Abstract

L’invention concerne un déflecteur de flux (21) d’un compresseur de turbomachine (1) à double flux d’axe longitudinal, le déflecteur de flux comprenant une paroi (25) pourvue d’une pluralité de canaux d’éjection (29) aptes à décharger un flux d’air de décharge dans une veine de la turbomachine dans laquelle circule un flux d’air, les canaux d’éjection d’axes (C) étant agencés en plusieurs rangées et étant configurés de manière à éjecter le flux d’air de décharge suivant la direction d’écoulement du flux d’air, les axes (C) étant chacun orienté suivant une première direction formant un premier angle (α) par rapport à un axe (B) parallèle à un axe de révolution du déflecteur de décharge. Selon l’invention, la projection des axes des canaux d’éjection (29) de chaque rangée dans un plan de projection (PP) perpendiculaire au plan médian (PM) forme un deuxième angle (β) avec une droite parallèle au plan médian.
