Some of you may be designing aluminum riveted sheet metal airplanes that have graceful fuses and tapered wings. Thus the need for non-perpendicular flanges. Perhaps such projects are more suited to composites but let's assume we do it Aluminum stressed skin structure like Hummelbirds.
With appropriate thickness for given load I don't have any reasoning to believe that non perpendicular flanges are weaker than perpendicular ones but still I can't figure out why perpendicular flanges look more robust.
Are there any Hummel builders out there? Does a Hummel have any issues with flanges other than those related to forming? I see Hummelbirds have lots of circular fuse sections.
I don't know.. but boxlike sonexes sure look robust.
