How thick are the sidewalls of Tristar, and how wide is the cabin?
The outside fuselage width is well known. 597 cm. DC-10 is 5 cm wider, at 602 cm.
However, it is said that the Tristar walls are thinner at sides. The frames are thinner, skin is thicker and there are no stringers. It is said that although Tristar is 5 cm narrower than DC-10 outside, the cabin is wider due to thinner sidewalls.
Il-96 is 608 cm outside, and B-777 is 620 cm outside. How do their sidewall thicknesses and cabin widths compare to Tristar and DC-10?
How wide is A350? I have heard different numbers, like 591 cm and 596 cm. Which is right, and how does the cabin compare against Tristar and DC-10?

Chornedsnorkack, why do you create a thread asking questions and then ostensibly proceed to answer those questions yourself? Surely you could just kind of answer them without creating the thread? :confused:

No, I could not. I could find the cross-section of DC-10, but not that of Tristar. This is why asked the question.
Now that I got the Tristar cross-section, I was able to use it to find the numbers and spell out the result. I still did not get the cross-sections of Ilyushin and A350, so those questions are still pending.

Here is an example of L-1011 seating:
Thanks, this was useful!
Counting the width of seats and aisles on the 10 abreast seating just like on the 10 abreast DC-10, you will reach interior width 226 inches, not 223 inches. This is 2 inches wider than the DC-10 – in fact, seat widths are exactly equal, the difference is that DC-10 has 16,5 inch aisles and Tristar 17,5 inches. The two sidewalls of Tristar take up 9 inches, while DC-10 has 13 inches between the two sidewalls.
Now, what are still missing are the cross-sections of Ilyushins and A350. Ilyushins, at 608 cm, are 6 cm wider than DC-10. A350… how much is it narrower than Tristar?

Here is an example of L-1011 seating:

The L-1011’s fuselage exterior diameter (in the constant section) is 235 inches and the interior diameter was 223 inches. The L-1011 interior was wider that the DC-10 because the L-1011 used tapered frames and a stringerless sidewall
Look at DC-10

page 20.
10 seats, 2 aisles and their armrests combined have 224 inches width.
Lockheed website is unfortunately not so detailed.

It would seem not, Matt. :confused:
