Abstract: A gap closing wearliner may comprise a first liner portion disposed within a groove of a compressor vane case, the first liner portion having first surface parallel to an inner face of the groove and a second surface parallel a lower face of the groove, the first liner portion formed to a contour of the groove and configured to receive a tongue of a pedestal having a vane, a gap between the first surface of the first liner portion and the tongue, and a high Coefficient of Thermal Expansion (CTE) material. The gap closing wearliner may further comprise a second liner portion disposed within the groove of the compressor vane case, formed to the contour of the groove, and configured to receive the tongue of the pedestal.

Abstract: A liner assembly for placement between a mounting foot of a platform and a case of a gas turbine engine includes first and second annular liner segments configured to move independently of each other. The first annular liner segment is configured to be mounted on at least a portion of a radially outward surface of the mounting foot. The first annular liner segment includes a first flat portion and a first curved portion extending from a first end of the first annular liner segment. The second annular liner segment is configured to be mounted on at least a portion of a radially inward surface of the mounting foot. The second annular liner segment includes a second flat portion and a second curved portion extending from a first end of the second annular liner segment.

Abstract: A stator assembly for a stator of a gas turbine engine is provided. The stator assembly having: a shroud defining a cavity; a plurality of inserts located within the cavity, each of the plurality of inserts defining a cavity; a plurality of vanes secured to the shroud, wherein each of the plurality of vanes has a tab portion located in the cavity of the shroud; and a rubber material disposed in the cavity of the shroud, the rubber material securing the tab portion of each of the plurality of vanes to the shroud.

Abstract: A vane assembly may include a vane comprised of a composite material. An outer shroud segment may be disposed at radially outer end of the vane. An inner shroud may define an aperture. A radially inner end of the vane may be disposed within the aperture.

Abstract: A stator assembly for a gas turbine engine includes an arcuate shroud including a shroud pocket, the shroud pocket having a shroud slot extending therethrough. A stator vane is insertable into the shroud pocket and includes a vane slot extending therethrough. A strap extends through the shroud slot and the vane slot to retain the vane to the shroud. A gas turbine engine includes a combustor and a stator and case assembly in in fluid communication with the combustor. The stator and case assembly includes a case defining a working fluid flowpath for the gas turbine engine and a stator assembly secured at the case.

Abstract: An assembly for rotational equipment with an axial centerline. The assembly includes a first component and a second component. Each of the components extends circumferentially around and axially along the centerline. The first component includes a flange and a lug aperture extending axially through the flange. The second component includes a mount base and a bayoneted lug on the mount base. The mount base is configured to axially engage the flange where the bayoneted lug extends through the lug aperture. A fastener secures the components together. The fastener projects axially into a fastener aperture in the mount base for an axial length that is less than or equal to an axial length of the bayoneted lug.

Abstract: A stator assembly for a gas turbine engine includes an annular outer shroud, an annular inner shroud radially spaced from the outer shroud and a plurality of stator vanes extending from the outer shroud to the inner shroud. A volume of potting is located at the inner shroud and at the outer shroud to retain the plurality of stator vanes thereat. A stator and case assembly for a gas turbine engine includes a case defining a working fluid flowpath for the gas turbine engine and a stator assembly located at the case. The stator assembly includes an annular outer shroud secured to the case, an annular inner shroud secured to the case and a plurality of stator vanes extending from the outer to the inner shroud. A volume of potting is located at the inner shroud and at the outer shroud to retain the plurality of stator vanes thereat.

Abstract: A stator includes a plurality of stator vanes and a shroud operably connected to the stator vanes. The shroud includes one or more positioning tabs configured to engage one or more corresponding alignment features of a mating component to radially position the shroud at the mating component, the one or more shroud positioning tabs position the outer shroud to define a radial tip clearance between an outer shroud and an adjacent rotor of the gas turbine engine. A gas turbine engine includes a stator and case assembly in fluid communication with a combustor. The stator and case assembly includes a stator located at a case. The stator has a plurality of stator vanes and a shroud including one or more positioning tabs configured to engage one or more corresponding case alignment features to radially position the shroud at the case.
