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 ...

The fuel injection ignites a flame-like detonation wave that travels around the ring for as long as fuel is injected. The energy generated from it is converted to thrust that’s ...

A novel type of jet propulsion, a rotating detonation engine (RDE), has been successfully tested by Pratt & Whitney. The development is highly significant for the U.S. military, with RDE ...

One of these engines—known as a rotating detonation engine (RDE)—has shown some considerable promise, but still needs to overcome barriers or poor thrust continuity and high Mach operability ...

Pratt & Whitney is planning further development of rotating detonation engine (RDE) technology following “positive test results” from a series of ground tests. The work, which was completed ...

However, the Japan Aerospace Exploration Agency (JAXA) has recently completed a successful test of a different type of rocket, known as a rotating detonation engine. The engine relies on an ...

This is a journey towards a very interesting engine design, known as the rotating detonation engine. This will be very interesting to see, if he can get it to work. Supersonic exhaust plume with ...

Particularly promising is the so-called rotating detonation engine in which detonation waves propagate continuously around an annular combustion chamber at high frequency and thus generate ...

Pratt & Whitney will accelerate its work on rotating detonation engine (RDE) technology, as its programme to develop the advanced propulsion capability yields results. The company has completed a ...

EAST HARTFORD, Conn., March 4, 2025 /PRNewswire/ -- Pratt & Whitney, an RTX (NYSE: RTX) business, has completed a series of tests on its rotating detonation engine (RDE) work with the RTX ...

The engine architecture was unveiled in October at UP.Summit and combines the high thrust and efficiency of the Rotating Detonation Rocket Engine (RDRE) with the high-efficiency cruise of a Ramjet in ...
