With around 430 gas-turbine engines on 129 of its ships burning about US$2 billion worth of fuel every year, the U.S. Navy is examining the potential of using Rotating Detonation Engines (RDEs) to ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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.

Pratt & Whitney has secured a US Air Force (USAF) contract to develop a ground test demonstration of a rotating engine detonation concept. Joining Pratt on the project will be sister companies under ...
