A flapping plane with two degrees of freedom motion

Abstract

The invention discloses a two-degree-of-freedom flapping-wing aircraft, which comprises a frame, a motor and a gear reduction mechanism. The chute is symmetrically arranged on the side of the frame. The rotating mechanism includes a guide block, a guide rod and a spring. One end of the guide rod is fixedly connected with the guide block, and the other end is connected with the bionic wing. The semi-arc inner wall of the groove rotates and drives the bionic wing to rotate, a spring is arranged on the guide rod, and resets under the action of the spring, and the guide rod is connected with the flapping mechanism. The up and down movement of the guide block and the up and down flapping of the bionic wing form a 180° antiphase. The present invention can realize 100° flapping range and 90° rotation range, and can better simulate the motion characteristics of the periodic and large-scale fluttering of insect wings; a pair of flapping mechanisms and a pair of rotating mechanisms are used to realize the motion of two degrees of freedom, It can reduce the complicated and bulky problems of multi-link or space mechanism driving rotation.

Description

A flapping plane with two degrees of freedom motion technical field The invention belongs to the field of aircraft, and is specifically a kind of flapping plane of two-degree-of-freedom motion. Background technique [0002] MAVs have three different flight modes: fixed wing, rotary wing and flapping wing. Compared with conventional aircraft, micro type aircraft Reynolds number is very low, about 10 1 ~10 5 between. Within this Reynolds number range, natural flying objects such as insects and small Birds, none of them use fixed-wing or rotary-wing drives similar to mechanical flight to achieve flight, they all use flapping wings It can achieve autonomous flight with extremely high maneuverability and consume little energy. Micro flapping aircraft, also known as micro flapping aircraft, micro flapping aircraft, imitation insect flying robot etc. Design by imitating the movement mechanism of natural insects is one of the hotspots of current research. Micro fl...

AI Technical Summary

Problems solved by technology

The above two designs are relatively complex and the flapping wing movement range is small, and the existing one-degree-of-freedom flapping-wing mechanism is too simple, and the three-degree-of-freedom flapping-wing mechanism is too complicated and cumbersome
