Abstract:

A detailed description and comparison is given of thermodynamic cycles suitable for use in space for the liquefaction and reliquefaction of He, H2, N2, F2 and O2 at rates from 1 lb day to 1000 lbsday. A survey is presented of the mode of operation, performance and efficiency of the following cycles cascaded compressed vapor cycles, systems using Joule-Thomson cooling only, system using expansion engines, Stirling cycle systems, Taconis cycle systems and miscellaneous systems. Tables and graphs are included presenting the significant data on performance of each suitable cycle based on conservative estimates of the current state-of-the-art and on optimistic estimates of the probable future state for the period 1965-1970. A survey is given of space environment and detailed discussions are presented on the question of component compatibility and design for space operation, particularly covering such matters as component weights, volumes and reliability.
