Current Mechanically Pumped Two-Phase Thermal Control Loop Developments

摘要

After a general introduction on two-phase thermal control system issues,the paper reviews the status of and lists commonalities and differences between the only two currently developed aerospace-related mechanically pumped two-phase thermal control systems.These are the Russian Segment Active Thermal Control System (RSATCS) hybrid two-phase ammonia thermal control system for the Russian segment of the International Space Station ISS,and the Tracker Thermal Control System (TTCS) hybrid two-phase carbon dioxide thermal control loop for the AMS-2 attached ISS payload.
