Heating and Temperature Dependent Behavior Sonar Element. Laboratory Determination of Array Cooling Requirements under Simulated Operating Conditions.

摘要

In connection with the Advanced Surface Ship Sonar Project to develop an improved surface-ship sonar array, develop laboratory techniques for determination of the effects of temperature on ceramic longitudinal resonator behavior. Using these new techniques in conjunction with methods and results derived from work in Transducer Research and Development, determine the ceramic temperature range to be expected in a proposed sonar array during operation and further determine any artificial cooling requirements resulting from element performance changes over the operating temperature range.
