"Ground testing at MSFC : research achievements review series no 9"

In 1955, the team which has become the Marshall Space Flight Center (MSFC) began to organize a research program within its various laboratories and offices. The purpose of the program was two-fold: first, to support existing development projects by research studies and second, to prepare future development projects by advancing the state of the art of rockets and space flight. Funding for this program came from the Army, Air Force, and Advanced Research Projects Agency. The effort during the first year was modest and involved relatively few tasks. The communication of results was, therefore, comparatively easy.; Pages of handwritten notes on yellow legal paper. There is also a 3 x 5 inch card with this information. Article reference for Saturn History Files: Schuler, Albert E. (NASA-MSFC) Research and development in instrumentation for static testing.

"Groundbreaking Ceremony: Constitution Hall Park."

Speakers included James Record, Frances Roberts, and Huntsville Mayor Joe Davis, with an invocation by Rev. Donald L. Bailey and a benediction by Rev. Lee Hudson. The program includes a map of Constitution Hall Park.

"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.

"Helium Utilization in the Apollo/Saturn V Vehicle."

Helium is used extensively throughout the Apollo/Saturn V space vehicle for a number of applications. The welding use is not discussed since it is a special topic. In the first stage (S-IC), helium is used for liquid oxygen tank pressurization during vehicle checkout and launch.
