Abstract

A turbo-machine vane having a plurality of internal cavities for the flow of a cooling fluid, and a plurality of openings through the outer wall of the vane for communicating the internal cavities with the outside of the vane. Two rows of openings are provided in the leading edge of the vane, one row on each side of the central line of the leading edge end extending parallel with the central line, and each opening of each row is oriented to direct cooling fluid which flows through it from the interior of the vane away from the central line relative to the rows.
