<p>A mixer (50) for use in a combustion chamber of a gas turbine engine. The mixer (50) includes an annular housing (52) having an upstream end (54), a downstream end (56), a mount (58) for attaching the housing to an upstream end of the combustion chamber (32), and an interior surface (90) defining a hollow interior. The mixer (50) also has a first swirler (60) mounted inside the annular housing (52) including a plurality of vanes (62) extending inward from the housing (52) for swirling air traveling through the housing (52). In addition, the mixer (50) includes an annular fuel injector (66) having a plurality of fuel injection ports (68) arranged in a generally circular pattern mounted inside the first swirler (60) for releasing droplets of fuel into swirling air downstream from the fuel injector (66). Further, the mixer (50) has a second swirler (80) mounted inside the fuel injector (66) including a plurality of vanes (82) extending inward from the injector (66) for swirling air traveling through the housing (52) downstream from the fuel injector (66). <IMAGE></p> |
