I have the plans for a Great Lakes biplane. I rent one on occasion when I need to go do upside down stuff. cool plane, just I really hate how the wings are made.
2x (fore & aft) spruce spar, with 2017 aluminum stamped ribs screwed in with cad plated wood screws... wooden drag rib, internal tension wires, and compression tubes. It's like transition tech between full wood or full metal wings... and an absolute pain in the rear to make. Did I say wood screws hold the ribs on? Seriously I would rather sit there with a exacto razor saw and build up wooden ribs glued together with resorcinol... or better yet... I teach aircraft sheetmetal... I could make a sheetmetal wing EASY. Past that... I think composite wings on a biplane would be amazing, but I know NOTHING about composite design (would like to learn if someone would point me in the right direction)
I just don't know how to go about designing it properly.
What steps do I need to do?
each wing panel is held on with 2 bolt in double shear to the fuselage (lower) or upper wing section (upper). There are N struts out board obviously... and of course brace wires.
My primary concern is I'm worried about getting roughly equivalent stiffness in the wing... I dont want to build an immovable rigid wing that would overload the bolt joints. So my thought is to do a strength analysis of the truss structure. I've never done something like that's real/that complex.
I have solidworks with its Simulation add in...
What do I need to do to minimize the need of a) using a parachute and b) loosing my $30k engine in a wreck?
