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?

Should be the rotating detonation engine.

Real engineering also did one (actually better than Scott's I think)
