Over the years I have seen some studies on the Zimmerman planform used on the Vought V-173, the reverse Zimmerman that almost makes a rounded delta wing, squares and circles.

On the other hand, I have not seen any formal analysis of straight-leading edge planform used so successfully on the Arups and related designs.

I’m especially curious to find out if anyone has experimented with a simplified, straight-line version of the Arup (like an octagon with three sides cut off) which would be much easier to build and integrate control surfaces.

Anyone have any leads?
