The world's first hydrogen-fueled hypersonic jet may be able to reach a simply astounding speed of 12 times the speed of ...

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 ...

Key Points and Summary - NASA’s X-43A wasn’t a paper study—it was a 12-foot, hydrogen-fueled experimental jet that proved an air-breathing engine could fly at nearly ten times the speed of sound. -It ...

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 ...
