Flight Research at NASA Langley Research Center by Mark A. Chambers Pdf
Following the creation of the National Advisory Committee for Aeronautics in 1915, a unique flight research operations division was established at the nation's first civilian aeronautics research laboratory, the Langley Memorial Aeronautical Laboratory. Langley flight research personnel helped the nation's aircraft industry bloom during the Golden Era of aviation throughout the 1920s and 1930s. Langley's flight research then helped win World War II with performance-enhancing modifications to new aircraft. During the cold war, Langley helped the country maintain an edge in aeronautics over its Warsaw Pact rivals. When the space race began, the National Aeronautics and Space Administration (NASA) was created in 1958 and Langley's pilots were instrumental in training astronauts. In addition to advancing rotorcraft during the 1960s and 1970s, Langley research pioneered a multitude of military and civil Vertical Short Takeoff and Landing (V/STOL) concepts. During the 1970s, 1980s, and 1990s, Langley research developed advancements in general and commercial aviation technologies.

This NASA publication provides an overview of the topic of revolutionary research in aeronautics at Langley, including many examples of research efforts that offer significant potential benefits, but have not yet been applied. The discussion also includes an overview of how innovation and creativity is stimulated within the Center, and a perspective on the future of innovation. The documentation of this topic, especially the scope and experiences of the example research activities covered, is intended to provide background information for future researchers. Innovation: The Seed Corn of Tomorrow * Selected Examples of Langley's Research On Revolutionary Advanced Concepts * Supersonic Civil Aircraft * The Blended Wing Body * Synthetic Vision * Laminar-Flow Control * Upper Surface Blowing * Control of Aeroelastic Response * The Joined Wing * The Vortex Flap * Innovative Control Effectors * Personal Air Transportation Concepts * The Future of Innovation: Priming the Pump The objective of this publication is to discuss the importance of innovation and the role of revolutionary advanced concepts within the aeronautics research community, and to provide information on typical advanced research projects conducted by Langley and its partners on topics that have not yet been applied by the military or civil aviation industry to production aircraft. Detailed information is first provided to describe each advanced concept, the projected benefits that could be provided if the technology is applied, and the challenges faced by the NASA research team to reduce the risk of application. Next, descriptions of specific research activities on the concepts identify the key projects, accomplishments, personnel, and facilities involved in the development of each concept. Finally, perspectives are provided on the current status of the subject concepts, including discussions of factors or future events that might intensify interest in their use for future applications. Many of the concepts described herein are subjects of ongoing NASA research thrusts, for which significant technical challenges are in the process of being addressed. This document is intended to serve several purposes. As a source of collated information on revolutionary concepts, it will serve as a key reference for readers wishing to grasp the underlying principles and challenges related to specific revolutionary concepts. Hopefully, such information will provide valuable background that can serve as starting knowledge bases for future research efforts and minimize the so-called "reinvention of the wheel" syndrome. More importantly, the information identifies major obstacles to advanced aeronautics technology, thereby providing a sensitivity for multi-faceted research projects to ensure a higher likelihood of application. A definition of current barriers to application is extremely valuable for use in the future, when new breakthroughs in various technical disciplines may eliminate or minimize some of the critical barriers that have traditionally blocked the application of some of these specific revolutionary concepts. Finally, a review of the material will hopefully inspire the nontechnical (as well as technical) communities that aeronautics is not a "mature science" and that considerable opportunities exist to revolutionize the future. The written material has been prepared for a broad audience and does not presume any significant technical expertise. Hopefully, it will provide informative and interesting overviews for researchers engaged in aeronautics activities, internal NASA policy makers, national policy makers, NASA stakeholders, the media and the general public.
