Lift-adjustable vector propulsion type multi-rotor unmanned plane

Abstract

The invention relates to a civilian unmanned plane technology. A lift-adjustable vector propulsion type multi-rotor unmanned 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 variable-lift adjustment structure is arranged on each plane arm. Each variable-lift adjustment structure is composed of a rotatable vane. In the state of level flight, an inclined angle is formed after the vanes rotate. The included angle between the inclination direction and the flight direction is acute angle. The lift-adjustable vector propulsion type multi-rotor unmanned plane is suitable for being powered by gasoline, lift can be adjusted, unmanned plane posture adjustment can be conducted without inclining the plane body in the state of level flight, and stability and operability are good; and the technical problems that in the 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 even can even occur are solved.

Description

technical field [0001] The present invention relates to a civil unmanned aerial vehicle technology, in particular to an adjustable lift vector propulsion type multi-rotor oil-powered unmanned aerial vehicle. 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 overcome. The tec...
