FLEXTENSIONAL RESONANT PIPE PROJECTOR

摘要

An underwater acoustic projector comprising a pair of spaced apart end walls with an acoustic driver positioned between the end walls, the driver having smaller cross- sectional dimensions than the end walls. The projector has a one piece thin wall inwardly concavely shaped shell with corrugations running in the axial direction surrounding the driver and mechanically coupled to the end walls. An open ended tubular waveguide (pipe) is connected to each end wall of the projector and extend outward forming a flextensional resonant pipe projector.
