Research Institution

The proposed low frequency 3-inch diameter transducer achieves the desired response that previously required a 6-inch diameter transducer. We will fabricate and test the optimized transducer designs with single crystal and textured ceramic drive material. A Trioid design will be used in CH1 and an LCAT design will be used in CH2. Our team will perform trade-off studies to determine the best path forward for Phase II. The trade-offs will include source level versus endurance, cost and risk. A possible outcome of the trade-off studies is a mix of textured ceramic and single crystal transducer designs.  The system will be tested with magnetics, power amplifier and signal generator, and will be driven with signal types used in actual fleet operation. During the Phase II Option, we will optimize the design, and build and test additional prototypes. The testing may include launches from Ultra’s portable launcher as well as NUWC’s launch facility.
