摘要

Differentially built up Al-alloy structures, using riveting and bonding processes have been proven successfully on aircraft structures over the last decades. This design has nearly permitted the highest degree of performance level and automation in production so that further weight and cost reduction is largely exhausted. Further improvements can only be obtained by a fundamental different design approach. EADS Airbus Germany has worked out within government funded technology projects new concepts for integrally stiffened fuselage structures using Laser Beam Welding technique. This challenge needs a highly interdisciplinary proceeding with respect to material, process, stress, design and assurance aspects. If we ask how did the design of the metallic fuselage structure changed within this period of the grown up Airbus family, the answer is: material processes, production and joining techniques were improved in a lot of aspects (New Al-alloys/Size of fuselage shells/Automation of manufacturing steps).
