Abstract
The supercritical profile has an upper surface whose curvature has two minima, one in front of the mid-chord station, the other one rather close to the trailing edge and having a lower value than the first one. The curvature of the lower surface remains larger beyond the mid-chord station, changes sign and increases to a pronounced maximum not far from the second curvature minimum of the upper surface, and drops to zero at the trailing edge.
