The National Research Council's Aeronautics and Space Engineering Board conducted a workshop in January 1984 to project what the state of knowledge of aeronautical technology could be in the year 2000 if necessary supporting resources were made available. Eight panels were organized to assess possibilities in the areas of: (1) aerodynamics; (2) propulsion; (3) structures; (4) materials; (5) guidance, navigation and control; (6) computer and information technology; (7) human factors; and (8) systems integration. Participating in these panels were experts from academia, industry, and government. Projections were made that would serve as a base for planning future research and facilities and also as an insight base on the state of the art in aeronautical technology for civil and military planners of air vehicles and systems. Proceedings from this study are arranged into three sections: (1) summaries of the principal findings of each panel; (2) individual panel reports; and (3) an appendix containing panel recommendations regarding requirements for supporting research and facilities. A bibliography and glossary of aeronautical terms and codes are also included. (ML)
