Abstract
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.
