One of the new approaches in full-scale soaring is to use suction to manage the airfoil's boundary layer (eg, drawing air into the wing near/before the separation point). There is some research being done at Delft right now if I remember correctly.

Blowing air to trip the airflow early has been done for 20 years. Acoustics have also been tried to manage flow.

Not sure how laminar the state-of-the-art F3B airfoils are but I would imagine well past the aileron/flap hinge line. Would be interesting to see what some of folks with aero/fluids expertise have to say.

Interesting topic,

Mike
