Development of the Moving Belt Radiator (MBR) as an advanced space radiator concept is discussed. The relative merits of Solid Belt (SBR), Liquid Belt (LBR), and Hybrid Belt (HBR) Radiators are described. Analytical and experimental efforts related to the dynamics of a rotating belt in microgravity are reviewed. The development of methods for transferring heat to the moving belt is discussed, and the results from several experimental investigations are summarized. Limited efforts related to belt deployment and stowage, and to fabrication of a hybrid belt, are also discussed. Life-limiting factors such as seal wear and micro-meteoroid resistance are identified. It is shown that MBR designs compare favorably with 5-8 kg/m2 Heat Pipe Radiator Technology at both 300 K and 1000 K temperature levels. It is concluded that additional efforts is required to resolve critical technology issues and to demonstrate the advantages of MBR systems.
