Testing axial loads on a standard 10mm rod end, as I use it on my folding wing aircraft.
I remind you that the load that this rod end must withstand is approximately 1/5 of the total load on the wing, i.e. 120kg x 1/5 = 24kg
Load: 36kg which corresponds to 1.5g
Load: 156kg or 6.5g
Load: 181kg or 7.5g
Stayed more than 30 minutes under load of 181kg. No visible deformation of the rod end or of the support. And after that the rod end operates normally and without play.
This load of 181 kg is greater than the admissible 10% of the radial load recommended by the rod end manufacturers.
So we see that we can use a rod end the way I do to attach the wing to the plane, even if it’s unorthodox! I remind you that the 10mm rod end used for this test is quite standard and cheap! For greater safety, a high-strength 12mm one can be used, which could double the admissible load, i.e. 15g!
