The study investigates a Space Station Freedom (SSF) Central Thermal Bus (CTB) radiator array orientation profile that will meet the SSF 82.5 KW heat rejection requirement while maintaining radiator angular velocities under 45 deg/minute. The radiator orientation along with the amount of environmental absorbed heat and heat rejection capabilities without any consideration for the radiators exceeding the recommended maximum angular velocities were initially determined. The environments investigated were the minimum environment, alternate minimum environment, maximum environment, and a -80°F (-62.20°C) sink temperature environment. The collective data from the above environments were then used in order to recommend a radiator orientation profile that, under transient conditions, would meet the heat rejection requirements while maintaining the radiator angular velocities under 45 deg/minute, and prevent the ammonia in the panels from freezing. The worst sink temperatures were found for ß=52°, and were in the -62.50°F (-52.50°C) and -73.60°F (-58.67°C) range. The radiator angular velocities obtained in the recommended profile never exceeded 12 deg/minute for all the considered ß angles, and the maximum angular acceleration obtained was equal to 0.00444 deg/sec2.
