Experimental Noise Measurement System for Ship Sonar Design Navy STTR FY2015.A Sol No.: Navy STTR FY2015.A Topic No.: N15A-T015 Topic Title: Experimental Noise Measurement System for Ship Sonar Design Proposal No.: N15A-015-0093 Firm: Analysis, Design & Diagnostics, Inc. 317 West Forsyth St. Jacksonville, Florida 32202 Contact: Gary Donoher Phone: (904) 475-0094 Abstract: The Phase I research will demonstrate the feasibility of our concept for measuring vibration, waterborne, flow and flow induced noise with an affordable sensor which can be attached to a ship. The Phase I research will identify the types of sensors required to perform these noise measurements. The sensor configuration will be developed and will include key features such as how they will be connected, how they will be recorded, what sample rate will be used as well as how they will be clocked. Hydrodynamic modeling will also be performed, and this will support the design of the fairing which will be built during the Phase II effort. The team will also begin the development of the algorithms for the noise analysis software. In summary, the Phase I research will lay the foundation for developing a Phase II prototype sensor and hull mount faring which will be demonstrated during the Phase II effort. Benefits: The anticipated results of this STTR program is the development of an affordable, self-powered sensor which can be attached to the exterior of a ship to perform measurements of vibration, waterborne, flow and flow induced noise at various speed regimes. This sensor could be used by the Navy, Coast Guard, ship designers, ship builders as well as the Oil and Gas Industry. Return
