  "A Hybrid Simulation for Dynamic Verification of Saturn Guidance and Control Subsystems."

  This paper presents a discussion of a hybrid simulation used to dynamically verify the Saturn Guidance and Control subsystems. First, the Saturn vehicle is briefly described to provide background information. The Instrument Unit (IU) is considered in more detail to give a proper setting for the Guidance and Flight Control (G and FC) discussion that follows. After a brief description of the actual G and FC System operation, simulation models of the G and FC components are considered in detail. This is followed by a discussion of the model assignment to a particular computer (digital or analog) and justification for making that assignment. Finally, results of the AS-204/LM1 hybrid simulation studies are briefly considered with mention of the actual flight data.

  "A Nation Goes to the Moon."

  Written by NASA Office of Manned Space Flight Associate Administrator George E. Mueller, this is an article from G. E. Challenge, Fall 1966, page 26 to 32.

  "A new telemetry technique."

  A technique new to telemetry is discussed which promises to alleviate an enigma facing the telemetry engineer : How to adequately transmit the avalanche of vibration and other wideband data desired in the development phase of large missiles and launch vehicles. The data channels are stacked in the frequency spectrum as single sideband subcarriers which frequency modulate the RF carrier. The system design utilizes to advantage the statistical properties of vibration data to achieve maximum data transmission efficiency from the available RF carrier deviation. However, in contrast to proposed statistical predigestion techniques, the data is transmitted in raw form.

  "A Practical Approach to the Optimization of the Saturn V Space Vehicle Control System Under Aerodynamic Loads."

  This paper includes the equations for the bending moment of a launch vehicle with the effects of bending and sloshing dynamics. It also includes a comparison between the bending moment response envelope of the measure winds and the bending moment response of the MSFC synthetic wind profile.

  "A Prime Contractor's Reliability Program for Components/Parts for the Douglas S-IVB Stage Project."

  This paper, presented at the fifth annual Reliability and Maintainability Conference in New York City, contains a "prime contractor's reliability program for components/parts for the Douglas S-IVB stage project." These parts include special flight critical items and their complementary reliability engineering program plan is outlined in this paper.

  "A Program plan for earth orbital space astronomy."

  Manned space flight offers the opportunity to couple the astronaut/scientist's ability to select and process data and to calibrate, modify and repair instruments with the vantage point for astronomical observations provided by a platform located above the Earth's atmosphere. This paper briefly examines the role which manned space flight may play in the 1970-1990 time period in meeting astronomy research needs. The instruments and facilities which appear feasible for that period are described.; Paper presented by J. R. Olivier, National Aeronautics and Space Administration, George C. Marshall Space Flight Center and H. L. Wolbers, Ph.D, McDonnell Douglas Astronautics Company - Western Division, Advance Space and Launch Systems.

  "A Review of Cryogenic Technology Aspects of Space Flight."

  This paper was presented at the International Cryogenic Engineering Conference in Kyoto, Japan. It details the use of cryogenic technology in rocketry and how its usage created "many new techniques and deeply stimulated many fields of cryogenic technology."
