ENGINE COMPONENT

摘要

An engine component for a gas turbine engine includes a film-cooled substrate having a hot surface facing hot combustion gas and a cooling surface facing a cooling fluid flow. The substrate includes one or more film holes that have a passage with an inlet and an outlet, where the passage includes portions that are angled relative to each other.

1. 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; and 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; wherein the passage comprises an inlet portion defining an inlet portion centerline and an outlet portion defining an outlet portion centerline, which forms a first angle relative to the inlet portion centerline such that the outlet portion centerline is non-collinear with the inlet portion centerline when viewed from the hot surface.
