| 摘要 |
The invention concerns a turbine blade (91) comprising a root (P), a vane extending in a spanwise direction (EV), ending at a tip (S) and comprising a leading edge and a trailing edge and a pressure-side wall and a suction-side wall, said vane further comprising: at least one upstream duct (93) configured to collect air at the root (P) to cool the leading edge, discharging said air through holes passing through the wall of the leading edge; at least one downstream duct (96) separate from the upstream duct (93) and configured to collect air at the root (P) to cool the trailing edge, discharging said air through holes (97) passing through the pressure wall upstream from the trailing edge; an inner side cavity (101) running along the pressure-side wall to form a heat shield insulating the downstream duct (96). |
