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 ...

The ramjet needs to be moving at high speeds in order for the compression wave to build up and start the engine cycle. That means it has to be accelerated by means of a booster rocket or dropping it ...

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 ...

When is an empty tube not an empty tube? When it's a ramjet that uses rotating detonation technology to propel aircraft at hypersonic speeds. A case in point is Venus Aerospace's new Venus Detonation ...

NASA has contracted Momentus to use its Vigoride orbital service vehicle as a testbed to demonstrate a rotating detonation rocket engine in space in 2026. The rotating detonation rocket engine is ...

Editor’s Note: This week, John Persinos interviewed Matt Eales, managing director of EAL Engine Services, a UK-based aviation ...

The EU’s Clean Aviation body has provided more detail on the two new narrowbody engine concepts it plans to fund in its second phase, readying them for service entry around 2035. In December, Clean ...
