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 ...

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 ...

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 ...

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 ...

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 ...

Disk rotating detonation engines could provide engines that are 10% more efficient, which could enable hypersonic planes. The USA, China, and Russia will be ramping up hypersonic weapon and hypersonic ...

The race to field reusable hypersonic aircraft got a whole lot hotter last month, with GE Aerospace announcing a breakthrough in high-speed jet engine design that could potentially allow conventional ...

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 ...

Engineers at the University of Washington are working on a new type of rocket engine that holds the promise of being lighter, more efficient, and simpler to make than conventional liquid-fuel rockets.
