Abstract
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.
The components of the S-IC stage engine gimbal actuation system are similar to and a direct evolution of those used in the Saturn I vehicle system.
The major system components are the fluid supply, a filter manifold, lines, and the actuators. The system is the essence of simplicity. As a fluid power source, fuel is taken directly in a single path from the high pressure side of the engine turbopump. Flow from the actuators is returned to the fuel system rather than to a reservoir.
Because of the small number of components and the design concepts used, the reliability of this system is high.
