The blade (1), made with inner (3) and outer (4) bases, has a hollow aerodynamic cavity (2) extending radially between them, and leading and trailing edges. The blade has an interior cooler formed by a perforated liner which is designed to receive a coolant flow and direct it towards the blade's inner walls. The liner is divided by a sealed partition (14) into two cavities (15,16). An inner blade cavity (15) is situated adjacent to the blade's concave wall, and an outer cavity (16) adjacent to its convex wall. The inner cavity is closed at the outer end of the blade by a wall (19), forming two separate cooling circuits (F1,F2,F3,F4). |
