METHOD OF DIAGNOSTICS OF COMPRESSOR OF GAS-TURBINE ENGINE

摘要

FIELD: gas-turbine engines. SUBSTANCE: given method of diagnostics of compressor of gas-turbine engine is based on determination of degree of wear-out of members of flow part of compressor. In agreement with proposed method temperature of air ahead of compressor and temperature of gas ahead of turbine are measured in addition under testing mode of gas-turbine engine with $$$= const. Temperature of gas is reduced to standard atmospheric conditions. Value of relative change of reduced temperature of gas ahead of turbine of gas-turbine engine is found in process of its operation. Value of degree of wear-out of members of flow part of compressor is determined by gas dynamic stability. Degree of wear-out of compressor of gas-turbine engine is used to estimate stability margin of compressor. EFFECT: enhanced accuracy of diagnostics of gas dynamic stability of gas-turbine engine.
