Title (EN) TURBINE ASSEMBLY WITH RING SEGMENTS
(FR) ENSEMBLE DE TURBINE À SECTEURS D'ANNEAU
Abstract:
(EN) The invention relates to a turbine assembly (1) comprising an annular structure extending circumferentially about an axial direction (DA) and comprising ring segments (10) arranged circumferentially end to end and comprising adjacent connection faces (13a), coupled by sealing tongues (21, 22), in the wall (11) and in the flange (12). The invention is characterised in that the grooves (31, 32) and tongues (21, 22) are curved, the tongues (21, 22) having a bending degree of freedom in respect of their mounting positions when air pressure is exerted from upstream to downstream between the adjacent connection faces (13a) during operation of the turbine, tongue (22) having a contact point (220) with a point (213) on tongue (21).
(FR) L'invention concerne un ensemble(1) de turbine, comprenant une structure annulaire s'étendant circonférentiellement autour d'une direction axiale (DA)et comportant des secteurs (10) d'anneau disposés circonférentiellement bout à bout et comportant des faces (13a) de raccordement adjacentes, reliées par des languettes (21, 22) d'étanchéité, dans la paroi (11) et dans le rebord (12). L'invention est caractérisée en ce que les rainures (31, 32) et les languettes (21, 22) sont courbes, les languettes (21, 22) ayant un degré de liberté en flexion partant de leur position de montage en présence d'une pression d'air exercée de l'amont vers l'aval entre les faces (13a) de raccordement adjacentes lors du fonctionnement de la turbine, la languette (22) ayant un point (220) de contact avec un point (213) de la languette (21).
