Abstract

Turbomachine (1) comprenant une veine primaire (27), une veine secondaire (26) située radialement à l’extérieur de la veine primaire (27) de sorte à entourer la veine primaire (27), un compresseur (4) s’étendant dans la veine primaire, une vanne de sortie (49) configurée pour contrôler une alimentation en air d’un système de contrôle de l'environnement, et une turbine auxiliaire (52) configurée pour être alimentée en air issu du compresseur (4), une sortie (54) de la turbine auxiliaire (52) étant sélectivement raccordée fluidiquement à la veine secondaire (26) ou à la vanne de sortie (49). Figure pour l’abrégé : Fig. 2A turbomachine (1) comprising a primary vein (27), a secondary vein (26) located radially outside the primary vein (27) so as to surround the primary vein (27), a compressor (4) extending into the primary vein, an outlet valve (49) configured to control an air supply to an environmental control system, and an auxiliary turbine (52) configured to be supplied with air from the compressor (4), an outlet (54) of the auxiliary turbine (52) being selectively fluidically connected to the secondary vein (26) or to the outlet valve (49).
