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 Florida team working with the US Air Force claims that it's built and tested an experimental model of a rotating detonation rocket engine, which uses spinning explosions inside a ring channel to ...

The Rotating Detonation Engine being developed by Pratt & Whitney has no moving parts, which reduces complexity and costs, and could help enable high-speed, long-range flight with increased efficiency ...

A new rotating detonation engine could revolutionize rocket launches—if it can be made stable enough. That’s a big “if,” and one that researchers are hoping to explore using a new mathematical model ...

The Defense Advanced Research Projects Agency (DARPA) has joined forces with Raytheon to advance the development of a groundbreaking air-breathing rotating detonation engine called Gambit. Unlike ...

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 ...

Venus Aerospace, making hypersonic flight a reality for commercial and defense purposes, has achieved the first long-duration engine test of their Rotating Detonation Rocket Engine (RDRE) in ...

Counter-rotating wind turbines (CRWTs) represent an innovative paradigm in wind energy conversion, employing a dual rotor mechanism in which two coaxial rotors spin in opposite directions. This ...

There have been published papers by the Air Force Research Lab and NASA on rotating detonation engines having 10% or more efficiency gains. A rotating detonation engine (RDE) uses a form of pressure ...
