Yesterday, Vladimir Putin presented his country with a belated Christmas present: the Avangard hypersonic missile. According to Russian media, it's capable of reaching Mach 20. And if its ability to ...

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 ...

Detonation is a supersonic combustion wave, characterized by a shock wave driven by the energy release from closely coupled ...

Pulse detonation engines (PDE) can achieve a maximum of 50% efficiency verus 30% for conventional jet engines Pratt & Whitney and General Electric now have active PDE research programs in an attempt ...

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 ...

A pulse detonation engine, or “PDE”, is a type of propulsion system that uses detonation waves to combust the fuel and oxidizer mixture. The engine is pulsed because the mixture must be renewed in the ...

Since the detonation tendency of the fuel is the limiting factor in the development of power and the efficiency with which the fuel can be burned, the author considers this phase of the subject .with ...

The demon of engine knock is something an owner of a traditional high-performance Pontiac knows all too well. An engine designed when 102-octane high test was at almost every fuel station in the ...

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 ...

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 ...
