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 ...

Researchers hope the first flight of an aircraft powered by a pulse detonation engine (PDE) will accelerate development of a propulsion concept that promises greater simplicity, lighter weight and a ...

Pulse detonation engines may be a long way off, but hold the promise of greater efficiency as well as power During a brief period just over a decade ago, sleeping citizens of Los Angeles were woken on ...

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, ...
