Abstract:
A gas turbine engine is piloted with a pilot flow of fuel delivered to a combustor (20) as a liquid. A first additional flow of the fuel is also delivered to the combustor (20) as a liquid. A second additional flow of the fuel is vaporized and delivered to the combustor (20) as a vapor. A fuel injector (40) has passageways associated with each of the three flows. The pilot fuel passageway extends from an inlet 68 to at least one outlet aperture (80). The additional liquid fuel passageway extends from an inlet 70 to a plurality of outlet apertures (82) arranged outside said outlet aperture (80). The vapor fuel passageway extends from an inlet 72 to a plurality of outlet apertures (84) arranged outside said liquid fuel outlets (82).
