Wing assembly, unmanned aerial vehicle and control method of wing assembly

Abstract

The invention discloses a wing assembly which comprises a first wing, a second wing, a folding mechanism and a self-adaptive adjusting mechanism, and the first wing is rotatably connected with the second wing through the folding mechanism, so that the first wing can be unfolded or folded relative to the second wing; the self-adaptive adjusting mechanism is arranged on the first wing and / or the second wing. The invention further discloses an unmanned aerial vehicle comprising the wing assembly and a control method. By arranging the folding mechanism and the self-adaptive adjusting mechanism, the attack angles of the wings can be changed in a self-adaptive mode when the aircraft flies horizontally to achieve the optimal lift force, the wings can be folded to serve as an undercarriage when the aircraft takes off and lands, and structural reuse is achieved.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a wing assembly, an unmanned aerial vehicle and a control method for the wing assembly. Background technique [0002] In recent years, unmanned aerial vehicle (UAV) has become the focus and focus of military equipment, academic research and product development in various countries around the world. According to its configuration, it can be mainly divided into rotary-wing UAVs and fixed-wing UAVs. Due to its small size, light weight, simple structure, easy control, and low cost, the quadrotor UAV has become a star aircraft for commercial applications in recent years, and has been widely used in military and civilian fields, such as anti-terrorism, anti-riot, Forest detection, environmental monitoring, power line inspection, unmanned swarms, etc. However, the quadrotor aircraft relies on adjusting the speed of 4 motors to complete the 6-DOF movement. It is a typi...

AI Technical Summary

Problems solved by technology

However, directly installing a fixed-wing wing on the quadrotor UAV will cause two problems: one is that the quadrotor UAV has a large range of angle of attack and a long period of negative angle of attack during the rapid forward maneuvering process of the quadrotor UAV. In this case, the lift generated by the additional wings will be reduced or even negative, which will affect flight safety; second, the additional wings will cause a lot of wind resistance when the quadrotor UAV maneuvers up and down quickly. , affecting the maneuvering effect
