GE Aerospace and Lockheed Martin completed a series of engine tests demonstrating the viability of a liquid-fueled rotating detonation ramjet for use in hypersonic missiles, the first initiative ...

The rotary engine has been absent on the frontline for quite some time, and it's on the way back. But not with Mazda.

Rotating detonation engines In 2020, we saw the first of an "impossible" new breed of rotating detonation engines (RDEs) fire up on a test bench. These machines leave the slow, controllable world of ...

Engine maker GE Aerospace and defence manufacturer Lockheed Martin have teamed up to test a novel ramjet propulsion system for powering hypersonic flight. The pair say they completed a series of ...

GE Aerospace and Lockheed Martin complete missile-scale rotating detonation ramjet tests, targeting longer-range and more efficient hypersonic weapons.

For years, the United States has trailed behind Russia and China in hypersonic weapons. A new engine prototype by Lockheed ...

As the industry’s transition to electrified vehicles continues, albeit at a slower pace, you wouldn’t think many would be working on developing more sophisticated internal-combustion engines. Oh, to ...

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 ...

Astron aerospace has shown a partial prototype of a new rotary combustion engine it claims runs at an extraordinary 60% thermal efficiency, burning totally clean with zero NOx emissions and nothing ...

A US-based propulsion company has successfully launched and flown a new rocket powered by a unique rotating detonation engine. Although relatively small by rocket standards, the test could pave the ...

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 ...

An engine capable of transforming a shock wave into stable propulsion: this is the idea behind a recent technological breakthrough. In China, a team of researchers has developed a system that could ...
