Abstract

La présente invention concerne un gicleur de carburant (10) pour un moteur de turbine à gaz comprenant un corps de gicleur (102) doté d'un axe longitudinal (122). Un passage d'air annulaire allongé (104) est défini à l'intérieur du corps de gicleur. Une pluralité d'aubes de turbulence (106) espacées dans le plan circonférentiel et s'étendant dans le plan axial sont disposées à l'intérieur du passage d'air annulaire. Chaque aube de turbulence est dotée d'un profil en coupe transversale axialement en flèche le long du prolongement radial de celle-ci.
