  • Patent number: 8668593
    Abstract: A shaft includes a shoulder that transitions the shaft from a first diameter to a second diameter. The shaft includes a groove that is disposed immediately adjacent to and/or is formed in an inner radial portion of the shoulder. The groove acts to produce uniform deflection of the shoulder in an axial direction with respect to a centerline axis of the shaft.
    Type: Grant

  • Patent number: 8579591
    Abstract: A compressor impeller includes a hub, main blades and splitter blades. The main blades are equally spaced around the circumference of the hub. Each splitter blade is equally spaced between two adjacent main blades. Each main blade and splitter blade has suction and pressure surfaces formed in substantial compliance with normalized Cartesian coordinate values of X, Y, and Z set forth in Tables 1-4. When connected by smooth, continuing arcs, the normalized Cartesian coordinates form complete main blade and splitter blade shapes that are substantially matched by the main blade and splitter blade shapes of the compressor impeller.
    Type: Grant

  • Patent number: 8511971
    Abstract: A compressor shroud for containing fragments of a compressor impeller and a turbine wheel within a gas turbine engine. The compressor shroud includes a compressor containment section, a turbine containment section, and a containment continuity section. The containment continuity section connects the compressor containment section and the turbine containment section to form a one-piece part.
