Man, that is cool....you be's the math expert!

I was fooling around in CompuFoil this morning and got it to loft a "wing" with elliptical "airfoils." The "root airfoil" (half ellipse) has a thicker % than the "tip airfoil" just for giggles and I had C/Foil loft a set of "ribs" on an elliptical planform (to get a set of bulkheads that will give a curved fuselage turtle-deck profile) with the "spars" (stringers) placed at the same % of chord so that you don't have to manually draw in all them stringers in CAD. I imported the resulting "ribs" as a .dxf into T/CAD and here's what I got. The span, chord and spar locations can all be changed as desired and C/Foil will happily loft all the necessary "ribs" (bulkheads.) That's gonna be good tool on the next airplane I do with a turtle deck. Should save some time!
