Outboard electrical cable arrays, particularly those in the Vertical Launch System (VLS), have had numerous failures which have led to the loss of weapon readiness and high maintenance/replacement costs. The failures can be attributed to the extremely aggressive environment in which the cables reside. Cables are housed in a free flooded zone, and routinely undergo hydrostatic, thermal, and mechanical stresses. When surfaced, the cables are exposed to air, and experience wet-dry cycles which tend to degrade jacket materials. Cable runs frequently come into contact with sharp metal objects such as angle iron and pass-through holes, which cause abrasion damage to the outer jacket. An improved cabling system with physical properties that meet the demands of this environment with a service life of 20+ years would result in substantial cost savings and improved weapon readiness. Texas Research Institute Austin, (TRI/Austin, Inc.) proposes the development and evaluation of two parallel approaches to solve these problems: 1. An innovative over-coating system for post-manufactured VLS cables 2. A new cable design using modern materials and CY 2000 manufacturing technology The Phase I effort includes development of innovative life testing procedures for comparing cost and performance effectiveness of the two approaches.
