Abstract

Aubage de stator (112) pour une turbomachine, cet aubage ayant une forme générale annulaire autour d'un axe et comportant une rangée annulaire d'aubes (114) dont les extrémités radialement externes sont reliées à une virole annulaire externe (116), cette virole externe comportant des moyens (118) d'accrochage sur un carter (120) de turbomachine et étant sectorisée et formée d'une succession de secteurs de virole disposés circonférentiellement autour dudit axe, les secteurs de virole comportant au niveau de leurs extrémités circonférentielles des bords (22) en regard qui comportent des fentes de logement de languettes (124) d'étanchéité inter-secteurs, chaque languette ayant une forme générale allongée et étant engagée d'une part dans une fente d'un bord d'un secteur de virole et d'autre part dans une fente d'un bord en regard d'un secteur de virole adjacent, et les fentes desdits bords débouchant axialement à l'extrémité aval de la virole, caractérisé en ce que chacune desdites languettes comprend à son extrémité aval un rebord (124b) d'appui axial, ce rebord étant orienté radialement vers l'extérieur et étant situé à l'extérieur des fentes de logement de cette languette, en aval de l'extrémité aval de la virole.Stator blade (112) for a turbomachine, this blade having a generally annular shape around an axis and comprising an annular row of blades (114) whose radially outer ends are connected to an outer annular shell (116), this outer shell comprising means (118) for hooking onto a casing (120) of a turbomachine and being sectored and formed of a succession of shell sectors disposed circumferentially around said axis, the shell sectors comprising at their circumferential ends opposite edges (22) which comprise slots for housing inter-sector sealing tabs (124), each tab having a generally elongated shape and being engaged on the one hand in a slot of an edge of a sector of shell and on the other hand in a slot of an edge facing an adjacent shell sector, and the slots of said edges opening axially at the downstream end of the shell, characterized in that each of said tab tes comprises at its downstream end an axial bearing flange (124b), this flange being oriented radially outwards and being located outside the housing slots of this tongue, downstream from the downstream end of the ferrule .
