Wingless Flight: The Lifting Body Story

Wingless Flight tells the story of the most unusual flying machines ever flown, the lifting bodies. It is my story about my friends and colleagues who committed a significant part of their lives in the 1960s and 1970s to prove that the concept was a viable one for use in spacecraft of the future. This story, filled with drama and adventure, is about the twelve-year period from 1963 to 1975 in which eight different lifting-body configurations flew. It is appropriate for me to write the story, since I was the engineer who first presented the idea of flight-testing the concept to others at the NASA Flight Research Center. Over those twelve years, I experienced the story as it unfolded day by day at that remote NASA facility northeast of los Angeles in the bleak Mojave Desert. Benefits from this effort immediately influenced the design and operational concepts of the winged NASA Shuttle Orbiter. However, the full benefits would not be realized until the 1990s when new spacecraft such as the X-33 and X-38 would fully employ the lifting-body concept. A lifting body is basically a wingless vehicle that flies due to the lift generated by the shape of its fuselage. Although both a lifting reentry vehicle and a ballistic capsule had been considered as options during the early stages of NASA's space program, NASA initially opted to go with the capsule. A number of individuals were not content to close the book on the lifting-body concept. Researchers including Alfred Eggers at the NASA Ames Research Center conducted early wind-tunnel experiments, finding that half of a rounded nose-cone shape that was flat on top and rounded on the bottom could generate a lift-to-drag ratio of about 1.5 to 1. Eggers' preliminary design sketch later resembled the basic M2 lifting-body design. At the NASA Langley Research Center, other researchers toyed with their own lifting-body shapes. Meanwhile, some of us aircraft-oriented researchers at the, NASA Flight Research Center at Edwards Air Force Base (AFB) in California were experiencing our own fascination with the lifting-body concept. A model-aircraft builder and private pilot on my own time, I found the lifting-body idea intriguing. I built a model based on Eggers' design, tested it repeatedly, made modifications in its control and balance characteristics along the way, then eventually presented the concept to others at the Center, using a film of its flights that my wife, Donna and I had made with our 8-mm home camera

Wings in Orbit: Scientific and Engineering Legacies of the Space Shuttle, 1971-2010

The Space Shuttle is an engineering marvel perhaps only exceeded by the station itself. The shuttle was based on the technology of the 1960s and early 1970s. It had to overcome significant challenges to make it reusable. Perhaps the greatest challenges were the main engines and the Thermal Protection System. The program has seen terrible tragedy in its 3 decades of operation, yet it has also seen marvelous success. One of the most notable successes is the Hubble Space Telescope, a program that would have been a failure without the shuttle's capability to rendezvous, capture, repair, as well as upgrade. Now Hubble is a shining example of success admired by people around the world. As the program comes to a close, it is important to capture the legacy of the shuttle for future generations. That is what "Wings In Orbit" does for space fans, students, engineers, and scientists. This book, written by the men and women who made the program possible, will serve as an excellent reference for building future space vehicles. We are proud to have played a small part in making it happen. Our journey to document the scientific and engineering accomplishments of this magnificent winged vehicle began with an audacious proposal: to capture the passion of those who devoted their energies to its success while answering the question "What are the most significant accomplishments?" of the longestoperating human spaceflight program in our nation s history. This is intended to be an honest, accurate, and easily understandable account of the research and innovation accomplished during the era

Preaching in the \u27Hear\u27 and Now: Justification, Development, and Assessment of \u27Parabolic Engagement\u27 Pedogogy in French-Speaking Missionary Settings

This thesis argues the utility of ‘parabolic engagement’ method for preachers and listeners in the French Antillean context. The opening chapter defines key terms and clarifies how this imaged sermonic style addresses the listening habits of targeted audiences. It explains that figured delivery is often context-interpretive, involving a more personal, experiential decoding by the listener. Engagement technique increases auditor involvement and creates unique communicative rapport. The chapter points out that the entire experimental process validates the usefulness of the pedagogy. Part One addresses the theological rationale for ‘parabolic engagement’ method. Chapter Two reviews appropriate literature with respect to engagement. Chapter Three argues the biblical basis for creating a method of figured preaching. Chapter Four discusses how precise homiletic situations demand a circumstantial approach to engaging delivery. Part Two attempts to synthesize a broad range of image-creation methodologies and make them suitable for teaching among oral peoples. Chapter Five shows the necessity of a grammar for figured proclamation pedagogy. Chapter Six develops simplified classical methods for finding the illustrative crux of an idea or text. Chapter Seven shows the need to then engage the listener by means of analogous correspondence with the concrete world. Chapter Eight explores how circumstantial factors encourage the transformation of engaging analogies into extended narratives. Part Three validates the thesis within the missionary setting. Chapter Nine describes the suitability of ‘parabolic engagement’ method among Creoles and European French on the island of Martinique. Chapter Ten establishes an experimental design by specifying components, clarifying how the hypotheses were tested, justifying data collection methods, and explaining the use of participatory action research and educational ethnography. Chapter Eleven details the implementation, measurement, and success of engagement strategies. Lastly, Chapter Twelve argues for the utility of ‘parabolic engagement’ and posits generalizations by summarizing the merits, conclusions, and limitations of the model
