Smallsat Cryocooler System

The Iris Technology team which also include Northrop Grumman Aerospace Systems (NGAS) and the University of Wisconsin, is attacking the problem of high-efficiency, low-volume, space-qualified cryocooler systems.The team has a firm starting point by leveraging the Northrop Grumman Microcryocooler and the Iris Technology mLCCE (Miniature Low Cost Control Electronics).TMU enhancement will start with performing thermodynamic modeling of modified a NGAS microcryocooler for a heat lift of 2W for 20W spacecraft power and cooling to 110K with a 300K reject temperature.Analyses will be performed to reduce the TMU volume.The mLCCE design will be greatly reduce in size by utilizing a microprocessor based design with a GaN FET power stage.By enhancing proven technologies, the Iris Technology team provides a very high probability of success.Approved for Public Release | 18-MDA-9522 (23 Feb 18)
