An international team of engineers that includes combustion experts from the University of Sydney's School of Aerospace, Mechanical and Mechatronic Engineering are working on a revolutionary new ...

The main problem holding back reusable hypersonic planes is that traditional ramjet engines become very inefficient over mach 2 while hypersonic engines do not work well below mach 4. There is the ...

They're noisy, but your next missile or military vehicle might have an RDE (rotating detonation engine) powerplant in it. RDEs are more fuel-efficient, lighter, easier to maintain, and capable of ...

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 ...

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 ...

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 ...

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 ...

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 ...

NASA fired a 4,000-lb.-thrust RDRE a dozen times in 2022. Credit: NASA NASA has successfully tested a 4,000-lb.-thrust rotating detonation rocket engine (RDRE) and revealed plans to develop 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 ...

Advancements in automobile engine technology have continued to rise exponentially, specifically in the past decade, where efforts have been focused on alternative engine technology. The passenger ...
