Abstract: A turbine component includes a first structure exposed to a hot gas path and a second structure integral with the first structure but isolated from the hot gas path. A first fluid passage in the first structure delivers a thermal transfer fluid, e.g., air, through the first structure to cool the first structure. A second fluid passage is defined within the second structure and is in fluid communication with the first fluid passage. After heat transfer in the first structure, the thermal transfer fluid is hotter than a temperature of the second structure and thus increases the temperature of the second structure. The heat transfer to the second structure reduces a temperature difference between the first structure and the second structure that would, without heating, cause thermal stress between the structures. The heating of the second structure reduces the need for early maintenance and lengthens the lifespan of the component.

Abstract: A turbomachine component has a wall outer surface and an internal coolant source. A film-cooling hole is in the wall and extends from the internal coolant source to the wall outer surface. The film-cooling hole includes a metering section in fluid communication with the internal coolant source, and a diffuser section in fluid communication with the metering section and including a first internal surface spaced from a second internal surface. A coating collector receives part of a coating and is part of the diffuser section. The film-cooling hole also includes a hood section including a member extending outwardly from the wall outer surface. The member may include a hood internal surface contiguous with the first internal surface of the diffuser section and a hood outer surface parallel to the wall outer surface. The hood section reduces, and possibly prevents, the coating from filling the film-cooling hole during application thereof.
