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 ...

A self-propagating series of explosions, contained between the blades of a high-speed rotor, promises a leap in power and efficiency during hypersonic flight – provided this radical new engine can be ...

Two revolutionary aerospace technologies collide as GE Aerospace and Lockheed Martin team up to demonstrate a new liquid-fueled rotating-detonation ramjet (RDRJ) designed to close the "efficiency gap" ...

Venus Aerospace's rotating detonation rocket engine (RDRE). Houston, Texas-based Venus Aerospace, a hypersonics pioneer aimed at developing reusable hypersonic flight platforms, recently achieved one ...

Engine maker GE Aerospace and defence manufacturer Lockheed Martin have teamed up to test a novel ramjet propulsion system for powering hypersonic flight. The pair say they completed a series of ...

For years, the United States has trailed behind Russia and China in hypersonic weapons. A new engine prototype by Lockheed ...

The Hypersonic Dual-Mode Ramjet test, believed to be the first of its kind, exploited rotating detonation combustion technology. General Electric Aerospace announced a successful demonstration of ...

The rotary engine has been absent on the frontline for quite some time, and it's on the way back. But not with Mazda.

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 ...

GE Aerospace lifted the curtain on its comprehensive hypersonics program at its Research Center in Niskayuna, demonstrating what is believed to be a world-first hypersonic dual-mode ramjet (DMRJ) rig ...

It takes a lot of fuel to launch something into space. Sending NASA’s Space Shuttle into orbit required more than 3.5 million pounds of fuel, which is about 15 times heavier than a blue whale. But a ...

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 ...
