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.

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 ...

Russia has demonstrated a pulse-detonation engine (PDE) with low-energy ignition and a specific impulse of 800s in static conditions, about half that of comparable hydrocarbon-fuelled ramjet at Mach 2 ...

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 ...

At a laboratory near Seattle and a test site in the California desert, Pratt & Whitney is exploring a new form of propulsion that could make the turbojet engine better — or make it obsolete. Within 10 ...

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 ...

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 ...
