Abstract

La couronne d’injecteurs de turbine est traversée par des canaux (20) formant des injecteurs et présentant chacun un tronçon principal (38) s’étendant dans un plan (P) perpendiculaire à un axe principal (X-X) de la couronne.Chaque canal présente une embouchure d’entrée (32) et une embouchure de sortie (34) située plus près de l’axe (X-X) que l’embouchure d’entrée.L’embouchure d’entrée (32) prolonge le tronçon principal (38) dans une direction inclinée par rapport à une direction radiale à l’axe (X-X).
