High-Temperature Turbine Clearance Measurement System Navy SBIR FY2011.2 Sol No.: Navy SBIR FY2011.2 Topic No.: N112-110 Topic Title: High-Temperature Turbine Clearance Measurement System Proposal No.: N112-110-1151 Firm: Nova Photonics, Inc. One Oak Place Princeton, New Jersey 08540-4701 Contact: Ethan Schartman Phone: (609) 279-9269 Web Site: www.novaphotonics.com Abstract: Minimization of blade tip clearance in the high pressure turbine and high pressure compressor is very important for turbine efficiency, reduction of emissions, and lower rotor inlet temperature which extends the service life of the engine. This can result in increased payload, extension of mission range capabilities and lower operating cost. Nova Photonics proposed to develop a high-temperature real-time blade tip clearance measurement system. It will be based on a compact, fiber optically coupled laser to perform laser Doppler velocimetry that will be capable of operating in a hostile environment with extreme temperature, pressure, and vibration changes. Benefits: With the successful development of the high-temperature turbine blade clearance system a reliable means to monitor turbine efficiency will be available. This could lead to improved fuel efficiency and less engine wear leading to longer service life. The commercial applications will be for military and commercial jet aircraft engines. Return
