    Abstract: An airfoil for a gas turbine engine includes pressure and suction walls spaced apart from one another and joined at leading and trailing edges to provide an airfoil having an exterior surface that extends in a radial direction to a tip. A camber line at the tip extends from the leading edge to the trailing edge. Pressure and suction side shelves are arranged in the exterior surface on opposing sides of the camber line respectively in the pressure and suction side walls. A plateau is proud of and separates the pressure and suction side shelves. The plateau is arranged along the camber line and extends to the leading edge.

    Abstract: A casting core (196) for an airfoil (165) includes a first portion (197) extending in a first direction and corresponding to a first cavity (179, 180) of an airfoil (165). The first portion (197) defines a reference plane along a parting line (204) formed by a casting die (202). The first portion (197) defines a plurality of grooves (212) corresponding to a plurality of trip strips (195) of the airfoil (165). Each of the plurality of grooves (212) defines a respective groove axis (214), and the plurality of grooves (212) are distributed in the first direction along a first side of the reference plane such that one or more of the groove axes (214) are oriented with respect to a pull direction (P) of the casting die (202). A method for fabricating a gas turbine engine component is also disclosed.

    Abstract: A component (64) for a gas turbine engine includes an exterior surface that provides pressure and suction sides (86,88). A cooling passage (90) in the component (64) includes a serpentine passageway (94) that has first and second passes (118,120) respectively configured to provide fluid flow in opposite directions from one another. The first pass (118) includes first and second portions (112,114) nested relative to one another and overlapping in a thickness direction. The first and second portions (112,114) are adjacent to one another by sharing a common wall (110). The first portion (112) is provided on the suction side (88). The second portion (114)is provided on the pressure side (86).
