Summary:

Advanced aluminum manufacturing and assembly techniques are highlighted for next generation metallic wing and fuselage structures. When innovative design concepts that utilize the optimum product forms and new alloys are combined into an integrated solution, dramatic reductions in both cost and weight can be achieved. Several applications will be highlighted that utilize new emerging manufacturing processes and designs for the aerospace industry to obtain unique advantages over incumbent structures. Manufacturing demonstration examples will be discussed for Alloy 7055 and 2099 integrally stiffened panels that were friction stir welded.
