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 ...

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 ...

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 ...

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.

An experimental pulse-detonation-powered aircraft should begin test flights next month at Mojave, Calif., now that the FAA has issued it an airworthiness certificate. Powered by a pulse detonation ...

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 ...

An international team of engineers that includes combustion experts from the University of Sydney's School of Aerospace, Mechanical and Mechatronic Engineering are working on a revolutionary new ...

Over the years [Integza] has blown up or melted many types of jet engine, including the humble pulsejet. Earlier improvements revolved around pumping in more fuel, or forced air intakes, but now it’s ...

A US-based propulsion company, Venus Aerospace, said Wednesday it had completed a short flight test of its rotating detonation rocket engine at Spaceport America in New Mexico. The company’s chief ...

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 ...
