Simplified Low Drag Hydro-Acoustic Sources

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.
