Problems solved by technology

However, it is difficult for quadrotors to realize manned flight. The main reason is the battery bottleneck. To realize manned flight, a large motor must be used, which consumes a lot of electric energy.
High-voltage, large-capacity batteries lead to overweight batteries, which eventually lead to short flight times, making it difficult to realize manned flights, let alone larger multi-rotor aircraft

Abstract

The invention relates to a multi-rotor aircraft composed of a fuel engine and a motor. The aircraft comprises an electronic speed regulator, a flight control system, the fuel engine, the motor, a battery pack, a fuselage composed of multiple crankshafts, and multiple propellers, which can be divided into first propellers driven by the fuel engine and second propellers driven by the motor. The multiple first propellers provide the main lifting force of the whole aircraft, while the multiple second propellers are responsible for the balance, direction and a small part of the lifting force of the whole aircraft. Thus, most of the lifting force of the invention is provided by the fuel engine, and a small part of the lifting force, balance control, directional control, and height control are provided by the motor. Perfectly realizing fuel-electric hybrid, the aircraft of the invention is endowed with the maneuverability and flexibility of pure electric aircrafts as well as the large load capacity of fuel engines.

Description

technical field [0001] The invention relates to an aircraft, in particular to a multi-rotor fuel-engine-motor hybrid manned aircraft. Background technique [0002] At present, the aircraft used in the world mainly include helicopters, fixed-wing aircraft, rotor aircraft, powered parachute, powered delta wing flight, etc. However, in recent years, a new type of aircraft has appeared in the aviation model industry, which is called quadrotor in China. Aircraft or quadcopter, this kind of aircraft will have very good maneuverability and flexibility, and can easily realize vertical take-off, landing and hovering. [0003] The four-rotor aircraft is composed of four main components: batteries, electric motors, electronic governors, and flight controllers. For the most common quadrotor aircraft, the number of electric motors and electronic governors is four, and the motors are installed at the four corners of the aircraft. Above, propellers are installed on each motor, two pairs o...
