CA 2550890

A gas turbine engine (10) having an oil cavity architecture and bearing placement which reduce heat rejection and oil system complexity by enclosing the reduction gearbox bearings (54) and at least the shaft bearings (42, 44) supporting the high pressure shaft (38) in the same oil cavity (60).

L'invention concerne un moteur à turbine à gaz amélioré (10) qui comprend une cavité à huile simple (60) renfermant le palier de réducteur de vitesse (54) et au moins le palier d'arbre (42, 44); la mise en place de palier conçue pour réduire le rejet de chaleur; et des arbres interne (36) et externe (38) concentriques, l'arbre externe (38) étant en porte-à-faux. De plus, l'architecture de la cavité à huile simple permet de supprimer les tuyaux extérieurs et le matériel associé, ainsi que la nécessité d'un système de récupération d'huile d'une boîte d'entraînement des accessoires (AGB).
