Effects of High Power Transmissions on Goodyear Elastomeric Dome Panels.

摘要

The Goodyear Aerospace Corporation, under BUSHIPS Contract No. NObsr-91065, has been determining the critical factors that affect the design, fabrication, installation, and test of a reinforced elastomeric sonar dome window for a bow-mounted AN/SQS-26 sonar transducer. The proposed dome is to be water-filled and pressurized to withstand anticipated service conditions. In support of this study, Goodyear made arrangements with the USN Underwater Sound Reference Laboratory for the measurement of the acoustical characteristics of several elasttomeric panels. After these measurements were completed, Goodyear treated the surfaces of two of the panels with antifoulant materials and sent the panels to USL for exposure to the same high-level sound pressures that are experienced by the AN/SQS-26 sonar dome. The purpose of this exposure was to test if the high acoustic energy was deleterious to the elastomeric materials. (author)
