Hi, I wonder why the Black Knight creators used steel for the tubes, which made the chamber wall of their engines. The steel is certainly more sturdy, than copper, however, the copper is considered the material of choice for the chamber wall because thermoconductivity benefits outweight the disadvantage in construction strength. However, in this particular case - peroxide engines - there is an additional problem of compatibility. OTOH, the (in)compatibility problem can be handled with inner coating - not too thick, to maintain a good thermoconductance, and not too thin, to shield the peroxide from the copper walls. Have anybody pursued such a path?
