Remember the proud press releases from some of the first all digital products(777, F35, etc) were assembled - and how they fit so well? It implies that was unusual in the past.
|Quoting VC10er (Thread starter):|
or is there an acceptable variance for every manufactured airplane?
|Quoting UAL747 (Reply 8):|
A 747's wingspan varies, as do most large span aircraft, depending on how much fuel it is carrying. I believe the wingspan increases about a foot with heavier fuel loads.
|Quoting kanban (Reply 10):|
I would question that only because the upper and lower skins plus the front and rear spars can not grow and shrink.. they are one piece .. now if they "grow" because the curvature changes , that's another story
|Quoting tdscanuck (Reply 11):|
Dihedral...as you increase fuel load the wing flexes down and, since it was slightly bent up to start with, the span gets larger.
|Quoting nighthawk (Reply 3):|
It sure was the case in the past, as the UK discovered when it tried to re-wing the Nimrod. They took a sample Nimrod and took the measurements needed for the wings. The wings were produced using modern techniques, and therefore had variances of just a few mm. When they came to fit those wings to the fuselages, they discovered no two fuselages were the same, and none of the wings would fit! This was due to much greater variances in the fuselage, as it was hand built.

Wasn't the April 1st edition was it?
