Abstract

The invention belongs to the field of aero-engines, and particularly relates to an aero-engine power extraction system with an on-off function and a debugging method thereof. Comprising a high-pressure shaft power extraction module arranged on a turbofan engine system; the low-voltage shaft power extraction module is arranged on the turbofan engine system, and the low-voltage shaft power extraction module comprises a power output shaft and a clutch device, and the power output shaft is arranged at the front end of a low-voltage shaft fan and used for driving a load system; according to the clutch device, connection and disconnection of the load system and the turbofan engine system are achieved through relative movement of a built-in active friction plate and a built-in passive friction plate. According to the invention, power extraction of a larger quantity level can be realized, the operation performance of the engine is improved, the increasing requirements of airplanes are met, and the increase of the design difficulty of parts and the deterioration of the performance caused by a single power source are reduced.

Description

technical field [0001] The application belongs to the field of aero-engines, and in particular relates to an aero-engine power extraction system with an on-off function and a debugging method thereof. Background technique [0002] As the power source of the aviation platform, the aero engine not only provides the flight platform with the power required for air flight, but also provides the required electrical energy for various electrical equipment and systems on the aircraft. Since the development of aero-engines, most conventional twin-rotor turbofan engines have a high-pressure shaft that drives the central transmission unit to output power, and is connected to a generator to realize the conversion of energy from mechanical energy to electrical energy. With the development of aviation technology, airborne avionics equipment is developing towards high power and high energy consumption. At the same time, it must meet higher technical indicators such as low noise and low emi...
