Firefly Posted May 1, 2008 Share Posted May 1, 2008 Just want to check on the positioning of the Upper Longerons -- Since the sides are formed with curves in 2 planes, and the upper longeron only has a bend in it (and no "twist"), my guess is that the UL will lay flush at the front (that is be perpendicular to the side) and by the aft end should be at an angle less than 90 degrees to the sides due to the induced twist created by FJD and FJE. Or stated otherwise, I'm NOT expected to try and "twist" the UL. Is this correct? I found the plans drawing a bit lacking in this area. But my assumption is that the spacers ensure that the UL's DON'T get twisted in this step. I just wanted some confirmation (...or correction).

Jon Matcho Posted May 1, 2008 Share Posted May 1, 2008 If I understand correctly... there shouldn't be any twist in the ULs (don't get distracted with the plane of the sides), just a bend. Clamping and the spacers should result in the ULs being straight and flat. See here.

Big Steve Posted May 1, 2008 Share Posted May 1, 2008 Yep no twist should be flat. The ends will not be exactly perpendicular do to them comming off of a slight radius.
