GAS TURBINE ENGINE STARTING METHOD Russian patent published in 2020 - IPC F02N11/14 H02P1/50 F02C7/00 

FIELD: engine building.

SUBSTANCE: invention relates to starter-generator devices for aircraft gas turbine engines and method of their start-up and can be used in power supply systems used in aircrafts, ships, other vehicles and autonomous objects. Main electric machine is a brushless synchronous generator with a damper cage, an exciter, a sub-exciter and a rotating rectifier are located in a common housing. Anchor of the main electric machine with anchor winding 3, inductor exciter with excitation winding 5, anchor of synchronous sub-exciter with anchor winding 7 are fixed on the body. On the shaft common for three machines there fixed are the salient poles of inductor 9 of the main electric machine with excitation winding 10, unit of rotary rectifier 11, armature of synchronous exciter with winding 13 and system of permanent magnets 14 of synchronous sub-exciter.

EFFECT: implementation at the second stage of GTE start-up of synchronous operating mode of the main electric machine with damper cell as part of a three-stage synchronous generator without changing its design and complication of control devices.
