Abstract

Une couronne aubagée pour stator de turbomachine comprend une virole externe (42), une aube (46) ayant une tête d'aube (52), et deux plateformes (60) agencées circonférentiellement de part et d'autre de la tête d'aube, et fixées sur une face radialement interne (61) de la virole externe au moyen d'organes de fixation démontables. La tête d'aube présente des premières portées coniques (70) en appui sur des deuxièmes portées coniques (72) respectives des deux plateformes de manière à empêcher un déplacement de l'aube radialement vers l'intérieur et selon la direction circonférentielle. La couronne aubagée comporte un pion frangible (73) comprenant une embase (73A) montée sur la virole externe et une tête (73B) faisant saillie radialement vers l'intérieur par rapport à la virole externe et présentant une surface de tête (73C) formant, vis-à-vis d'une surface de sommet (74) de la tête d'aube, une butée s'opposant à un déplacement de l'aube radialement vers l'extérieur.
