Title (EN) TURBINE RING ASSEMBLY WITH AXIAL RETENTION
(FR) ENSEMBLE D'ANNEAU DE TURBINE AVEC MAINTIEN AXIAL
Abstract:
(EN) The invention relates to a turbine ring assembly including a plurality of ring sectors (10) forming a turbine ring (1), and a ring support structure (3) including an upstream ring-shaped flange (32) and a downstream ring-shaped flange (36), each ring sector (10) including a first horizontal sealing tab (21), an upstream vertical sealing tab (22) and a first downstream vertical sealing tab (23). Each ring sector (10) further includes a second horizontal sealing tab (20) above the first horizontal sealing tab (21) in the radial direction of the ring. A first angled sealing element (24) is housed in both a vertical groove (42) in the upstream lug (14) and a second horizontal groove (40), while a second angled sealing element (25) is housed in both a first horizontal groove (41) and a first vertical groove (43) in the downstream lug (16).
(FR) Un ensemble d'anneau de turbine comprenant une pluralité de secteurs d'anneau (10) formant un anneau de turbine (1) et une structure de support d'anneau (3) comprenant une bride annulaire amont (32) et une bride annulaire aval (36), chaque secteur d'anneau (10) comprenant une première languette d'étanchéité horizontale (21), une languette d'étanchéité verticale amont (22) et une première languette d'étanchéité verticale aval (23). Chaque secteur d'anneau (10) comprend en outre une deuxième languette d'étanchéité horizontale (20) au-dessus de la première languette d'étanchéité horizontale (21) suivant la direction radiale de l'anneau. Un premier élément d'étanchéité coudé (24) est logé à la fois dans une rainure verticale (42) présente dans la patte amont (14) et dans une deuxième rainure horizontale (40) tandis qu'un deuxième élément d'étanchéité coudé (25) est logé à la fois dans une première rainure horizontale (41) et dans une première rainure verticale (43) présente dans la patte aval (16).
