Research abstract

FUTURE MILITARY SPACE MISSIONS WILL INTRODUCE SIGNIFICANT NEW TECHNOLOGICAL NEEDS FOR SPACECRAFT ENERGY SYSTEMS. HEAT PUMP AUGMENTED SPACECRAFT HEAT REJECTION SYSTEMS HAVE THE POTENTIAL TO REDUCE RADIATOR SIZE AND SYSTEM WEIGHT. VAPOR-COMPRESSION HEAT PUMP RADIATOR CONFIGURATIONS FOR SPACECRAFT HEAT REJECTION SYSTEMS ARE BEING INVESTIGATED. CONVENTIONAL HEAT PUMP COMPONENTS THAT MUST BE REDESIGNED FOR ZERO-GRAVITY OPERATION ARE BEING HIGHLIGHTED WITH PRELIMINARY MODIFICATIONS IDENTIFIED. SEVERAL VAPOR-COMPRESSION HEAT PUMP CONFIGURATIONS INCLUDING MULTISTAGE HEAT PUMP PAIRS ARE BEING INVESTIGATED. IN ADDITION, SEVERAL THERMALLY DRIVEN HEAT PUMP CONCEPTS ARE BEING EXPLORED. NOVEL HEAT PUMP RELATED THERMAL ENERGY STORAGE AND TRANSPORT DESIGNS ARE ALSO BEING CONSIDERED. A CANDIDATE HEAT PUMP CONFIGURATION IS BEING PROPOSED FOR FURTHER ANALYSIS AND CONSTRUCTION DURING A LATER EFFORT.
