AIRCRAFT GAS-TURBINE ENGINE Russian patent published in 2003 - IPC

FIELD: manufacture of aircraft engines. SUBSTANCE: proposed gas-turbine engine has built-in electric generator including stator and rotor which is connected with engine transmission shaft located in inner cavity of transmission. Inner cavity is formed by body of transmission supports and front cover. Electric generator is provided with compound excitation system and inductor. Stator and inductor are located in inner cavity of transmission. Inductor is mounted on front cover under stator. Stator is pressed in thin- walled cylindrical sleeve provided with flange secured to body of engine transmission supports in plane perpendicular to axis of rotation of rotor on side of front cover and with circular bore over its outer surface, thus forming stator cooling passage together with wall of said body. Rotor is mounted on drive shaft of transmission coaxially relative to stator and inductor. EFFECT: reduced overall dimensions of engine; enhanced operational reliability. 2 dwg
