Mainstream Engineering Awarded Contract from NASA for a Single-Loop Thermal Control System Compressor

ROCKLEDGE, FL — [Date Nov. 21, 2019] — NASA is currently seeking technologies that will support the use of single-loop thermal control systems (TCSs) aboard spacecraft for human class missions.  Mainstream has developed compressor technology that enables a single-loop, two-phase TCS to replace the current two-loop TCS.  NASA has historically used two-loop TCSs to mitigate crew toxicity risk, whereby one loop collects heat within the crew module (CM) with a low-toxicity fluid and transfers the heat to a second loop in the external service module (SM) that rejects heat through the radiators.  Mainstream’s unique approach eliminates the intermediate heat exchanger and duplicate components (pumps, valves, etc.) resulting in a system that roughly 1/4th the mass of the current system. The compressor is by far the most critical component to develop and this effort focuses on the experimental demonstration of this unique compressor.  Mainstream has tremendous experience in this area having developed high-G compressors for military aircraft as well as the development of the refrigerant compressor used in the refrigerated centrifuge on the International Space Station. Mainstream’s approach leverages their prior experience
