Mixed layout unmanned aerial vehicle and control method thereof

Abstract

The invention relates to the technical field of an unmanned aerial vehicle, in particular to a mixed layout unmanned aerial vehicle, which comprises a vehicle body, fixed wings, an empennage and a propulsion motor, wherein the fixed wings are fixed at the two sides of the vehicle body; the empennage is arranged at the tail part of the vehicle body; the propulsion motor is arranged at the back part of the vehicle body; a paddle is arranged on an output shaft of the propulsion motor; the middle part of the vehicle body is provided with a strip-shaped installing hole; a four-rotor folding mechanism is arranged in the strip-shaped installing hole. Unique multi-rotor vehicle arms capable of realizing wireless one-key folding are used, so that the unmanned aerial vehicle can take off or land like a rotor aircraft; when the unmanned aerial vehicle is about to enter a fast cruise stage, the four vehicle arms can be collected back to the two sides of the vehicle body, so that the unmanned aerial vehicle can fly in a fixed wing airplane mode. The relative streamline type vehicle body conforms to the aerodynamic requirements better than the multi-rotor; higher speed and smaller wind resistance can be realized; the integral flight stability of the mixed layout unmanned aerial vehicle is improved.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a mixed layout unmanned aerial vehicle and a control method thereof. Background technique [0002] Rotor type aircraft can be divided into: helicopter and autogyro (referred to as rotorcraft) according to whether the rotor is driven. The helicopter can realize vertical take-off and landing and low-altitude hovering, and has superior maneuverability, and can realize hovering, vertical flight, inverted flight and side flight, etc. However, the helicopter has a complex structure, high vibration and noise, and a low speed limit. Compared with helicopters, gyroplanes have simple structure, low air-to-weight ratio, low cost, and higher aerodynamic efficiency. Compared with fixed-wing aircraft, gyroplanes can take off and land in short distances, and have good low-speed flight performance and are not easy to stall. In recent years, the unique advantages of rotorcraft ...

AI Technical Summary

Problems solved by technology

[0003] However, the rotorcraft has the following problems: although the rotorcraft can realize jumping or ultra-short-distance take-off through pre-rotation, and achieve ultra-short-distance landing through the efficient deceleration of the rotor, the rotorcraft cannot fly at high speed like a fixed-wing aircraf
