- 1. An airfoil for a stator vane having an uncoated profile substantially in accordance with Cartesian coordinate values of X, Y and Z set forth in Table I carried only to four decimal places wherein Z is a distance from a platform on which the airfoil is mounted and X and Y are coordinates defining the profile at each distance Z from the platform.
- 6. A compressor comprising at least one row of stator vanes wherein each of said stator vanes comprises a base and an airfoil extending therefrom, at least one of said airfoils having an airfoil shape, said airfoil shape having a nominal profile substantially in accordance with Cartesian coordinate values of X, Y and Z set forth in Table I carried only to three decimal places wherein Z is a distance from an upper surface of said base from which said airfoil extends and X and Y are coordinates defining the profile at each distance Z from said base.
- 14. A stator assembly comprising at least one stator vane comprising a base and an airfoil extending from said base, wherein said airfoil comprises an uncoated profile substantially in accordance with Cartesian coordinate values of X, Y and Z set forth in Table I carried only to three decimal places wherein Z is a distance from an upper surface of said from which said airfoil extends and X and Y are coordinates defining the profile at each distance Z from said base, said profile scalable by a predetermined constant n and manufacturable to a predetermined manufacturing tolerance.
