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.

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 ...

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 ...

A jet engine with no moving parts. Sounds like something out of Dune. But a Baltimore start-up successfully flight-tested a scaled version to prove that the concept worked. Wave Engine Corp. released ...

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 ...

Rotating detonation engines (RDEs), as opposed to oblique wave detonation engines or pulse detonation engines, use ring-shaped chambers and precisely-timed fuel injection to generate constant thrust.

Every one of the modern US Navy’s 129 ships, and its entire fleet of aircraft, relies on gas turbines for either basic propulsion or to generate electricity for their critical systems—typically both.
