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 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.
Claims10
A core for forming a cooling microcircuit comprising:
- at least one row of metering/tripping features configured to form at least one row of protrusions in said cooling microcircuit;
- a plurality of teardrop features configured to form a plurality of fluid passageways in said cooling microcircuit;
- a terminal edge;
- said plurality of teardrop features including a central teardrop feature having a trailing edge which is spaced from said terminal edge, said central teardrop feature being smaller in size than other teardrop features;
- and
- said plurality of teardrop features including a first teardrop feature located on a first side of and spaced from said central teardrop feature, said first teardrop feature having a longitudinal axis and being asymmetrical about said longitudinal axis, wherein said plurality of teardrop features include a plurality of additional teardrop features and each of said additional teardrop features has a trailing edge which is closer to said terminal edge than said terminal edge of said central teardrop feature.
