		†The coordinates for these airfoils are not publicly available. Please check the contact on our Airfoil Licensing page. ‡The Applied Aerodynamics Group at the University of Illinois at Urbana- Champaign has put together an excellent database of airfoil shapes.  It includes coordinates and a graphic for each airfoil. They make them available on this website.
