Claim 13:
14. A turbine comprising a plurality of nozzle structures, each of the plurality of nozzle structures comprising:
a nozzle structure within a flowpath of the turbine, the nozzle structure comprising:
an airfoil including: 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; and
an endwall 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,
wherein 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, wherein the Cartesian coordinate values are non-dimensional values of from 0% to 100% convertible to distances by multiplying values by a height of the airfoil expressed in units of distance, and wherein X and Y values connected by arcs define airfoil profile sections at each distance Z along at least a portion of the airfoil, the profile sections at the Z distances being joined with each other to form the nominal profile.
