It's a Rotating Detonation Rocket Engine"

What makes the RDRE so revolutionary is that it makes use of a sustained detonation circling around a ring-shaped channel, fed by a mix of fuel and oxygen which is ignited by each passing explosion.
Crucially, the RDRE uses less propellant fuel than conventional rocket engines, and is simpler in terms of its machinery and mechanisms. That means going into space becomes cheaper, and traveling further distances becomes possible.

NASA invented a space ship powered by a rotary engine? Noice, at least until the apex seals give out, but they should be good for 80k at least.

I see what they did there.

This is a fancy aerospike engine right? The rotating detinations gives it higher chamber pressure and therefore better ISP or something?

I will look for the Scott Manley video on this later (I think it was him?) Edit: also a Real Engineering one that explains the aero-spike nozzle

Anyone have the ISP of this experiment to compare to other engines?
