Abstract
ORBITEC proposes to develop the Magnetically Coupled Helium Recirculation Fan (MCHRF), a fan for the recirculation of cryogenic helium gas for shipboard High-Temperature Superconductor Deguassing (HTSDG) systems. The MCHRF will eliminate the mechanical penetration required for the recirculation function by driving the fan with magnetic forces from a tightly packaged integral motor assembly contained entirely within the vacuum space. This will simplify the design of the associated insulation system, eliminate the potential for any gas leaks along a shaft penetration, and minimize the heat load associated with the fan. Because of these simplifications, it will also dramatically reduce the cost associated with the recirculation function.
