Abstract

L'invention concerne le domaine des injecteurs, et en particulier un élément d'injection (201) d'un mélange d'au moins un premier ergol (E1) et un deuxième ergol (E2) dans une chambre de combustion (6), comprenant au moins un premier canal (204) pour l'injection du premier ergol (E1), et au moins un deuxième canal (205) pour l'injection du deuxième ergol (E2). Le deuxième canal (205) est un canal hélicoïdal suivant une hélice (205a) centrée sur un axe central (X) de l'élément d'injection (201). Un pourtour entier d'une section du deuxième canal (205) dans au moins un plan perpendiculaire à l'axe central (X) du premier canal (204) est formé dans une seule pièce monobloc.
