Design, Performance, and Testing of the Lockheed-Developed Mechanical Cryocooler
Lockheed has developed a split-Stirling cycle common compression space cryocooler that provides more than 1.5-W cooling at 55 K, while drawing less than 50 W/W into the compressors. The design improves on the flexure spring and gas-gap seal design originally developed by Oxford University. Significant design improvements have been incorporated in the compressor and displacer, yielding improved cooling and efficiency, resulting in the measured performance achieved to date.
A description of the Lockheed Model L-1710C cryocooler and a summary of its performance and environmental test program are presented next.
