Abstract

L'invention concerne un turboréacteur (1) comprenant une enveloppe intérieure (2) entourée par une enveloppe intermédiaire (3) délimitant conjointement une veine primaire qui est entourée par une veine secondaire, - ce turboréacteur (1) comprenant dans la veine primaire une turbine basse pression (4) comprenant un distributeur (6) ainsi qu'un premier et un second étage rotatif (7, 9) ; - le distributeur comprenant des aubes fixes (11) traversées par de l'air de refroidissement collecté au niveau d'un compresseur haute pression ; - le premier étage rotatif (7) comprenant un premier disque (14) portant des premières aubes (13) et le second étage rotatif (9) comprenant un second disque (17) portant des secondes aubes (16), ces disques (14, 17) étant portés par un tourillon basse pression (22) ; - les aubes (13) du premier étage rotatif (7) et les aubes (16) du second étage rotatif (9) étant refroidies par de l'air de refroidissement ayant traversé les aubes fixes (11) du distributeur (6).The invention relates to a turbojet engine (1) comprising an inner envelope (2) surrounded by an intermediate envelope (3) jointly delimiting a primary vein which is surrounded by a secondary vein, - this turbojet engine (1) comprising in the primary vein a turbine low pressure (4) comprising a distributor (6) as well as a first and a second rotary stage (7, 9); - the distributor comprising fixed vanes (11) traversed by cooling air collected at the level of a high pressure compressor; the first rotary stage (7) comprising a first disc (14) carrying first vanes (13) and the second rotary stage (9) comprising a second disc (17) carrying second vanes (16), these discs (14, 17) being carried by a low pressure journal (22); - the vanes (13) of the first rotary stage (7) and the vanes (16) of the second rotary stage (9) being cooled by cooling air having passed through the stationary vanes (11) of the distributor (6).
