Surface Temperature Measurements from a Stator Vane Doublet in a Turbine Engine Afterburner Flame Using a YAG:Tm Thermographic Phosphor - (PPT)

摘要

Successfully demonstrated temperature measurements in lab environment for both blue and UV emission band decays from YAG :Tm. Successfully demonstrated temperature measurements (static& dynamic) up to 1300°C from YAG:Tm-coated Honeywell stator vane doublet in afterburner flame of UTSI J85-GE-5 turbojet test stand using blue YAG:Tm emission band decay. Redesign of engine probe optics will allow implementation of UV YAG:Tm emission band decay for superior rejection of background reflected combustion radiation.
