An injector element for injecting a mixture of at least a first propellant and a second propellant into a combustion chamber. The injector element includes a first tubular wall defining a first duct for injecting the first propellant, and a second wall surrounding the first wall and defining, between the first and second walls, a second duct for injecting the second propellant. The first wall includes a first electrode for igniting the mixture by electric discharge.

Injection element having an ignition device

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.

Propellant injector allowing propellant to be discharged while ensuring uniform injection

An injector for mixing two propellants upstream of a combustion chamber. The injector includes: at least one injection element with a tricoaxial structure installed between two plates which between them delimit a space; and coaxial ducts including an internal coaxial duct and an external coaxial duct that are supplied in parallel with a same propellant, for example via the space.
