  "Guidance and Control of Saturn Launch Vehicles."

  The navigation, guidance, and control modes and problems of the Saturn launch vehicles are given as the requirements for the guidance and control methods. Two path adaptive guidance modes, featuring flight path optimization, in the form of a polynomial mode and an iterative mode are given in their computation form and compared with respect to mission flexibility, implementation requirements, and performance. Attitude control during the propelled flight phases requires consideration of various bending and sloshing modes; stability of the control system is obtained by phase stabilization of the low frequencies and by attenuation of the higher frequencies. Typical shaping networks and their transfer functions are given. The attitude control system during coasting periods is briefly described. The functional behavior and characteristic data of the main guidance and control hardware such as the inertial sensors, stabilized platform, digital computer, data adapter, control computer, and actuation system are described. Reliability requirements are emphasized. The principle of redundancy is extensively used to obtain highest reliability for long operating times. Data and results from recent Saturn I flights summarize the performance of the guidance schemes.

  "Ground Equipment to Support the Saturn Vehicle."

  With the advent of the first large space vehicle, the SATURN, the ground support equipment and launch facility designer is faced with the necessity of conceiving and building an unprecedented launch system concurrent with the vehicle development. The paper intends to present a comprehensive picture of the problems involved and how they are solved. It follows the SATURN through the various modes of operation such as transportation over land and water, checkout, handling and erection, propellant loading, and describes the facilities at the launch site.

  "Furnace Brazing of Liquid Rocket Thrust Chambers."

  Brazing as a technique for joining metal parts has been utilized for centuries. Industry, however, has only begun to use it on a wide scale in the last twenty years. The rapid growth of brazing has been a result of consumer and military demands Tor products of lighter weight, less expense, and higher performance. Today, brazing is one of the most widely used fabrication techniques in the production of liquid rockets, gas turbines, refrigerator and other types of heat exchangers, automobile parts, vacuum tubes, and many nuclear products.

  "Flight Software Development Laboratory."

  A man-in-the-loop computer facility has been created using a digital computer, display terminal,and space vehicle flight computer to enable programmers to check out flight programs in a simulated space flight environment. The simulation requires a real time multi-programmed environment, which is supplied by a control system capable of scheduling programs on 32 levels of priority interrupt as well as answering demands for service at the display terminal. A special interface device permits visibility and control of the flight program as it executes in the flight computer. On-line inputs from the programmer at the display terminal and outputs from data collection and reduction routines to the display screen are executed in real time. The Flight Software Development Laboratory has proved to be very useful in reducing program preparation time and increasing flight program confidence.

  "Flight Evaluation of the Command and Communication System Aboard AS-501."

  The first test of the command and communications system, a unified frequency S-band system, aboard AS-501 was successful. Compatibility of this system with the MSFN/USB sites was established. The onboard transponder and antenna system including antenna switching performed as predicted. The command performance was excellent with 5747 valid commands received onboard out of 5748 commands transmitted. Data reduction problems prevented a complete analysis of the tracking data. Telemetry system performance was satisfactory with a measured bit-error-rate of 4 x10-5 while over the Ascension Island station. This flight provided valuable data which can be used to define vehicle to-ground-station interfaces, to establish attitude constraints during translunar injection, and to improve operational procedures. One more test as successful as the AS-501 test would qualify the system as operational.; May 3,1968.

  "Interface Problems in Space Experimentation."

  Space experimentation is expanding rapidly. Unmanned satellites are being equipped with precision instruments of greater power, and manned space stations accommodating large crews are in the drawing-board stage. The interface problems between these sophisticated instruments and between man, the spacecraft, and the supporting groundstations are multidimensional. This paper analyzes the scientific/technical areas of space experimentation, and continues with a review of the subsystems and support systems required to supply and operate the large variety of instruments. Areas of major integration efforts are singled out and the requirements for further developments and improvements are listed. A bibliography of 95 references is enclosed to assist in the identification of more detailed reports on all vital aspects of space experimentation.; Archive copy is a photocopy.; Supplement to IEEE Transactions on Aerospace and Electronic Systems, Vol. AES-2, No. 4, July, 1966. Pages 237 to 255.

  "Historical Summary: S & ID Apollo Program."

  Four and a half years have passed since President Kennedy and the United States Congress established a national goal of landing a man on the moon, before the end of the decade. This brief history is designed to be a working tool for use during the second half of this great adventure. It is expected that by presenting the events of the past in perspective this document will become a handy reference to accomplishments of the first half of the program. It is hoped that this volume will be of value to those directly and indirectly concerned with North American's portion of the Apollo program. This history contains a chronology of significant events, as well as material on the management of the program, a record of some of the breakthroughs in technology, a report of the hardware produced to date, and the many tests performed to man-rate the equipment.
