A Thin Film Passive Wireless Temperature Sensor

This program will develop a thin film passive wireless temperature sensor that will: 1)Measure the surface temperature of the Thermal Barrier Coated (TBC) turbine blades in the hot section of the gas turbine engine 2)Measure temperature at specific locations in the flow path and on the surface of the combustor liner to determine both radial and circumferential temperature variations. Thin film passive wireless sensors will be arrayed with other like temperature sensors in an annular ring around the combustor to determine pattern factor to sense the uniformity of combustion downstream from the fuel injectors. 3)Measure heat flux through 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 by Wireless Sensor Technologies. That temperature sensor is designed to be formed directly on a superalloy blade and measure the surface temperature at that point. The combination of that sensor and the one proposed for development under this SBIR program will allow the measurement of heat flux through the TBC.
