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 ...

If we are to truly become a solar system-wide civilization, we really need to rethink the means of propulsion that are currently taking us off our own planet. After all, current rocket engines are ...

Pulse detonation engines (PDE) can achieve a maximum of 50% efficiency verus 30% for conventional jet engines Pratt & Whitney and General Electric now have active PDE research programs in an attempt ...

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 ...

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 ...

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 ...

The rotating detonation rocket engine (RDRE) is the new Holy Grail of the aerospace industry. The way such a technology works promises unprecedented speeds for aircraft and spacecraft, prompting ...

Russian powerplant specialist United Engine has carried out initial testing of a pulse-detonation rocket motor which has potential application to orbital spaceplanes or hypersonic aircraft.

Like much in life, the difference between detonation and pre-ignition, and their effects, comes down to timing. Both refer to a situation when an engine's fuel/air mixture combusts at the wrong time, ...
