No offence meant Lyman, but you tend to talk (type) in riddles.

So in the interest of discussion, until more data is released by the principals, (I won't hold my bleed air), how do you interpret the turboshaft concept + CFRP?
Sorry, no idea what you are getting at here. It is what it is. The engines are no different really from their predecessors. Two gennies instead of one and no bleed air apart from engine anti-ice.
CFRP is another story. Not new, but the way that Boeing have used it is. How it withstands ramp-rash was one of the major worries. The idea that the aircraft would be grounded due to overheating batteries was certainly not on my list of gotchas when I did the course. The fuselage being thumped by a highloader and the consequent inspection required afterwards was my No.1.
As for the RAT. Well to be honest they get more use in the hangars don't they? No innovation required there except, as I said before, to keep the weight down.
