"Recoverable S-IB."
The paper deals with the selection of a simple recovery system for the Saturn IB first stage. As an introduction to the discussion on recovery system objectives, a plot of the expected trajectory is presented. This is followed by a statement which lists the necessary steps which must be followed to develop a recovery program. -
"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.
