The demon of engine knock is something an owner of a traditional high-performance Pontiac knows all too well. An engine designed when 102-octane high test was at almost every fuel station in 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 ...

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 ...

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

Two revolutionary aerospace technologies collide as GE Aerospace and Lockheed Martin team up to demonstrate a new liquid-fueled rotating-detonation ramjet (RDRJ) designed to close the "efficiency gap" ...

The rotating detonation rocket engine (RDRE) is the new Holy Grail of the aerospace industry. The way such a technology works promises unprecedented speeds for aircraft and spacecraft, prompting ...

A supersonic drone that will be propelled by a revolutionary new engine has taken to the skies for the first time. When Venus Aerospace's aircraft does go supersonic on a later date, it will be ...

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 ...

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 ...
