As Mike has noted, a compound curve is quite strong. The geodesic is an amalgam of strong linear shapes, the triangle being the most elegant. There are two considerations in three dimensions, compression and tension. A cylinder (fuselage) has terrible compressive strength, marginally better tension. The strongest three dimensional fuselage (section) would be the triangle, basically three trusses fastened on edges. This shape would be strong in bearing, tension, and in torsion (twisting). To gain volume (but lose strength) the "Tube" is born.
The modern aircraft is robust, and impossibly weak, depending on the stresses, and weight.
I am no engineer, so you know, my background has been in design and fabrication. I still am unsure what you want to accomplish with Fullerine dogma v/v a/c. ??
