Abstract: An apparatus and method of forming an engine component having an outer wall forming an interior. The interior can be separated into two or more flow paths or flow channels. The two flow paths can be formed by casting having one or more core ties connecting the flow paths during casting. One or more core tie holes can be formed remnant of the core ties during casting in order to fluidly couple the two or more flow paths or flow channels.

Abstract: An apparatus and method for minimizing a cross-flow across an engine cooling hole can include a component, such as an airfoil, having an outer wall bounding an interior from an exterior. A cooling passage is formed in the interior of the component for cooling the engine component. A cooling hole or film hole can be provided in the outer wall fluidly coupling the interior to the exterior. The cooling passage can be shaped to minimize cross-flow over the cooling hole at the interior of the component.

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 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.
