GAS-TURBINE ENGINE COMPRESSOR Russian patent published in 2001 - IPC

Abstract RU 2176331 C1

FIELD: high-pressure compressors of gas-turbine engines. SUBSTANCE: compressor has rotor with disks mounted on splined shaft. Low-pressure discharge space located downstream of compressor communicates with axial spaces between splined radial extensions of shaft. Axial spaces between splined radial extensions of shaft communicate at inlet with flow path of compressor through disk-to-disk space. EFFECT: enhanced reliability of compressor due to cooling disk hubs. 2 cl, 4 dwg
