Bear with me Dude, I think your drawing in post #12 has done it for me, but I'm prepared to be embarrassed yet again.
Its a
bypass? 
The "power" is generated by the action of shock waves slowing the air mass and passes
around the 593 to mix with the core engine exhaust within the buckets? So, it is the opposite of a High Bypass fan, in that a core of 'relatively low' velocity air from the 593, is surrounded by a tube of very high velocity/energy air from the intake?
I refer to the 593, buckets and intake as
components, because the whole assembly is 'The Engine'. Is that how you see it? Please say I've got it, because its been doing my head in since the statistic (75% thrust from intake) was first mentioned.
ROger.
