"Space flight : first draft."
Appears to be a rough dfraft with editorial comments and revision notes. Includes references to figures and tables.; Page 31 is missing. Pages 37 through 44 do not exist; there is a note about this on page 36. Page 67 also does not exist. -
"Signal distribution in automatic checkout systems."
This paper deals with several selected aspects of the signal distribution in automatic checkout systems. These are: 1) The use of relay matrices as control elements; 2) The inclusion of self-checking capabilities; 3) Problems of systems integration. These aspects are not unique to automatic checkout systems. However, due to the nature of automatic checkout systems as presently being designed around digital circuitry, they find either fuller or different applications than in other types of systems. Also, while they are on the surface somewhat disconnected in nature, they tend to interrelate during the implementation of an automatic checkout system. -
"Sensitivity of rocket engine stability to propellant feed system dynamics."
Because of the increased reliability required of rocket systems in their more recently assigned missions, previously acceptable design features must be reappraised ad refined. In the region of rocket engine system stability, the probles is centered in two areas, the combustor and the propellant feed system The principal interest of this paper lies in the coupling that occurs between the feed system and combustion dynamics, often termed a "buzzing" instability then the dymics are characterized by periodic pressure oscillations in the range of 200 to 1000 cps appearing in the combustion chamber and' the feed system. -
"Selected methods for uprating Saturn vehicles."
This paper will discuss selected methods for increasing the Saturn launch vehicle payload capabilities. These methods involve system changes or additions that give large step performance'increases aver those which can be obtained by product improvements. The selected philosophy of approach and the established designed systems wil1,be described, as well as anticipatedsystem concepts that may be used to increase the Saturn vehicles' capabilities. -

8 x 10 inch black and white photograph of a table reperesenting the chemical composition of alloys M825 and M826. -
"Rocket motor" material list photograph.
8 x 10 inch black and white photograph of a rocket motor material list. The weight of the material is measured in pounds. -
"Saturn data summary handbook."
This handbook provides a technical data summary for the Douglas-produced Saturn S-IV and S-IVB stages of the NASA Apollo Program. Material contained in the S-IVB stage of this handbook includes the S-IB and S-V vehicles. This book will be updated as changes and additional information become available. The appendix contains aerospace fluid characteristics, LOX and LH2 vapor pressure curves and a list of non-standard abbreviations.
