GT11NM-EV Inner liner, influence of temperature fluctuation on thermal barrier coating (TBC)

In this mechanical integrity calculation performed the investigation of influences of the gas temperature fluctuations, their amplitude and frequency of changing around vertical axis of the inner liner and thickness of thermal barrier coating on residual displacements and life assessment of corrugated parts. Analyzed and investigated the elevation of bondcoat temperatures and a source of TBC spallation on concave and conclave surfaces of the inner liner in function of radios of corrugation.
