C, was an ambitious experimental hypersonic aircraft project in the 1970s that aimed to build upon the advancements of the ...

At lower speeds, the incoming air pressure is insufficient for scramjet performance. As such, scramjets are generally used at ...

And since a plane moving at scramjet speeds will be seared by the heat of friction as it moves through the atmosphere, the frigid hydrogen will make an ideal coolant to be pumped through the skin ...

But at least in the near term, the most likely application for hypersonic scramjet engines isn’t a plane. Boeing X-51 Waverider mounted to the wing of a B-52 Aerojet Rocketdyne and Northrop ...
