What is the source of these drawings?
Layout #1 in particular seems VERY lossy. The Germans were very conscious of duct losses and tried to keep intake and nozzle lengths down to a minimum (see Me-262, He-162, p.1011, etc.). These look rather long and 'twisty', hardly conducive to good efficiency.
I am also wondering where the wing spar is supposed to pass through, if the required space is taken up by ducting.
