STATOR BLADE AEROFOIL PROFILE FOR COMPRESSOR

PROBLEM TO BE SOLVED: To provide a stationary blade aerofoil section for a compressor solving the problem that an aerofoil section of a stationary blade for a compressor need to be what optimizes interaction among other stages of the compressor, achieves aerodynamic efficiency, and optimizes aerodynamic life target. SOLUTION: An eleventh stage 12 stator vanes 14 for a compressor 10 comprise airfoil profiles 20 substantially in accordance with Cartesian coordinate values of X, Y and Z set forth in inches in Table I (not indicated), wherein the Z coordinate values are perpendicular distances from planes normal to a radius from the compressor centerline and containing the X and Y values with the Z value commencing at zero in the X, Y plane at a radial aerodynamic section of the airfoil. X and Y are coordinate values defining the airfoil profile at each distance Z. The X, Y and Z values may be scaled to provide a scaled-up or scaled-down airfoil section for each stator vane.
