Abstract
Fuel injectors for gas turbine engines include a housing and a tube defining a portion of a first fluid passage therein and a second fluid passage is defined between an exterior surface of the tube and an interior surface of the housing. An inner airflow tube is arranged having an inflow vane assembly and a central air passage. A portion of the first fluid passage extends axially at a position radially outward from the inner airflow tube, and the third fluid passage extends axially at a position radially outward from the first fluid passage. A nozzle outlet is configured to receive first, second, and thirds fluids from the respective fluid passages to cause mixing thereof. The inflow vane assembly comprises a number of vanes, with each vane angled relative to a nozzle axis at an angle between 20° and 40°.
