Spacecraft communication
Unified S band
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.

"Flight Control Computer for Saturn Space Vehicles."
Flight control
The flight control computer for Saturn receives attitude signals from the stable platform, rate signals from rate gyros or lead networks, and angle-of-attack information from body-fixed accelerometers or other sensors.

"Flight Software Development Laboratory."
History
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.

Brazing
This work described in this report was performed for the National Aeronautics and Space Administration under contract NASw-16. Rocketdyne is now building the F-1 engine for the Apollo lunar mission. Five F-1 engines, each capable of developing 1-1/2 million pounds of thrust will power the first stage of the launch vehicle of Saturn V.

"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.

Astronautics
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.

Spacecraft control
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.

Helium
Saturn 5 launch vehicles
Helium is used extensively throughout the Apollo/Saturn V space vehicle for a number of applications. The welding use is not discussed since it is a special topic. In the first stage (S-IC), helium is used for liquid oxygen tank pressurization during vehicle checkout and launch.

Presented to Society of Automotive Engineers, Advanced Launch Vehicle & Propulsion Systems. When the Apollo lunar landing project is complete, the Saturn and Apollo hardware will only have begun to realize their ultimate potential for space exploration. The immense reserve of Apollo technology, facilities, and booster capability can then be directed to the achievement of national goals which lie far beyond the initial lunar landing. In achieving the Apollo lunar objectives, large investments will have been made in launch facilities, tracking systems, propulsion techniques, reentry systems, lunar landing systems and rendezvous technologies. Although developnent in these specialized areas has been tailored to the needs of Apollo, numerous studies by NASA and industry have demonstrated the feasibility of using the spacecraft, launch vehicles, and operating techniques for missions far more complex than lunar landings. Amortization of this hardware will prove cost-effective for missions of more sophisticated applications.
