Title
(EN) ADDITIVE MANUFACTURED FUEL NOZZLE CORE FOR A GAS TURBINE ENGINE
(FR) ÂME DE GICLEUR DE CARBURANT À FABRICATION ADDITIVE POUR UN MOTEUR À TURBINE À GAZ
Abstract
(EN) A method of manufacturing a fuel component for a gas turbine engine combustor includes additive manufacturing a sacrificial core and manufacturing a fuel component body at least partially around the sacrificial core. The sacrificial core is at least partially removed to at least partially define an internal geometry of the fuel component. An additively manufactured sacrificial core for a fuel component of a gas turbine engine combustor includes a first structure and a second structure. The first structure at least partially defines a first passage of the fuel component. The second structure at least partially defines a second passage of the fuel component. The second structure at least partially surrounds the first structure.
(FR) L'invention concerne un procédé de fabrication d'un composant de carburant pour une chambre de combustion de moteur à turbine à gaz, comprenant la fabrication additive d'une âme sacrificielle et la fabrication d'un corps de composant de carburant au moins partiellement autour de l'âme sacrificielle. L'âme sacrificielle est au moins partiellement éliminée pour délimiter au moins partiellement une géométrie interne du composant de carburant. Une âme sacrificielle par fabrication additive pour un composant de carburant d'une chambre de combustion de moteur à turbine à gaz comprend une première structure et une seconde structure. La première structure délimite au moins partiellement un premier passage du composant de carburant. La seconde structure délimite au moins partiellement un second passage du composant de carburant. La seconde structure entoure au moins partiellement la première structure.
