Abstract
A composite split cylinder transducer comprises an electromechanical driver and a cylindrical shell having a longitudinal gap. The shell further has a portion, disposed opposite the gap, comprised of a high strength material having increased stiffness. Transducers of this configuration are capable of being employed at greater ocean depths where high hydrostatic pressure conditions exist with little effect on acoustic performance.
