Evaluating and testing thermographic phosphors for turbine-engine temperature measurements
Description:
A technique developed earlier for measuring the temperature of inaccessible surfaces in low-temperature rotating machines is being adapted to measure the temperature of surfaces at the higher temperatures and in the erosive environment inside operating turbine engines. The method uses the temperature dependence of the characteristic decay time of the laser-induced-fluorescence of thermographic phosphors to measure the temperature. This paper summarizes recent work in four areas: phosphor charac…
