CA 2663063

A gas turbine engine has a compressor assembly (22) and a turbine assembly (24) rotationally mounted on a shaft (25), the turbine assembly (24) being driven by hot gases discharged from a combustion chamber (28) disposed between the compressor and turbine assemblies (22, 24), the compressor (22) having a centrifugal impeller (50) for pressurizing and impelling air into the combustion chamber (28). The engine also includes an impeller shroud (40) covering the bladed portion of the centrifugal impeller (50), the impeller shroud (40) having a support bracket (60) having a thin and curved load-isolating profile for supporting a strut (72) that secures the impeller shroud (40) to a case (70) of the engine.

L'invention concerne une turbine à gaz comprenant un ensemble compresseur (22) et un ensemble turbine (24) montés rotatifs sur un arbre (25), l'ensemble turbine (24) étant entraîné par des gaz chauds évacués à partir d'une chambre de combustion (28) disposée entre lesdits ensembles compresseur et turbine (22, 24), le compresseur (22) possédant une roue centrifuge (50) permettant de mettre sous pression et de propulser l'air dans la chambre de combustion (28). Le moteur comprend également un flasque de roue (40) recouvrant la partie à ailettes de la roue centrifuge (50), ce flasque de roue (40) comportant un support isolant (60) présentant un profil fin et incurvé pour le support d'une tige (72) assurant la fixation du flasque de roue (40) sur un carter (70) du moteur.
