Title (EN) SEAL INTERFACE BETWEEN A TRANSITION DUCT AND A STAGE ONE VANE STRUCTURE
(FR) INTERFACE D'ÉTANCHÉITÉ ENTRE UN CONDUIT DE TRANSITION ET UNE STRUCTURE D'AUBE À ÉTAGE UNIQUE
Abstract:
(EN) A gas turbine sealing interface (10) to seal (30) a gap between a transition duct (12) and a turbine section component is provided. The transition duct (12) includes an outlet exit frame (12, 14) including at least one fastener hole (18). The turbine section component includes a first stage vane structure including an upstream lip (22). A seal (30) couples the outlet exit frame (12, 14) to the first stage turbine vane structure (16). An L-shaped rail including a flat portion (31) and a lipped portion (29) disposed perpendicularly to the flat portion (31). The seal (30) is secured to the outlet exit frame (12, 14) via the L-shaped rail. An upstream portion of the seal (30) includes a U-shaped cross section forming a first groove (26). A downstream portion of the seal (30) comprises a groove (26) which engages the upstream lip (22) of the first stage turbine vane structure (16). A gas turbine engine including a radially inner sealing interface (20) and a radially outer sealing interface (10, 20) is also provided.
(FR) L'invention concerne une interface d'étanchéité de turbine à gaz (10) pour sceller (30) un espace entre un conduit de transition (12) et un composant de section de turbine est prévue. Le conduit de transition (12) comprend un cadre d'issue de sortie (12, 14) comprenant au moins un trou de fixation (18). Le composant de section de turbine comprend une structure d'aube de premier étage comprenant une lèvre amont (22). Un joint d'étanchéité (30) couple le cadre d'issue de sortie (12, 14) à la structure d'aube de turbine de premier étage (16). Un rail en forme de L comprend une partie plate (31) et une partie à lèvre (29) disposée perpendiculairement à la partie plate (31). Le joint d'étanchéité (30) est fixé à la structure d'issue de sortie (12, 14) par l'intermédiaire du rail en forme de L. Une partie amont du joint d'étanchéité (30) comprend une section transversale en forme de U formant une première rainure (26). Une partie aval du joint d'étanchéité (30) comprend une rainure (26) qui vient en prise avec la lèvre amont (22) de la structure d'aube de turbine de premier étage (16). L'invention concerne également un moteur à turbine à gaz comprenant une interface d'étanchéité radialement interne (20) et une interface d'étanchéité radialement externe (10, 20).
