NASA/GSFC 80 K Long-Life, Low Vibration Mechanical Cryocooler Performance Test Program Resultsoddard Space Flight Center. Design requirements provide 0.8-W cooling at 80 K, while minimizing the specific power of the system and maintaining the exported vibration levels to less than 0.02 lb..The cryocooler design is based on the flexure spring and gas gap seal design originally developed by Ox

Multi-Stage Cryocooler for Space Applicationsat the cold stage, and up to a watt at the mid stage, for 75 W of input power. We have incorporated novel sensors that allow monitoring of the piston gap clearance to ensure that it operates without contact. We have measured thermal performance, output vibration, EMI, and the effects of launch vibra

Hughes Long-Life Linear Stirlings: A Status Reportix years. Particular interest is drawn to a compressor life test initiated in August 1992. Two teardowns of this hardware have taken place for wear evaluation; these results are included in this report. An initial teardown after 10,600 hours of operation in a horizontal orientation indicated an aver

Linear Drive Stirling Cryocoolers: Qualification and Life Testing Resultsation test programs. Texas Instruments has designed a complete family of coolers for these tactical applications and has completed qualification programs successfully for two of these designs. Tested were the cryocoolers for the Integral Detector Assembly (IDA) and the Javelin antitank missile syste
