    Abstract: A process for providing cooling fluid holes in an airfoil portion of a turbine engine component comprising: positioning a first core with metering/tripping features that form a row of protrusions, and teardrop features that form a fluid passageways, the teardrop features including a central teardrop feature having a trailing edge, a first teardrop feature located on a first side of and spaced from the central teardrop feature, the first teardrop feature having a longitudinal axis and being non-symmetrical about the longitudinal axis, and a second teardrop feature located on a second side of and spaced from the central teardrop feature, the second teardrop feature having a longitudinal axis and non-symmetrical about the longitudinal axis; joining the core to a ceramic core; forming the turbine engine component; removing the core, forming a cooling microcircuit with fluid outlets; and drilling a central portion of the cooling microcircuit forming a converging/diverging outlet.

    Abstract: An assembly for a turbine engine includes a plurality of vane segments. The vane segments are fastened together and form an adjustable stator vane that pivots about a variable vane axis. The adjustable stator vane includes a stator vane body, a shaft and a flange. The stator vane body extends axially between a first end and a second end, and includes an airfoil, a body surface and a cavity. The body surface is located at the first end. The cavity extends axially from an inlet in the body surface and into the airfoil. The shaft extends along the variable vane axis from the first end. The flange extends circumferentially at least partially around the inlet, and radially from the stator vane body. A first of the vane segments includes the flange. A second of the vane segments includes at least a portion of the airfoil.

    Abstract: A blade for a gas turbine engine includes an airfoil having a tip with a terminal end surface and multiple squealer pockets recessed into the terminal end surface. A method of cooling a blade includes the steps of providing cooling fluid to a first squealer pocket in an airfoil tip, and providing cooling fluid to a second squealer pocket in the airfoil tip in an amount that is different than that provided to the first squealer pocket.

    Abstract: An airfoil includes a supply passage to provide a coolant, an airfoil section that has walls that define an internal cavity, a baffle seated in the internal cavity, and a seal proximate the edge of the baffle. The baffle is seated such that there is a gap between the baffle and at least one of the walls. The baffle includes a baffle wall that has cooling holes and that defines an interior baffle region. The seal seals off the gap such that the coolant that exits the supply passage will be directed to flow into the interior baffle region.
