An improved airblast fuel injector for a gas turbine engine wherein the injector comprises an inner air discharge chamber, a first fuel discharge chamber disposed outboard of the inner air chamber, an intermediate air discharge chamber disposed radially outboard of the first fuel chamber, a second fuel discharge chamber disposed radially outboard of the first outer air chamber, and an outer air discharge chamber disposed radially outboard of the second fuel chamber. The fuel flow from the first fuel discharge chamber is subjected to inner and outer atomizing air flows from the inner and intermediate air chambers. The fuel flow from the second fuel discharge chamber is subjected to inner and outer atomizing airflows from the intermediate and outer air discharge chambers. The individual fuel flow streams discharged from the first and second fuel discharge chambers provide an aggregate, high mass flow of fuel necessary for engine operation. The individual, atomized fuel flow streams discharged from the injector face are blended together downstream of the discharge face.
