A mounting system for an annular internal fuel manifold disposed within a gas turbine engine includes a fuel inlet assembly having a heat shield extending about at least a portion of an inner fuel inlet tube. The heat shield has a distal end engaged with the fuel manifold and has a radially outwardly projecting shoulder proximate an opposed proximal end thereof. The proximal end of the heat shield is received within a bushing disposed within a corresponding opening of a supporting casing. The shoulder of the heat shield retains the bushing in place.
La présente concerne un système de fixation de rampe de distribution annulaire interne de carburant disposée dans un moteur à turbine à gaz, comprenant un ensemble d'admission du carburant ayant un bouclier thermique s'étendant sur au moins une partie de la tubulure interne d'admission de carburant. Le bouclier thermique a une extrémité distale engagée avec la rampe de distribution de carburant et a un épaulement radialement en saillie vers l'extérieur à proximité de l'extrémité proximale opposée de celui-ci. L'extrémité proximale du bouclier thermique s'insère dans une douille disposée dans une ouverture correspondante d'un cadre de soutien. L'épaulement du bouclier thermique maintient la douille en place.
