On laminar flow and supercritical wings, you'll see "the circle" continuing on top, while the airflow line-up happens through an S-curve on the underside....

Hi Euromodder,
Yes, the bottom side of this airfoil is designed to create more lift. I'm after minimizing air drag, so the bottom "S-curve" may not apply in our road-going designs.
I still think that the streamlining airfoil shape from 70% to 100% needs some "adjustment".
Your airfoil still curves even if it is slightly, over that last portion on the top side of the wing.
