On January 14, GE Aerospace and Lockheed Martin revealed the results of a new ...

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

The compact, liquid-fuelled ramjet engine uses a novel combustion technology called rotating detonation that offers significantly improved efficiency for high-speed flight at Mach 5 and beyond.

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 ...

Combining the technologies could improve efficiency enough to make hypersonic projectiles much more affordable.

GE and Lockheed ground tested a new air-breathing hypersonic jet engine capable of powering missiles to speeds well in excess ...

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 ...

GE Aerospace and Lockheed Martin completed a series of engine tests demonstrating the viability of a liquid-fueled rotating ...

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 ...

A US-based propulsion company has successfully launched and flown a new rocket powered by a unique rotating detonation engine. Although relatively small by rocket standards, the test could pave the ...

Engine knocking, or detonation, occurs when fuel in the cylinders ignites unevenly, causing metallic pinging sounds, red ...

A series of tests have demonstrated the viability of a liquid-fueled rotating detonation ramjet for hypersonic missiles, ...
