Abstract
A flextensional transducer for use in surface ship applications requiring the capability of withstanding underwater explosive shock is described. The transducer includes a plurality of ceramic stacked drivers disposed between an elliptical outer shell having opposing slots disposed along an inner surface of the shell and a flextensional limiting support block. The drivers are mounted on ball joint sockets which allow pivoting during high acceleration loading conditions. The support block further has a pair of curved surfaces which will generally follow, in close proximity, the inner surface of the shell and a member coupled to the opposing slots of the elliptical shell. The block can be fixed to a rigid mount disposed over at least one end of the transducer using a plurality of tie rods.
