Quote:Rotating Detonation Engine (RDEs) were also defined as scramjets in a conference. However, I could not download the pdf version.
They are mostly applied for all kind of jet engines like ramjet, scramjet, turbine and rocket engines. Researches have been conducted with different combination of fuels like Hydrogen- Air, Hydrogen-oxygen etc to find the most efficient combination under laboratory conditions. Finally, the possible combination of engines is discussed.

“This technology can be applied to all kinds of jet engines like ramjet and scramjet.” This statement is important.
RDE produces axial and radial supersonic superheated airflow inside the combustion chamber. (A bit like the supersonic air passing through a scramjet). Normally it is a closed system. It does not need to breathe atmosphere. But the technique, theoretically, can be used to overcome some of the limitations of scramjets, ramjets, turbine and rocket engines. I can concur with that. But Rotating Detonation Engine is not a scramjet. The technology can be used in a scramjet as it is more efficient and has similarities. The technology, can also be used to improve efficiency and power of turbine engines.
It seems that Roketsan is actually working on a revolutionary space rocket engine with RDE. This is big!
