Abstract
Injection element of coaxial design for rocket combustion engines and for operation with two propellants, at least one of which disintegrates into drops with difficulty only, comprising a central body for the more readily disintegrating propellant (oxidant), whose flow channel generates a conical drop distribution at the outlet; a sleeve concentrically surrounding the central body to form an annular flow channel for the less readily disintegrating propellant (fuel); and a flow splitter which splits this propellant flow into a plurality of individual flows. The flow splitter has an even number of passage channels, which are uniformly distributed around the central body and cooperate in pairs in terms of an impact atomization ('impinging'), wherein the axes of two adjacent passage channels each intersect downstream of the flow splitter and upstream of their points of impact on the propellant cone discharged from the central body.
