Abstract

Earlier studies [1, 2] have shown that partial hydrogen reliquefiers, having certain estimated weight and power requirements, can produce significant payload improvements in space missions requiring the long-term storability of liquid hydrogen. In these studies of potential thermodynamic cycles, the question of practicality of the required hardware was not given primary consideration.
