Hello all
I am starting to design a small aerobatic biplane (around 25" MAYBE up toward 30" wingspan if I have to) modeled after the Steen Skybolt ( http://www.steenaero.com/ .) I would like strong aerobatic performance with respectable speed. My current questions are...
1) What airfoil would be good for this size and type of plane?
2) What range wing loading should I shoot for? I don't want the super light "leaf with a powerplant" effect like the 3D purpose-built airframes. I want this plane to fly like it has an airfoil for a reason and therefore I'd like there to be a decent amount of energy retention. In other words I'd like it to fly on its wings not its prop.
3) When calculating wing loading, is there a difference in how a biplane uses it total wing area compared to a monoplane? Or is there some sort of adjustment due to the wings being in close proximity to each other?
4) Are these parameters too ambitious for a plane this size?
That's all for now.
Thanks
John
