Recent readings have shown the benefits of "boundary layer tripping devices" or vortex generators for reducing drag and maintaining attached air flow at higher angles of attack.
It seems these generators effectively increase the width of the wing by creating an energized "fence", which further deflects the free air stream, almost acting as a lubricant to reduce friction drag on the surface of the wing and increasing the "bend" of the airstream, thereby increasing lift.
But generating these vortices comes at the expense of increased drag to create them, though they (and slats) could be made to be retractable.
Is there a clear advantage to either a thick laminar wing or a thinner one with vortex generators? The Reynolds number for the application would be around 200,000 to 500,000.
