Impact of Integral Structures in the Design for Manufacture and Assembly of Airframes
From a lean philosophy viewpoint, the huge amount of fasteners used in airframes appears to be the inverse of what the design for manufacturing should seek. New design concepts with integral joints may be produced using welding processes, simplifying and optimizing the design for manufacturing and assembly process; however, crack arrest capability may be compromised. An introductory quality function deployment (QFD) analysis applying the Cross method evaluates the main design goals in the application of new joining processes in lightweight reinforced structures. The analysis shows that new welding process can improve airframe structures provided the structural integrity is ensured.
