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 ...

In what may be a world first, Venus Aerospace has, for the first time in the US, successfully flown a Rotating Detonation Rocket Engine (RDRE) that uses supersonic explosions to create thrust. Such ...

The Japan Aerospace Exploration Agency (JAXA) has announced that it has successfully demonstrated the operation of a rocket engine technology for the first time in space. This experiment proved the ...

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 ...

Liquid-fuelled rocket engine design has largely followed a simple template since the development of the German V-2 rocket in the middle of World War 2. Propellant and oxidizer are mixed in a ...

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 ...

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 ...

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 ...

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 ...

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 ...
