Abstract

La présente invention concerne une turbine d'un moteur à turbine à gaz comportant une section à profil aérodynamique comportant des moyens assurant un refroidissement interne avec de l'air, est caractérisée en ce qu'elle comprend un passage fermé 36, 38 formé longitudinalement dans la section à profil aérodynamique, le passage fermé 36, 38 comportant une pluralité d'ouvertures 54, 56 dans la portion commune pour délivrer de l'air au voisinage immédiat de la surface sous pression 44 ou de la surface en dépression 46, afin de former un film d'air de refroidissement adjacent à la surface sous pression 44 ou à la surface en dépression 46, et au moins un orifice fixe 50, 52 dans le passage fermé 36, 38 pour admettre de l'air de refroidissement dans ce passage.
