Deep Space Cryocooler System (DSCS), Phase II

Metadata Updated: February 28, 2019

The Iris Technology and Lockheed Martin team has developed a cryocooler system design which meets the S1.09 SBIR topic goals at twice the desired cooling capacity (0.4W at 35K) delivering Engineering Model hardware under DSCS Phase II for both the cryocooler and its optimized control electronics. The DSCS Program builds off the previous successes of the USAF "MicroSat Cryocooler System (MCS)" Program (FA9453-14-C-0294). The DSCS extends the Miniature Low Cost Cryocooler Electronics (mLCCE) performance reducing size, weight and power of the deep-space rad-hard integrated circuits. The DSCS enhances the thermo-mechanical unit with a new inertance tube and regenerator packing to optimize the cryocooler design for 35K cold-tip and 150K heat rejection temperatures. To achieve this higher performance, the DSCS cryocooler is based on the Lockheed Martin Space Systems Company (LMSSC) TRL-6 High Power Microcryocooler. LMSSC's initial trade study shows the predicted performance of the High Power coldhead is significantly better than the standard coldhead. This is largely due to a greater regenerator volume, and thus greater regenerator heat capacity. The High Power coldhead heat exchangers are slightly larger, increasing their effectiveness and improving performance. In addition, Iris proposes the Phase I electronics design will be reviewed against sample planetary mission parts lists in Phase II. The uLCCE provides a mission-critical, radiation tolerant system solution, easily extendible to a radiation hardened flight platform.
