Abstract:
This report covers Phase I effort in an exploratory development program to evaluate the Vuillemier heat driven refrigeratiion cycle for aircraft and spacecraft cryogenic applications. The effort includes a study of the theoretical aspects of the cycle and development of three miniature breadboard cryogenic refrigerators based on the cycle and operated by electric powered heating capsules. Two of the breadboard units are of identical design; these deliver 2 watts cooling capacity at 77 degrees K. The remaining breadboard is a two-stage unit designed to deliver 0.5 watt aat 30 degrees K and 5 watts at 75 degrees K. Performance data from these units were incorporated in the theoretical study. All units met their design requirements and confirmed the feasibility and inherent advantages of. The Vuillemier cycle for miniature long-life cryogenic refrigerators for both aircraft and spacecraft applications.
