INJECTION SYSTEM FOR A TURBOMACHINE, COMPRISING A SPINDLE AND SWIRLING BOWL MIXER HOLES

摘要

The invention relates to an injection system (4) for a turbomachine combustion chamber. The injection system (4) includes a spinner (7) and a mixing bowl (8). The mixing bowl (8) comprises a converging frustoconical portion (82) and a diverging frustoconical portion (84). The divergent frustoconical portion (84) is connected to the converging frustoconical portion (82) by forming an airfoil continuity with the converging frustoconical portion (82). The divergent frustoconical portion (84) is crossed by vortex holes (81) which each comprise a circumferential component around a longitudinal axis (XX) of the injection system and an axial component along the longitudinal axis (XX) of the system. injection.
