Abstract
This proposal is submitted by Johnson Research and Development Company, Inc., in collaboration with the Georgia Institute of Technoloqy. The proposed research comprises both analytical and experimental activities, including the construction and operation of a proof-of-concept experiment. The research will establish the feasibility of applying the patented Johnson TubeTM heat pump to external thermal control in manned spacecraft. This innovative device is very attractive for space applications due to its high efficiency, simplicity, low weight/power ratio, and few moving parts. Its efficiency theoretically approaches that of a Carnot cycle.
