Gasoline-electric hybrid power matching method and system for a rotary wing aircraft

Abstract

A fuel-electric hybrid matching method and power system for a rotary wing aircraft, which is characterized by using a combination of a petrol engine and an electric motor as the power system, selecting an oil-powered engine with economical fuel consumption and power that meets the power required by the aircraft during the cruise phase, and the motor power is The difference between the maximum power required by the aircraft during vertical takeoff and landing and the maximum power of the oil-powered engine. The invention not only ensures that the maximum output power of the power system meets the vertical take-off and landing requirements of the aircraft, but also ensures that the oil-driven engine can work in a high-efficiency and low-power consumption state during the fixed-wing cruise phase, thereby improving flight efficiency and engine working conditions. , which can improve the engine working life.

Description

technical field

[0001] The invention relates to an unmanned aerial vehicle technology, in particular to a power matching technology for a medium-to-large unmanned aircraft, in particular to an oil-electric hybrid power matching method and system for a rotary wing aircraft. Background technique

[0002] Rotary wing aircraft is a new type of unmanned aircraft that has both the vertical take-off and landing performance of a helicopter and the high-speed cruise performance of a fixed-wing aircraft. The patent number is ZL201110213680.1, and the Chinese patent titled "A Rotary Wing Aircraft with Variable Flight Mode" is a typical model. The aircraft has a three-plane aerodynamic layout. Among them, in the helicopter flight mode, the main wing can rotate as a rotor to provide the required pulling force for the aircraft. At the same time, when the aircraft has a certain flight speed, it can be locked as a fixed wing to achieve high-efficiency fixed-wing flight. Therefore, during ...
