Suddenly, there's a flash of intense light and heat, followed by a rapidly expanding fireball. Combustion of high explosives is everywhere in popular culture, and it's also critical for ensuring the ...

Detonation combustion achieves near-constant-volume burning, drastically reducing entropy generation and wasting less energy as heat compared to traditional deflagration propulsion. Its supersonic ...

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, ...

Researchers have theoretically linked ignition and deflagration in a combustion system, unlocking new configurations for stable, efficient combustion engines due to the possible existence of any ...

Science, founded by Thomas A. Edison in 1880 and published by AAAS, today ranks as the world's largest circulation general science journal. Published 51 times a year, Science is renowned for its ...

This summary provides an elucidation of the complex processes underlying flame acceleration and the subsequent transition to detonation in combustion systems. Flame acceleration, a phenomenon in which ...

So the ram-rotor controls reactant compression, the detonation point, and burned gas expansion within that single rotor. And it uses a continuous supersonic rotating detonation wave as its primary ...

Last year, the Defense Advanced Research Projects Agency (DARPA) quietly unveiled a new high-speed missile program called Gambit. The program is meant to leverage a novel method of propulsion that ...

The Rotating Detonation Engine being developed by Pratt & Whitney has no moving parts, which reduces complexity and costs, and could help enable high-speed, long-range flight with increased efficiency ...

Cars make odd noises sometimes, letting you know it's time to have it serviced. If there's a metallic knocking noise, it ...
