ABSTRACT:
A method for joining the upper surface of a wing to its lower surface during assembly of the wing, and a novel internal wing structure. The method and structure uses multiple overlapping rib pairs. A rib is attached to the upper surface of the wing and overlaps an identical rib attached to the lower surface when the two surfaces are brought together at the leading and trailing edges. The two ribs so disposed are flush, one lying next to another with a rib spar hole in each rib matching an identical hole in the other of the pair. Wing spars are then inserted into the wing spar holes. In this manner wing spar alignment and attachment is simplified, and the upper and lower surfaces of the wings are mated.
