The Manufacturing Cost Design Guide MCDG enables conceptual and detail designers of airframes to minimize cost by conducting trade-off analyses between the aircraft system performance objectives and specific manufacturing complexities over which the designers have control. This report describes this design tool which documents the relationships between airframe design features and producibility of both metallic and composite discrete parts and assemblies. The McDG highlights cost drivers associated with various structural designs and also the costs associated with competing manufacturing processes. The current program, discussed in this report, expands the two demonstration MCDG sections, i.e., composites and assemblies, developed previously. This program also enabled development of a new MCDG section for superplastic formed titanium airframe parts. The man-hours associated with test, inspection, and evaluation are frequently a cost driving factor when conducting realistic trade-off studies therefore, such data are also presented for use in the design process.
