PROBLEM TO BE SOLVED: To provide a film-cooled engine component in a gas turbine engine.SOLUTION: An engine component 80 for a gas turbine engine generating a hot combustion gas flow comprises: a substrate 82 having a hot surface 84 facing the hot combustion gas flow and a cooling surface 86 facing a cooling fluid flow; and a film hole 90 extending through the substrate 82 and having an inlet 92 provided on the cooling surface 86, an outlet 94 provided on the hot surface 84, and a passage 96 connecting the inlet 92 and the outlet 94. The passage 96 comprises an inlet portion 98 defining an inlet portion centerline 102 and an outlet portion 100 defining an outlet portion centerline 104. The outlet portion centerline 104 forms a first angle to the inlet portion centerline 102, so as to be non-collinear with the inlet portion centerline 102 when viewed from the hot surface 84.SELECTED DRAWING: Figure 5 |
