BLADE FOR A TURBO MACHINE IMPELLER AND METHOD FOR MODELLING THE SAME |
摘要 |
Blade for a turbo machine impeller comprising a root, an air foil and a tip. The root and the tip comprise platforms having surfaces (15) on the side of the air foil, the surfaces respectively being referred to as the root and tip flow path. Each of these flow paths is made up of a pressure-face part and of a suction-face part which are situated respectively on the side of the pressure face and of the suction face and are separated by a crest curve (45, 65). Blade manufacture is made easier notably by virtue of the fact that any point on a first surface out of the pressure face and the suction face and any point on the root and tip flow path parts situated on the side of the first surface has a normal that makes an acute or right angle with respect to a direction referred to as the first direction of manufacture. Method for modelling the blade. |
