title = "Surface temperature measurements from a stator vane doublet in a turbine engine afterburner flame using an ultra-bright Cr-doped GdAlO3 thermographic phosphor",
abstract = "• Successfully demonstrated temperature measurements from Cr:GAP coated Honeywell stator vane doublet in afterburner flame of the AEDC J85-GE-5 turbojet test stand located at UTSI. - Successful coating deposition onto complex stator doublet shape by EB-PVD. - Excellent emission intensity and temperature sensitivity from 25 μm thick surface coating. - Wide temperature range 550°C to 1025°C measured over range of afterburner conditions. - Engine-compatible probe design demonstrated - Integrated excitation and collection. - Thermal protection of probe. - Unintended cooling of measurement surface to be corrected in future. x • Future Plans - Cr:GAP downselected as one of two thermographic phosphors for upcoming AFRL VAATE temperature measurements of high-pressure turbine stator in Honeywell TECH7000 demonstrator engine. - Cr:GAP downselected as one of three thermographic phosphors for upcoming NASA VIPR temperature measurements of rotating blade surfaces in Pratt & Whitney F117 engine. - 2D surface temperature mapping by gated imaging underway at NASA GRC.",
