Abstract

Ensemble de turbomachine 10) comprenant un compresseur centrifuge (11) avec un rotor (50) à double rouets agencés selon une configuration dos-à-dos, et un diffuseur (12) agencé en vis-à-vis radial de la sortie (13) du rotor (50) à double rouets, dans lequel le diffuseur (12) comprend des moyens de séparation (14) de l’air sortant du compresseur centrifuge (11) agencés de sorte qu’un premier flux d’air sortant d’un premier rouet (15) alimente un premier conduit annulaire (16) du diffuseur (12) et qu’un second flux d’air sortant d’un second rouet (17) alimente un second conduit annulaire (18) du diffuseur (12).
