Title (EN) DOUBLE-BODY GAS TURBINE ENGINE PROVIDED WITH AN INTER-SHAFT BEARING
(FR) MOTEUR A TURBINE A GAZ A DOUBLE CORPS POURVU D ' UN PALIER INTER-ARBRES
Abstract: front page image
(EN)The present invention relates to a double-body gas turbine engine (1), including a low-pressure body LP (9C) and a high-pressure body HP (10C), rotatably mounted about a single shaft in a stationary casing (2), the low-pressure body LP (9C) having a compressor and a turbine connected by a low-pressure shaft LP (9), said low-pressure shaft LP being supported by an upstream LP bearing (P2), a first downstream LP bearing (P5') and an additional downstream LP bearing (P6) by the stationary casing, the high-pressure body HP (10C) being supported by an upstream HP bearing (P3) and a downstream HP bearing (P4) which is an inter-shaft bearing including an inner track rigidly connected to the HP turbine rotor (10C) and an outer track rigidly connected to the LP shaft (9).
(FR)La présente invention porte sur une moteur à turbine à gaz (1) à double corps, comprenant un corps basse pression BP (9C) et un corps haute pression HP (10C), montés rotatifs autour d'un même axe dans un carter fixe (2), le corps basse pression BP (9C) présentant un compresseur et une turbine reliés par un arbre basse pression BP (9) ledit arbre basse pression BP étant supporté par un palier BP amont (P2), un premier palier BP aval (P5') et un palier BP aval supplémentaire (P6) par le carter fixe, le corps haute pression HP (10C) étant supporté par un palier HP amont (P3) et un palier HP aval (P4) qui est un palier inter-arbres comprenant une piste intérieure solidaire du rotor de turbine HP (10C) et une piste extérieure solidaire de l'arbre BP (9).
