GE Aerospace says it successfully demonstrated an advanced jet propulsion concept that involves a dual-mode ramjet design utilizing rotating detonation combustion. This could offer a pathway to 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 ...

The world of hypersonics is perhaps just as captivating to some people as say space exploration is to others. After all, it's all about going really, really fast through Earth's atmosphere, many times ...

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 ...

The race to field reusable hypersonic aircraft got a whole lot hotter last month, with GE Aerospace announcing a breakthrough in high-speed jet engine design that could potentially allow conventional ...
