Disc-shaped manned four-rotor aircraft

Abstract

The invention relates to an aircraft and in particular relates to a disc-shaped manned four-rotor aircraft which is strong in cruising ability, good in operability and stability, safe, reliable, and attractive in appearance. According to the technical scheme adopted by the invention, an engine compartment is arranged on the bottom of a body, a flight compartment is arranged on the top of the body, an undercarriage is arranged at the bottom of the engine compartment, a split-flow transmission gearbox is arranged in the center of the body, the split-flow transmission gearbox is connected with a power transmission gearbox; the power transmission gearbox is connected with an engine through a clutch; the engine is mounted at the bottom of the body; steel tube beams are arranged at four output ends of the transmission gearbox; rotor gearboxes are arranged on the end parts of the steel tube beams; the split-flow transmission gearbox is connected with the rotor gearboxes through transmission shafts; the transmission shafts are positioned inside the steel tube beams; rotors are mounted on output shafts of the rotor gearboxes. The disc-shaped manned four-rotor aircraft is widely applied to various four-rotor aircrafts.

Description

Technical field [0001] The invention relates to an aircraft, in particular to a dish-shaped manned quadrotor aircraft. Background technique [0002] At present, the traditional helicopter is a single-rotor with a tail rotor layout, relying on the rotation of the main rotor to provide lift, and the high-speed rotation of the tail rotor produces a lateral push-pull force to overcome the anti-torque generated by the main rotor. This layout has a simple structure and mature technology. It can be flexibly used to manufacture helicopters of various specifications, and the operation is relatively simple. However, the tail beam causes a large parking area, the load-bearing tail beam and the long-distance tail rotor drive shaft system are easily damaged, the collision risk is high, the hovering performance is unstable, the tail rotor is easily damaged by foreign objects, causing major accidents, and the tail rotor needs to be consumed. About 15% of engine power. [0003] In addition to si...

Problems solved by technology

Due to the electric drive mode, the horsepower and endurance time of the aircraft are greatly restricted, and it is still difficult to be practically promoted.
