Brief Description: 2: Wing Wiring Conduits
|
|
While I was waiting for the paint to dry on my aileron control rods, I thought I may as well tackle the task of working out how to get the tip lighting and servo motor wiring run through the wings.
On the right wing, I've already used the pre-drilled wiring/tubing holes for my AoA sensor, and since my RV is a quick build, then it would be very diffiult to drill holes through the inboard wing ribs as they're already covered by the inboard skin. Not impossible, just difficult.
I then came up with the idea of supporting a rigid conduit within the lightening holes with a series of shop made brackets. I eventually settled on the design you see in my pictures below, with my brackets made from some scrap 0.030" aluminium.
I actually installed two conduits. One from the wing root out to the servo motor, and one from the servo motor out to the wing tip, with a good size gap between the two. This will make running my servo motor and wing tip lighting cables very easy, even after the final skins are fitted.
One end of each conduit is fitted with a locking nut to prevent any movement. I'm also going to add some dobs of silicon in key spots to minimise the effects of vibration.
When installing my brackets, I put the manufactured head of the blind rivets underneath the rib flange. That way I figure it will have minimal interference when trying to buck the wing skin rivets (a job I'm not looking forward to).
NOTE: I've got a detailed sketch of my bracket design, with dimensions, if anyone wants. Just send me an email.

I broke the conduit near the servo motor, for obvious reason
