Abstract: A core for forming a cooling microcircuit has at least one row of metering/tripping features configured to form at least one row of protrusions in the cooling microcircuit, a plurality of teardrop features configured to form forming a plurality of fluid passageways in the cooling microcircuit, and a terminal edge. The plurality of teardrop features includes a central teardrop feature having a trailing edge which is spaced from the terminal edge and a first teardrop feature located on a first side of and spaced from the central teardrop feature. The first teardrop feature has a longitudinal axis and is non-symmetrical about the longitudinal axis. A process of using the core and a turbine engine component formed thereby are described.

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.
