Meet the Birotary, a crazy new and complicated engine that has three cylinders arranged like a star, a rotating block, a ...

Disk rotating detonation engines could provide engines that are 10% more efficient, which could enable hypersonic planes. The USA, China, and Russia will be ramping up hypersonic weapon and hypersonic ...

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 ...

First developed in the 1950s at the University of Michigan, these rocket engines use powerful and chaotic detonations, self-propagating thanks to hypersonic shockwaves travelling around a ring-shaped ...

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 ...

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 ...

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 ...

At the U.S. Naval Research Laboratory, scientists are studying the complex physics of rotating detonation engines which offer the potential for high dollar savings by way of reduced fuel consumption ...
