New Testing Facility and Concept for Life Prediction of TBC Turbine Engine Components

Source

A thermo-mechanical test facility is presented which enables testing of a cylindrical specimen under thermal and mechanical loading conditions which closely simulate the conditions in an aircraft engine. The principal features of the test facility are described. They include thermal shock during start-up and shut-down of an engine and cyclic loads comprising holdtimes simulating the loading conditions during a usual flight of an aircraft. For such conditions, the life of physical vapor deposit (PVD) thermal barrier coatings (TBC) should be determined. A concept for life predictions for TBCs based on some minimum test results is presented.
