Pod Fit to the Wing

Pod Fit to the Wing

Number of Hours:  17
Manual Reference:  no ref

Yes another four long days has my pods tentatively affixed to the wing cuffs.

Here are my primary tools. The task is to fit the top of the pylons to the wings or rather the fitted wing cuff. They need to be in line and importantly with correct incidence witch is zero with the longerons already set at 2.2 degrees up.

Fitting just took hours and hours and dozens of refits. Then more hours. I removed a good inch or so of the rear of the pods and nothing at the very tip. The sides did need to be trimmed to fit the wing curvature. Of course I had to remove the same amount for the second pod so they would be a match. Anything else would cause more drag on one side and might tend to yaw the plane.

Finally they were getting close to in line. The required gap at the pylon to wing cuff is to be less than 1/8″ which is quite a large permitted error margin. Given there is a flox fillet and then 4 outside ply and 3 inside, well 1/8″ or more wouldn’t matter at all!

With the ends lined up I just need this incidence to be pretty close.

It is pretty close to a line drawn on the masking tape. That line was previously set of course.

Here we are showing a minimum gap and the cuffs and pods removed from the wing. How did that happen?

Once I was happy with the fit I added six 1″ square pieces of very lightweight glass. You can just see them in this pic. After they cured overnight I was able to remove the 6 screws holding the cuff and get the pods as a unit off the wings

The cuffs are quite securely held to the pylons as long as I am VERY careful. They are ready now for the 4 outer reinforcing plies.
