ABSTRACT:
An injection head for the combustion chamber of a rock propulsion unit has a base area with a plurality of injection elements distributed on it. Propellant constituents can be injected from each outlet of the injection elements into the combustion chamber, generating hot gases by a mixing and combustion of the propellant constituents in the combustion chamber, which hot gas can be accelerated to a high velocity for generating thrust. The base area of the injection head had a contoured shape which prevents or reduces the formation of zones of a reduced pressure, particularly between directly adjacent outlets.
