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 ...

A US-based propulsion company has successfully launched and flown a new rocket powered by a unique rotating detonation engine. Although relatively small by rocket standards, the test could pave the ...

Detonation is a supersonic combustion wave, characterized by a shock wave driven by the energy release from closely coupled chemical reactions. It is a typical form of pressure gain combustion, ...

A new family of engines aims to harness the power of detonation shockwaves to create ever-faster rocket engines. One of these engines—known as a rotating detonation engine (RDE)—has shown some ...

There probably never was a better time for rocket engine fans to be alive. It's a time when those who have the means can go out and start building the rocket engine of their dreams, while the rest can ...

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 ...

ISTR that the SR-71 was about a foot longer at speed than at rest. They definitely leaked fuel on the ground. And I don't have the unclassified POH for it handy, but ISTR that the SR-71 did the 'dipsy ...
