oooOOOooo! another tube with wings, how nice.
There is only so much you can squeeze out of this layout. I'm eager to see BWB and canards have their turn. Designers (dictated to by bean counters) are using material advances to save weight on a design that still actively produces negative lift, when they could be using composites to explore none-circular pressurised fuselages. This would enable the fuz to do some useful aerodynamic work, along with canards iso H/tailplane and the potential docile nature of canards in stall/turb etc, the advantages outweigh the many hurdles involved, IMHO.
I do like the new generations of airliners though. Aerodynamic function dictates some beautiful lines; that 7E7 wing is a work of art.
