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 ...

Russia’s State-owned Rostec group has announced that its subsidiary, United Engine Corporation (UEC), had completed the first round of tests on a pulse-detonation technology demonstrator engine ...

Rostec claimed its pulse detonation engine has a more efficient thermodynamic cycle than currently operated gas turbine engines. It added that initial tests of the demonstrator powerplant showed an ...

As the detonation wave travels down the tube at supersonic speed, it reduces inlet pressure and draws in fresh air and fuel, generating thrust. Each pulse lasts milliseconds.

Categories include pulse detonation engines, rotating detonation engines and standing wave, or oblique wave detonation engines (OWDEs), and while these are still all at experimental stages, they ...

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 ...

The Russian Advanced Research Foundation has announced the construction and testing of a pulse-detonation rocket engine, which uses high thermodynamic efficiency to allow spacecraft to achieve ...

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 ...

Chinese scientists have been leading the way in developing the technology that could transform hypersonic military ...

With around 430 gas-turbine engines on 129 of its ships burning about US$2 billion worth of fuel every year, the U.S. Navy is examining the potential of using Rotating Detonation Engines (RDEs) to ...
