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.

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.

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 ...

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 ...

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 ...

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 ...

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.
