PARAMETRIC ANALYSIS OF DOME-TRANSDUCER INTERACTIONS

Abstract

This memorandum presents some results of a parametric analysis of the interaction of sonar domes and transducers during transmission. The results were obtained from the numerical evaluation of an analytical model consisting of a cylindrical transducer and concentric dome. The dome-transducer parameters considered in this study include dometransducer spacing, transducer diameter, transmitting frequency, dome thickness, and material properties of the dome. The parameter ranges include values appropriate to the AN/SQS-4, AN/SQS-23, and AN/SQS-26 systems. The results are presented as functions of the dimensionless products of the dome-transducer parameters. In this form, the results represent an initial effort at formulating guidelines which have broad application in dome design. The results show that the dome produces a degradation of each of the performance criteria compared to a bare transducer. The effects of the dome can be reduced, however, by proper choice of dome parameters. It is shown that the product of dome material density and thickness (surface density) is the most important parameter in determining the effect of the dome on transducer performance.
