler and a swing wing. The miniature direct current motor pulls two flapping wing racks to move up and down through the gear reducing mechanism and the crank-link mechanisms, so that the bionic flapping wings can be realized. The electromagnetic rubber in the spoiler mechanism can control the swing wing to swing from side to side by changing the current direction, so that the fly direction of the ornithopter can be controlled.

Description

technical field [0001] The invention belongs to the field of miniature bionic aircraft, in particular to a biplane miniature bionic flapper. Background technique [0002] In nature, the flapping wing flight of birds or insects can achieve rapid take-off, acceleration and hovering, with high maneuverability and flexibility. According to the frequency of flapping, the flying methods of living things are mainly divided into three types: low-frequency flapping, medium-frequency flapping, and high-frequency flapping. Due to its flight performance and purpose of use, the flapping wing aircraft is becoming more and more important in the development of models, military, aviation and other industries. The research on bionic flapping-wing aircraft is mainly divided into flapping and mechanical flapping using micromechanical (MEMS) technology. The flapping wing aircraft based on MEMS technology can reduce the weight of the body and achieve a true bionic effect, but its cost is relati...

AI Technical Summary

Problems solved by technology

The flapping wing aircraft based on MEMS technology can reduce the weight of the body and achieve a real bionic effect, but its cost is relatively high and the technology is not mature enough

The traditional mechanical flapper has the advantages of low cost and mature manufacturing technology, but its structure is complex and consumes a lot of energy. Compared with the flapper processed by micromachining, its mass is often too large

The main problems of the current research on the micro-orthopter are: how to reduce the weight and volume of the body, how to increase the lift and attitude control

[0003] At present, there are some common problems in the design of the common miniature bionic flapping wing aircraft: (1) Asymmetric flapping wing movement

There are two obvious defects in this design: 1) The weight of the steering gear is too large, and the weight of the lightest miniature steering gear is more than 3g, which is not small for a miniature orthopter designed with the 20g standard Burden; 2) The sensitivity of the steering gear is low, and it is easy to cause a response delay in the steering control. When flying in complex terrain areas, this response delay is likely to cause damage to the fuselage
