  "Preliminary skeletal operations plan for Apollo :" a systems engineering support document.

  The Preliminary Skeletal Operations Plan is a statement of the operational concept for Apollo. This draft contains a description of the conduct of the Apollo LOR landing mission and a mission profile. It provides the basis for more detailed mission planning, for generating functional criteria for equipment design, and for measuring the adequacy of the current Apollo hardware for satisfying operational needs.

  Development of LOX/RP-1 engines for Saturn/Apollo launch vehicles.

  The development of liquid rocket engines follow similar patterns regardless of engine size. During the development of the H-1 and F-1 engines, may problems were encountered. Mehtods of solving the combustion instability problem are discussed.; AIAA 4th Propulsion Joint Specialist Conference, Cleveland, Ohio, June 10-14, 1968.; Also available on NASA Technical Reports Server (NTRS) as unclassified. Can be ordered. Also on AIAA.

  "Extensions of Saturn."

  This paper discusses the possible applications of Saturn vehicles to future space exploration. Potential missions utilizing Apollo derived hardware are examined. Research, development, and operations in earth orbit as well as lunar exploration, unmanned and manned interplanetary exploration are reviewed. These hypothetical missions are discussed in the context of the present and potential capability of three configurations of the Saturn vehicle; an uprated Saturn I, a three-stage Saturn V and a four-stage Saturn V. NOTE: Work presented herein was conducted by the Douglas Missiles and Space Systems Division under company-sponsored research and development funds. Therefore, the concepts and objectives described within this paper reflect the opinions of the authors and do not necessarily constitute endorsement by NASA, the Air Force, or any other U.S. Government organization. The nominal performance numbers presented are typical of the current configurations and possible future vehicle configurations.

  "Materials in space exploration."

  This paper presents a general review of major structural alloys that have been used in liquid rockets and space vehicles, the current state-of-the-art as applied to the Apollo launch vehicle systems, and discusses some materials currently under development for future requirements in vehicles for space exploration. Some aspects of the importance of corrosion resistant materials and suitable protective measures are discussed, as applied to both flight hardware and associated ground support equipment.

  "Saturn Apollo guidance error estimation."

  A brief sketch of the development of the equations for a weighted least squares estimator is given, the equations for both collective and recursive estimators being included. Four possible problem sources that may be encountered in the application of the estimator are identified. Various "success" parameters are defined in an attempt to predict the success with which, the method has been applied. The application of the estimation technique to the problem of computing various error parameters associated with the ST-124M guidance platform is described with the numerical results obtained using a manufactured data case are presented. These results are used to form conclusions about the effectiveness of the "success" parameters and preferred approaches to the problem of system evaluation using techniques of estimation theory.
