ABSTRACT:
A baffled conformal blanket sonar array utilizes a corrugated or indented action plate and a sound isolation baffle of non-uniform thickness. A plurality of compliant tubes embedded in an elastomer on the interior side of the reaction plate permit the baffle's sound isolation function to remain constant in areas of differing baffle thickness. Sensors, associated components, cabling, etc. are embedded in an elastomer which fills the corrugations or indents on the exterior side of the reaction plate. An elastomer sheet covering forms a smooth even external surface. The result is an array which is thinner, lighter and more damage resistant than existing arrays.
