Future military space missions will introduce significant new technological needs for spacecraft energy systems. It is generally accepted that spacecraft heagt rejection systems that use heat pumps to boost the radiator temperature will reduce the radiator area. However, these systems must also result in weight savings and high reliability. This paper reviews the potential benefits of an innovative, spacecraft heat pump thermal-management/thermal-transport loop for high-power applications. Increasing stringent thermal requirements are projected for future spacecraft. Compliance with these requirements necessitates the development of thermal control techniques with capabilities far exceeding those in current use. A fundamental consideration is a heat transport and thermal rejection system capable of accommodating large heat loads, high energy densities, long transport distances, variable duty cycles, and varying operational parameters. The trend has been a progressive movement from heat pipes, that is from passive transport systems to active pumped systems. The increased operational requirements of future spacecraft thermal loops are forcing this continued evolution.
