This program will begin with the evaluation of candidate sonobuoy cable conductor and strength members materials and configurations using several special cble design computer programs previously developed by the proposer. The results of this study will be combined with recent sonobuoy experience to identify a minimum of six cable constructions which will be purchased and subjected to laboratory testing. These cables will include both single and multiple conductor cores and various strength member configurations including parallel, braided, and served constructions. Special attention will be paid to the development of cables having strength compatible cores which will survive prolonged cable cyclic tension loading. The objective of this program will be to identify improved cable configurations and manufacturing techniques which will provide reliable sonobuoy cables at a minimum cost.
