Abstract
An airblast atomizer with air swirl vanes has an outlet configured to produce a fuel/air mixture pattern from the fuel nozzle to match an annular combustion chamber formed between an annular inner combustor wall and an annular combustor wall having inlet ends thereof connected to an annular dome for supporting each of a plurality of the fuel nozzles; each of the nozzles including a pair of spaced, large radius slots in a cylindrical outlet wall of the nozzle operative to produce a vortex pattern that will spread the mixed fuel/air pattern from the nozzle to define the major axis of an elliptically formed fuel/air pattern from the nozzle and wherein the remainder of the airblast atomizer nozzle has a reduced radius to conform the fuel/air mixture to the diameter of an outlet swirl chamber from the nozzle to produce the minor axis of an elliptically configured fuel/air spray pattern and wherein the major axis is formed as a chordal line of the combustion chamber to conform the fuel/air mixture pattern from each of the fuel nozzles to the annular shape of the combustor chamber thereby to reduce the number of airblast atomizer fuel nozzles required to completely cover a predetermined diameter of combustion chamber annulus.
