Problems solved by technology

[0002] At present, the aircraft used in the world mainly include helicopters, fixed-wing aircraft, rotorcraft, powered parachutes, and powered delta wings. However, in recent years, a new type of aircraft has emerged, which is called multi-rotor aircraft in China. The mechanical structure is simple, easy to make, and the control performance is good. It can easily realize vertical take-off, landing, hovering and other actions, but its low load capacity and short sailing time make it impossible to carry out long-term sailing with heavy loads; it is still blank in this field of application , thus inventing a set of heavy-duty, foldable heavy-duty large-scale multi-rotor drones

Abstract

The invention relates to a cage type foldable multi-rotor heavy-duty large unmanned aerial vehicle, and belongs to the technical field of aviation. The cage type foldable multi-rotor heavy-duty largeunmanned aerial vehicle includes a cage airframe, a flight control device, a lift device and an attitude control device, four folding frames are unfolded, and a front left movable arm, a front right movable arm, a rear left movable arm and a rear right movable arm are unfolded; an engine is started, the engine drives left and right rotating shafts to rotate through a synchronous belt, and the leftrotating shaft and the right rotating shaft drive a large left propeller and a large right propeller to rotate crosswise; by increasing the rotating speed of the engine, the large left propeller andthe large right propeller speed up to produce larger lift, the unmanned aerial vehicle takes off vertically, and the flying attitude of the unmanned aerial vehicle is adjusted by adjusting the attitude control device; and during landing, the rotating speed of the engine is lowered, the unmanned aerial vehicle slowly lands vertically, and balance of the unmanned aerial vehicle is adjusted by adjusting the attitude control device. According to the cage type foldable multi-rotor heavy-duty large unmanned aerial vehicle, the airframe is made of an aluminum alloy or a titanium alloy by welding, andcan be folded to facilitate parking and transportation of the unmanned aerial vehicle; and the lift is large, stability is good, and the cage type foldable multi-rotor heavy-duty large unmanned aerial vehicle is suitable for lifting and hanging operation.
