Abstract
A fuel nozzle for a gas turbine engine that includes: an elongated centerbody; an elongated peripheral wall formed about the centerbody so to define a primary flow annulus therebetween; a primary fuel supply and a primary air supply in fluid communication with an upstream end of the primary flow annulus; and a pilot nozzle. The pilot nozzle may be formed in the centerbody and include: axially elongated mixing tubes defined within a centerbody wall; a fuel port positioned on the mixing tubes for connecting each to a secondary fuel supply; and a secondary air supply configured so to fluidly communicate with an inlet of each of the mixing tubes. A plurality of the mixing tubes may be formed as canted mixing tubes that are configured for inducing a swirling flow about the central axis in a collective discharge therefrom.
