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.
Claims22
An airfoil comprising:
- a first end opposite a second end in a spanwise direction;
- a leading edge extending in the spanwise direction from the first end to the second end;
- a trailing edge extending 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 extending from the leading edge to the trailing edge;
- a pressure surface extending from the leading edge to the trailing edge;
- and
- a plurality of channels, wherein each channel of the plurality of channels comprises:
- an inlet proximate the leading edge;
- and
- an outlet proximate the trailing edge;
- and
- a tube on the suction surface or the pressure surface of the airfoil, and wherein the tube extends from the inlet to the outlet.
