Title (EN) TURBINE FRAME AND BEARING ARRANGEMENT FOR THREE SPOOL ENGINE
(FR) CADRE DE TURBINE ET AGENCEMENT DE PALIER POUR MOTEUR À TROIS BOBINES
Abstract:
(EN) The present disclosure is directed to a gas turbine engine defining a radial direction, a circumferential direction, an axial centerline along a longitudinal direction. The gas turbine engine defines an upstream end and a downstream end along the longitudinal direction and includes a turbine frame defined around the axial centerline. The turbine frame includes a first bearing surface, a second bearing surface, and a third bearing surface. The first bearing surface corresponds to a first turbine rotor, the second bearing surface corresponds to a second turbine rotor, and the third bearing surface corresponds to a third turbine rotor, and each turbine rotor is independently rotatable.
(FR) La présente invention concerne un moteur à turbine à gaz définissant une direction radiale, une direction circonférentielle, une ligne centrale axiale le long d'une direction longitudinale. Le moteur à turbine à gaz définit une extrémité amont et une extrémité aval le long de la direction longitudinale et comprend un cadre de turbine défini autour de la ligne centrale axiale. Le cadre de turbine comprend une première surface d'appui, une deuxième surface d'appui, et une troisième surface d'appui. La première surface d'appui correspond à un premier rotor de turbine, la deuxième surface d'appui correspond à un deuxième rotor de turbine, et la troisième surface d'appui correspond à un troisième rotor de turbine, et chaque rotor de turbine tourne de manière indépendante.
