The purpose of this project is to demonstrate the feasibility of using Acree's high temperature sensor technology on advanced propulsion materials, such as ceramic matrix composites (CMCs), at temperatures up to 2400F (1315C) and higher. Acree's approach is to use a Resistance Temperature Detector as well as an innovative passive wireless temperature sensor that have been developed and successfully tested at Acree and using Pratt & Whitney's burner rig facility. The sensors are fabricated directly on the gas turbine engine component using proprietary fabrication processes developed at Acree using proven high-temperature materials with a matching Coefficient of Thermal Expansion to that of the CMC and the Environmental Barrier Coating. A critical insulating layer made of a highly dense and nanocrystalline material is deposited as a supporting layer for the sensors in order to overcome the porosity of the EBC-CMC materials. Isothermal and thermomechanical fatigue tests will be performed to demonstrate the reliability, durability and accuracy of the advanced sensor technology.
