Abstract
The disclosure provides a nozzle adapted for placement within a flowpath of a turbomachine. The nozzle includes an airfoil having a suction side; a pressure side opposing the suction side; a leading edge between the pressure side and the suction side; a trailing edge opposing the leading edge and between the pressure side and the suction side; a root region at a first radial end; a tip region at a second radial end opposite the first radial end; and a midspan region between the root region and the tip region. An endwall is connected with the root region or the tip region of the airfoil along the suction side, the pressure side, the trailing edge, and the leading edge. The trailing edge of the airfoil has an elliptical shape having a nominal profile substantially in accordance with Cartesian coordinate values of X, Y, and Z set forth in TABLE I.
