Ultra Low Loss RF Windo Materials

Not Available Aircraft-turbine-engine operation can greatly benefit from the development of sensors and actuators (pressure sensors, flow controllers, etc) that can withstand the gigh-temperature environment at various close-in locations. In this Phase I proposal, ISSI, in collaboration with the University of Cincinnati, will determine the feasibility of using SiC for high-timperature turbine engine fan and compressor-blade air-flow control and sensor structures. SiC is a refractory semiconductor material that has been used to fabricate robust electronic devices operating at temperatures higher than 600C. A plan will be drafted and executed for specific SiC sensor and flow-control structure and technology development during a subsequent Phase II program.
