"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. -

Oral History Interview With Steven Hall
Steven Hall was born in a small town in the north central part of Indiana. This town has about a population of 2,000 people. Steven graduated from Eastern High School in 1963, and then he enrolled in Aeronautical/Neurospace Engineering at Purdue University. There, he received his bachelor's degree in 1968. Steven originally became interested in man space-flight when he was just about 10 years old. At this age, he had no clue how he could get involved with the space station, but he knew that he wanted to get involved one day. After he graduated college, he was so ready to work at NASA, that he left his home town immediately to move down to Huntsville, AL to start working. When he began working at the Marshall Space Flight Center, he was shown how Human Factors Engineering worked. One of the first projects that Steven was able to work on was "Skylab" where they built a lot of the equipment that probed how humans responded to space, and how the body changes in space. He also worked on a program to design a vehicle to drive around the surface of the moon.Tags Oral History -

Oral History Interview With George Hamilton
George Hamilton has lived in Huntsville, Alabama all of his life, and his father was a Charter Marshall Member in Huntsville. When he was working, George's father was chosen as a "guinea pig" to go up in the Pregnant Guppy, which was a large, wide-bodied cargo aircraft. Because of George's father's career and interest with NASA, it made George interested in the career as well. George has a lot of family stories like this, which all have inspired him to take on his career that he has now. After high school, George went to The University of South Alabama in Mobile to study Marine Biology. Over the summer he had a change of heart, so he decided to transfer to Auburn University for Mechanical Engineering. After he finished up with his degree, he started working in small, manufacturing spare parts for missiles. After this career, he started to work at Avco Electronics in Huntsville where he worked at the plant on the design side. After this, Avco started looking for people to go overseas on the construction side of the house, so George went overseas with them. Then he came back, got married, and received his Phd in Biomedical Engineering at The University of Alabama in Birmingham.Tags Oral History -

"The production of large tanks for cryogenic fuels"
Archive copy is a poor photocopy. Prepared for presentation at Deutsche Gesellschaft fur Raketentechnik und Raumfahrt. (German Society for Rocket Technology and Astronautics). Given by E. Harpoothian, Chief Engineer, Structures Department, Development Engineering.; Tanks for cryogenic fluids, as used in the Saturn space vehicles, have reached an advanced stage of design and development. Many of the structural features of the NASA/Douglas Saturn tanks, fabricated of 2014-T6 aluminum alloy, were first developed for the booster of the Thor ballistic missile, which later found extensive use in putting space vehicles into orbit. There is a mutual dependence of important factors related to design concepts, selection of materials, processing techniques, and fabrication methods. It is shown that this mutual dependence must be considered if a successful vehicle is to emerge from design and development. Details of vehicle structure, provision for insulation, and manufacturing methods are presented. Criteria for the selection of materials is shown to be dependent on strength, ductility, weldability, toughness, fabricability, behavior at cryogenic temperatures, and on manufacturing methods and inspection techniques. -
Civil War diary of George Washington Harris.
