  "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.

  "A review of the research origins of the LANCE weapon system -- Project hindsight -- Task 1 supplement."

  This report includes a discussion of 57 research and exploratory development events that have been identified as contributing significantly to LANCE. Forty-six of these are research events. Eight of the research events deal with LANCE aerodynamics, four with propulsion, 24 with solid-state components used in the guidance and control system,and 10 with the research origins of the materials and manufacturing processes used in LANCE. In addition, 11 exploratory development events are identified. The principal concern of this study has been the identification of further research origins of LANCE and the 46 documented events are its major product. A further concern and obligation of this study has been to provide HINDSIGHT with some additional data on the research phenomenon including some further observations on the nature and route of research utilization.; FOREWORD: The purpose of this report is to present a survey of fundamental research contributing to the successful development of the LANCE weapon system. Included in this report are discussions of research inputs to a number of LANCE systems and technology areas. The circumstances of these research contributions to LANCE are discussed. The implications of these examples of research utilization are analyzed and some general observations and conclusions on the research payoff phenomena are given. This report was requested by the Army Missile Command as a supplemental contribution to Project HINDSIGHT.; Contract No. DA-01-021-AMC-14693(Z).; Battle Memorial Institute ,Columbus Laboratories.; RSIC-627.; Includes letter from W. Metscher, Lt. Col. to Mr. David L. Christensen dated March 14, 1969.

  "Space age management or maintenance of technical capability during a period of retrenchment."

  On January 3Ist of this year the United States celebrated its tenth anniversary in Space. In just one decade we have seen our space program climb from an humble beginning (a 30.8-pound payload put into orbit with a jury-rigged rocket) to extra-vehicular-activity and the tremendous Saturn V vehicle capable, of putting 250,000 pounds into low earth orbit. We have seen it grow from a "quick and dirty" operation to a program which at its peak had approximately 380,000 industrial employees in excess of {dollar}5.O billion per year. The marshalling of this great management and technological team generated many "growing pains". A few years ago the hue and cry was, "Where are we going to get sufficient people with scientific knowledge and drive to implement the space program?" Industry, sometimes reluctantly, was pressed into tasks which required managerial and technical skills beyond those they then possessed.

  "Design Concepts of Ground DDAS in Saturn 1B/V ESE."

  In the Saturn IB/V programs the sheer quantity of data required for computer processing and ESE display makes it necessary to provide an efficient data acquisition system. For much of the data originating in the launcher this requirement is satisfied by the Ground Digital Data Acquisition System (DDAS). This paper provides a technical description of the Ground DDAS with emphasis placed on the unique design concepts of this telemetry system.

  "Effects of High-Pressure Hydrogen on Steels."

  Hydrogen embrittlement of steels is hardly a new subject, but the effects of high-pressure hydrogen have been treated in detail only more recently and to a much more limited extent. Thus, most investigations of hydrogen embrittlement have been concerned with hydrogen in metals, while for the high-pressure hydrogen problem, we are more concerned with metals in(in contact with) hydrogen. I believe there is a difference and, certainly,different mechanisms of embrittlement are at least possible.; Presented at the Central Florid Section, American Welding Society, Orlando, Florida, 14 November 1967 and North Alabama Chapter, American Society for Metals, Huntsville, Alabama, 16 November 1967.

  "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.

  "Development Effort to Achieve Reliability."

  Presented at the 6th West Coast Reliability Symposium, University of California at Los Angeles, Los Angeles, California, 20 February 1965.The development of a large liquid rocket engine can represent the expenditure of several hundred million dollars of effort. Before 30 percent of the contracted development funds have been expended, however, the engine will probably have operated for the mission duration. The capability to operate at least one successful test early in a development program is evidence of achieving a minimal reliability level, but the major objective of the development program is producing a design which performs reliably. A rocket engine reliability prediction must view reliability as a dynamic concept, constantly being altered by development effort.

  "The significance of parameters affecting the heat transfer to the liquid hydrogen in the Saturn S-IVB stage for the lunar orbit rendezvous mission."

  The Saturn S-IVB stage has a requirement for orbiting around the earth for up to 4.5 hours with approximately 60 percent of its initial propellant remaining at the end of the coast (prior to restart) . Extensive analyses must be performed to insure that this requirement is met. Both the maximum and minimum heat transfer rates are important because the maximum rates affect the hydrogen boiloff losses and thus the initial propellant loading requirements. The minimum rates are important because the boil off gases are used to maintain a minimum axial thrust level by venting the gases continuously through aft facing nozzles. This provides for a settling of the propellant throughout the orbital coast and alleviates the need for periodically venting the tank under zero gravity.

  "Development of the Saturn S-IV and S-IVB Liquid Hydrogen Tank Internal Insulation."

  In April of 1960 the Douglas Aircraft Company was awarded a contract to develop the second and uppermost stage for the Saturn I space booster. In order to realize the high specific impulse available, this stage, called the S-IV, was to utilize liquid hydrogen and liquid oxygen as the propellants. After burn-out of the first stage, the S-IV Stage was to ignite its engines at an altitude of approximately 200,000 feet, burn for approximately 8 minutes, and inject a 20,000 lb spacecraft into a low earth orbit. This program represented Douglas's first major endeavor with liquid hydrogen. It was necessary to develop an insulation for the S-IV Stage that was capable of withstanding the thermal shock associated with loading, could provide adequate insulative properties to limit the flow of heat into the hydrogen, and was of minimum weight. This latter fact cannot be over emphasized because every extra pound of insulation is one less pound of available payload weight.
