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). The cooled gas turbine engine blade comprises a casting (11) and a longitudinal liner (14) obtained by forming sheet metal; the casting (11) comprises a longitudinal body provided with a longitudinal cavity (16) with a first opening (19) and a second opening (20) at the ends, the sleeve (14) being mounted in the cavity (16) being secured to the wall of the first opening (19), and having an end portion (21) free to slide in the second slider opening (20). Said end portion (21) comprises a portion (22) with transverse dimensions narrowed relative to the transverse dimensions of the slide (20).
