Abstract:

This report presents the 9433 Despin Control anomaly investigations, resulting conclusions and recommendations. General recommendations are identified in two categories design changes and process changes. First category includes a retainer design, increase of DEA current limit to increase motor capability of DMA. Secondary design considerations are positive lubrication system, a flexure payload mechanism for the bearing race and a controller rate loop redesign to make the system insensitive to torque perturbations. Second category relates to the processing of metal parts, non-metal parts, bearing screening, lubricants, assembly and test procedures, and DMA handling and storage. Author
