Advanced Compressor for Long Life Space Cryocoolers

Abstract

The objective of the program was to demonstrate the advantages (high reliability, low weight, and long life) of hermetically sealed diaphragm-type compressors intended for space cryocooler applications. To accomplish this objective, a "proof-of-concept" compressor was designed, built, and tested. The compressor was designed to drive a 30-k, O.5-W orifice-pulse-tube cryocooler under development by the National Institute of Standards and Technology (NIST). Compressor design requirements were developed around the pulse-tube cryocooler requirements in an effort to optimize overall cryocooler performance. During the program. excellent test results were obtained. With the compressor operating within 1.2 percent of its design frequency, stroke, mean pressure, pressure amplitude, and phase angle, the pressure volume (nv power and estimated compressor efficiency exceeded design values by approximately 4 percent.
