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 ...

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 ...

When is an empty tube not an empty tube? When it's a ramjet that uses rotating detonation technology to propel aircraft at hypersonic speeds. A case in point is Venus Aerospace's new Venus Detonation ...

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 ...

Yesterday, Vladimir Putin presented his country with a belated Christmas present: the Avangard hypersonic missile. According to Russian media, it's capable of reaching Mach 20. And if its ability to ...

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 team of researchers in Florida, working with the United States Air Force, claim to have built and tested an experimental model of a rotating detonation rocket engine. This type of engine uses ...

Venus Aerospace, making hypersonic flight a reality for commercial and defense purposes, has achieved the first long-duration engine test of their Rotating Detonation Rocket Engine (RDRE) in ...

Engineers have developed a new kind of engine that could make rockets much easier to build – but it’s very unstable. In more than half a century since humans first walked on the moon, little has ...

Breakthroughs, discoveries, and DIY tips sent every weekday. Terms of Service and Privacy Policy. In a video live-streamed April 7, the Air Force Research laboratory ...

From a thermodynamic point of view, detonations are more efficient than the more commonly known deflagration (classic combustion). While classic combustion in rocket engines takes place at constant ...
