Designed by Wernher von Braun and Arthur Rudolph at NASA¿s Marshall Space Flight Center, the Saturn V rocket represents the pinnacle of 20th Century technological achievement. The only launch vehicle in history to transport astronauts beyond Low Earth Orbit, the Saturn V delivered 24 men to the moon. To this day it holds records as the tallest (363 feet), heaviest (nearly 7 million lbs.) and most powerful (over 7.6 million pounds-force of thrust) launch vehicle ever produced. It also remains one of the most reliable, achieving 12 successful launches with one partial failure ¿ the unmanned Apollo 6 which suffered vibration damage on lift-off, resulting in a sub-standard orbit.The Saturn series of rockets resulted from Von Braun¿s work on the German V-2 and Jupiter series rockets. The Saturn I, a 2-stage liquid-fueled rocket, flew ten times between 1961 and 1965. A uprated version the 1B carried the first crewed Apollo flight into orbit in 1968. The Saturn V, which first flew in 1967, was a three-stage rocket. The first stage, which burned RP-1 and LOX, consisted of five F-1 engines. The second stage used five J-2 engines which burned LOX and liquid hydrogen (LH2). The third stage, based on the second stage of the Saturn 1B, carried a single J-2. The Saturn V could carry up to 262,000 pounds to Low Earth Orbit and more critically, 100,000 pounds to the Moon.Created by NASA as a single-source reference as to the characteristics and functions of the Saturn V, this manual was standard issue to the astronauts of the Apollo and Skylab eras. It contains information about the Saturn Vsystem, range safety and instrumentation, monitoring and control, prelaunch events, and pogo oscillations. It provides a fascinating overview of the rocket that made ¿one giant leap for mankind¿ possible.

This manual was written for design engineers to enable them to choose appropriate fasteners for their designs. Subject matter includes fastener material selection, platings, lubricants, corrosion, locking methods, washers, inserts, thread types and classes, fatigue loading, and fastener torque. A section on design criteria covers the derivation of torque formulas, loads on a fastener group, combining simultaneous shear and tension loads, pullout load for tapped holes, grip length, head styles, and fastener strengths. The second half of this manual presents general guidelines and selection criteria for rivets and lockbolts. To the casual observer the selection of bolts, nuts, and rivets for a design should be a simple task. In reality it is a difficult task, requiring careful consideration of temperature, corrosion, vibration, fatigue, initial preload, and many other factors. The intent of this manual is to present enough data on bolt and rivet materials, finishes, torques, and thread lubricants to enable a designer to make a sensible selection for a particular design. Locknuts, washers, locking methods, inserts, rivets, and tapped holes are also covered.

When Francis Bacon wrote the New Atlantis in the early 17th century, he envisioned a state-supported research institution in which knowledge could be applied to 'enlarge the bounds of Human Empire, to the effecting of all things possible." Among the research facilities to increase the protection and material comforts of the inhabitants of his imaginary island, Bacon imagined an Engine House to study all types of motion, including flight. National aeronautical research laboratories in Europe and the United States in the early 20th century reflected Bacon's vision of science applied to the practical problems of flight. Commitment to innovation accompanied Bacon's belief in progress. His utopia honored inventors, not politicians or academics.In 1941 the same commitment to innovation and industrial progress won federal funding for a laboratory in Cleveland, Ohio. Local and national leaders expected the new laboratory to promote innovations in aircraft engine technology to help win the war against Germany. Contributions to the development of superior engines for military and passenger aircraft after World War II justified the large federal investment in research facilities and personnel. Today this laboratory is the NASA Lewis Research Center. In contrast to the isolation of the ideal research institution of Bacon's vision, Lewis took shape in a flesh-and-blood world of personalities, national security concerns, and postwar capitalism.Two transitions, both precipitated by advances in propulsion technology, provide the structure for my history: the revolution in jet propulsion during World War II, and the launch of Sputnik in October 1957. Each had significant national political, military, and economic repercussions. Each forced the laboratory to restructure its research program and to redefine its relationships with its three constituencies--the military, industry, and academia. Within this framework I have distinguished one theme that recurs throughout the laboratory's history--the tension between fundamental or basic research and development. In the process of writing my history I found that these terms could not be defined in any absolute sense. Their meaning is enmeshed in the history of Lewis, and the definitions of research and development changed as Lewis evolved. As an institution, Lewis engaged in a continuing reevaluation of its role within the American propulsion community and, after the formation of NASA in 1958, within a vastly expanded federal bureaucracy.

This book introduces the general field of Sun-weather/climate relationships, that is, apparent weather and climate responses to solar activity, and provides theoretical and experimental suggestions for further research to identify and investigate the unknown causal mechanisms. It is directed to researchers active in the atmospheric and space sciences who wish to expand their background for meeting the challenge of this newly emerging field and to students who desire a general background in the several disciplinary areas of the field. In the 200-year history of Sun-weather studies, a large body of information has accumulated. Even though the reported results have sometimes been confused, disjointed, and contradictory, there has emerged a growing belief that there are connections between changes on the Sun and changes in the lower atmosphere. There is, however, a deplorable lack of acceptable physical mechanisms to explain those probable connections, and this has prevented widespread acceptance of the reality of solar activity effects on the weather and climate. The discovery of viable mechanisms will strengthen the scientific basis of Sun-weather relationships and may lead to improved predictions of weather and climate. It is obvious that improved predictions would have a profound impact on several crucial societal problems, especially in the areas of global food production and utilization of solar energy for man's needs. This book reviews the correlations between solar activity and weather and climate reported in historical and contemporary literature, addresses the physical linking mechanisms, and suggests experimental concepts for future investigations of such mechanisms. It is our intention to fill a gap in the literature by combining a review of the nature and quality of existing correlations with the basic physics underlying the various scientific disciplines required to pursue studies of physical linking mechanisms. We emphasize the multidisciplinary nature of the subject while providing a basic background in each of the various areas thought to play a role in coupling processes. In following this approach, we hope to acquaint meteorologists with solar and geophysical phenomena, solar physicists with terrestrial atmospheric processes, and so on, thereby stimulating the cross fertilization we believe is necessary for further progress in Sun-weather studies.
