Re: Boeing NMA in doubt as customers push for all new 737MAX and 757 replacement

Yes stress would focus - but that is the strongest part of the cross section. At the part of the Aircraft where stresses are the most you would also have the Wingbox helping. I'm not sure It would be that material, and it would be shorter as well potentially lowering the wetted surface area differe...

Re: Boeing NMA in doubt as customers push for all new 737MAX and 757 replacement

Or half a circle on top and 1/3 of a larger one on the bottom joined at the floor beam so it's in tension vs compression. How would this work, at the floor beam there would be an abrupt change in curvature where stress would focus. This would transfer normal stress into a lot of shear stress at the...
