Abstract
Energy efficient, cost effective, cryogenic distribution system (up to several miles) is strongly commanded for spaceport and in-space cryogenic systems. The use of magnetic levitation by permanent magnets and high temperature superconductors (HTS) results in without mechanical contact and thus, the conduction part of the heat leak can be reduced to zero. In Phase I, various magnetic suspensions, magnetic materials, insulations and mechanical stops for the cryo-maglev transfer line has been comprehensively investigated. Two demo modules of the cryo-transfer line has been designed and constructed. The cryogenic tests of the modules successfully demonstrate the vertical magnetic suspension, horizontal stability, and other important performances that have paved the solid ground for a Phase II project. In phase II, further optimizations of the designs and performances of cryo-maglev transfer lines will be conducted analytically and experimentally to meet the KSC technical requirements. The various warm supports (shape-memory-materials, bimetals, special magnetic structures, and special metal wires) will be studied. Two full sized prototype transfer lines will be designed, constructed and cryogenic tested at KSC. The proposed novel transfer line will provide potential of extending many missions, save cryogens, or reducing the overall launch mass to accomplish a given mission.
