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 ...

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’s State-owned Rostec group has announced that its subsidiary, United Engine Corporation (UEC), had completed the first round of tests on a pulse-detonation technology demonstrator engine. The ...

The developer of a Russian pulse detonation engine demonstrator claims that initial tests show an improvement in specific thrust compared to conventional engines. Rostec announced on 9 April that the ...

Flight tests of an experimental aircraft powered by a pulse-detonation engine are to be retried by the end of this year, says the Ohio-based US Air Force Research Laboratory (AFRL). The engine has ...

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 ...

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 ...

Bellevue developers of a new type of jet engine are finding the real money may lie in using the engine's "pulse detonation" technology to clean dirty power-generation furnaces. The new market is so ...

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 ...
