Feasibility Study of a Sonar Dome Window for the AN/SQS-26 Sonar Dome. Supplementary Report.

Abstract

Model test results demonstrated that it is feasible to fabricate sonar domes of the size of the AN/SQS-26 in one piece, using polyester tire cord and air-cured polyurethane. The acoustical properties of the polyurethane and polyester tire-cord type construction are not equal to those of natural rubber and polyester tire-cord constructions. Antifoulant coatings and the physical properties of the polyester and steel wire were not degraded by high-power acoustic energy. Likewise the sound transmission values of the panels were not degraded due to the application of the antifoulant coatings or by prolonged operation. Acoustic tests showed that db loss increases as the frequency increases. These tests also established that the db loss decreased as the pressure on the panel was increased.
