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 (RDEs), as opposed to oblique wave detonation engines or pulse detonation engines, use ring-shaped chambers and precisely-timed fuel injection to generate constant thrust.

Engineers have developed a new kind of engine that could make rockets much easier to build – but it’s very unstable. In more than half a century since humans first walked on the moon, little has ...

It takes a lot of fuel to launch something into space. Sending NASA's Space Shuttle into orbit required more than 3.5 million pounds of fuel, which is about 15 times heavier than a blue whale. But a ...

WASHINGTON--With its strong dependence on gas-turbine engines for propulsion, the U.S. Navy is always looking for ways to improve the fuel consumption of these engines. At the Naval Research ...
