Abstract: A turbine shroud for incorporation in a turbine of a gas turbine engine has a plurality of butted shroud segments circumferentially arrayed to form a ring. Each of the shroud segments has an arcuate main shroud body portion, a radially inward extending annular flange attached to a first end of the main body portion, and a radially outward extending flange with a plurality of mounting apertures attached to a second end of the main shroud body portion. A first mounting aperture is sized smaller than an adjacent second mounting aperture in the radially outward extending flange.

Abstract: An alignment tie rod device for connecting multiple components from generally opposite directions includes a shaft extending along a centerline. A first structure of the device includes opposing first and second rims and a base portion spanning between the rims. The base portion and rims define a channel that extends substantially normal to the centerline. A hole in the base portion is centered between the rims and communicates through the base portion for receipt of the shaft. An anti-rotation feature disposed operably within the channel is rigidly engaged to and projects radially outward from the shaft in diametrically opposed direction. The feature has diametrically opposite, arcuate, edges each having a radius of curvature that is substantially greater than a distance measured between the rims.

Abstract: A vane seal system includes a non-rotatable vane segment that has an airfoil with a pocket at one end thereof. The pocket spans in an axial direction between forward and trailing sides, with respect to the airfoil, and in a lateral direction between open lateral sides. A seal member extends in the pocket. The seal member includes a seal element and at least one spring portion that is configured to positively locate the seal member in the axial direction in the pocket. A method for positioning the seal member in a vane seal system includes positively locating the seal member in the axial direction in the pocket using the spring portion.

Abstract: The present disclosure relates generally to a sliding seal between two components. The sliding seal includes a carrier having one or more cavities formed therein. The one or more carriers may contain wave springs and/or compliant seals therein. Various embodiments provide loading of the seal in both the axial and radial directions, regardless of whether a pressure differential exists across the seal, by means of springs and/or ramped surfaces. Other combinations of carrier, wave springs, and compliant seals are also disclosed.
