Non-Metallic Transducer Mounting Brackets (AN/BQQ-5/6 Spherical Array Transducers)

Abstract

Failure of transducer metallic mounting hardware due to corrosion has a significant impact on the fleet in terms of maintenance costs and systems availability. An obvious solution to the corrosion problem is to avoid using metallic materials. The most stringent requirement of the mounting bracket is the ability to withstand explosive shock. Molded non-metallic TR-317 mounting brackets consisting of three different resin-filler material systems have passed explosive shock testing per MIL-S-901-D. The TR-317 transducers were held on the non-metallic brackets with commercially available non-metallic nuts. All of the non-metallic brackets survived the test. This report details the design requirements, material selection, material testing, finite element analysis, bracket design, and first-article testing of the non-metallic mounting brackets.
