  • Patent number: 10415593
    Abstract: A system is provided, including an airfoil. The airfoil includes a first suction portion of a nominal airfoil profile substantially in accordance with Cartesian coordinate values of X, Y, and Z of a suction side as set forth in TABLE I to a maximum of three decimal places, wherein the X and Y values of the suction side are coordinate values that couple together to define suction side sections of the first suction portion of the nominal airfoil profile at each Z coordinate value, the suction side sections of the first suction portion of the nominal airfoil profile are coupled together to define the first suction portion, the airfoil includes an airfoil length along a Z axis, the first suction portion comprises a first portion length along the Z axis, the first portion length is less than or equal to the airfoil length, and the Cartesian coordinate values of X, Y, and Z are non-dimensional values convertible to dimensional distances.

  • Publication number: 20120134783
    Abstract: A compressor includes a first stage of stator vanes having a first position and a second stage of stator vanes downstream from the first stage of stator vanes having a second position. A first actuator is engaged with the first stage of stator vanes, and a second actuator is engaged with the second stage of stator vanes. A method for operating a compressor includes adjusting a first position of a first plurality of stator vanes and adjusting a second position of a second plurality of stator vanes separately from the first position of the first plurality of stator vanes.
