Abstract

L'invention concerne un ensemble de pièces de turbomachine (50) d'axe longitudinal (X), comprenant au moins une première et une deuxième aubes de stator (1, 1') adjacentes, chaque première et deuxième aubes de stator (1, 1') étant métalliques et comprenant une pale (2) et une plateforme (9) intégrée s'étendant de part et d'autre de la pale en formant une partie de plateforme intrados (9I) et une partie de plateforme extrados (9E), l'ensemble comprenant au moins une ailette (13) allongée suivant une direction sensiblement parallèle à l'axe longitudinal (X), présentant un corps avec une section transversale de forme triangulaire s'étendant radialement vers l'extérieur par rapport à l'axe longitudinal (X) et s'étendant axialement à chevauchement supérieur de bords longitudinaux (11 A, 11 B) adjacents de chacune des parties de plateforme intrados et extrados des aubes adjacentes, ce chevauchement étant au moins longitudinalement partiel sur lesdits bords longitudinaux des parties de plateforme.
