Wing area 50 ft^2
Span 28ft
Gross weight: 500#
Airfoil 18% thick
Taper ratio : .7
Does anybody have any input regarding the vaibility of a wing with the following;
Removable, solid foam core, sandwiched with 3 ply carbon fiber @45 deg for the skins, substantial root and tip ribs, c-channel aft spar, full span flaperons. Im currently planning to use pre cured(on glass for surface quality) pre-preg carbon for skins. This ends up at .025"ish. 3 plies @45 will bend pretty well so I should just be able to bond it up to the cores and spars and put it under vacuum, with possibly some concessions to deal with the tight L.E. bend radius. I am some time out on this but am trying to wrap my head around the wing. Ultimately the main thing causing me to divert attention is educating myself on the airfoil. I want to design my own but this needs a good investment in time to do properly. The one constraint is that the main spar is already made and so I'm locked into a 18% thick airfoil. I am interested in feedback on the general construction techniques in terms of weight, manufacturability, durability and areodynamic effectiveness. Thanks for all your input, it helps me an incredible amount to be able to learn from others about this very complex set of skills. Rip it apart.
