A bionic butterfly flapping wing aircraft and its pull-wire steering mechanism

Abstract

The invention discloses a bionic butterfly flapping wing aircraft and its wire-drawn steering mechanism. The steering mechanism includes a motor, a wire wheel, a wire wheel gear, a potentiometer gear, a potentiometer, a control module and a power supply, and the control module is connected to the motor and the potentiometer. The rotating shaft of the motor is fixedly connected with the wire wheel, the wire wheel is fixedly connected coaxially with the wire wheel gear, the wire wheel gear meshes with the potentiometer gear, and the potentiometer gear is fixedly connected with the rotating shaft of the potentiometer; the wire wheel gear is provided with two One wire slot and two traction lines, one end of one traction line is fixed in one wire slot and the other end is fixed at the tip of the front wing of one side of the bionic butterfly flapping wing aircraft, and one end of the other traction line is fixed on the other and the other end is fixed at the tip of the forewing on the other side of the bionic butterfly flapping wing aircraft, and the winding directions of the two traction wires in the two wire slots are opposite. The invention has the advantages of simple structure, light weight, easy manipulation, good control effect and suitable for weight sensitivity.

Description

technical field [0001] The invention relates to the technical field of flapping-wing aircraft, in particular to a bionic butterfly flapping-wing aircraft and a cable-type steering mechanism thereof. Background technique [0002] The flapping-wing aircraft is a new type of aircraft that imitates the flight of birds or insects. Compared with fixed-wing and rotary-wing aircraft, the flapping-wing aircraft has higher efficiency and better flexibility. The bionic shape makes it better concealed. And less noise, so it has a wide range of uses. The bionic butterfly flapping wing aircraft refers to a flapping wing aircraft that imitates the shape and flight mode of a butterfly. It is composed of a driving mechanism and a steering mechanism. Most of the driving mechanisms of the existing bionic butterfly flapping wing aircraft are driven by motors, and the two wings flutter synchronously. Lift and thrust are generated, and the steering is usually achieved by swinging the tail instal...

The bionic butterfly flapping wing aircraft refers to a flapping wing aircraft that imitates the shape and flight mode of a butterfly. It is composed of a driving mechanism and a steering mechanism. Most of the driving mechanisms of the existing bionic butterfly flapping wing aircraft are driven by motors, and the two wings flutter synchronously. Lift and thrust are generated, and the steering is usually achieved by swinging the tail installed at the tail of the aircraft from side to side. This steering method increases the weight and reduces the performance of the aircraft, and because the flight speed of the bionic butterfly flapping wing aircraft is slow, it is realized by changing the aerodynamics of the tail The way of steering is poor, and the turning radius is large

In addition, the steering method of adding the tail sacrifices the bionicity of the bionic butterfly flapping wing aircraft
