Electroacoustic Projector Design Guidelines for High Source Level, Long Duty Cycle Applications

Abstract

In an effort toward the development of guidelines for consideration of thermal properties of ceramic in the design of electroacoustic projectors, a mathematical model for predicting changes in ceramic temperature of projectors operating at the high power levels was developed and tested. The change in ceramic temperature as a function of heat dissipated in the ceramic was measured for two projectors under various operating conditions at ARL's Lake Travis Test Station. A determination of the unknown constant of proportionality gamma was made on the basis of the data obtained. The average value gamma should be useful in estimating temperature rise in a sonar array similarly constructed, using Channelite 5400 ceramic elements. The extent this value of gamma can be extrapolated is unknown at present.
