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 ...

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 ...

Rotating Detonation Engines (RDE) have been flown by Venus Aerospace. They use continuous detonation waves for propulsion and provide 15% efficiency gains (in specific impulse or fuel consumption) ...

WEST LAFAYETTE, Ind. – Researchers at Purdue University have developed new combustion technology that can shrink the size of engines and eliminates the need for them to be round in shape. The novel ...

There was a time when Stephen Hawking’s predictions were greeted with skepticism. (Not surprisingly, as it also happened to Newton). However, over the decades, they have been proven—almost all of them ...

Chinese scientists proposing a new concept for a hypersonic engine with improved continuous thrust, lower start-up speeds and enhanced performance have inserted a ramjet into a rotary detonation ...

Detonation is a supersonic combustion wave, characterized by a shock wave driven by the energy release from closely coupled chemical reactions. It is a typical form of pressure gain combustion, ...

A US-based propulsion company, Venus Aerospace, said Wednesday it had completed a short flight test of its rotating detonation rocket engine at Spaceport America in New Mexico. The company’s chief ...
