Abstract : The current Air Force emphasis on fracture mechanics, design-to-cost, and low cost of ownership in the design of aircraft structures has caused adhesively bonded metal laminates to emerge as a promising concept for building primary aircraft structure. Recently completed analytical investigations indicate that adhesively bonded metallic laminated construction when applied to wing structure, can provide lower production and operating costs, increased safety through improved damage tolerance, and a weight savings over conventional type wing structure. The Laminated Wing Structures program was to establish low cost manufacturing techniques for an advanced laminated wing structure demonstration article that when compared to a baseline of current state-of-the-art construction will show improvements in the following areas: overall acquisition costs; improvements in damage tolerance to effect a significant life span increase; and overall structural weight. The F-16 Air Combat Fighter wing box was chosen as the baseline component for this program. The demonstration article was a section of the wing box taken from the wing root area where maximum bending occurs.
