  "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.

  "Nondestructive testing of space vehicle liquid propellant rocket engines."

  Presented at the Western Metals Congress, Los Angeles, California, 15 March 1967.; Archive copy is a photocopy.; ABSTRACT: This report describes the various nondestructive test methods employed to evaluate materials and processes used in the manufacture of large liquid propellant rocket engines at the Rocketdyne Division of North American Aviation, Inc. The contents of the paper were purposely oriented for an audience of aerospace, design and materials engineers. A brief description of liquid propellant rocket engine reliability is presented. The relationship of standards and specifications to nondestructive testing is discussed and various test methods are described along with a discussion of their applications and limitations. The sequence of events leading up to the use of nondestructive testing in production inspection is presented. Finally, the organization of labor directly related to nondestructive testing is given.

  "Juno V Transportation Feasibility Study (U)."

  The purpose of this report is to present an investigation to determine the feasible, practical and economical method of transporting the JUNO V thrust unit. This includes the first phase of transporting between Fabrication Laboratory, Systems Analysis and Reliability Laboratory and to the test stand, as well as the later phases, onto the Redstone Arsenal loading docks and from there down the Tennessee, Ohio and Mississippi Rivers to the Atlantic Missile Range, Florida.; Transportation and Packaging Section, Systems Support Equipment Laboratory.
