Title (EN) DIVOT FOR OUTER CASE SHROUD
(FR) ÉVIDEMENT POUR CARÉNAGE EXTÉRIEUR DE CARTER
Abstract:
(EN) The invention concerns a turbine exhaust casing (TEC) for a gas turbine engine in which portions of the inner surface of the casing against which exhaust gas flows are provided with recesses extending into the surfaces. The recesses are positioned proximate to the leading edges of struts which extend between an outer shroud and inner hub of the casing.
(FR) L'invention concerne un carter d'échappement de turbine (TEC) pour un moteur à turbine à gaz dans lequel des parties de la surface interne du carter contre lesquelles s'écoulent les gaz d'échappement sont pourvues d'évidements s'étendant dans les surfaces. Les évidements sont positionnés à proximité des bords d'attaque des entretoises qui s'étendent entre un carénage extérieur et un moyeu intérieur du carter.
