Abstract
La présente invention concerne un conduit d'alimentation (80) d'un compresseur (90) d'une turbomachine (10), formé d'une paroi interne (82) et d'une paroi externe (81) de révolution autour d'un axe (x) et en regard l'une de l'autre de manière à définir une veine de circulation d'un fluide, ladite veine permettant d'acheminer le fluide depuis l'entrée (83) du conduit vers l'entrée (84) du compresseur (90), le rayon (Rext,cond) de la paroi externe (81) du conduit à l'entrée (83) du conduit étant supérieur au rayon (Rext,comp) du conduit à l'entrée (84) du compresseur, le conduit (80) étant caractérisé en ce qu'il comprend au moins une portion (P) pour laquelle le rayon (Rext) de la paroi externe (81) du conduit le long de la portion (P) est inférieur au rayon (Rext,comp) de la paroi externe (81) du conduit à l'entrée (84) du compresseur (90).
