Etude d'Evaluation des Concepts de Refrigerateurs Mecaniques Applicables a des Missions Spatiales (Evaluation Study of Mechanical Refrigeration Systems for Application to Space Missions)

摘要

Mechanical refrigeration systems to provide 100 mW power at 4 K are studied. A two stage Stirling system, a Joule Thomson system with mechanical or absorption mechanics, and magnetic cycle refrigerator are considered. Preliminary specifications for all three types of mechanics are given. Magnetic suspensions are included in the design of the Stirling Machine. The planning of the development is outlined.
