Abstract

The invention discloses a hybrid aircraft, which comprises: aircraft fuselage; wings with high aerodynamic efficiency; high lift device; fuel engine; electric motor; battery; motor controller; switch, so that when the high-lift device is deployed, the electric motor is in the pre-position state; when the aircraft takes off or goes around, the fuel engine is started, and the electric motor is started to output the auxiliary power required for the aircraft to take off or go around; When the unit is stowed, the electric motor is turned off and only the fuel engine is driven. According to the hybrid aircraft of the present invention, a brand-new design concept is provided. It uses the electric motor to assist the aircraft, so as to reduce the demand for engine thrust when the aircraft takes off and goes around. Reduce the aircraft's index requirements for fuel engines.

Description

technical field [0001] The present invention relates to a hybrid aircraft using a fuel engine and an electric motor. Background technique [0002] Mainstream aircraft in service are powered by fuel engines, such as turbofan engines with large bypass ratios, whose overall efficiency has gradually reached its peak. In addition, the traditional fuel-powered aircraft has a greater demand for engine power during take-off and go-around, while the demand for power during cruise is much smaller. If the traditional fuel power is used, the requirements for the fuel engine are higher, which not only requires the fuel engine to provide sufficient thrust during the take-off and go-around phase, but also requires lower fuel consumption during the cruise phase. [0003] In this regard, with the optimization of the energy structure, the concept of using electric motors as power has appeared in recent years, and has been applied to small aircraft. The propulsive power of the electric motor...
