This report presents the results of an engineering program conducted on the Model 120RD02. Constant Speed Drive used on the B-52H aircraft. The main objective was to provide the engineering data required to determine the technical feasibility of the hydrostatic-bearing system as a replacement for the roller bearing in the CSD. Analytical calculations were performed to establish the hydrostatic bearing design, and laboratory testing was conducted to obtain a quantified empirical comparison of the hydrostatic-bearing and roller-bearing configurations. In this report the details of the calculations and tests are presentd, the problem areas are examined, and corrective actions are recommended. The CSD is a hydraulically operated differential transmission that transfers and converts variable-engine-speed rotation to constant-speed rotation for the aircraft alternator. Since the alternator output frequency varies directly with the speed of rotation, the alternator must be driven at a constant speed so that a constant output frequency will be maintained. (Buehn)
