Abstract
Wireless Sensor Technologies will develop a passive wireless temperature sensor system for gas turbine engine applications under the referenced SBIR. Once productized, the functional and operational goals for the sensor are to 1) Measure the surface temperature of the Yttria Stabilized Zirconia Thermal Barrier Coatings (YSZ TBC’s) typically applied to turbine blades in the hot section of the gas turbine engines, 2) Measure temperature at specific locations on the surface of the combustor liner to determine both radial and circumferential temperature variations (pattern factor). Thin film passive wireless sensors will be arrayed in an annular ring around the combustor to determine pattern factor in an effort to sense the uniformity of combustion downstream from the fuel injectors, and 3) Measure heat flux across the section thickness of thermal barrier coatings by pairing the proposed wireless temperature sensor (for the surface temperature measurement of TBC’s) with a similar wireless temperature sensor being developed under another program. The combination of that sensor and the sensor being developed under this SBIR program will allow the measurement of heat flux across the TBC and open the possibility of TBC health monitoring.
