Abstract

Distributeur (18) pour turbine à gaz comprenant une pluralité de secteurs d’aubes fixes (20) disposés circonférentiellement bout à bout et comprenant une plateforme (22) dont chaque première partie d’extrémité comporte au moins une première fente (30a) débouchant circonférentiellement et comprenant une surface radialement interne (36) présentant une première portion de surface (42) s’étendant depuis le fond de la fente et jusqu’à une seconde portion de surface (44) s’étendant jusqu’au débouché de la fente, et une surface radialement externe (38) présentant une troisième portion de surface (46) s’étendant depuis le fond de la fente et jusqu’à une quatrième portion de surface (48) s’étendant jusqu’au débouché de la fente. Ladite première portion de surface et ladite troisième portion de surface sont sensiblement parallèles l’une à l’autre, et ladite deuxième portion de surface et ladite quatrième portion de surface s’éloignent l’une de l’autre en allant vers le débouché. Figure de l’abrégé : Figure 9Distributor (18) for a gas turbine comprising a plurality of fixed vane sectors (20) arranged end to end circumferentially and comprising a platform (22) of which each first end part comprises at least one first slot (30a) opening out circumferentially and comprising a radially inner surface (36) having a first surface portion (42) extending from the bottom of the slot and to a second surface portion (44) extending to the outlet of the slot, and a radially outer surface (38) having a third surface portion (46) extending from the bottom of the slot and to a fourth surface portion (48) extending to the outlet of the slot. Said first surface portion and said third surface portion are substantially parallel to each other, and said second surface portion and said fourth surface portion move away from each other towards the outlet.