Journey Into Space Research by National Aeronautics Administration,William H. Phillips Pdf
Space flight has long been a subject of interest both to scientists and to the general public. Science fiction became popular with the works of Jules Verne, whose fanciful stories of space exploits inspired many later science fiction publications. These stories were usually not based on valid science and technology or they were ahead of the developments that might have made them possible. These works, however, served to stimulate thought on space flight for many years. Some groups, such as the British Interplanetary Society, made serious studies of the requirements for space flight. These efforts failed to lead to practical developments because of lack of financial support or interest from governmental organizations or from the public. These early studies had little effect on actual developments in the space program because, with greater support and larger numbers of investigators, the results were quickly rediscovered and not until later was it found that some important results had been worked out previously. Studies of the possible military applications of space flight were started by military organizations in the United States about 1950, but these studies were classified secret. Many were unaware of any activity in this field until the nation was startled by the Russian launching of Sputnik. The last chapter of the preceding volume on the history of the author's work at Langley describes how the nation was galvanized into action and started a national space program. These developments are described in more detail in the book Spaceflight Revolution. The advent of the space program was a welcome event to many of the research groups at Langley. One reason for this attitude was that aeronautical research had reached a plateau at this time. Many of the research contributions of Langley and other National Advisory Committee for Aeronautics (NACA) centers had reached fruition in the design and production of advanced airplanes. These airplanes included jet bombers and transports, and supersonic fighter airplanes. Research and design work on the supersonic transports, the British Concorde and the Russian TU144, had progressed to a point that construction could proceed with some assurance of success. No really revolutionary advances for atmospheric aircraft were envisioned at that time or have occurred in the ensuing years. Some of the wind-tunnel organizations, however, expressed concern that their work might be cut back or otherwise affected by the emphasis on space research. In the case of the author's work and that of the Flight Research Division, another event occurred that required a change in direction. A NACA Headquarters edict, published in 1958, stated that no further testing of high-speed airplanes would be done at Langley. All future flight research on such airplanes was to be done at the Edwards Air Force Base in California (now called the Dryden Flight Research Center).

Recapturing NASA's Aeronautics Flight Research Capabilities by National Research Council,Division on Engineering and Physical Sciences,Aeronautics and Space Engineering Board,Committee to Assess NASA's Aeronautics Flight Research Capabilities Pdf
In the five decades since NASA was created, the agency has sustained its legacy from the National Advisory Committee on Aeronautics (NACA) in playing a major role in U.S. aeronautics research and has contributed substantially to United States preeminence in civil and military aviation. This preeminence has contributed significantly to the overall economy and balance of trade of the United States through the sales of aircraft throughout the world. NASA's contributions have included advanced flight control systems, de-icing devices, thrust-vectoring systems, wing fuselage drag reduction configurations, aircraft noise reduction, advanced transonic airfoil and winglet designs, and flight systems. Each of these contributions was successfully demonstrated through NASA flight research programs. Equally important, the aircraft industry would not have adopted these and similar advances without NASA flight demonstration on full-scale aircraft flying in an environment identical to that which the aircraft are to operate-in other words, flight research. Flight research is a tool, not a conclusion. It often informs simulation and modeling and wind tunnel testing. Aeronautics research does not follow a linear path from simulation to wind tunnels to flying an aircraft. The loss of flight research capabilities at NASA has therefore hindered the agency's ability to make progress throughout its aeronautics program by removing a primary tool for research. Recapturing NASA's Aeronautics Flight Research Capabilities discusses the motivation for NASA to pursue flight research, addressing the aspects of the committee's task such as identifying the challenges where research program success can be achieved most effectively through flight research. The report contains three case studies chosen to illustrate the state of NASA ARMD. These include the ERA program and the Fundamental Research Program's hypersonics and supersonics projects. Following these case studies, the report describes issues with the NASA ARMD organization and management and offers solutions. In addition, the chapter discusses current impediments to progress, including demonstrating relevancy to stakeholders, leadership, and the lack of focus relative to available resources. Recapturing NASA's Aeronautics Flight Research Capabilities concludes that the type and sophistication of flight research currently being conducted by NASA today is relatively low and that the agency's overall progress in aeronautics is severely constrained by its inability to actually advance its research projects to the flight research stage, a step that is vital to bridging the confidence gap. NASA has spent much effort protecting existing research projects conducted at low levels, but it has not been able to pursue most of these projects to the point where they actually produce anything useful. Without the ability to actually take flight, NASA's aeronautics research cannot progress, cannot make new discoveries, and cannot contribute to U.S. aerospace preeminence.
