Abstract

L’invention concerne une turbomachine comprenant un circuit de refroidissement comprenant une première conduite (19) configurée pour amener un premier fluide (S1) dans l’enceinte (13, 13b) du palier avant (11, 12) et une deuxième conduite (21) configurée pour amener un deuxième fluide (S2) au niveau du compresseur haute pression (3). La première conduite (19) et la deuxième conduite (21) comprennent chacune une entrée (20, 22) distinctes, l’entrée (20) de la première conduite (19) s’étendant en amont de l’entrée (22) de la deuxième conduite (21). Par ailleurs, la turbomachine comprend un dispositif d’ajustement (23) d’un débit du deuxième fluide (S2) dans la deuxième conduite (21), ledit dispositif d’ajustement (23) comprenant un contrôleur (24) configuré pour modifier ledit débit en fonction d’une phase de vol de la turbomachine (7).
