<p>The vane (10) has ribs (50) formed near a trailing edge (42) of a blade (40). Ends of the ribs are more close to the trailing edge and/or section of the ribs is large in zones in which operating temperature of the vane is high. The ribs are parallel to an upper surface (32) of a platform (30) of the vane. The ribs ensure rigidification of a wall (54) of the trailing edge. Notches (60) are formed between the consecutive ribs, and air injection holes are formed in the notches.</p> |
