Split Wings
 

I know this is a stupid question but how are "split wings" held together. I know ther are tubes that slide into the fuselage but how are the secured so they don't fall off.I have never seen this up close in any of the construction pictures I have looked at and would like to try it on my next project.
Thanks

There is a hole through the fuselage and inside the wings for a hollow wing tube. The tube slides into a wing panel, through the fuselage, and into the other. The wing panels are then kept from sliding off the tube by a bolt inside the fuselage into the wing.

Its only stupid if you don't ask it!

On my EIII I had an arrangement where a brass wing tube slipped into a slightly larger brass tube in the fuse and then was held in place by a clip. It was kind of a hassle. And then I realized that there were actually 16 rigging wires holdlng the wing firmly in place! :D

You can use a screw that goes through both inner and outer tubes to keep them in place. With some smaller aircraft, especially gliders, you can simply use friction. There''s not a lot of spanwise load on a mode, so anything that can keep the wings from sliding out will work. I''ve had gliders that used a rubber band between two hooks that held the wings in place...the hooks were in the root ribs of the wings, and the rubber band stretched across the fuselage between the hooks.

Many ways to do the job.

Hi,

Can anyone send link for image of the split wing?

With best regards,

I've used two methods on my pattern planes. One, as above, uses hooks in the root rib that fit into the fuse sides. I use O-rings between the hooks. On the other plane, I screwed 1/4x20 nylon bolts through the root ribs from the inside. The bolts then go through the fuse sides when the wings are mounted. Nylon wing nuts are then put on the bolts from the inside of the fuse. Actually, for insurance, I put regular nylon nuts on first, then wing nuts over those. I like the nut and bolt method better.
