Aviation aircraft with starting and launching integrated function and control method thereof

Abstract

The invention discloses an aviation aircraft with a starting and launching integrated function. The aviation aircraft comprises a starting motor, an engine and a storage battery. The starting motor is connected with a starting and launching integrated controller, the storage battery supplies power to the starting and launching integrated controller, the starting motor adopts a permanent magnet three-phase alternating current lossless motor, and the engine is provided with a power output shaft. The power output shaft is connected with a motor rotor arranged in the starting motor, a power output shaft can be driven by the starting motor to rotate, the motor rotor comprises a rotor magnetic cylinder, the rotor magnetic cylinder adopts neodymium iron boron permanent magnet magnetic steel, the starting and launching integrated controller is controlled by an MCU module, and an algorithm controlled by the MCU module adopts DTC. And a DC-DC conversion circuit is arranged in the starting and launching integrated controller. In a word, the aircraft has the advantages that a power generation function is stable, a machine body load is reduced, a starting torque is large, starting is not affected by a temperature, and the storage battery is ensured not to be short of power all the time.

Description

technical field [0001] The invention belongs to the technical field of aircraft engines, and in particular relates to an aircraft with an integrated engine function and a control method thereof. Background technique [0002] Aeroengine is a highly complex and precise thermal machinery. As the heart of an aircraft, it is not only the driving force of aircraft flight, but also an important driving force for the development of aviation industry. After more than a hundred years of development, aeroengine has developed into an extremely reliable Highly mature products, there are more and more types of engines, and their functions are becoming more and more perfect. At present, in the field of aircraft, especially small aircraft, the engine used as a power system is very important equipment. The original aero engine used only has The starter motor with starting function, these original starter motors drive the power output shaft of the generator to rotate through the reduction mec...
