Regeneratively cooled combustion chamber - for rocket using storage-stable liquid fuel, with corrosion-resistant cooling channels

摘要

Regeneratively cooled combustion chamber for liquid-propelled rocket comprises a signlepiece body made of O2-free Cu, with cooling channels through which flow at least one fuel component. The channels are coated with galvanically deposited corrosion-resistant layers of Al at least 4 microns thick, or they may be made of corrosion-resistant steel, and are covered by an outer wall consisting of a thin galvanically deposited intermediate layer and a pressure jacket made of high-strength metal, e.g. ni, Cu or a Ni-Co alloy. The intermediate layer consists of Al which is cold-formed and/or dispersion-hardened and which has a thickness of at least 8 microns at least on the cooling side.
