Abstract
An airfoil includes a first end opposite a second end in a spanwise direction. A leading edge extends in the spanwise direction from the first end to the second end and a trailing edge extends in the spanwise direction from the first end to the second end and aft of the leading edge in a chordwise direction. A suction surface extends from the leading edge to the trailing edge and a pressure surface extends from the leading edge to the trailing edge. The airfoil further includes at least one channel with an inlet on a surface of the leading edge and an outlet aft of the leading edge.
