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: A hot gas path component for an engine may generally include a substrate extending between an outer surface and an inner surface opposite the outer surface. The outer surface may be configured to be exposed to a hot gas path of the engine. In addition, the substrate may be formed from a non-metallic composite material. The hot gas path component may also include a thermal coating disposed on the inner surface of the substrate. The thermal coating may be applied to the inner surface so as to have a non-uniform distribution along at least a portion of the inner surface, wherein the non-uniform distribution provides for change in a thermal gradient experienced across the hot gas path component between the outer and inner surfaces of the substrate.

Abstract: An engine component with particulate mitigation features is provided. The engine component comprises an internal engine component surface having a cooling flow path on one side thereof and a second component adjacent to the first component. The second component, for example an insert, may have a plurality of openings forming an array wherein the openings extend through the second component at a non-orthogonal angle to the surface of the second component.
