  "Saturn V S-IC stage engine gimbal actuation system."

  The actuation system for the Saturn V S-IC stage is described and compared to the Saturn I system. The use of mechanical feedback actuators that result in a significant increase in system reliability and the damping of load resonance is discussed. The unprecedented component sizes and system requirements are cited.

  "Redundancy employing majority voting for a Saturn servoactuator."

  R-ASTR-NF.; ABSTRACT: The servoactuator was developed to improve the reliability of the Saturn S-IVB thrust vector control system by insuring continued system operation if single point failures occur. The selection of the majority voting technique is discussed. Its simplicity is cited along with the advantages of minimum weight, size, power consumption, and compatibility with existing control electronics. Operational features, design mechanization, and the analysis of test results are covered.

  "The Development of Servovalves with Improved Reliability for Space Vehicles."

  Considerations for improvement in the reliability of the Saturn engine gimbal servosystems are briefly covered. The Saturn I servovalves operate with increased electrical input power. The Saturn V vehicle stages will use mechanical feedback actuators with increased electrical input power, larger orifices and nozzle sizes, larger torque motor wire size, and greater spool driving forces.
