Abstract : The report covers the period of a research program on the feasibility of the moving belt radiator. Primary concerns of the program were: Materials seizure, thermal conductance between contacting surfaces, fatigue of belt materials, high-temperature bearings (all in the hard vacuum environment of space). Many tests were run to assess compatibility of various potential drum and belt materials combinations, thermal conductance between contacting surfaces of test specimens under transient and equilibrium conditions, and suitability of various dry film lubricants and/or coatings for bearings. Assembly and checkout of a small-scale model moving belt radiator in an ultrahigh vacuum system were initiated.
