Vertical take-off and landing fixed-wing UAV

Abstract

The invention discloses a vertical take-off and landing fixed-wing UAV, comprising a fuselage, wings, empennages and a flight controller, wherein rotor modules are symmetrically arranged in front of the wings with a centerline of the wings in a longitudinal direction as an axis, a tail rotor module is arranged between the wings and the empennages, and the rotor modules and the tail rotor module constitute a three-rotor structure; each rotor module contains a motor, blades and a motor fixing seat rotatably connecting the motor and the fuselage, each motor fixing seat comprises a servo steeringengine and a bracket fixedly connected with a rotating shaft of the servo steering engine, and each motor is positioned on the corresponding servo steering engine and pivotally connected with the rotating shaft of the servo steering engine through the corresponding bracket. The UAV has the function of vertical take-off and landing, solves the problem of taking-off and landing troubles, and can intelligently switch between a multi-rotor UAV and a fixed-wing UAV by switching a motor swing angle via the steering engine; the advantages of the multi-rotor UAV and the fixed-wing UAV are integrated.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles, and in particular relates to a vertical take-off and landing fixed-wing unmanned aerial vehicle. Background technique [0002] Multi-rotor UAVs and fixed-wing UAVs are very common in daily life, and are often used in aerial photography, ground surveying and mapping, disaster relief and investigation and other occasions. [0003] In the process of use, it is found that the flight time of multi-rotor drones is very short, generally about 15 minutes, and the flight speed is relatively slow, which is not suitable for large-scale surveys and flights. Although fixed-wing drones solve the problem of flight endurance The problem is that the time is short, but it needs to be ejected when taking off, and the UAV cannot hover at a fixed point during the mission, but can only hover. At the same time, there are strict requirements on the landing site during the landing process. , The site mu...

[0003] In the process of use, it is found that the flight time of multi-rotor drones is very short, generally about 15 minutes, and the flight speed is relatively slow, which is not suitable for large-scale surveys and flights. Although fixed-wing drones solve the problem of flight endurance The problem is that the time is short, but it needs to be ejected when taking off, and the UAV cannot hover at a fixed point during the mission, but can only hover. At the same time, there are strict requirements on the landing site during the landing process. , the site must be open and have a certain distance from the landing runway, so there are also certain problems in the practical process of fixed-wing drones
