At work, a colleague pointed me to some information from NASA about "isogrids", a method to design light-weight structures. I ran a google search and found this web site from NASA with a spreadsheet you can download to size the isogrid.

The web site is here <https://femci.gsfc.nasa.gov/Isogrid/>

The handbook referenced on the website lists other ways to use isogrids, including using them to stiffen tubular structures. I have seen these on some pictures of missiles and payload shrouds over satellites--even some composite golf club shafts).

I was wondering if anybody here has tried isogrids to build light-weight fin cans, motor mounts, etc. Might be a way to make airframes too.

Just wonderin'
