Abstract

La présente invention porte sur un moteur à turbine à gaz multiflux comprenant un compresseur et au moins une porte de décharge (30) en aval du compresseur, pivotant autour d'un axe aval (31), transversal par rapport à l'axe du moteur, caractérisé par le fait que la porte de décharge (30) comprend sur un seul côté longitudinal, sur au moins une partie de la longueur de ce dernier, une portion de paroi radiale (30L), parallèle à l'axe du moteur, ledit côté étant aval par rapport à la composante tangentielle de l'écoulement sortant du compresseur.
