A COMPONENT FOR A GAS TURBINE

摘要

The invention refers to a component (1) defining a blade or a vane for a rotary machine having a rotor (3) rotatable about an axis (x). The component comprises an inner space (6) forming a passage for a cooling fluid between first and second walls (7, 8). First ribs (13', 13'') project form said first wall and extend essentially in parallel to each other to form first channels for said fluid from a leading part (9) of the inner space to a trailing part (10) thereof. Said first ribs (13', 13'') extend in a first direction forming a first angle (a) of inclination to said axis (x) in said leading part (9) and in a second direction forming a second angle (b) of inclination to said axis in said trailing part (10). The first angle (a) is greater than the second angle (b).
