Investigation of the Applicability of the Free-wing Principle to Light, General Aviation Aircraft

Richard F. Porter, R. G. Luce, J. H. Brown

Abstract

Gust-alleviation benefits for aircraft employing an unconventional wing, free to pivot about a spanwise axis forward of its aerodynamic center and subject only to aerodynamic pitching moments imposed by lift and drag forces and a trailing-edge control surface are reviewed.
