Researchers in China have introduced a new hypersonic engine concept by integrating a ramjet with a rotary detonation engine. A team at Tsinghua University in Beijing created a new design known as the ...

GE and Lockheed Martin plan to get around this by accelerating the missile using a rotating detonation engine, which uses a supersonic wave of detonating fuel that runs about inside an open-ended ...

Engine knocking, or detonation, occurs when fuel in the cylinders ignites unevenly, causing metallic pinging sounds, reduced power, and potential engine damage. Key causes include low-octane fuel, ...

For years, the United States has trailed behind Russia and China in hypersonic weapons. A new engine prototype by Lockheed ...

I assume that if the detonation/flame front is itself rotating within the combustion chamber/channel/however one chooses to contain and direct it, then the expanding shockwave from the exhaust plume ...
