Environmental tests of thermographic phosphors for turbine-engine temperature measurements
Abstract
A method that uses thermographic phosphors (TPs) for remote temperature measurements in hostile environments was developed. Based on the results of environmental tests, the potential for applying the TP method to measuring blade and vane temperatures in operating turbine engines was evaluated. Heat/water-quench tests, burner-rig tests, and a test in an experimental-engine hot section demonstrated that the TPs can be durably bonded to blade and vane surfaces, yet still exhibit usable luminescence after the test. A spin-pit test showed that it was possible to measure the temperature reliably on a heated rotating turbine disk. These tests and their results are described.
