METHOD OF MONITORING GAS TURBINE UNIT HEALTH Russian patent published in 2012 - IPC G01M15/14 

FIELD: aircraft engineering.

SUBSTANCE: invention may be used in ACS of gas turbine unit incorporating with gas compressor plants (GCP) and gas turbine electric power stations (GTEPS). Proposed invention consists in that, prior to starting gas turbine unit, gas temperature in engine combustion system is registered. In starting said engine, the moment of starting fuel feed to combustion chamber manifolds is registered by operation of "shutdown valve open" limit switch. With definite time expired after opening of said valve and defined by calculations and experimenting, measured gas temperature is compared to that measured prior to starting gas turbine unit. If difference does not exceed preset value defined by calculations and experimenting, signal "Combustion chamber fails to fire" is generated and gas turbine unit emergency shutdown is performed.

EFFECT: higher quality of monitoring and reliability of operation.
