Insect-imitating miniature ornithopter

Abstract

The invention provides an insect-imitating miniature ornithopter which comprises a first drive mechanism, a crank and rocker mechanism, a pulley mechanism and two wings. The pulley mechanism comprisesa large pulley, two small pulleys and two transmission belts, the two small pulleys are located on the two sides of the large pulley, the large pulley is connected with one small pulley through one transmission belt and connected with the other small pulley after being reversed at 180 degrees through the other transmission belt, the two small pulleys are connected with the two wings, and the wings are driven to flutter through rotation of the small pulleys. The insect-imitating miniature ornithopter has the beneficial effects that the ornithopter is simple in structure, convenient to manufacture and low in cost; the crank and rocker mechanism and the pulley mechanism are combined to achieve large-amplitude flutters of the insect-imitating miniature ornithopter, and the aerodynamic performance is good; and the insect-imitating miniature ornithopter can conduct hovering flight, wing fluttering parameters can be changed in the flight process, so that the flight attitude of the insect-imitating miniature ornithopter is changed, and hovering flight is achieved.

Description

technical field [0001] The invention relates to the field of bionic flapping-wing aircraft, in particular to an insect-imitating miniature flapping-wing aircraft. Background technique [0002] Since the concept of micro flapping wing aircraft was put forward, due to its potential broad application prospects in both military and civilian applications, micro flapping wing aircraft has become a research and development hotspot that advanced countries in the world have invested in. The development of this kind of aircraft mainly contains two aspects: an insect-like flapping-wing aircraft and a bird-imitating flapping-wing aircraft. Compared with the bird-like flapping-wing aircraft, the insect-like flapping-wing aircraft has smaller volume, lighter weight, stronger maneuverability, and can achieve hovering flight. It has better advantages in complex terrain observation, military reconnaissance and other fields. R&D advantage. [0003] Most of the existing insect-like micro fla...

AI Technical Summary

Problems solved by technology

[0003] Most of the existing insect-like micro flapping mechanisms can only flap back and forth along the horizontal plane, but the flapping amplitude is not large (generally around 100 degrees), and its flapping parameters cannot be changed
