Abstract
An injector of a propellant combustion member, the injector including a first feed and a second feed; the first feed being connected to a plurality of feed chimneys arranged around a longitudinal axis; the second feed being configured so as to feed an injection chamber; and the injection chamber being connected to a plurality of feed sheaths with injection orifices, each feed chimney being surrounded by a coaxial feed sheath; the injector including a takeoff chamber connected to a takeoff duct for taking off the second propellant, the takeoff chamber being arranged in such a manner as to take off the second liquid propellant from the injection chamber; and it is configured to achieve uniform injection of the second propellant via the injection orifices.
