ABSTRACT:
The fuel nozzle is configured with a fuel injector with a pair of coaxially mounted air swirlers utilized in an annular combustor of a gas turbine engine that is dimensioned to provide 70-90 percent of the mass airflow in the inner passage and the swirl angle of the inner swirler is 45.degree.-55.degree. and the outer swirler is 70.degree. and the L/D of the combustion hole location relative to the fuel injector is 0.6-0.7 which serve to produce an outer shear layer flame for improved lean blowout characteristics.
