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 ...

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 ...

GE and Lockheed Martin have demonstrated a new rotating detonation engine ramjet design in a series of tests that show significant potential for efficiency gains. If developed into a full missile ...

Breakthroughs, discoveries, and DIY tips sent six days a week. Terms of Service and Privacy Policy. In a video live-streamed April 7, the Air Force Research ...

DARPA has contracted Raytheon to develop a practical version of a revolutionary air-breathing rotating detonation engine called Gambit, which would have no moving parts and could lead to lighter ...

Researchers in Purdue University’s College of Engineering are testing a patented Tesla valve-inspired injection manifold design that could improve the performance of rotating detonation engines. RDEs ...

As our civilization is gearing up to take big bold steps in the immediate neighborhood of our planet (read the Moon and Mars), rocket scientists have begun looking at ways that could enable more ...

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 ...

I assume that if the detonation/flame front is itself rotating within the combustion chamber/channel/however one chooses to contain and direct it, then the expanding shockwave from the exhaust plume ...

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 ...

Over the years [Integza] has blown up or melted many types of jet engine, including the humble pulsejet. Earlier improvements revolved around pumping in more fuel, or forced air intakes, but now it’s ...

Researchers at Purdue University's College of Engineering are conducting tests on a patented Tesla valve-inspired injection manifold design to improve the efficiency of rotating detonation engines ...
