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 ...

Russian powerplant specialist United Engine has carried out initial testing of a pulse-detonation rocket motor which has potential application to orbital spaceplanes or hypersonic aircraft.

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 US Air Force Research Laboratory (AFRL) and Scaled Composites plan to conduct around late September what is described as the first-ever flight of a pulse detonation engine (PDE)-powered aircraft.

An international team of engineers that includes combustion experts from the University of Sydney's School of Aerospace, Mechanical and Mechatronic Engineering are working on a revolutionary new ...

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, ...

A new kind of engine under development, called a detonation engine, could save the military hundreds of millions of dollars in fuel costs every year. The technology, which military researchers are ...
