A free-streamline airfoil includes a lower surface which is flat or contoured, and an upper surface that is curved or made of discrete flat elements approximating a curved surface, the upper surface presenting a cavity, a cavity width in an airfoil chordwise direction shorter than the airfoil chord, a position and depth of the cavity triggering a turbulent flow over the airfoil's suction side while preserving the airfoil physical integrity.
