Engineers at the University of Washington are working on a new type of rocket engine that holds the promise of being lighter, more efficient, and simpler to make than conventional liquid-fuel rockets.

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 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 ...

A new rotating detonation engine could revolutionize rocket launches—if it can be made stable enough. That’s a big “if,” and one that researchers are hoping to explore using a new mathematical model ...

A Florida team working with the US Air Force claims that it's built and tested an experimental model of a rotating detonation rocket engine, which uses spinning explosions inside a ring channel to ...

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 ...

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 ...

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 ...

Air enters the RDE inlet and as it passes the isolator, it mixes with fuel injected in a sequential, circular manner and ignited at the detonation annulus. The notional detonation wave front is ...

Texas-based startup Venus Aerospace clears a major hurdle in its new reusable hypersonic engine technology. When you purchase through links on our site, we may earn an affiliate commission. Here’s how ...
