"S-IVB Saturn high energy upper stage and its development."
The development of carrier rockets For manned space missions has been one of the major activities in the aerospace field during the past decade. The early space efforts were made possible by the existence of large ballistics missiles. It soon became obvious that the delivery of weapons and the launch of large spacecraft could not be combined into one operational system in an efficient way; therefore, a family of spacecraft boosters had to be created. -

"Saturn S-IV cryogenic weigh system. Part I : propellant utilization."
In order to achieve maximum vehicle efficiency, it is essential that the vehicle propellants be loaded to desired values and that these propellants approach simultaneous depletion at the end of powered flight. To accomplish precise loading and assure minimum residuals, a highly accurate and repeatable, vehicle located, propellant management (PM) or propellant utilization (PU) system must be used. As the ability to load propellants to predetermined values depends directly on the ability of the system to accurately sense the propellant masses, it is essential that the system be calibrated with respect to propellant mass under conditions resembling those to be experienced during final loading and powered flight. The use of a cryogenic weight system will reduce the unknown factors in capacitance sensor element shaping, tank geometry, and propellant properties to a degree which will permit the determination of propellant masses to with .025%. -
"Saturn S-IV cryogenic weigh system. Part II : weigh operations."
Two basic methods for mass determination are: (1) direct measurement, (2) volume and density determination. Both methods or variations have been used to determine space vehicle propellant mass with varying degrees of success. Stringent propellant loading accuracy requirements of k0.5 percent for the Saturn S-IV Stage have led to the development of a Cryogenic Calibration Weigh System. The method employs accurate electronic force transducers and measuring systems as the standard and experimental weighings have verified achievement of better than the required accuracy. -
"Saturn S-IV cryogenic weigh system. Part IV : safety."
During cryogenic weigh system operation, hydrogen when combined with oxygen can create an unsafe condition. Therefore the concentration of the residual oxygen and hydrogen from leaks in the cryogenic weigh environmental bags must be known at all times during the cryogenic weigh. Hydrogen and oxygen detectors will provide the optimum method for maintaining safe conditions. Hydrogen properties and safe mixtures are reviewed. The method selected to analyze the oxygen content is discussed. The selection, development, and testing of a hydrogen detector system is examined. -

"Statistical model for Saturn electrical support equipment mission availability."
This report presents the logic leading to a mathematical expression for mission availability. Mission availability is treated as the probability that the cumulative downtime occurring during a mission of given length will be less than the time constraint. This is opposed to more general approaches such as steady state or instantaneous availability or operating time versus real time. We intend to present a practical and usable mathematical model by deduction and demonstration. The development is based on exponentially distributed downtimes. Experience shows that certain systems follow exponential downtime distributions except near zero. This error is often so small that it may be neglected. A future report will present a downtime distribution which will account for this small error. -

"The Case for Compatibility."
"The Case for Compatibility" is a paper by Robert L. Smith, Jr., who worked in Quality and Reliability Assurance Laboratory at George C. Marshall Space Flight Center. The summary states, "Ever since the use of missiles and space launch vehicles began, questions have existed in every program regarding the similarity between upstream (e.g., manufacturing, static firing ) and launch site checkout equipment. Programs have existed which utilized nearly identical equipment for both uses; other programs have existed in which any resemblance of the equipment was probably coincidental. Many factors have entered the final decisions, not the least of which were economic and schedule considerations, and, in some instances, the organizational structure of the developer." -
"The Challenge of Change vs the Control of the Process."
The introduction states, "This paper is designed to present the Rocketdyne engine program as it applies to the Saturn launch vehicles and will apply to the Apollo program of manned flight to the moon (Fig. 1). The vehicle that will launch this flight is the Saturn V, the largest and most powerful of the Saturn family. This vehicle, 362 feet tall and 33 feet in diameter, will be capable of sending a 45-ton payload to the moon or placing a 120-ton payload in earth orbit. Five F-1 engines power the first stage of the Saturn V; five J-2 engines, the second stage; and one J-2 engine, the third stage. The thrust of the first-stage engines alone will be equivalent to 160 million horsepower. Both of these engines, the F-1 and the J-2, were designed at, and are currently being produced by Rocketdyne." -

"Use of tank mounted booster pumps for providing NPSH to turbopumps operating in a radiation environment."
This paper outlines the results of a test program which was planned to demonstrate the feasibility of using a tank mounted, all-inducer, high speed liquid hydrogen booster pump to provide NPSH for the turbo pump in a reactor-powered vehicle. The cavitation problem associated with pumpoing liquid hydrogen, when used as a propellant, is further aggravated by localized heating caused by radiation from the reactor. -

"Uses of Saturn."
Saturn and Apollo hardware will not have realized their ultimate potential for space exploration after the project lunar landing is complete. To accomplish the Apollo lunar landing program, an immense backlog of technology, facilities, and booster capability will have been built up, and we believe proper utilization of this resource will fill the needs for planetary, lunar and earth orbital space exploration for years to come. -

"X-ray television inspection of aerospace weldments : Television x-ray image enlargement system for inspection."
A sensitive new television X-ray image enlargement system has been developed under sponsorship of Watertown Arsenal Laboratories (Army Materials Research Agency) by the Department of Welding Engineering of The Ohio State University. Now commercially-available through Philips Electronics Instruments (Norelco), complete systems have been in service since January 1963 in aerospace, electronic, and other facilities. Such users report highly- satisfactory performance and unusual reliability in service. The new X-ray system permits in-motion or stationary examination of critical aerospace materials, components, and systems such as sheet materials, weldments, brazed joints, electronic components, printed circuit assemblies, small mechanisms, and biological specimens.
