FIELD: machine building.
SUBSTANCE: method involves measurement performed by means of one or more sensors located in compliance with combustion chamber; amplitudes of pressure fluctuations inside combustion chamber and time of duration or cycle of those fluctuations; evaluation of combustion chamber behaviour at endurance operating mode by building up Wehler curve for some material that forms combustion chamber, for the specified combustion frequency and for values of amplitude and cycle of measured pressure fluctuations; measurement of accumulated damage to combustion chamber during its operation at endurance operating mode of the turbine by means of Palmgren-Miner hypothesis; implementation of protective actions in the turbine if the measured value of accumulated damage exceeds limit value.
EFFECT: invention allows improving control reliability and optimising intervals of maintenance of combustion chamber components.
