Abstract
The fuel injector for a combustor of a gas turbine engine of the high shear design type is configured to include two swirlers with passages where the vanes in the inner swirler of the inner swirler in the passage which is closest to the centerline of the fuel nozzle includes a judiciously located twist and together with the proper flow ratio between the two swirl passages and the proper swirl angle of the flow stream in each of the passages provide an enhanced fuel injector with improved lean blowout and high altitude relight characteristics while assuring a stable recirculation region in the combustion zone.
