Solid State Converted Single Crystal Transducer Development for the MK 54 Torpedo Array

A program to develop transducers incorporating solid-state converted transductionmaterials for the MK 54 Torpedo is proposed. The program addresses the need for abroadband, high power transducer that can be integrated with the MK 54. The programleverages several millions of dollars of DARPA investment in a pilot manufacturingprocess for solid state converted transduction materials with properties thatapproach those of single crystal transduction materials, but which can be fabricatedat much lower cost. The Phase I program is directed towards developing a proof ofconcept transducer design for the MK 54 Torpedo and culminates with an in-water test.The test data shall be scaled to estimate the performance achievable in a full-scaledevice. The proposed program spans 6 months, with a three month program option. The proposed program shall demonstrate that transducers incorporating solid-stateconverted transduction materials can provide the performance needed to satisfy thedemanding requirements of the US Navy MK54 Torpedo program. Successful completionof this program will result in a manufacturable transducer design that provides anupgrade path to the MK54 Torpedo in the 2005 timeframe.
