A micro-miniature multi-wing bionic flapping wing aircraft

Abstract

The invention discloses a miniature multi-wing bionic flapping-wing aircraft, which relates to the field of micro aircraft; specifically, it includes a frame; four rocker arms; a motor; two gears a, two gears b, and one gear c; rod and four flapping wings; the motor is fixed at the center of the frame, gear c is installed on the output shaft of the motor, and meshes with two gears b at the same time, each gear b meshes with a gear a, and each gear a simultaneously connects two gears One end of the rod is hinged together, and the other end of each connecting rod is fixedly connected to a rocker arm; at the same time, the other end of each rocker arm is fixedly connected to the flapping wing; the rocker arm drives the flapping wing to achieve low-frequency reciprocating flapping, and generates Aerodynamic lift in the vertical direction. The invention uses gears and connecting rods for transmission, which is simple to manufacture and can easily obtain higher design accuracy; compared with a single pair of flapping wings, the influence between multiple flapping wings can increase the lift force, making full use of the high lift mechanism of insects, and has the advantages of higher efficiency.

Description

technical field [0001] The invention relates to the field of micro-aircraft, in particular to a miniature multi-wing bionic flapping-wing aircraft. Background technique [0002] Since the 1990s, with the continuous maturity of traditional aircraft design technology and the great progress of microelectronics technology, micro air vehicles have been proposed and developed rapidly. [0003] Due to the characteristics of small size, light weight and strong maneuverability, micro air vehicles have broad application prospects in national security and national economic construction, and are suitable for investigation, exploration and rescue assistance in complex environments. [0004] At the same time, with the continuous exploration of natural biological flight, bionic design has been more and more applied to the field of micro-aircraft, and flapping-wing micro-aircraft that imitate the flight of insects have begun to appear. [0005] Most of the mechanism designs of the existing...

Problems solved by technology

[0006] In order to solve the problem that the micro-aircraft cannot provide enough lift in a limited space, the present invention proposes a micro-miniature multi-wing bionic flapping-wing aircraft inspired by dragonflies and other multi-winged insects. Provide enough lift and control moment, can be used for investigation and rescue work in complex environments
