FIELD: engines and pumps.
SUBSTANCE: proposed method consists in measuring main parameters describing engine operation, generating go-out sign, defining derivatives of rotor rpm, pressure downstream of compressor, and combustion product temperature. Obtained magnitudes are compared with settings. If said derivatives exceed said settings, combustion chamber go-out sign is generated. Values of settings are defined by transition processes in engine parameters in combustion chamber go-out.
EFFECT: higher reliability of gas turbine operation thanks to adequate diagnostics.
