The invention refers to a component defining a blade or a vane for a rotary machine having a rotor rotatable about an axis. The component includes an inner space forming a passage for a cooling fluid between first and second walls. First ribs project from the fist wall and extend essentially in parallel to each other to form fist channels for the fluid from a leading part of the inner space to a trailing part of the space. The first ribs extend in a first direction forming a first angle of inclination to the axis in the leading part and in a second direction forming a second angle of inclination to the axis in the trailing part. The first angle is greater than the second angle. |
