Abstract

L'aube de moteur à turbine à gaz refroidie comprend une pièce de fonderie (11) et une chemise longitudinale (14) obtenue par formage de tôle; la pièce de fonderie (11) comporte un corps longitudinal pourvu d'une cavité longitudinale (16) avec une première ouverture (19) et une seconde ouverture (20) aux extrémités, la chemise (14) étant montée dans la cavité (16) en étant fixée de façon solidaire à la paroi de la première ouverture (19), et dont une portion d'extrémité (21) est libre de coulisser dans la seconde ouverture formant glissière (20). Ladite portion d'extrémité (21) comprend une portion (22) aux dimensions transversales rétrécies par rapport aux dimensions transversales de la glissière (20).
