RESUMO

Brazilian aeronautical industry has been developed faster and faster in terms of technology development and manufacturing processes. Thus, it has been planning to reach better results during the aircraft development and manufacturing phases, aiming to better evaluation of manufacturing processes, assembly, maintenance, capability and human factors (ergonomics). It is expected to improve the manufacturing and simplify the assembly to become easier the manufacturing of parts that will make the aircraft final assembly with low costs, high quality and the best optimized condition. So, the main objective of this study is to develop a guideline which uses the DFMA concepts for specific application on aircrafts design and manufacturing. The main goal of the guideline is to drive the engineers who work on aircraft development phases, about the manufacturing benefits that can be achieved when using the check list table of the guideline. This study starts with the aviation history and world and brazilian aeronautical industries and a theoretical review of the principles and concepts of the Design for Manufacturing and Assembly (DFMA) methodology. Next, the study describes the aeronautical industry environment, including the process of product integrated development, the implementation of projects in this sector and the airplane manufacturing phases. Subsequently, it has shown the guideline routine, which was developed in form of check list tables that contain rules and steps to be followed during the design creation and attempts to consolidate manufacturing knowledge and to prevent possible assemblies discrepancies. A case study is also presented to evident and makes the comparison between the results of aeronautical design that had been developed without DFMA concepts and post benefits reached after the project revision using the design for assembly concept and guideline tables. Finally, the results are discussed and the conclusion established.
