Abstract

Pour limiter le débit d'air nécessaire au refroidissement de sa pale, une aube (30) pour turbine de turbomachine d'aéronef comprend, dans sa pale (34), une cavité principale (50) configurée pour collecter un flux d'air principal (F1) depuis une entrée d'air et le faire circuler dans la pale, et une cavité latérale (54) interposée entre la cavité principale (50) et la paroi d'intrados (40) en étant séparée de la cavité principale, la cavité latérale étant configurée pour collecter un flux d'air latéral (F2) depuis l'entrée d'air et le faire circuler dans la pale, la cavité principale comportant au moins trois parties (50A, 50B, 50C) reliées les unes aux autres bout-à-bout de manière à former un serpentin, la cavité latérale (54) étant interposée entre chacune des parties et la paroi d'intrados.
