Abstract

The system has a support unit (140) for supporting and centering a head (130) of a fuel injector. A truncated mixing bowl (142) is arranged downstream of the support unit. A radial swirler (134) is located between the support unit and the bowl. The swirler includes blades (180) defining radial channels for passage of air flow. The channels are contained within a radial plane. Trailing edges (178) of the blades extend on a widened truncated surface around a longitudinal axis of the system. The swirler includes a cylindrical peripheral edge (189) fixed on a venturi nozzle (138).
