Then crash course in german engineering 101:
When you discuss an idea, it is not the person under criticism, it is the idea.
If you get a tip about an limitation you have to change it, or set an IF.
e.g.: IF the neutral point stays within the limits whilst using pitch.
Too many IFs are pushing the project from hard to manage to science fiction.
As I already said, it is mainly the distance between the fixpoints of the wings that gets this project to Science fiction. With this layout the project gets the following IFs:
IF the structural analysis is sober with consideration of turbulences,
IF the neutral point of lift stays within the limits,
IF the aeroelastic layout is done properly or new meterials appear,
IF someone needs an newly designed aircraft with the capacy of 2 A380s,
IF the airports get to manage the newly type of aircraft,
the plane could be built.
As you may have seen, even the Cranfield study has not this much space between the wings, you should think a bit of it. I mentioned already that aeroelastics may be a lot of a problem, this layout might work in a wingspan from 20-30 meters, 80 meters is sheer to much bravery.
