Fat Line Towed Array Straightening System Navy SBIR FY2012.1 Sol No.: Navy SBIR FY2012.1 Topic No.: N121-074 Topic Title: Fat Line Towed Array Straightening System Proposal No.: N121-074-0538 Firm: TIAX LLC 35 Hartwell Avenue Lexington, Massachusetts 02421-3102 Contact: Mo Rajaee Phone: (781) 879-1257 Web Site: http://www.TIAXLLC.com Abstract: The Navy relies on positioning, detection, and guidance data provided by Fat Line towed arrays. This information provides safety from potential threats and mission capability. The accuracy of this data depends on the array's being straight and not drooping; these conditions are readily met at high speeds but not at low speeds. To maintain Fat Line array capabilities at low tow speeds and in shallow water, where droop could lead to array damage by hitting the marine floor, TIAX proposes to develop a Fat Line array correction system which reduces front to back droop through an engineered lift producing concept, and minimizes off-axis drift by employing stabilizing measures built into the concept. Three dimensional modeling, preliminary proof-of-concept demonstration, and stability analysis of TIAX's lift producing concept will determine feasibility of TIAX's solution to provide sufficient lift and straightening to meet the Navy's needs at low tow speeds. Benefits: TIAX's solution is a passive solution that shall not impede high speed towing stability, and is transferable between Fat Line towed arrays of different submarines. The success of the TIAX system for reducing front to back droop and off-axis drift of a Fat Line towed array will contribute to enhancing Naval submarine safety and mission capability by allowing the array's sensors to provide crew members with more accurate data. This benefit extends beyond Naval use since towed arrays are also used in the commercial seismic geophysical industry. Similar data enhancements will be provided to these industries based on the success and deployment of our device. Return
