Abstract
A turbine blade for a turbomachine, including a vane extending in a spanwise direction between a root and a tip, a first inner side cavity running along a pressure-side wall and a second inner side cavity running along a suction-side wall. The blade further includes at least one inner central duct configured to collect air intended to cool the vane. The central duct extends between the side cavities, being separated from the side cavities to be at least partially thermally isolated from the pressure-side wall and the suction-side wall. The side cavities communicate with each other in a junction region located downstream from the central duct, over a majority of a height of the central duct in the spanwise direction.
