GE and Lockheed Martin have demonstrated a new rotating detonation engine ramjet design in a series of tests that show significant potential for efficiency gains. If developed into a full missile ...

EAST HARTFORD, Conn., March 4, 2025 /PRNewswire/ -- Pratt & Whitney, an RTX (RTX) (NYSE: RTX) business, has completed a series of tests on its rotating detonation engine (RDE) work with the RTX ...

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 ...

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, ...

Rotating Detonation Engines (RDE) have been flown by Venus Aerospace. They use continuous detonation waves for propulsion and provide 15% efficiency gains (in specific impulse or fuel consumption) ...

More than 60 years ago, scientists in the United States imagined a powerful engine that could push aircraft to hypersonic speeds—up to 16 times the speed of sound. This dream involved something called ...

There probably never was a better time for rocket engine fans to be alive. It's a time when those who have the means can go out and start building the rocket engine of their dreams, while the rest can ...

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 ...

A new type of rocket engine, one that could power a plane from Los Angeles to Tokyo in just two hours, has eluded scientists for decades. Houston’s Venus Aerospace says it recently solved the puzzle.

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 ...

Chinese scientists have once again innovated a new technology—and not just any technology, but an extraordinary new engine that could improve rotating detonation engines. It could have profound ...

I assume that if the detonation/flame front is itself rotating within the combustion chamber/channel/however one chooses to contain and direct it, then the expanding shockwave from the exhaust plume ...
