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 aircraft. Capable of vertical take-off and landing and hovering

The shortcoming of above-mentioned structure is: Although when utilizing fixed wing to realize fast flight, due to the existence of rotor and helicopter can't reach fast flight, each other is restricted, can't fully utilize respective maximum characteristic
