Abstract

TITRE  : ENSEMBLE DE TURBOMACHINE MUNI D’UN STATOR ET D’UN ROTOR Un aspect de l’invention concerne un ensemble (10) de turbomachine comprenant un stator (100) et un rotor (50) d’axe X. Le stator comprend des aubes fixes (20) réparties annulairement autour de l’axe X, chacune des aubes fixes étant équipée d’une plateforme interne (210) comprenant un rail de guidage (212) ; et des patins sectorisés (30) répartis annulairement autour de l’axe X, chacun agencé entre au moins une aube fixe et le rotor et comprenant une portion engagée (310) logée à l’intérieur du rail de guidage (212). Figure à publier avec l’abrégé : Figure 10
