AN/BQR-7/DT-276 Hydrophone Failure Mode Analysis.

Abstract

As part of the Transducer Replacement Criteria Task (3B) of Contract N00024-67-C-1168, Failure Mode Analyses were conducted by TRACOR on six defective DT-276/BQR-7 hydrophones removed from the USS PLUNGER (SSN 595) in Summer 1967. Results of the analyses indicate that the hydrophone failures occurred in two steps. Initially, the hydrophone cable began to hose when its watertight integrity failed. The hosing subsequently permitted moisture to enter the cable sleeve portion of the hydrophone, causing unsatisfactory electrical characteristics. (Author)
