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 ...

A US-based propulsion company has successfully launched and flown a new rocket powered by a unique rotating detonation engine. Although relatively small by rocket standards, the test could pave the ...

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 with the ...

On May 14, 2025 Venus Aerospace became the first in the world to successfully fly a high-thrust rotating detonation rocket engine (RDRE) — achieving what no government or private entity had done ...

Essentially, it's a rotating detonation engine in which the detonation wave is stabilized within a high-speed rotor. A precisely shaped flow channel within the rotor compresses the air-fuel mixture to ...

Using a design once deemed too unstable to harness, NASA successfully tested a 3D-printed rotating detonation engine in 2023, marking a major breakthrough in propulsion. By exploiting supersonic ...

GE and Lockheed Martin plan to get around this by accelerating the missile using a rotating detonation engine, which uses a supersonic wave of detonating fuel that runs about inside an open-ended ...

The U.S. Naval Research Laboratory (NRL) is researching the possibility of using Rotating Detonation Engines (RDEs) to reduce fuel consumption in gas-turbine engines, says Kazhikathra Kailasanath, who ...

There probably never was a better time for rocket engine fans to be alive. It's a time when those who have the means can go out and start building the rocket engine of their dreams, while the rest can ...

Rotating Detonation Engines (RDE) have been flown by Venus Aerospace. They use continuous detonation waves for propulsion and provide 15% efficiency gains (in specific impulse or fuel consumption) ...

Engine maker GE Aerospace and defence manufacturer Lockheed Martin have teamed up to test a novel ramjet propulsion system for powering hypersonic flight. The pair say they completed a series of ...
