    Abstract: An airfoil includes an airfoil section that has an internal cavity and first and second endwall sections between which the airfoil section is disposed. The first endwall section includes a guide portion that has a guide opening flanked by first and second bearing lands. The first bearing land is between the guide opening and a first port in the first endwall section that opens to the internal cavity of the airfoil section. The second bearing land is between the guide opening and a second port in the first endwall section that also opens to the internal cavity. A tie member extends through the internal cavity and secures the first and second endwall sections together to trap the airfoil section. The tie member extends through the guide opening in the first endwall section. A spring member on the first and second bearing lands tensions the tie member.

    Abstract: A vane platform cooling system may comprise a combustor shell and a combustor panel. A cavity may be located between the combustor shell and the combustor panel. A surface of the cavity may be angled toward the combustor shell. An orifice may be formed in a vane platform located aft of the combustor panel. A standoff located in the cavity may direct air toward the vane platform. An aperture may be formed in a surface of the vane platform. A channel formed through the vane platform may connect the orifice and aperture.

    Abstract: Airfoil bodies having a first core cavity within the airfoil body and a second core cavity located within the airfoil body and adjacent the first core cavity, wherein the second core cavity is defined by a first cavity wall, a second cavity wall, a first exterior wall, and a second exterior wall, wherein the first cavity wall is located between the second core cavity. The first cavity wall includes a first surface angled toward the first exterior wall and a second surface angled toward the second exterior wall and at least one first cavity impingement hole is formed within the first surface. A funneling feature extends the second core cavity along the first exterior wall to funnel the first impingement flow along the first exterior wall.

    Abstract: Airfoil bodies having a first core cavity and a second core cavity located within the airfoil body and adjacent the first core cavity, wherein the second core cavity is defined by a first cavity wall, a second cavity wall, a first exterior wall, and a second exterior wall, wherein the first cavity wall is located between the second core cavity and the first core cavity. The first cavity wall includes a first surface angled toward the first exterior wall and a second surface angled toward the second exterior wall. At least one first cavity impingement hole is formed within the first surface and has an oblong shape with a long axis oriented between 0° and 180° relative to the first exterior side wall.
