A system for connecting a low-pressure jet (12) to a transition duct (149 in a gas turbine, in which the said low-pressure jets (12) are arranged in sectors of two or three stator blades and are filled on to the ring of the jets. The platforms (11) of the jets (12) are provided with a channel (13) inside which the transition duct (14) is positioned by means of an edge (15). Furthermore, centring between the transition duct (14) and the ring of the jets (12) is achieved directly using centring means at three or more points on the rings of the jets (12).
Cette invention se rapporte à un système servant à raccorder une tuyère basse pression (12) à un conduit de transition (14) dans une turbine à gaz, dans laquelle les tuyères basses pression (12) sont disposées en secteurs de deux ou trois ailettes de stator et sont montées sur l'anneau des tuyères. Des plates-formes (11) des tuyères sont pourvues d'un canal (13), à l'intérieur duquel le conduit de transition (14) vient se positionner à l'aide d'un rebord (15). En outre, le centrage entre le conduit de transition (14) et l'anneau des tuyères (12) est obtenu directement grâce à un moyen de centrage en trois points au moins sur les anneaux des tuyères (12).
