Supersonic combustion is used to propel hypersonic scramjets, which travel at speeds over Mach 5. These engines are ...

Supersonic combustion and scramjet engine dynamics represent a frontier in aerospace propulsion, offering a pathway to ultra‐high-speed flight through the efficient combustion of fuel in a supersonic ...

NASA built an X-42A hydrogen-powered scramjet to reach speeds of Mach 9.6 for a brief moment in 2004. Therefore, this new unmanned aircraft would be more of an optimization and refitting of an ...
