In collaboration with Northrop Grumman Corporation, this project will develop an optical fiber-based automated hypergolic leak detection network to gain Navy s approval for sea-basing the KEI System. Building on the Phase I successes, indicators for optically sensing monomethylhydrazine (MMH) and nitrogen tetroxide (NTO) would be packaged as a thin film for deployment within the kill vehicle (KV). Battery replacement or servicing will not be needed once the sensor is installed inside the KV. A plurality of sensors would be networked for monitoring multiple required locations. During Phase II, the prototype would be engineered and its performances would be characterized to ensure compliance with KEI requirements with respect to parameters such as size, weight, sensitivity, response time, lack of false alarm, cross-sensitivity, temperature and humidity range, accuracy, reproducibility, measurement precision, operational life, and compatibility with the shipboard Command and Control System. At the end of Phase II, InnoSense LLC will deliver the prototype with a form factor compatible with the KEI Program for detecting the vapors of MMH and NTO at or below limits set by the regulatory agencies. Strategic partnership has been arranged for Phase III follow-on funding, and for manufacturing the sensor system in Phase III.
