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
