Unmanned air vehicle with fixed wings and control method thereof

Abstract

The invention belongs to the technical field of unmanned air vehicles and discloses an unmanned air vehicle with fixed wings. The unmanned air vehicle with the fixed wings comprises a fuselage, a control device, main airfoils and empennages, wherein the main airfoils are arranged on both sides of the fuselage and the empennages are arranged on the tail part of the fuselage. The top surfaces of theempennages gradually incline upwards from front to back. Motors are respectively arranged on the main airfoils arranged on both sides of the fuselage. The motors arranged on both sides of the fuselage are symmetrically arranged relative to the fuselage. The output end of each motor is connected with a propeller. The control device controls the acceleration or the deceleration of each motor to realize ascending, descending and turning actions of the fuselage. The invention further discloses a control method for controlling the unmanned air vehicle with the fixed wings. The control method comprises a pitch angle control step and a yaw angle control step. The symmetrical motors relative to the fuselage are arranged on both sides of the fuselage and the control device is arranged to control the rotate speed of the motors, and accordingly the thrust which is applied to the fuselage by the propellers is changed, ascending, descending and turning actions of the fuselage are realized, and themechanical structure and the control structure of the unmanned air vehicle are simplified.

Description

Technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles, and specifically relates to a fixed-wing unmanned aerial vehicle and a control method thereof. Background technique [0002] An unmanned aerial vehicle refers to an unmanned, autonomously propelled aerial vehicle that uses aerodynamic force to carry the flight through radio remote control or its own program control and can be recycled and reused. With its own advantages and characteristics, it has been widely used in many fields. In the military aspect, the main uses of unmanned aerial vehicles include ground battlefield reconnaissance, acquisition of enemy intelligence, close-range control patrols, surveillance, electronic warfare, and ground communications. In civil use, unmanned aerial vehicles are also widely used, such as aerial photography. And image transmission, patrol monitoring and target tracking, search and rescue after natural disasters, inspections of high-voltage lines...

AI Technical Summary

Problems solved by technology

[0003] However, the existing fixed-wing unmanned aerial vehicle usually adopts the method of installing multiple steering gears on the main wing and tail of the unmanned aerial vehicle to realize the lifting and turning of the unmanned aerial vehicle, and the mechanical structure and control structure are relatively complicated.
