METHOD OF DIAGNOSTICS OF COMPRESSOR OF GAS-TURBINE ENGINE

摘要

FIELD: gas-turbine engines. SUBSTANCE: proposed method of diagnostics of compressor of gas-turbine engine is based on determination of wear-out degree of members of flow part of compressor. Pressure of air ahead of compressor and after it is measured at testing mode of operation of gas-turbine engine with $$$=const, degree of increase of air pressure in compressor is determined and value of relative change of degree of increase of air pressure in compressor is found in process of its operation. Value of wear-out degree of members of flow part of compressor is determined by value of relative change and by relation of wear-out degrees one judges of reserve of stability of compressor. EFFECT: increased accuracy of diagnostics of gas dynamic stability of gas-turbine engine.
