I’m willing to accept that a gold bullion transporter can look closer to a flying wing, but with any reasonable cargo density you are back to the standard design.
Trying to intuitively explain CFD results is apparently just as hard as dispelling the Bernoulli nonsense about airfoils.
I’m right and high aspect ratio wings are a harder materials science and design challenge than blended wings. There is a reason 10000x as much engineering effort is going into folding carbon fiber wings for passengers/cargo. The folding is to increase fuel economy through aspect ratio and fit in terminal box.
Everything I have said is trivial to prove with CFD and experimentally. I get that popular science articles need to entertain the masses.
Let me ask you this, why is the tail of passenger aircraft upward sloping?
