Hey all, I have been trying to wrap my head around something, and it seems like I am missing something relatively simple.

Building a proper wing intersection fairing/fillet on a square fuselage seems pretty straight forward per Hoerner's study's.

Is the fillet simply extended beyond that of a perfectly square intersection? (When I say square I am referring to a straight sided fuselage at the point at which the wing meets. Which we all know is ideal)

In my head it seems as if you would take the point of max thickness and extend it to the trailing edge of the wing. But then to bring it back together? This is where I cant visualize it with a tapered fuse.

Mike Arnold does a great job explaining in one of his videos, but again I can only seem to apply it (in my head) to a straight fuse


For reference, I would like to build a fillet on the main wing of a Dragonfly.
