World-first “impossible” rotating detonation engine fires up

A Florida team working with the US Air Force claims that it’s built and tested an experimental model of a rotating detonation rocket engine, which uses spinning explosions inside a ring channel to create super-efficient thrust.

Fans of aerospike engines take note.

I only have three brief comments to make.

• Pulsed combustion was a feature of the V1 buzz bomb ramjet engines, and has been used in some ramjet engines since.
• Pulsed combustion as a means of firing furnaces was studied by a colleague of mine at CSIRO.
• Noisy and somewhat irregular thrust. So better for space.

So the “impossible” description is pure BS?

probably why it is in quotes. plus the other pulse jets are jets, not rockets. and work on different principles.

Now had a quick look at the article.

Seems it’s more detonation vs combustion, rather than jet vs rocket, that makes it new and previously thought impossible.

How small could nuclear detonations be for a space engine ?

How far could it be scaled up to?

Very, very, very large.

Project Orion.

Thanks for that.
