  • "Scramjet is a very handy semi-acronym, standing for Supersonic Combustion Ramjet. In layman's terms this amounts to an engine with a forward vent that scoops in air as it travels through the atmosphere. The air is compressed through narrowing chambers (and therefore heated), before being mixed with hydrogen. This combination combusts, emitting an exhaust through a rearward nozzle and producing enough thrust to reach hypersonic speeds of between Mach 7 (seven times the speed of sound) and maybe as high as Mach 18, leaving nothing more toxic in the air than a trail of water vapour, for the most part."
