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 ...

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 ...

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 ...

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 ...

The bright minds from the University of Central Florida (UCF) are on a path to revolutionize the future of air travel, and even facilitate interplanetary transportation. In the quest to find a ...

Essentially, it's a rotating detonation engine in which the detonation wave is stabilized within a high-speed rotor. A precisely shaped flow channel within the rotor compresses the air-fuel mixture to ...

Conceptual image of an oblique detonation wave engine-powered hypersonic aircraft. (Courtesy: background image: NASA; composite image: Daniel A Rosato) Scientists in the US have produced a detonation ...

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 ...
