Continuing high fuel costs and growing environmental pressures could inject new urgency into development of pulse-detonation engine (PDE) technology for wider commercial applications, rather than just ...

Tests of an advanced pulse detonation engine (PDE) design are coming closer than ever to proving the viability of the concept. Potential applications range from supersonic unmanned combat air vehicles ...

Various forms of unsteady or pulse detonation combustion in the future could feature turbine-based combined cycle (TBCC) engine concepts that form part of NASA’s ongoing studies into highly reliable, ...

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 ...

With oil priced at about $120 a barrel and ever-growing pressure to reduce aircraft emissions, the search for leaps in engine efficiency is renewing interest in novel approaches, such as wave rotor ...
