Low-Profile, Broadband, Shear-Mode SONAR Transducer for Deep Submergence Applications Navy SBIR FY2014.1 Sol No.: Navy SBIR FY2014.1 Topic No.: N141-066 Topic Title: Low-Profile, Broadband, Shear-Mode SONAR Transducer for Deep Submergence Applications Proposal No.: N141-066-0131 Firm: BTech Acoustics LLC 17 Surrey Rd. Barrington, Rhode Island 02806 Contact: Corey Bachand Phone: (401) 261-9318 Web Site: www.BTechAcoustics.com Abstract: BTech proposes the design and development of a low-profile, broadband, shear-mode piezocrystal acoustic transducer for deep submergence applications. The Phase I effort considers evaluation of design variants of shear mode transducers with increased pressure operation/tolerance and tradeoffs associated with the same. Design feasibility is supported with calculations of expected performance and where possible, proof-of-principle experimentation. Benefits: Compact, light-weight, broad-band shear mode transducer may find applications in civilian underwater applications, such as UUV and tethered ROV guidance, sea floor exploration/profiling, sea floor module mining, oil platform inspection/repair.
