Injection Element

Abstract: The invention relates to the field of injection elements (201) for injecting two propellants (E1 E2) into a combustion chamber especially designed for a rocket engine having at least one combustion chamber of the type comprising an injector combining at least one such injection elements (201). Such an injection element (201) comprises a first annular conduit (206) for injecting a first propellant (E1) and a second annular conduit (207) for injecting a second propellant (E2) the second conduit (207) being coaxial and outwardly adjacent to the first conduit (206) and potentially a third coaxial annular conduit (208) that is outwardly adjacent to the second conduit (207). The first conduit (206) surrounds a central body (205) of the injection element (201) said central body (205) comprising a cavity (209) that communicates with an outer surface (212) of the central body (205) and is designed so as to dampen at least one predetermined acoustic frequency f.
