Patent attributes
A turbine hot gas path (HGP) component includes a body having an exterior surface exposed to a hot gas path, and a cooling circuit defined along an interior surface of the body and fluidly coupled to a coolant source. The cooling circuit includes a plurality of sections spaced from one another but fluidly connected. Each section includes a wall defining at least one cooling passage, and a connector wall coupling between the wall of a first section of the plurality of sections and the wall of an adjacent, second section of the plurality of sections. The wall of the first section and the wall of the adjacent, second section are spaced apart, segregating stress between the sections. The connector wall is more flexible than: the wall of the first section, the wall of the adjacent, second section, and the body, allowing stress relief between the sections.
