Embodiment Construction

[0025] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0026] Such as Figure 1 to Figure 4 As shown, the present invention provides an unmanned aerial vehicle, which can improve the endurance of the unmanned vehicle, and realize stable fuel supply and soft landing for the unmanned aerial vehicle. specific:

[0027] The unmanned aerial vehicle comprises a body 1, a plurality of flying cantilevers 2 installed in a ring array on the side wall of the body 1, and a propeller blade 3 arranged at the far end of the flying cantilever 2. The number of flying booms 2 in this embodiment is four.

[0028] The buoyancy generated by the rotation of propeller blade 3 makes the drone take off. The connecting part of the flying cantilever 2 and the body 1 is provided with triangular ribs 19 to improve the firmness...

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 ...
