Guys I have a question about a biplane design I'm working on.
Both wings have a constant 15" chord. I'm planning on staggering the upper wing about 3 to 4 inches ahead of the bottom wing. My question is knowing this do I still need a 15" gap between the wings for efficient aerodynamics? Or can I move the gap closer say 12" or so?
Any help would be appreciated. I'd like to design a slow fliying biplane with 48" span wings. The airfoil is a thick flat bottomed Clark Y type.
Thanks for the input.
Tom
