Abstract: ABSTRACT           A ring-shell projector capable of simple disassembly and reassembly.  The underwater transducer has a driving ring and a pair of flexible diaphragms on either side of the ring with their rims attached to the ring.  The ring is formed of an array of electrostrictive elements and spacer elements,  each spacer element having a pair of radial, outward extensions.  A pair  of  coupling  rings  are  provided  each  adapted  to  be positioned between the  rim of one  flexible diaphragm and  a corresponding  array  of  spacer  element  extensions  to provide sealing  engagement  between  the flexible  diaphragms  and  the driving ring.  Besides simplifying the repair of a projector, the  improved  design  is  more  versatile,  allowing  a  single driving ring to be used with different sets of shells, having different  resonance  frequencies and/or bandwidths.   Moreover, an expensive step in the construction of a ring-shell projector is obviated, namely, the bolt holes in the metal staves and the subsequent custom matching of the shell holes.
