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

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.

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

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 ...

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 ...

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" ...

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

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

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 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 ...
