Abstract

Elément d'injection (100) pour l'injection d'au moins deux ergols, comprenant deux canaux d'injection (18, 19) configurés pour injecter chacun des ergols de manière sensiblement axiale, ainsi qu'au moins une cavité de modulation (14) configurée pour recevoir l'un des ergols par au moins un orifice d'entrée (12), au moins un canal de mise en vitesse (16) relié à la cavité de modulation (14), et un obturateur (20) monté mobile dans la cavité de modulation (14), l'obturateur (20) étant configuré pour moduler une section du canal de mise en vitesse (16) en fonction de la pression de l'ergol dans la cavité de modulation (14). Tête d'injection et ensemble de combustion comprenant un tel élément d'injection.
