Abstract

L'invention concerne un déflecteur de flux (4) d'un système de vanne de décharge (1) d'un compresseur de turbomachine double flux, le déflecteur de flux comprenant une paroi (5) pourvue d'une pluralité de canaux d'éjection (6) aptes à décharger un flux d'air de décharge (Fc) du compresseur dans une veine (V1, V2) de la turbomachine (100) dans laquelle circule un flux d'air (F). Selon l'invention, les canaux d'éjection (6) sont disposés suivant plusieurs rangées concentriques autour d'un centre (A) et orientés suivant un angle (α) défini entre une droite normale (D) à la paroi (5) et les axes (C) des canaux d'éjection (6), et variant en croissant du bord périphérique (15) vers le centre (A) de la paroi (5) de manière que le flux d'air de décharge (Fc) traversant les canaux d'éjection (6) soit guidé suivant un mouvement giratoire autour du centre (A).
