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 ...

Venus Aerospace conducted its first powered flight last month, reaching Mach 0.9 with a drone. The 8-foot-long vehicle was dropped from an Aero L-29 Delfín aircraft at 12,000 feet and flew under the ...

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 ...

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 ...

An innovative new combustion engine eliminates half the guts of a traditional engine, and uses a fascinating internally rotating piston and sleeve arrangement, making it lighter, simpler and more ...
