초록 ▼

A mixer for use in a combustion chamber of a gas turbine engine. The mixer includes a first fuel injector adapted for dispensing droplets of fuel during ignition and low power settings of the engine and a pilot swirler positioned upstream from the first fuel injector. The pilot swirler has a plurality of vanes for swirling air to mix air and the droplets of fuel. The mixer also includes a second fuel injector adapted for dispensing droplets of fuel during high power settings of the engine and a main swirler adjacent the pilot swirler and upstream from the second fuel injector. The main swirler has a plurality of vanes for swirling air traveling through the main swirler to mix air and the droplets of fuel dispensed by the second fuel injector. The mixer also includes a barrier positioned between the pilot swirler and main swirler for separating the first fuel injector from the second fuel injector.

1. A mixer for use in a combustion chamber of a gas turbine engine, said mixer comprising:a first fuel injector adapted for dispensing droplets of fuel during ignition and low power settings of the engine; a pilot swirler positioned upstream from said first fuel injector having a plurality of vanes for swirling a first volume of air traveling through said pilot swirler to mix said first volume of air and the droplets of fuel dispensed by said first fuel injector to form a first fuel-air mixture selected for optimal burning during ignition and low power settings of the engine; a second fuel injector adapted for dispensing droplets of fuel during high power settings of the engine; a main swirler surrounding said pilot swirler and upstream from said second fuel injector having a plurality of vanes for swirling a second volume of air traveling through said main swirler to mix said second volume of air and the droplets of fuel dispensed by said second fuel injector to form a second fuel-air mixture selected for optimal burning during high power settings of the engine; and an annular barrier positioned between said pilot swirler and said main swirler for separating said first fuel injector from said second fuel injector, said barrier defining a pilot mixing chamber downstream from said pilot swirler and partially defining an annular main mixing charter downstream from said main swirler.
