Keywords: Multi rib, Multi spar, Sandwich, Thick paste adhesive Abstract Conservatism in design and manufacturing has tempered the traditional innovative spirit. This A generic study of wing structure concepts is conservatism was caused by liability concerns presented. The wing concepts are classified and also by the nature of the marketplace. The according to the bending moment load path number of aerospace companies has been through the skins: reduced dramatically by consolidation, A. The load is sustained by the eliminating in particular smaller companies skins. The wing may be multi spar or multi rib. where innovations were most likely to occur. B. The load is sustained by the Of course, innovative concepts are still spars. Elastically buckled skins or emerging from surviving small, entrepreneurial sandwich skins with ±45º fiber companies such as Toyota Aviation [1] Scaled directions may be incorporated. Comp
