Hi,
For a 3D project I am working on I have been looking at the construction of the Boeing 747(200) and specifically the distribution of windows along the fuselage and I am hoping someone here can help with something that is confusing me...
I have downloaded as many schematics, cad drawings and reference images as I can find on Google and it all pointed to the idea that the fuselage was made of a series of rings connected together each having either a window / no window / or forming part of a door section. This would then lead all windows to be uniformly spaced along the side.
However whilst I found this to be true for pretty much all windows there's a section between Door 3 and Door 4 where the window spacing increases by approximately 1/4 of the window width for the end 4 windows and I can't understand why this is?
Illustration:
< Fore [D3] [ ]----[ ]---[ ]--[ ]-[ ]-[ ]-[ ]-[ ]-[ ]-[ ] [D4] Aft >
Can anyone say why the windows aren't spaced evenly in this short section? Are the 'rings' that form the fuselage also unevenly sized in this section?
I hope this makes sense and someone can help!
