GAS TURBINE ENGINE AND STARTER-GENERATOR FOR GAS-TURBINE ENGINE Russian patent published in 2010 - IPC F01D15/10 F02C7/27 

FIELD: machine building.

SUBSTANCE: gas-turbine engine consists of electric starter-generator, rotor of which is driven to rotation by shaft of compressor of high pressure, stator of which is mounted on intermediate carter of gas-turbine engine. The starter-generator is enclosed into a pressure tight case installed in a front compartment of the gas-turbine engine inside the intermediate carter containing oil. Compressed air is supplied into the pressure tight case of the starter-generator. The pressure tight case consists of the first elements of connection with electric cables running in structure poles of the intermediate carter. Also the first elements of connection are pressure tight and are arranged inside a chamber restricted with the case and the intermediate carter; the chamber is fed with compressed air. The starter-generator consists of an external cylinder element forming a support for the stator, of an internal cylinder element coaxial to the external cylinder element and forming the support of the rotor, and of circular covers secured on axial ends of the external cylinder element and interacting with the internal cylinder element. Bent devices for connection of stator coils with electric cables projecting outside the case in axial direction are arranged on the external cylinder element of the case.

EFFECT: facilitation of assembly and disassembly of built-in starter-generator and simplification of its connection with feeding electric cables or cables of current distribution.
