Need formula for solving ellipse radius with equal spacing points

I'm trying to build an oval bicycle wheel and need a formula to calculate the radii so that I can use the results to calculate the length for each spoke. See diagram for details. Hope someone can help.

The OP posted this question at another site, and we discovered he wants the perimeter of the ellipse to be divided into equal segments. They were then advised of numerical methods for achieving this goal.
