The objective of the program was to investigate the applicability of scroll fluid machinery (compressors and expanders) to cryogenic helium refrigerators or liquefiers for superconductive ship propulsion systems. Thermodynamic cycles for appropriate refrigerator/liquefier systems were analyzed; and, based on the results of this analysis, typical performance characteristics for a scroll compressor and a scroll expander suitable for these systems were defined. Design requirements for the scroll compressor, a 90 SCFM unit with a 16 to 1 pressure ratio, are established and a design for an experimental oil-lubricated unit suitable for laboratory testing is evolved. The design is based, in part, on information obtained from tests on the Arthur D. Little, Inc. (ADL) 1 to 3 Hp scroll compressor. The results of these tests are described. (Modified author abstract)
