Abstract

A development program Is presently being conducted to design and fabricate a piece of hardware which will reliquefy a portion of the boiloff vapor generated from hydrogen storage on long space flight missions. A reliquefaction rate of approximately 40% of the hydrogen boiloff is anticipated. The other 60% is used as the heat sink and is vented overboard. The cycle Is fully described elsewhere [1].
