Multiple injector combustor

A mixer for use in a combustion chamber of a gas turbine engine, said mixer comprising:

• an annular housing having an upstream end, a downstream end opposite said upstream end, a mount for attaching the housing to an upstream end of the combustion chamber, and an interior surface defining a hollow interior, the interior surface of the housing including a plurality of holes for introducing air to the combustion chamber;
• a first swirler mounted inside the annular housing including a plurality of vanes extending inward from the housing for swirling air traveling through the housing from the upstream end to the downstream end;
• an annular fuel injector having a plurality of fuel injection ports arranged in a generally circular pattern mounted inside said first swirler for releasing droplets of fuel into swirling air downstream from said fuel injector;
• and
• a second swirler mounted inside the fuel injector including a plurality of vanes extending inward from the injector for swirling air traveling through the housing downstream from the fuel injector.
