If you look at aircraft from the Second World War or earlier, you'll notice that many of them have engines with large frontal areas and cylinders arranged about the propeller crankshaft. This a radial ...

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 ...

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 ...

The 20th century was the age of the internal combustion engine. The fruits of industrial progress produced power plants tasked with everything from running generators to powering warplanes. The First ...

Engines that convert chemical energy from fuel into kinetic energy via explosive detonation, rather than slower deflagration combustion as seen in typical internal combustion engines. Categories ...

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, ...

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 ...

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 ...

Detonation is a dirty word around hot rods. Nobody likes to talk about it because when it happens, it usually means some lapse of attention during engine or vehicle assembly has occurred. By the time ...

War is hell kids, but it's undeniable that many world-changing technological advances were derived from armed conflict. War-related research brought us the moon landing, jet powered airliners, ...
