End-to-end Naval Asset Damage Detection System Navy STTR FY2010.A Sol No.: Navy STTR FY2010.A Topic No.: N10A-T042 Topic Title: End-to-end Naval Asset Damage Detection System Proposal No.: N10A-042-0486 Firm: Intelligent Fiber Optic Systems Corporation 2363 Calle Del Mundo Santa Clara, California 95054-1008 Contact: Richard Black Phone: (408) 565-9000 Web Site: www.ifos.com Abstract: IFOS will demonstrate the feasibility of a minimalistic, yet powerful, distributed network of piezoelectric actuators and ultrasonic wave detecting fiber optic Bragg grating (FBG) sensors interrogated by a high frequency parallel processing FBG interrogator together with innovative mathematical and computational algorithms to process, store and visualize (via damage index maps) massive amounts of data generated from said system to enable quantitative structural health monitoring of Naval assets (ships and aircraft). The goal is development of a complete and detailed assessment of the material or structural condition well before any visible signs of deterioration develop by using a permanently installed network of FBG sensors and actuators and interrogating them only during scheduled stops or during scheduled maintenance intervals. The initial focus will be on material state accuracy rather than computational speed. In Phase I, IFOS will develop a lab bench prototype material state awareness distributed network of sensors and actuators. In Phase II, IFOS will scale up the system to enable interrogation of structures with much greater size and with much more diverse structural details such as structural ribs, stiffeners and bulkheads as well as complex composite construction such as sandwich core or rib stiffened structures. Benefits: The IFOS fiber optic damage detection system is expected to find application in many DoD platforms (such as destroyers, cruiser, amphibious ships, submarines, fighter, patrol and transport aircraft) which have key structural components (e.g., pressurized bulkheads, rudders, propellers, superstructures and wing attachment point) that require strain or loads monitoring. Installation of such a system will provide safety while allowing maintenance at longer time intervals or only when the system indicates that it is required. That will translate to considerable cost reduction. IFOS, in collaboration with the Navy monitoring team, will seek a potential military application and/or demonstration during Phase III. Return
