A method for manufacturing a stem for a fuel injector of gas turbine engine includes forging a material into a unitary workpiece, which includes forging a top disk having a cylindrical shape, forging a body extending from a base of the top disk, and forging a lower disk connected to the body, distal to the top disk, the lower disk having a cylindrical shape oriented transverse to the top disk. The method further including machining the lower disk to form a gas gallery having a ring shape, and to define a gallery opening through the gas gallery, and machining a first fluid passage through the top disk, the body, and a portion of the gas gallery to the gallery opening, wherein the first fluid passage is in fluid communication with the gallery opening.

Forged fuel injector stem

A gas turbine engine fuel injector stem includes a single piece of material with a flange, a center body, a gas gallery, and a fluid passage. The flange includes a cylindrical shape, a plurality of mounting holes and a handle hole. The center body extends from a flange cap in the flange axial direction. The gas gallery is adjacent the center body and distal to the flange. The gas gallery includes a ring shape oriented transverse to the flange and includes a gallery opening. The fluid passage extends through the flange, center body, and gas gallery and is in flow communication with the gallery opening.
