Abstract

Turbine à gaz comportant des chambres de combustion disposées en barillet autour du corps du compresseur et des pièces de transition véhiculant les gaz des chambres vers la directrice d'entrée de la turbine. Une jupe interne et une jupe externe s'emboîtant à une extrémité sur des ceintures entourant les pièces de transition et s'emboîtant à l'autre extrémité dans les rainures ménagées dans la directrice d'entrée assurent la liaison et l'étanchéité entre sorties des pièces de transition et directrice d'entrée. Diminution des contraintes dues au gradient thermique dans les pièces de transition des turbines à gaz.
