Four-wing unmanned aerial vehicle and control method thereof

Abstract

The invention discloses a four-wing unmanned aerial vehicle and belongs to the field of special aircrafts. The four-wing unmanned aerial vehicle includes a vehicle body, wings and a landing gear. The landing gear is fixedly connected to the vehicle body. The wings include front wings and back wings, wherein both the front wings and the back wings are vertically crossed with and fixedly connected to the vehicle body. Both the front wings and the back wings are respectively provided with two transverse-flow wind wheels. Each two transverse-flow wind wheels are arranged respectively at the two sides of the vehicle body. Each transverse-flow wind wheel is driven by an individual driving motor. By means of arrangement of the four transverse-flow wind wheels on the vehicle body, a lifting and pushing force of the aerial vehicle is enhanced so that a loading performance of the aerial vehicle is enhanced. By means of the individual driving motors for respectively driving the rotational speeds of the four transverse-flow wind wheels to carrying out flight control without operation of a control surface, the aerial vehicle is enhanced in maneuverability so that the aerial vehicle can adapt various complex flying environments better. The invention also discloses a control method of the four-wing unmanned aerial vehicle.

Description

technical field [0001] The invention relates to a fan-wing unmanned aerial vehicle and a control method, in particular to a four-wing unmanned aerial vehicle and a control method, belonging to the field of special aircraft. Background technique [0002] Fan-wing aircraft is a kind of wind wheel installed on the leading edge of the wing to generate propulsion, and can provide large wing lift at very low flight speeds. It has low noise, high stability, no stall, good low-speed characteristics and lift characteristics, short take-off and landing and large load capabilities. It combines many features of helicopters and traditional fixed-wing aircraft, but consumes much less fuel; it requires little or no ground for takeoff and landing; its noise is smaller than that of helicopters, and its production and use costs are lower. much lower. The wind wheel on its wing absorbs air along the front end of the entire wing, and generates lift and thrust above the wing. It does not need ...

AI Technical Summary

Problems solved by technology

[0003] Most of the existing fan-wing aircraft are designed and manufactured according to the layout of traditional fixed-wing aircraft. The weight of the aircraft is relatively large, resulting in poor load capacity of the aircraft; in the actual flight process, the maneuverability of the aircraft is weak and cannot adapt to various complex flight environments.
