NASA VARIABLE-GEOMETRY RESEARCH

Abstract

The past, present, and probable future research activities of NASA with respect to applications of variable geometry are outlined. A general discussion is given of the reasons for considering variable geometry. Past developments are summarized to show how they have resulted in increased operational flexibility of aircraft. Emphasis is placed on the variable-sweep program. The historical aspects and objectives of this activity are described briefly. The various approaches that have been investigated, along with some of their advantages, are described. The scope of the NASA program with respect to configurations, mission studies, structures, mechanisms, flutter, and piloting problems is outlined. The report concludes with a brief expression of thoughts on possible future applications of variable geometry to both aeronautics and space programs.
