Fuselage design
Hi
Just wondering why the different aircraft manufacturers use such different designs of stringers in their fuselage structures, ie Airbus and Boeing. Airbus ones are more like an S shape while Boeing use a J shape one. Which is better? Is it something to do with their Second Moments of Area? Just curious as to which would be used on a slightly faster aircraft such as the Sonic Cruiser.
Also, what determines how far apart the frames are spaced along the fuselage in a typical commercial airline design. How would area ruling be incorporated?
Cheers
