Abstract

A rocket propulsion unit with an outer casing and an inner casing is described whereby the inner casing is arranged with space between the outer casing, and the inner casing forms a combustion chamber and has a contour adapted to the expulsion of propellants out of the combustion chamber with a constriction for forming a combustion chamber neck. The outer casing in contrast has a contour deviating from the contour of the inner casing.
