Research Institution
Future Navy combat ships, including CG(X) and related platforms will utilize an advanced degaussing system to reduce the hull magnetic signature. High temperature superconducting (HTS) cables are being considered by the Navy for the advanced degaussing system, because of the potential for significant weight, installation cost and operations cost reduction. In an ongoing Navy sponsored SBIR effort, the Tai-Yang Research Company is developing a quick disconnect terminal fitting that simultaneously makes electrical and cryogenic connections to an HTS degaussing cable. The proposed junction box will be based on TYRC’s proprietary connector design, and will include features to route cryogen from the cable to the cooling and circulation system, and connect the superconductors to an external power supply, in a compact module that minimizes system heat load. In Phase I, TYRC will explore design options for integrating the cryogen cooling and circulation system components, TYRC connectors and electrical feedthroughs in a common vessel. Alternative configurations for remote service connections or shared services among multiple cables will be considered. In Phase II, TYRC will build a prototype junction box and evaluate its performance under conditions relevant for Navy shipboard application.
