I seem to recall some article about an advanced fighter aircraft that
used corrugated webs in the spars somewhere. It's like the floor beams
where there is a thin piece of plywood between two solid beams as wide as
square. Imagine this webbing replaced with corrugated metal, with the bends
in the vertical arrangement. Likely to be a pain to build, unless you bury
it in epoxy in the frame caps, but it's a pretty cool design.
Unfortunately, I'm not sure penetrations for assorted reasons do so well in
it, although I haven't seen how it would be done.
