MULTITUBE PILOT INJECTION INTO TRAPPED VORTICES IN A GAS TURBINE ENGINE
A combustor of a gas turbine engine is provided with a first injector and a second injector. The first injector surrounds a combustion liner and is positioned at a downstream end of a flow sleeve. A dome plate is positioned to receive a fuel/air mixture from the first injector and turn it 180 degree...

| description | A combustor of a gas turbine engine is provided with a first injector and a second injector. The first injector surrounds a combustion liner and is positioned at a downstream end of a flow sleeve. A dome plate is positioned to receive a fuel/air mixture from the first injector and turn it 180 degrees to enter a combustion zone formed within the combustion liner. The second injector is positioned radially inward of the combustion liner at an inlet end of the combustion zone and receives only compressed air from the first injector. The second injector includes a plurality of air/fuel mixing tubes divided into radially outer and radially inner subsets of air/fuel mixing tubes with a first fuel manifold in fluid communication with the radially outer subset of air/fuel mixing tubes and a second fuel manifold in fluid communication with the radially inner subset of air/fuel mixing tubes. |
