Smooth Compliant Antifoulant Coatings. Advanced Conformal Submarine Acoustic Sensor (ACSAS) Outer Decoupler Research and Development

Abstract

Fiber reinforced composites provide a wide array of structural and acoustic properties. The composites may be isotropic and extremely anisotropic and offer considerable flexibility for designing underwater acoustic sensor flow noise outer decouplers. Compliant layers appear to be effective in suppressing flow noise. Effectiveness diminishes with depth, in part because of material compressibility and distortions caused by own ship's speed. Composite materials can be fabricated with high strength and modulus to maintain shape under severe loads.
