Simplified Low Drag Hydro-Acoustic Sources Navy STTR FY2005 Sol No.: Navy STTR FY2005 Topic No.: N05-T029 Topic Title: Simplified Low Drag Hydro-Acoustic Sources Proposal No.: N054-029-0167 Firm: KaZaK Composites Incorporated 10F GIll Street Woburn, Massachusetts 01801-1721 Contact: Michael McAleenan Phone: (207) 371-2568 Web Site: kazakcomposites.com Abstract: KaZaK Composites, working with Boston University, proposes to develop and demonstrate an effective mine countermeasure (MCM) towed acoustic source to support the Navy's MCM forces. Key requirements for an underwater acoustic source include an ability to mimic ship-like acoustic signatures, operation at a low frequency range (15 - 500 Hz), high acoustical power radiation, less than 400 pound hydrodynamic drag for a 7m RHIB at 15 knots, variable depth operation, autonomous launch and retrieval from USV RHIB, sufficient durability to withstand USV and foreign object impact, low maintenance costs, shock resistance, low weight and cost. The designed transducer will not impact existing MCM equipment/procedures, nor require costly ship modifications, nor jeopardize movement of the RHIB. By engaging both composites and theoretical acoustical engineers as team members, KaZaK and the Navy are insured that developing designs will consider and address all important MCM and systems requirements. In Phase I KaZaK and our team members will perform extensive design studies, theoretical calculations to predict acoustical performance, finite element analysis of critical load conditions, CFD modeling, followed by model testing of key source components to validate performance predictions. Such an analytical approach will reduce Navy risk in Phase II. Benefits: At the conclusion of a successful Phase I and II, the Navy will be in possession of a proven design for an underwater towed acoustic source. KaZaK plans to follow three parallel paths for commercialization of the transducer and the technology for its production that will be developed in this SBIR program. If Phase II is successful, a likely progression of events would include a Phase III commercial purchase of a quantity of towed transducers by the Navy, first for sea trials and later for fleet service. KAZAK will explore the permissibility of domestic and foreign commercial sales to shipping companies looking for an inexpensive mine countermeasure system for their ships, and if appropriate, seek applications with foreign Navy fleets as well.
