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 ...

GE Aerospace says it successfully demonstrated an advanced jet propulsion concept that involves a dual-mode ramjet design utilizing rotating detonation combustion. This could offer a pathway to the ...

Rotating detonation engine could be up to 25% more efficient than traditional jet engines. This could make airplanes and missile faster or with longer range. Smaller weapons could reach the same ...

GE and Lockheed Martin plan to get around this by accelerating the missile using a rotating detonation engine, which uses a supersonic wave of detonating fuel that runs about inside an open-ended ...

A startup high-speed flight company from Houston, Texas, has successfully tested its Rotating Detonation Rocket Engine (RDRE) ultimately aimed at allowing travel at four to six times the speed of ...

DARPA has contracted Raytheon to develop a practical version of a revolutionary air-breathing rotating detonation engine called Gambit, which would have no moving parts and could lead to lighter ...

The main problem holding back reusable hypersonic planes is that traditional ramjet engines become very inefficient over mach 2 while hypersonic engines do not work well below mach 4. There is the ...

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 ...

Lehigh University researcher Natasha Vermaak leads multidisciplinary project— supported by a new $2 million NSF grant—investigating rotating detonation engine materials The ability to reliably order ...

Researchers at Purdue University's College of Engineering are conducting tests on a patented Tesla valve-inspired injection manifold design to improve the efficiency of rotating detonation engines ...

Looks to replace its gas turbine engines with rotating detonation versions. There are also paragraphs in various Rocket Report articles. All that said, I'd certainly welcome a new Ars deep dive into ...

Soon, America’s older warbirds could see their claws sharpened significantly, as it was announced in October that Raytheon Missiles and Defense had been selected to build and demonstrate a ...
