Abstract
A nozzle in which an airfoil includes a pressure surface and a suction surface that join at substantially opposing chordal ends of the airfoil to form a leading edge of the airfoil and a trailing edge of the airfoil. A trailing edge passage is defined through the airfoil through which coolant flows. The trailing edge passage is proximate to the trailing edge of the airfoil and has a contoured shape that conforms to that of the trailing edge.
