Researchers in China have introduced a new hypersonic engine concept by integrating a ramjet with a rotary detonation engine. A team at Tsinghua University in Beijing created a new design known as the ...

For years, the United States has trailed behind Russia and China in hypersonic weapons. A new engine prototype by Lockheed ...

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 ...

Engine knocking, or detonation, occurs when fuel in the cylinders ignites unevenly, causing metallic pinging sounds, reduced power, and potential engine damage. Key causes include low-octane fuel, ...

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 ...

Chinese scientists have once again innovated a new technology—and not just any technology, but an extraordinary new engine that could improve rotating detonation engines. It could have profound ...

Engine maker GE Aerospace and defence manufacturer Lockheed Martin have teamed up to test a novel ramjet propulsion system for powering hypersonic flight. The pair say they completed a series of ...

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 ...
