Abstract

L’invention concerne une rangée annulaire sectorisée d’aubes fixes pour un distributeur destiné à être monté dans une turbine basse pression d’une turbomachine, la rangée annulaire sectorisée d’aubes fixes comprenant des secteurs (1) d’aubes arrangées circonférentiellement bout à bout, chaque secteur (1) comprenant au moins une plate-forme radialement interne (2) qui porte une ou plusieurs pales (4) s’étendant radialement vers l’extérieur, au moins un support d’abradable (5) relié à la plate-forme interne (2) par une paroi de liaison (7) s’étendant radialement entre ladite plate-forme interne (2) et ledit support d’abradable (5), caractérisée en ce qu’elle comporte au moins un organe d’étanchéité (10) intercalé entre un premier et un second secteurs (1) d’aubes adjacents, ledit organe d’étanchéité (10) comportant une première zone en creux (11) et une seconde zone en creux, l’extrémité circonférentielle correspondante du premier secteur (1) étant engagée dans la première zone en creux (11), l’extrémité circonférentielle correspondante du second secteur (1) étant engagée dans la seconde zone en creux, ledit organe d’étanchéité (10) recouvrant et entourant, au moins partiellement, l’extrémité circonférentielle correspondante de la plate-forme radialement interne (2) et de la paroi de liaison (7) de chacun des premier et second secteurs (1) de distributeur. Figure à publier avec l’abrégé : figure n°3The invention relates to a sectorized annular row of stationary vanes for a distributor intended to be mounted in a low pressure turbine of a turbomachine, the sectorized annular row of stationary vanes comprising sectors (1) of vanes arranged circumferentially end to end, each sector (1) comprising at least one radially internal platform (2) which carries one or more blades (4) extending radially outwards, at least one abradable support (5) connected to the internal platform (2) by a connecting wall (7) extending radially between said internal platform (2) and said abradable support (5), characterized in that it comprises at least one sealing (10) interposed between a first and a second sectors (1) of adjacent blades, said sealing member (10) comprising a first recessed zone (11) and a second recessed zone, the corresponding circumferential end of the first sector (1) being engaged in the first recessed zone (11), the corresponding circumferential end of the second sector (1) being engaged in the second recessed zone, said sealing member (10) covering and surrounding, at least partially, the corresponding circumferential end of the platform radially internal (2) and of the connecting wall (7) of each of the first and second sectors (1) of the distributor.
