Abstract : On the Centaur vehicle, thermal control is required for maintenance of the cryogenic propellants, for proper functioning of electronic equipment, and for rocket engine re-starting. Heat input to the vehicle occurs through the absorption of radiant energy from the sun, earth, and moon, and from power used to operate electronic equipment. Heat is dissipated by evaporation of cryogenic propellants and by radiant emission to outer space. In both the absorption and emission of radiant energy, a considerable latitude in heat flux is possible through the use of surface coating materials. A series of proposed coatings to provide the required thermal radiation control for various parts of the Centaur has been evaluated in the laboratory, and the results obtained are presented in this report.
