METHOD OF DIAGNOSTICS OF GAS-TURBINE ENGINE COMPRESSOR Russian patent published in 1998 - IPC

Abstract RU 2118808 C1

FIELD: checking of mechanical condition of gas-turbine engines. SUBSTANCE: air pressure is measured additionally upstream and downstream of compressor in check mode of operation n_тк.red=const, and degree of air pressure rise in compressor is determined. Then value of relative variation of degree of air pressure rise in compressor is measured in process of operation. Obtained value is used to find critical (as to gas-dynamic stability) value of degree of wear of compressor flow-through part elements. Reservoir of compressor stability of gas-turbine engine is judged by relation of degrees of wear. EFFECT: enhanced checking. 2 dwg
