AIRCRAFT GAS-TURBINE ENGINE Russian patent published in 2008 - IPC F01D15/10 

FIELD: aircraft industry.

SUBSTANCE: proposed aircraft gas-turbine engine contains compound-wound electric generator including inductor, stator and rotor arranged in inner space of engine. Rotor is connected with shaft fitted in front and rear bearings and connected with axial-flow compressor. Stator with working windings is press-fitted in thin walled cylindrical sleeve with flange. Inductor contains control winding placed on inner cylindrical part of ring magnetic circuit provided also with outer cylindrical and end face walls. Inner space accommodating electric generator is formed by inner surface of housing of guide-vane assembly and shields of front and rear supports included into axial-flow compressor. End face wall of ring magnetic circuit of inductor is secured on end face wall of rear support, and its outer cylindrical wall, or part of said wall, is arranged inside rotor holder. Flange of cylindrical sleeve is attached to end face part of ring projection made on inner surface of housing of guide-vane assembly from side of rear support.

EFFECT: provision of minimum aerodynamic resistance in internal air duct of device, reduced to minimum its outer volume and improved aerodynamic characteristics.
