Abstract: An engine component assembly includes a first engine component having a hot surface in thermal communication with a hot combustion gas flow and a cooling surface with at least one cavity. A second engine component is spaced from the cooling surface, and includes at least one cooling aperture. The cooling aperture is arranged such that cooling fluid impinges on the cooling surface at an angle.

Abstract: The present disclosure generally relates to methods and apparatuses for forming cast parts having cast in features aligned with a casting core. The part is cast around a casting core within a casting shell. The casting core has a first feature that creates a corresponding second feature of the cast part. The casting core includes a third alignment feature that creates a corresponding fourth feature of the cast part spaced apart from the second feature of the cast part. A machining tool is aligned with the second feature of the cast part based on the fourth feature of the cast part. The machining tools machines the cast part to create the at least one passageway aligned with the second feature.
