Abstract: A shroud assembly for a turbine engine comprises a plurality of circumferentially arranged shroud segments, each terminating in circumferentially spaced first and second shiplap elements, where the first shiplap element of one shroud segment can overlap the second shiplap element of an adjacent shroud segment.

Abstract: An apparatus for a shroud assembly for a turbine engine and a method of manufacturing such can include the shroud assembly having one or more shroud segments having an inner face in a circumferential organization around a rotating blade assembly. A near wall cooling passage can be provided in the shroud assembly to cool the inner face of the shroud. The near wall cooling passage can exhaust to a purge cavity, a split line, or at the inner face.

Abstract: An airfoil profile-shaped seal is disposable between an inside surface of a hollow airfoil body and a seal support. The seal includes an elongated member defining a generally closed curve having a generally straight portion, a generally curved portion, and having a solid cross-section across and along the length of the elongated member. When the seal is disposed in an airfoil profile-shaped groove of a seal support adjacent to the inner surface of the hollow airfoil body, and a fluid pressure on one side of the seal is greater than a fluid pressure on the other side of the seal, portions of the seal engage the inner surface of the hollow airfoil body and a surface of the groove to form a seal to inhibit leakage of fluid from the one side to the other side.

Abstract: A stator component of a turbine engine having an airfoil defining a radial cooling channel, the airfoil having an airfoil outer surface and an airfoil inner surface. The airfoil outer surface defines a leading edge portion, a trailing edge portion, a pressure side wall, and a suction side wall. The airfoil inner surface defines a series of alternating peaks and valleys in the leading edge portion such that the airfoil has a varying cross-sectional thickness defined between the airfoil inner surface and the airfoil outer surface in the leading edge portion. A strut is disposed within the radial cooling channel and defines an inner radial cooling passage. The strut has an outer surface that defines a plurality of apertures that provide for fluid communication from the inner radial cooling passage to a radial cooling gap defined between the airfoil inner surface and the outer surface of the strut.

Abstract: A component for a gas turbine engine includes a first surface and a second surface. The component additionally includes one or more layers of ceramic matrix composite material extending between the first and second surfaces. A thermal void extends between a first end and a second end. The second end of the thermal void is a terminal end embedded in the component between the first and second surfaces.

Abstract: An engine component for a gas turbine engine generating hot combustion gas flow is provided. The engine component can include a substrate constructed from a CMC material and having a hot surface facing the hot combustion gas flow and a cooling surface facing a cooling fluid flow. The hot combustion gas flow defines an upstream direction and a downstream direction relative to the hot surface. The substrate also defines a film hole extending through the substrate and having an inlet provided on the cooling surface, an outlet provided on the hot surface, and a passage connecting the inlet and the outlet. The passage comprises a metering section; and a diffusing section, with the diffusing section including a shelf, a first outer lobe and a second outer lobe.
