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.

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 ...

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 ...

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 ...

General Electric has begun running a pulse detonation engine (PDE) in its experimental Global Research Center laboratories in Niskayuna, New York. It plans to fire up a full-scale demonstrator as ...

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 ...

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 ...

Power generation and distribution is a big problem in Nigeria and a Nigerian in the US is willing to save all of us from this national embrassment. Abdulraheem Bello is the young small man with a ...

Last year, the Defense Advanced Research Projects Agency (DARPA) quietly unveiled a new high-speed missile program called Gambit. The program is meant to leverage a novel method of propulsion that ...

Detonation is a supersonic combustion wave, characterized by a shock wave driven by the energy release from closely coupled chemical reactions. It is a typical form of pressure gain combustion, ...
