Embodiment

[0024] Such as figure 1 and 2 As shown, an oil-powered multi-rotor UAV with a variable lift structure includes a fuselage 10, and a landing gear 11 is fixed below the fuselage 10. The landing gear protects the safety of the entire fuselage when the UAV lands. Four fuselage arms 9 are connected to the fuselage, and the fuselage arms 9 are evenly connected to the fuselage 10 . The machine arm 9 is used to support the fuel engine 2 and the propeller 1 on it. On machine arm, be fixed with variable lift structure 3 simultaneously. The variable lift structure 3 is a symmetrical circular structure, the propeller 1 is located at the center of the variable lift structure, and the propeller 1 and the fuel engine 2 are both located above the variable lift structure 3 . A fuel engine 2 is connected below the propeller 1, and the fuel engine 2 drives the propeller 1 to run at a constant speed, and the lift force provided can quickly form the lift force required by different working cond...

Abstract

The invention relates to a civilian unmanned plane technology. Provided is a lift-variable structure gasoline-powered multi-rotor unmanned plane. The plane comprises a plane body. A plurality of plane arms are connected to the plane body. A propeller is connected to each plane arm. A lift-variable structure is arranged on each plane arm. Each lift-variable structure is of symmetrical frame structure and is composed of rotatable vanes. Two vanes in symmetrical positions are opposite in inclination direction and uniform in inclined angle size. According to the unmanned plane that is suitable for being powered by gasoline, lift can be adjusted when gasoline power is kept in uniform output power, and stability and operability are good; the problems that in prior art, an unmanned plane powered by gasoline is poor in power output stability, complicated in operation, and high in the engine vibration, and a sensor is prone to being damaged, the service life of an engine is shortened due to frequent speed regulating, and flameout can even occur are solved.

Description

technical field [0001] The present invention relates to a civil unmanned aerial vehicle technology, in particular to an efficient and rapid multi-rotor oil-powered unmanned aerial vehicle with variable lift structure. Background technique [0002] The multi-rotor UAV has simple take-off and landing requirements, low hovering speed, low requirements for the use environment, and is very flexible. As multi-rotor drones enter the civilian field, they are widely used in aerial photography, plant protection, surveying and mapping, emergency rescue and other fields. At this stage, lithium battery-powered multi-rotor drones mainly rely on the electronic speed controller (ESC) as a signal receiver to control the propeller speed, and change the propeller speed requirements according to different signal requirements. At this stage, multi-rotor UAVs mostly use lithium batteries as power. However, the endurance time of multi-rotor UAVs in this situation is a difficult problem to overcom...
