Jet swirl air blast fuel injector for gas turbine engine

A fuel injector 300 for a gas turbine engine (10 Fig. 1) has an outer sleeve 310. An upstream end 99 of the outer sleeve defines an inlet opening 309 and a downstream end 98 defines an exit opening 311. The outer sleeve has a radial opening 313 extended therethrough along the radial direction. At least a portion of the outer sleeve has a plurality of grooves 315. A first member 323 of an arm 320 is coupled to the outer sleeve and a second member 325 of the arm is contoured defining a fuel injection port (327 Fig. 9) generally concentric to the fuel injector centreline 13. Additionally, the outer sleeve has a fuel conduit (319 Fig. 10) through at least a portion of the outer sleeve outward of the plurality of grooves along the radial direction from the fuel injector centerline. The second member of the arm may define a pressurised fuel atomizer.
