"Flat Cable Engineering Studies for Saturn S-IVB Vehicles."

This paper describes the engineering approaches, investigations, results and conclusions of two National Aeronautics and Space Administration (NASA) flat-cable contracts from the George C. Marshall Space Flight Center (MSFC) to the Douglas Aircraft Company, Inc., for feasibility studies on the S-IVB stage of the Saturn Vehicle. In addition, the objectives and approaches for a third contract., "Flat-Cable Engineering Study", are discussed. A sister Douglas Paper No. 4186, to be presented by Dr. P. L. Hill, covers in detail the manufacturing aspects of the Flat-Cable Development Program.; Prepared by R.A. Klotz, Advance applications, Saturn Electronics, Missile and Space Systems Group, McDonnell Douglas Corporation for presentation at: IPC/EDN Flat-Cable Seminar, University of Southern California, Los Angeles, California, 20 June 1967.

"Juno V Space Vehicle Development Program."

This report io the second in a scrics of reports on the JUNO V Space I Vehicle Development Program and indicates the present status of the overall I program. The objective of the overall program is to provide a reliable, economical, and flexible carrier vehicle with relatively large payload capability for orbital and space missions at the earliest possible date.

"Chilldown Electrical System for S-IVB Space Vehicle."

The paper is marked, "To be presented at the IEEE 1965 Aerospace Conference featuring Flight Vehicle Electrical/Electronics Systems, Houston, Texas, June 20-24, 1965." The abstract states "This paper presents the electrical system used to drive the chilldown motor pumps on the S-IVB space vehicle. This system consists of a 56 volt battery supplying power to the two three-phase solid state inverters which in turn drive two cryogenic motor pumps. Included in this paper is a short description of the overall chilldown system requirements. The advantages of the a-c system over the d-c system are discussed with emphasis on weight and reliability. Two functionally identical 1.5kva inverters were designed. One inverter uses germanium transistors in the output stage while the other uses silicon transistors. Both inverters were designed to have a quasi-square wave output. The inverter circuitry is described and the advantages of each is discussed including a comparison of weight, size, operating temperature, efficiency and voltage rating." Includes diagrams.
