I don't think they're modeled after any engine, really. Except for the VTOL Nozzles, they're modeled after the Harrier's TVC.
I'm not that sure about the High-Bypass turbofans, but the afterburning turbofan certainly doesn't look like any afterburning turbofan I know. So are the other engines.
@ZeroWithSlashedO Thanks for the help! Kind of disappointing, but it is what it is.
