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

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 is a supersonic combustion wave, characterized by a shock wave driven by the energy release from closely coupled chemical reactions. It is a typical form of pressure gain combustion, ...

They're noisy, but your next missile or military vehicle might have an RDE (rotating detonation engine) powerplant in it. RDEs are more fuel-efficient, lighter, easier to maintain, and capable of ...

Chinese "Space Transportation" company, Lingkong Tianxing Technology, has successfully tested its new JinDou400, also known as JinDouyun, ramjet detonation engine nearly twice the altitude of ...

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 ...

Researchers from Tohoku University theoretically established a connection between ignition and deflagration in a combustion system, opening up new possibilities for stable, effective combustion engine ...

NASA’s Marshall Space Flight Center in Huntsville, Alabama, recorded ignition of a full-scale Rotating Detonation Rocket Engine combustor, which was fired for a record 251 seconds and achieved more ...

A new family of engines aims to harness the power of detonation shockwaves to create ever-faster rocket engines. One of these engines—known as a rotating detonation engine (RDE)—has shown some ...

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 ...

A US-based propulsion company, Venus Aerospace, said Wednesday it had completed a short flight test of its rotating detonation rocket engine at Spaceport America in New Mexico. The company’s chief ...

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 ...
