Abstract

L'invention propose une Turbomachine (10) à double flux présentant un axe principal A et comportant une soufflante d'entrée (18) traversée par un flux d'air entrant (16) qui alimente une veine primaire (28) et une veine secondaire (30), dans laquelle la veine primaire (28) et la veine secondaire (30) sont concentriques à l'axe principal A, la veine primaire (28) étant radialement interne par rapport à la veine secondaire (30), dans laquelle la soufflante d'entrée (18) comporte un rotor de soufflante (32) portant une pluralité d'aubes mobiles (34), caractérisé en ce qu'au moins une aube mobile (34) comporte au moins un conduit interne (44) dont une première extrémité (46) débouche dans une partie radialement externe (42) du flux d'air entrant (16) et dont une deuxième extrémité (48) du conduit interne (44) débouche dans une partie radialement interne (40) du flux d'air entrant (16).
