Hypersonic weapons promise unmatched speed and reach, but they are held back by a fundamental engineering problem: propulsion ...

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 ...

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) ...

For years, the United States has trailed behind Russia and China in hypersonic weapons. A new engine prototype by Lockheed Martin and General Electric could help it catch up.

There have been published papers by the Air Force Research Lab and NASA on rotating detonation engines having 10% or more efficiency gains. A rotating detonation engine (RDE) uses a form of pressure ...

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.

IAN Alpha Fund on Wednesday said it has invested Rs 25 crore in D-Propulse Aerospace. The firm plans to use the seed capital ...

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 ...

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 ...

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 ...
