The central task of a 1980 workshop on the role of the National Aeronautics and Space Administration (NASA) in aeronautics was to examine the relationship of NASA's research capabilities to the state of U.S. aviation and to make recommendations about NASA's future role in aeronautics. Following an introduction, findings and recommendations of the Panel on Rotorcraft are presented under the categories: (1) Status and Dimension of the Rotorcraft Sector of the Aviation Community; (2) Maintaining a Superior Rotorcraft Capability; (3) Rotorcraft Research and Technology Needs; (4) Evolution of NASA's Current Role in Rotorcraft Technology; (5) NASA's Role in the Future - 1980 and Beyond; and (6) Conclusions and Recommendations. Definitions of roles and disciplines are included in an appendix. (Author/DS)
