Abstract

The present disclosure is directed to a turbomachine airfoil including an exterior wall having a trailing edge. The exterior wall defines a radially-extending cooling cavity and one or more trailing edge cooling passages extending through the exterior wall. Each trailing edge cooling passage includes an inlet in fluid communication with the cooling cavity and a first portion in fluid communication with the inlet. Each trailing edge cooling passage also includes a second portion in fluid communication with the first portion. The second portion includes a first outlet defined by the exterior wall at the trailing edge. Each trailing edge cooling passage further includes a third portion in fluid communication with the first portion. The third portion includes a second outlet defined by the exterior wall at the trailing edge. The second and third portions are separated by a rib extending upstream from the trailing edge.
