NanoSonic specializes in the production of multifunctional, nanostructured morphing airfoils and hydrofoils via Shape Memory-Metal Rubber™ (SM-MR). SM-MR™ would be exploited as a smart towed array hose that can both sense and change its shape under sea-water to reduce damaging strum-induced vibration and optimize hydrophone performance. Our unique layer-by-layer self-assembly processing method yields ultra-lightweight (< 0.99g/cc), yet thick rugged and compliant nanocomposites enabling neutral buoyancy due to the extremely low volume fractions of metal nanoparticles required for conductivity. The electrically conductive component of SM-MR™ allows for 1) in-situ sensing of longitudinal flow at greater than 4 degrees and 2) wireless induction pathway stimulating temporary shape change to a more hydrodynamic cross-section to suppress crosswise flow and turn-induced strum and 3) repeatedly return to a circular cross-section upon turn completion. While the specific chemical structure of SM-MR™ is proprietary, the hybrid polyurethane SMP is resistant to Exxon Isopar L and offers similar properties (isothermal mechanical -40ºC to 50ºC, Shore A80, > 100% elongation) to BF Goodrich 58881. The TRL of the morph-on-demand SM-MR™ submarine towed array hose would be increased to TRL6 during Phase I and to TRL 9 when demonstrated at Carderock housing a TB-29A acoustic module in Phase III.
