I need to know how to find the mean aerodynamic chord for a tandem wing aircraft.
I can find plenty on normal configurations, straight wings, tapered wings, delta wings, and canard aircraft. What I want is for an actual "tandem wing", not a canard.
The Delanne aircraft represent the type I'm thinking of. Basically, a normally configured aircraft, except the stabilizer is almost as large as the main wing (75-90%) and is aproximatley 1.5 to 2.0 times the main wing's chord back.
The Mauboussin Hemiptere is another example.
These are planes with two decent sized lifting surfaces, with the elevator or attitude controls on the rear wing (ailerons too sometimes).
I cannot find a definitive case of how to find the mean aero. chord - necessary of course to estimate CG, neutral point, and so on.
Any help is greatly appreciated.

Bill
