Abstract:
Metallic atomic hydrogen (MAH) – if it is metastable – has the potential to be a revolutionary rocket propellant with outstanding specific impulse. This paper discusses the likely limits of MAH metastability, and how these can be accommodated with suitable micro-composite engineering to maintain high pressure containment of the MAH. Manufacturing of MAH is discussed, as well as the form of a suitable rocket engine employing MAH.
