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 ...

Pratt & Whitney is planning further development of rotating detonation engine (RDE) technology following “positive test results” from a series of ground tests. The work, which was completed with the ...

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 ...

On May 14, 2025 Venus Aerospace became the first in the world to successfully fly a high-thrust rotating detonation rocket engine (RDRE) — achieving what no government or private entity had done ...

Craig Nordeen (Air Force Research Lab, Pratt & Whitney) gives a lesson from three years ago on detonation engines. He describes the history and how they work and why they are more efficient. The work ...

Essentially, it's a rotating detonation engine in which the detonation wave is stabilized within a high-speed rotor. A precisely shaped flow channel within the rotor compresses the air-fuel mixture to ...

The U.S. Naval Research Laboratory (NRL) is researching the possibility of using Rotating Detonation Engines (RDEs) to reduce fuel consumption in gas-turbine engines, says Kazhikathra Kailasanath, who ...

Ars Technica has been separating the signal from the noise for over 25 years. With our unique combination of technical savvy and wide-ranging interest in the technological arts and sciences, Ars is ...

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 ...

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 ...

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, ...
