Multistage Cryocooler for Remote Cooling Applications

Next-generation missile midcourse detection infrared sensing systems will require improved cryogenic cooling technology. Future cryogenic cooling systems must be capable of providing significant cooling capacity at two different temperatures across a two axis gimbal or to multiple locations on a spacecraft. These capabilities will enable reduced payload jitter, lower overall spacecraft mass and reduced power requirements. Redstone Aerospace proposes an innovative Stirling/J-T hybrid cryocooler that offers unique capabilities and meets the STSS mission requirements.
