Abstract

A fuel injector for a gas turbine engine includes a housing (710) and a tube (708) defining a portion of a first fluid passage (702) therein and a second fluid passage (704) is defined between an exterior surface of the tube (708) and an interior surface of the housing (710). An inner airflow tube (712) is arranged having an inflow vane assembly (716) and a central air passage (706a). A portion of the first fluid passage (702) extends axially at a position radially outward from the inner airflow tube (712), and the third fluid passage (706a) extends axially at a position radially outward from the first fluid passage (702). A nozzle outlet (714) is configured to receive first, second, and thirds fluids from the respective fluid passages to cause mixing thereof. The inflow vane assembly (716) comprises a number of vanes, with each vane angled relative to a nozzle axis (F) at an angle between 20° and 40°.
