NICOTINE REPLACEMENT FOR INTERACTIVE SMOKING CESSATION

Not Available This proposal addresses the development of a novel blade clearance measurement system (CMS) for gas turbine engines. Innovations related to electronic signal conditioning, sensor and cable configuration, and signal processing improve the resolution and bandwidth by a factor of 10 compared to commercially-available systems and allow operation to 3000F. The CMS also functions as a blade vibration detection system that serves as a Non-Intrusive Stress Measurement System (NSMN). In Phase I, the feasibility will be demonstrated by designing, fabricating, and programming a developmental system and performing proof-of-concept experiments. The Phase I experiments include demonstrating the performance of the CMS at prototypical blade tip speeds and temperatures. In Phase II, a prototypical system will be built and tested in gas turbine engines.
