NASA's future remote missions will employ advanced instruments and electronics that have stringent spatial and temporal isothermality requirements, in spite of extreme and variable environmental conditions. An advanced thermal control system (TCS) is needed to maintain their operating temperatures within a very tight range to maintain system functions. To meet this need, Creare has been working with JPL to develop two-phase pumped loop technologies, with a goal toward infusion into upcoming science missions. However, a critical uncertainty to retire is the component-level and system-level performance in microgravity. This uncertainty results primarily due to the differences that arise in two-phase (liquid/vapor) flow patterns and two-phase tank distributions when the gravity force is not dominant with the phase separator, evaporator, and accumulator. This paper details the design, assembly, qualification, and ground testing of a small two-phase pumped loop assembly for near-term suborbital flight testing.
