Mixer having multiple swirlers

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

• a pilot mixer including an annular pilot housing having a hollow interior, a pilot fuel nozzle mounted in the housing and adapted for dispensing droplets of fuel to the hollow interior of the pilot housing, and a plurality of axial swirlers positioned upstream from the pilot fuel nozzle, each of said plurality of swirlers having a plurality of vanes for swirling air traveling through the respective swirler to mix air and the droplets of fuel dispensed by the pilot fuel nozzle;
• and
• a main mixer including a main housing surrounding the pilot housing and defining an annular cavity, an annular fuel injector having a plurality of fuel injection ports arranged in a circular pattern surrounding the pilot housing and mounted inside the annular cavity of said main mixer for releasing droplets of fuel into swirling air downstream from the fuel injector, and a plurality of swirlers positioned upstream from the plurality of fuel injection ports, each of said main mixer swirlers having a plurality of vanes for swirling air traveling through the respective swirler to mix air and the droplets of fuel dispensed by the fuel injection ports, at least one of said main mixer swirlers and at least one of said pilot mixer swirlers being coaxial.
