S-RAM Dynamics (S-RAM) proposes to design, fabricate, test, and commercialize a high-performance axial piston transcritical CO2 energy recovery compressor (ERC) to support next-generation aircraft thermal management systems for the U.S. Air Force and commercial applications. The S-RAM ERC will be developed and commercialized with the support of the Rolls-Royce Thermal Management System team and Purdue University. The CO2 ERC will be commercialized within five years and will be manufactured in the United States.
