The patent relates to a lifting airfoil which has the capability of exhibiting a coanda profile, or blunt trailing edge for low speed landings capability, and a blown flap or jet flap for high speed transonic operation. The airfoil may be a supercritical type employing a flap which can be rotated to combine with the airfoil to produce a coanda profile or which can be used as a blown flap at transonic speeds when combined with a high velocity blowing jet over the flap. In addition, the supercritical airfoil can include a slot in the underside of the foil for flowing a jet flap in lieu of the blown flap.
