Abstract
Passive lift enhancement for flexible nonslender delta wings has been demonstrated as a potential method for the control of vortex-dominated wing flows. Physical mechanisms of lift enhancement and the effect of important variables are discussed. Lift enhancement for flexible wings with low/moderate sweep is a very complex phenomenon, involving self-induced antisymmetric vibrations of leading edges, spanwise camber effect due to the large time-averaged deflection, shear layer instabilities, reattachment, increased mean vorticity flux and circulation, re-formation of the leading edge vortices, possible enhancement of streamwise pressure gradient, and the effects of frequency and edge velocity.
