Abstract (en)
A combustor for a gas turbine engine has a head end portion that carries at least one fuel/air nozzle (12). Each fuel/air nozzle (12) includes a premixed pilot nozzle (40) having premix conduits (41) that are configured with concentric axes that direct the fuel/air mixture axially from the premixed pilot nozzle (40). The premixed pilot nozzle (40) can include an annular channel (70) disposed radially outwardly from the premix conduits (41) and including air jets (61) that direct air radially outwardly from the premix conduits (41).
