Abstract

Carter inter-turbines pour turbomachine du type turbine vane frame remplissant la fonction de distributeur de turbine dans une telle turbomachine, comprenant une virole interne (9), une virole externe, une pluralité de bras (11) s’étendant entre la virole interne (9) et la virole externe, et au moins un jeu de N aubes séparatrices (12) positionnées circonférentiellement entre deux bras successifs (11), chaque aube séparatrice (12) présentant une corde axiale à mi-hauteur plus courte que la corde axiale à mi-hauteur des bras (11), dans lequel lesdits deux bras successifs (11) définissent une position de référence pour chacune desdites N aubes séparatrices (12), ces positions de référence étant régulièrement espacées circonférentiellement entre les deux bras successifs (11), et dans lequel au moins une aube séparatrice (12-1) dudit jeu de N aubes séparatrices (12) est décalée circonférentiellement par rapport à sa position de référence.
