Russian powerplant specialist United Engine has carried out initial testing of a pulse-detonation rocket motor which has potential application to orbital spaceplanes or hypersonic 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 ...

Pulse detonation technology being pursued by General Electric, Pratt & Whitney and Rolls-Royce offers engine-makers the potential for improving gas turbine specific fuel consumption by double digits ...

A startup high-speed flight company from Houston, Texas, has successfully tested its Rotating Detonation Rocket Engine (RDRE) ultimately aimed at allowing travel at four to six times the speed of ...

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 ...

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.

General Electric is ramping up studies into how to make production-standard pulse-detonation en­gines as it prepares to run the first-ever valve-controlled multi-tube PDE with a power turbine and gear ...

Such an engine uses a series of controlled explosions that travel around a circular channel at its base. The result is a massive amount of thrust coming from a much smaller engine using significantly ...

The Rotating Detonation Engine being developed by Pratt & Whitney has no moving parts, which reduces complexity and costs, and could help enable high-speed, long-range flight with increased efficiency ...

Bello met us at Pulse and told us everything you need to know. Abdulraheem Bello is the young small man with a giant's mind. The brain behind a great startup, Afthon, established to in 2014 to solve ...
