I would like to learn more about the "bending beam" type of wing structural design in which the wing halves are attached to fuselage via pivots which support the fuselage and resist torsion but the bending moments are resisted by one or more carry-through stuctures.

I would love to see some real world examples and would welcome any relevant design advice, whether off the cuff or by pointing me to specific design resources. Some questions I have are...

--Overall, what are the pros and cons of this approach vs. a rigid box carry-through or strut-braced wing?

--If the wing is built in two halves, what are the pros and cons of integrating the carry through in each wing half vs. a third, separate component?

--If the carry-through is integral to each wing half, what are the pros and cons to using left and right carry-through structures joined at the centerline vs. staggered, overlapping carry-through structures, each of which continues all the way to the other side of the fuselage?

Cheers,

Matthew
