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 ...

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.

Engineers think that if they add pulse detonation technology to a low-bypass-ratio turbine engine—the modern fighter jet engine—they can get the efficiency benefit of pressurized, shockwave combustion ...

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 ...

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 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 ...

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 ...

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.

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 ...
