"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. -

"Saturn base heating review."
The Saturn I booster which is powered by a cluster of eight rocket engines has been successfully flown on four successive flights. The early success of this large launch vehicle is a strong indication of the soundness of its base heating program. This paper summarizes the thinking that went into the design of our base configuration. Flight test results indicate that pressures, temperatures and heating rates were generally as expected. New techniques have been investigated for generating design data. It has been found experimentally that pressure and thermal fields establish themselves in one to three milliseconds and that data from the "short duration" technique compare favorably with "long duration" type tests. As a result, the new "short duration" technique has become the standard for generating design data for the Saturn vehicle. -

"Corrosion problems associated with the Saturn space vehicles."
Corrosion problems associated with space vehicles, in general, are discussed as contrasted to those problems experienced with structures in an earth atmosphere. Primary emphasis is placed on structural alloys in this discussion, although some corrosion failures experienced in various mechanical components are described. General corrosion prevention measures are indicated, and solutions to specific corrosion failures described. Major failures experienced have been attributed to stress corrosion cracking, rather than general or galvanic type corrosion. Most such failures have occurred with only five different materials: three aluminum alloys - 7075-T6, 7079-T6, and 2024-T6; and two precipitation hardening stainless steels - 17-7PH and AM 355. Corrective actions were different in each case, but involved either a complete change to another material, a change to a different temper of the same alloy, or a modification of the heat treatment and/or general processing techniques. General conclusions are that the types of failures described could be avoided by: a more suitable selection of alloys in the initial design, a realistic review of the environments that could be encountered in the service lifetime of the component, lowering stresses, improving process controls, and effecting better familiarization of design personnel with the with the overall stress corrosion problem in an effort to reduce human error.; Preprint 18e.; Materials for re-entry and spacecraft systems - spacecraft materials.; Materials Conference, Philadelphia, Pennsylvania, March 31 - April 4, 1968. -

"Saturn S-II stage program plan."
This documents outlines the S & ID plan to fulfill the requirements of Contracts NAS7-80 and NAS7-200 for the design, development and manufacture of the Saturn S-II stage.; APPROVED by R E. Greer, Vice President and S-II Program Manager.; This reissue supersedes all previous issues of this report.; FOREWORD: The S-II stage is 81.5 feet in length and 33 feet in diameter, with a usable propellant capacity of 970,000 pounds, The S-II propellants are fully cryogenic-liquid oxygen at -279 F and liquid hydrogen at -423 F. Its five-engine cluster provides one million pounds of thrust. The stage is a cylindrical structure of relatively light weight with a shell designed to resist all loads without the use of stiffening members. Its skin is of welded aluminum panels, as are the elliptical bulkheads of the fuel and oxidizer tanks. Unique to its design is the common bulkhead that separates the -423 F liquid hydrogen from the -247 F liquid oxygen. The common bulkhead - a sandwich of two 33-foot diameter aluminum domes separated by an insulating filler of honeycomb - eliminates the weight penalty that would be imposed by the second bulkhead in more conventional design. This document describes the S & ID program plan for development of the S-II stage and associated a support equipment. -

"Saturn Vehicle Cryogenic Programs."
Paper from the 1965 Cryogenic Engineering Conference at Rice University, Houston, Texas, paper K-4. The abstract states, "This paper covers the cryogenic propellant and gaseous application to the George C. Marshall Space Flight Center Saturn Programs. Emphasis is placed on the overall application and the resultant logistic considerations. The planning of facilities, storage, and transportation required to ensure an adequate supply of cryogenic fluids when needed is traced from the engine and stage requirements. The entire cycle of technical requirements, estimating the quantities required from production and management of the program is developed, spacecraft application and other trends that affect cryogenic production are reviewed." -
"Ground Equipment to Support the Saturn Vehicle."

"A 'Zero Stage' for the Saturn IB Launch Vehicle."
To meet the demands of increasing payload size and weight, and to fill the large payload gap between the Saturn IB and Saturn V, a number of methods of uprating the Saturn IB have been studied by NASA and Chrysler Corp. of providing increased payload capability is discussed in this paper. Four 120 in. United Technology Center UA-1205 solid propellant motors, originally developed for the Air Force Titan III program, are clustered around the S-IB first stage of the Saturn IB launch vehicle. These four solid propellant motors provide the total thrust for liftoff of the vehicle, with S-IB stage ignition occurring just prior to burn-out and separation of the solid propellant motors. The term "Zero Stage" is applied to this added stage. -
