Wing-deformation-based control mechanism of hummingbird-imitation flapping-wing unmanned aerial vehicle

Abstract

The invention discloses a wing-deformation-based control mechanism of a hummingbird-imitation flapping-wing unmanned aerial vehicle. The control mechanism comprises linear steering engines, a rotary steering engine, a linear steering engine base, a rotary steering engine base, wing joints, steering engine pull rods, semi-cylindrical fasteners, rotary steering engine rocker arms, wing root carbon rods, a wing joint main shaft carbon rod, a rotary steering engine control carbon rod and other parts, wherein the main body parts are obtained through a 3D printing processing mode by using resin or nylon materials, and the mass is very light; the two linear steering engines and the one rotary steering engine are utilized, so that the full-attitude control of the 3 degrees of freedom of pitch, roll and yaw is achieved; and on the basis of realizing full-attitude control, the large pitch, roll and yaw control angle is generated through the structural optimization design, so that the very important significance for controlling the attitude of a prototype in the hovering flight state is achieved, and a foundation for the subsequent design of a lightweight and compact flapping-wing prototype is provided.

Description

technical field [0001] The invention relates to a control mechanism of a bionic aircraft, which belongs to the technical field of unmanned aerial vehicles or the field of robots. Background technique [0002] In recent years, with the vigorous development of bionic research and the increasing demand for UAVs in domestic and foreign markets, research on flapping-wing unmanned aerial vehicles has attracted more and more attention. Compared with common fixed-wing and rotary-wing aircraft, the flapping-wing unmanned aerial vehicle has significant advantages such as high efficiency, light weight, strong maneuverability, and low energy consumption, and has a wide range of application prospects, especially in the military field. host. [0003] In the design of the flapping-wing unmanned aerial vehicle, the design of the control mechanism is a very important part. In the design of the control mechanism, there are mainly two control methods: the control method based on changing the...
