Abstract (en)
[origin: WO2012156631A1] Annular combustion chamber (10) for a turbomachine, comprising an annular row of fuel injectors (28) the tips (30) of which are engaged in fuel injection systems (126) mounted in openings (24) in the chamber end wall, each injector tip comprising at least one helical channel (42, 48) for carrying fuel in order to set this fuel in rotation about the longitudinal axis (XX) of the tip, and each injection system comprising at least one swirl inducer (154) the air passage channels (100) of which have cross sections the axes of which are inclined with respect to the longitudinal axis of the swirl inducer, by an angle (ß') that is substantially equal to the helix angle (ß) of the aforementioned helical channel, give or take 10°, and which are oriented in the same direction as this channel about the longitudinal axis of the swirl inducer.
