ABSTRACT:
A transducer assembly which includes a plurality of staves releasably arranged around the periphery of a torpedo. Each stave includes a transducer backing member such as foam polyurethane to simulate an air backing, and a solid acoustically transparent transducer support member, such as polyurethane, disposed in front of it. A curved reflector made up of a plurality of sheets of onionskin paper is positioned between, and compressed by, the backing and transducer support members. A plurality of transducer active elements is arranged vertically within the transducer support member with the arrangement imparting a certain desired directivity pattern to receiving beams associated with such apparatus.
