Patent ID: 10519781

Abstract:
Airfoils having hollow bodies defining first and second airfoil cavities and having inner and outer diameter ends, a first airfoil platform at one end of the hollow body having a gaspath surface and a non-gaspath surface, wherein the hollow body extends from the gaspath surface. A first cavity opening is formed in the non-gaspath surface of the platform to fluidly connect to the first airfoil cavity and a second cavity opening in the platform is fluidly connected to the second airfoil cavity. A first turn cap is fixedly attached to the first airfoil platform on the non-gaspath surface covering the first and second cavity openings of the first airfoil platform and defines a first turning cavity such that the first cavity opening in the first airfoil platform is fluidly connected to the second cavity opening in the first airfoil platform by the first turning cavity.
