Biplane design

[tobyskywalker]

Hi everyone!

I'm truly involve with the design of biplanes but I have got a big problem, does anyone knows how to calculate the wing lift slope of a biplane configuration?

Does any one knows how to calculate it according the stagger, decalage or gap, or even with the Munk's factor?

Because right now I'm using the non lifting line theory equations of prandtl.. but these are for monoplanes!.

Thank you, I need help urgent...
