Response to Hey Jeff. I am real bad at explaining things but I found this on youtube that might help.

I've watched quite a few videos of this guy, but not this one! I think they're some of the best videos out there as far as technical insight, good explanation and walkaround detail go, especially with my favourite, the J-79. Did you notice, towards the end of the video when he films the burner can, how green the inner liner is?
He says that the flame holder forms an area of low velocity - does that not seriously hamper the engine's performance in non-AB operation? I basically thought that the purpose of the flame holder was to prevent the AB flame to cause any damage to the turbine, i.e. create a cool cushion between the turbine and the flame area. But what you've said about not blowing the flame out makes sense as well. Still not entirely sure why it's designed this way but I'm sure they would have designed it differently if there was any better way.
