BLADE OR VANE FOR A TURBOMACHINE

摘要

A component defines a blade or a vane for a rotor rotatable about a rotary axis. An inner space of the component is limited by first and second walls, and forms a passage for a cooling fluid. First and second ribs project form the first and second walls, respectively, and form first and second channels for the fluid from a leading end to a trailing end of the ribs. The first and second ribs intersect and are directly connected to each other at said intersections. The first and second ribs intersect at an intersection joint in the proximity of the trailing end in such a way that the first channel and the second channel form a common outlet channel with a flow area.
