Like much in life, the difference between detonation and pre-ignition, and their effects, comes down to timing. Both refer to a situation when an engine's fuel/air mixture combusts at the wrong time, ...

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

The two companies showed how a liquid-fueled rotating detonation ramjet, paired with a new tactical inlet, could tackle one ...

The compact, liquid-fuelled ramjet engine uses a novel combustion technology called rotating detonation that offers ...

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

A Florida team working with the US Air Force claims that it's built and tested an experimental model of a rotating detonation rocket engine, which uses spinning explosions inside a ring channel to ...

(RTTNews) - RTX Corp. (RTX), an aerospace and defense company, announced on Wednesday that its unit Raytheon has bagged a contract from the Defense Advanced Research Projects Agency or DARPA to ...

Engines that convert chemical energy from fuel into kinetic energy via explosive detonation, rather than slower deflagration combustion as seen in typical internal combustion engines. Categories ...

I recently got asked about what "pinging" is, and what the difference is between pre-ignition and detonation, what causes it, and why it is bad for an engine. Basically, both pre-ignition and ...

Dear Doctor: My 2015 Ford Fusion with the 2.0-liter turbocharged engine is at the local Ford dealership for a new engine, due to a piston breaking from a low speed pre-ignition incident. Luckily, the ...

A new rotating detonation engine could revolutionize rocket launches—if it can be made stable enough. That’s a big “if,” and one that researchers are hoping to explore using a new mathematical model ...
