I am actually trying to understand which option is going to be a more relaible for the wing-fuselage attachment. Should I choose a connection between the flanges of the spars within the wing to the internal structure of the fuselage, or I should go with the attachment of webs of the spars within wing to the fuselage? What most of the aircrafts opt for, and does it depend on what aircraft category it belongs to (like commercial/fighter/cargo etc).
If any answers are provided, it would be appreciated to back it up with reasons.
(Does aircrafts also connect the wing skin to the fuselage skin? If yes, then what kind of aircrafts do that and why).
