The scramjet — or "supersonic combustion ramjet" — engine is an innovation on the original ramjet engine design that changes the internal combustion chamber to remove the shock cones.

By 3D printing their scramjet engines, they can not only iterate through design revisions faster, but produce them far cheaper than they’ve been able to in the past. Even more importantly ...

China has tested a powerful engine that can carry weapons at remarkable speeds through both air and water. The novel engine achieved 90% efficiency in laboratory tests, which were conducted in ...

With handful of start-ups on board from Hermeus to Venus Aerospace, hypersonic commercial flights could soon become a reality ...

the research team has developed an innovative secondary combustion technique that nearly doubles the thrust of a scramjet engine by injecting magnesium powder into the exhaust gases from ...
