The objective of this investigation is to learn how to operate sonar transducers at power levels above the commonly accepted limit at which cavitation occurs, but without cavitation. This can be done when the ocean water surrounding a sonar transducer or sonar dome possesses tensile strength. Tensile strength in effect acts as if additional statis head were present at the transducer. Proper materials and constructional techniques must be used on a transducer or a sonar dome to permit this tensile strength to be utilized. The conclusion is that considerable performance gains can often be achieved by using the techniques developed in this program. A high-performance, noncavitating sonar system, utilizing tensile strength, appears feasible on the basis of the tests performed. Author
