CRANE-84310
Modern naval warfare makes extensive use of both passive and active sonar from waterborne vessels, aircraft, and fixed installations. It is often desirable to deploy a large number of transducers in a planar array in order to provide a thin acoustic projector having a high acoustic source level.

Naval Surface Warfare Center, Crane Division (NSWC Crane), has developed and patented a mount for underwater acoustic projectors to mount cymbal transducers in an array. This system has a resilient sheet with a plurality of mounting apertures therein. Each mounting aperture has an annular groove formed about the inside surface of the sheet to accommodate one of the acoustic transducers.

Advantages:
-Provides a thin mounting structure for cymbal transducers
-The mounting system does not interfere with transducers' acoustic radiation
-Does not transmit radial vibration

Potential Applications:
-Military
-Naval warfare
