  • Stator vane assembly for a gas turbine engine
    Patent number: 7025563
    Abstract: A low-pressure compressor exit stator assembly for a gas turbine includes a multiple of vanes mounted between a full hoop outer shroud and an inner shroud. The outer shroud and inner shroud are mounted to the intermediate case structure. A seal is located between the outer shroud and a bleed duct structure to accommodate thermal growth mismatch.

  • Stator assembly for a rotary machine and clip member for a stator assembly
    Patent number: 6409472
    Abstract: A stator assembly for a rotary machine having a shroud for a stator vane is disclosed. Various construction details are developed which limit movement of the stator vane into the flowpath by reason of the stator vane being restrained by the shroud. In one particular embodiment, a clip member extends through an opening in the tip of the vane and is disposed at a location adjacent a nonflowpath surface of the shroud to restrain the tip of the vane against inward movement through the shroud.
