Abstract
An engine component for a gas turbine engine includes a film-cooled substrate having a hot surface facing hot combustion gas flow and a cooling surface facing a cooling fluid flow. A film hole extends through the substrate to an outlet on the hot surface. A flow conditioning structure is provided upstream of the outlet.

An engine component for a gas turbine engine, the gas turbine engine generating hot combustion gas flow, comprising:
- a substrate having a hot surface facing the hot combustion gas flow and a cooling surface facing a cooling fluid flow, the hot combustion gas flow generally defining an upstream direction and a downstream direction relative to the hot surface;
- 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;
- and
- a flow conditioning structure provided upstream of the outlet on the hot surface, wherein the flow conditioning structure is configured to divert at least a portion of the hot combustion gas flow around the cooling fluid flow emerging from the outlet.
