Abstract
A method for fabricating a main body of a trapped vortex fuel injector having a main body defining a fuel circuit. The method includes determining three-dimensional information of the main body including the fuel circuit where the fuel circuit is fully circumscribed within the main body and extends between an annular portion and a semi-annular portion of the main body and where the three-dimensional information of the main body further includes a plurality of fuel injection ports which provide for fluid communication between the fuel circuit and a trapped vortex pre-mix zone. The method further includes converting the three-dimensional information into a plurality of slices that define a cross-sectional layer of the main body and successively forming each layer of the main body by fusing a metallic powder using laser energy or electron beam energy.
