DESIGN AND DEVELOPMENT OF A MINIATURE NON RECIPROCATING CLOSED-CYCLE CRYOGENIC COOLER. PHASE I.
Abstract
An analytical and development program for devel opment of a miniature nonreciprocating refrigera tor is described. The objective of the present development is two watts of refrigeration for an IR detector at 77 =7 K with a life expectancy compatible with operation in space. The results of preliminary testing and analysis are extreme ly encouraging. A suitable gas bearing design appears to have been found. Feasible compact heat exchanger configurations have been devel oped. A miniaturized first-stage compressor impeller and a complete experimental turbo alternator were fabricated and tested with a reasonable degree of success. (Author)
