Unmanned aerial vehicle

Abstract

The invention discloses an unmanned aerial vehicle. The unmanned aerial vehicle comprises an aircraft body, flying cantilevers and propeller blades. An upper-layer oil storage cavity, a middle bufferoil cavity and a lower-layer electrical equipment cavity are arranged in the aircraft body from top to bottom, the upper-layer oil storage cavity and the middle buffer oil cavity are connected with each other, a flight control plate is installed in the lower-layer electrical equipment cavity, a methanol engine is arranged below each propeller blade, and a damping supporting mechanism is further arranged below the aircraft body; an oil pipe channel for accommodating an oil pipe and a cable channel for accommodating a cable are arranged in each flying cantilever; and oil inlet holes connected with one end of the oil pipe are arranged in the side wall of the middle buffer oil cavity, an annular oil storage groove connected with the multiple oil inlet holes is arranged in the middle buffer oilcavity, the other end of the oil pipe is connected with the methanol engine, one end of the cable is connected with the flight control plate, and the other end of the cable is connected with the methanol engine. An unmanned cruising ability can be improved, and stable oil supply and soft landing of the unmanned aerial vehicle are achieved.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle. Background technique [0002] Unmanned aircraft, referred to as "UAV", is a pilotless aircraft that uses radio remote control equipment or its own program to control the control device. Drones not only liberate people from flying machines, but also unleash the potential of aircraft because they are no longer limited by human physiology. [0003] According to the different aerodynamic layout methods, UAVs can be divided into unmanned fixed-wing, unmanned helicopters, unmanned multi-rotors, unmanned airships, unmanned paragliders and unmanned orthopters, of which the first three are the most common. And the most widely used. Unmanned fixed-wing flight has the highest efficiency, long battery life, and high cruising speed, but it needs a runway, cannot hover at a fixed point, and has the worst maneuverability; unmanned helicopters take ...

AI Technical Summary

Problems solved by technology

[0005] (1) For small methanol-powered drones, in order to provide stable oil pressure, the drone is generally equipped with a methanol pressure regulator, but when the drone encounters shaking or turning over, some drones will still appear Unstable oil supply;

[0006] (2) In addition, in order to avoid damage to the body caused by direct landing, the existing drones usually set a cushioning mechanism and wrap shockproof sleeves at the bottom of the drone, but the effect is not ideal
