  • Fuel injector with first and second converging fuel-air passages
    Patent number: 9423137
    Abstract: A gas turbine engine fuel injector is disclosed having a plurality of fuel injection circuits that are structured to deliver fuel to air passageways. In one non-limiting embodiment, one of the fuel injection circuits includes a plain jet airblast injector that delivers fuel to an air passageway. In some applications the plain jet can extend across the air passageway and deliver a fuel to an opposite surface to form a fuel film. The fuel film can then be sheared between an air in the air passageway and an air in a nearby air passageway. Another of the fuel injection circuits includes a fuel filmer structured to deliver fuel to an air passageway that can then be sheared by an air in the air passageway and an air in the air passageway that included the plain jet airblast injector.
