Abstract: A process includes manufacturing a gas turbine fuel injector body having a stub flange extending radially outward about a circumference of the gas turbine fuel injector body. The stub flange is sized to engage a stepped ledge along a central opening of a mounting flange. The central opening is sized to receive the gas turbine fuel injector body. A gas turbine fuel injector includes a gas turbine fuel injector body and a mounting flange. A method of mounting a gas turbine fuel injector includes placing a stub flange of a gas turbine fuel injector body between a surface of an injector boss and a stepped ledge of a mounting flange. The method also includes securing the gas turbine fuel injector to the injector boss with a plurality of bolts, each bolt extending through a mounting hole in the mounting flange and into a threaded hole in the injector boss.

Abstract: A combustor assembly includes a combustion liner at least partially surrounded by a flow sleeve and an impingement sleeve and an axial expansion joint defined between an aft end of the flow sleeve and a forward end of the impingement sleeve. A radial fuel injector extends radially through the impingement sleeve and at least partially through the combustion liner and the radial fuel injector is fluidly coupled to a fuel conduit that extends across the expansion joint. The combustor assembly further includes an air shield assembly having a forward end slideably connected to the flow sleeve, an aft end rigidly connected to at least one of the combustion liner, the radial fuel injector and the impingement sleeve, and a bridge member. The bridge member at least partially encloses the fuel conduit and connects the forward end of the air shield assembly to the aft end of the air shield assembly.
