<p>An airfoil is provided. The airfoil (10) includes an airfoil blade (20). The airfoil blade (20) has a trailing edge (34), a pressure sidewall (40) and a suction sidewall (38), where a portion of the airfoil blade (20) has a widest cross section when measured between the suction sidewall (38) and the pressure sidewall (40). A plenum (36) is located along the widest cross section. At least one passageway (42) extends in an axial direction from the plenum (36) and terminates at the trailing edge (34). The at least one passageway (42) is in fluid communication with and receives a flow from the plenum (36).</p> |
