    Abstract: A rotor blade (14) for a rotor assembly (10) is provided that includes a root (180, an airfoil (20), and a damper (24). The airfoil (20) includes a base (28), a tip (30), a pressure side wall (36), a suction side wall (38), and a cavity (40) disposed therebetween. The cavity (40) extends substantially between the base (28) and the tip (30), and includes a first cavity portion (44), a second cavity portion (46), and a channel (42) disposed between the first cavity portion (44) and the second cavity portion (46). A plurality of first pedestals (48) are disposed within the first cavity portion (44) adjacent the channel (42), and a plurality of second pedestals (48) are disposed within the second cavity portion (46) adjacent the channel (42). The damper (24) is selectively received within the channel (42).

    Abstract: A gas turbine engine component includes a structure having a cooling passage providing upstream and downstream portions separated from one another by an inner wall and fluidly connected by a bend. First and second trip strips are respectively arranged in the upstream and downstream portions. The first trip strips are arranged at a first spacing from one another. The second trip strips are arranged at a second spacing from one another. A turbulence promoter is arranged in the bend and at a third spacing from the first trip strips that is different than the first spacing. The turbulence promoter is arranged at a fourth spacing from the second trip strips that is different than the second spacing.

    Abstract: An airfoil includes a leading edge, a trailing edge region, a suction surface, a pressure surface, a cooling passageway, and a column of flow separators. The suction surface and the pressure surface both extend axially between the leading edge and the trailing edge region, as well as radially from a root section of the airfoil to a tip section of the airfoil to define a central cavity of the airfoil. The cooling passageway is located within the central cavity at the trailing edge region. The column of flow separators is located in the cooling passageway adjacent the trailing edge and includes a first flow separator having a first longitudinal axis and a second flow separator having a second longitudinal axis. The first longitudinal axis is offset at an angle with respect to the first longitudinal axis.
