But mostly I think it's about looks.
I'm not sure that this is right. An aerodynamic profile can maintain laminar flow and inhibit initiation of turbulent flow. But once the flow is turbulent, the game is up. I haven't seen any data to suggest that an aerodynamic profile can actually take turbulent flow and force it to become laminar. If there are any aeronautical engineers peering at this thread, maybe they could clarify?
