RetiredF4 Do we know, how the lift generating capabilities of those airfoils changed in this high AOA regions?
with very high AoA the effect of the profile with his flow is becoming smaler, the center of lift and Cd and Cl approaches the forces of a flat panel with the same AoA.... with an AoA of 90 deg every different foil ends with an center of lift near 50% and an Cd near 1....
