SYSTEM FOR GENERATING ELECTRIC POWER FOR AN AIRCRAFT

The invention relates to a system for generating electric power (10) for an aircraft, including: a gas turbine (14) having a high-pressure shaft and outputting a stream of gas in order to actuate a free turbine (22), a polyphase permanent magnet generator (PNG 12) coupled with the gas turbine and capable of supplying a first AC voltage to supply via first conversion means a primary power supply network (30) of the aircraft, the free turbine and the permanent magnet generator being mounted on the same drive shaft (24) concentric with the high-pressure shaft of the gas turbine, a starter mountedon the high-pressure shaft capable of starting the gas turbine, the starter being a permanent magnet starter/generator (PMS/G 28) capable of supplying a second AC voltage to supply a secondary powersupply network (36) of the aircraft and accessories (38) of the gas turbine, and the first conversion means include two first AC/DC converters (32A, 32B) controlled from a management unit (34). 用于飞行器的发电系统(10)，包括：具有高压轴并输出气流以致动自
