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 substrate 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 engine component also includes a flow conditioning structure provided upstream of the outlet on the hot surface. The flow conditioning structure can include a ridge extending from the hot surface.

Abstract: An apparatus and method relating to a film-hole of a component of a turbine engine. The film-hole can extend from an inlet to an outlet to define a passage. The film-hole can include a laid back section where a coating can be applied. The method can include forming the film-hole in the component and applying the coating to the component to maintain a specific geometry.

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.
