FIELD: machine engineering.
SUBSTANCE: plurality of measured physical parameter of the turbomachine to form a current index characteristics of the turbomachine and a plurality of indicators calculated deteriorated characteristics of turbomachine using a thermodynamic model including aging. For each indicator deteriorated characteristics suggest that degrade only one functional unit of the turbomachine. The method allows to distinguish the reduction characteristics associated with aging turbomachine from abnormal degradation.
EFFECT: increased speed and reliability of the detection of degradation of the turbomachine.
