The blade (10a) has a center section (C) geometrically divided into four adjacent concave zones and four adjacent convex zones arranged on both sides of a skeleton line (S) of the blade. The central section has a concave cooling circuit with a set of radial cavities (24a, 26a, 28a) occupying three adjacent concave zones and a convex cooling circuit with another set of radial cavities (30a, 32a, 34a) occupying the convex zones and the remaining concave zones. |
