Abstract
NanoSonic has developed a cost effective, high performance Morph-on-Demand Towed Array Outer Hosewall that can temporarily and repeatedly change its shape to significantly reduce turn induced strum vibrations. Our approach may result in significant reductions in cross-flow angles up to 30 degrees to enable unsurpassed long range target detection. The low density (0.94 g/cc), rugged, Shape Memory-Metal Rubber (SM-MR) outer hosewall was designed to house a TB-29A acoustic module for use with an OA-9070B SSN handling system. Our high performance matrix resins and longitudinal reinforcement materials are synthesized in house for simplified extrusion processing, Systematic synthetic engineering has resulted in a shape memory polymer (SMP) hybrid polyurethane resistant to Exxon Isopar L and mechanically stable over -40degreesC to 40degreesC, with ~Shore A80, and>100% elongation. NanoSonic shall continue to work with our defense prime partner to optimize beamforming and noise reduction. NanoSonic will deliver a nominal 1-3"by 30m Thinline SM-MR MOD hose to increase the TRL to 7-8 during Phase II, and for strum reduction verification at Carderock in Phase III. TRL 9 shall be reached upon completion of a NAVSEA Engineering Change Proposal (ECP) and incorporation of the SM-MR MOD hose into TB-29A sonar arrays.
