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 ...

Rotating detonation engine could be up to 25% more efficient than traditional jet engines. This could make airplanes and missile faster or with longer range. Smaller weapons could reach the same ...

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 ...

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 ...

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 ...

February 2, 2006 UK-based RCV Engines is best known globally for its range of model aircraft engines but the unveiling yesterday of a prototype 125cc Rotating Cylinder Valve (RCV) scooter engine could ...

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 ...
