Forecast air traffic worldwide air has been a key skill for aircraft manufacturing companies. Even with deep market research, the risks of defining product characteristics are high. In this sense, finding ways to be more flexible with the market changes is important to maintain company competitiveness in the market. Even today, aeronautical manufacturing involves a large proportion of manual labor, which directly affects the production capacity of the industry. To meet the demand and give the dynamism that the industry must have to compensate for the changes that are dictated by the market, the understanding and modeling of the processes that occur in the production lines have become increasingly necessary, being labeled sometimes, as a primary factor for the competitiveness of aircraft manufacturing companies. Thus, in the constant search for business excellence focused on improving productivity and quality, large companies have sought to implement solutions that better describe their manufacturing processes. However, those firms that develop differentiated products and with reduced operating costs stand out. As a result, more importance has been given to manufacturing costs, expenses with non-quality, high production cycles, lack of standardization, and a large number of people involved in the process, which increases the final cost of the product. Therefore, concepts of Integrated Product Development (IPD) and Lean Product Development (LPD) have been shown to be increasingly important in the development of products that offer the lowest possible production cost coupled with high quality. In this sense, this thesis proposes the development of a design method that is capable of believably modeling aeronautical manufacturing processes, contemplating dimensional and geometric distortions intrinsic to the manufacturing process. Furthermore, this work seeks to clarify the manufacturing requirements and how they relate to the high-level requirements of other areas (e.g. aerodynamics and structures) through multidisciplinary analysis. The proposed method has been preliminarily applied to the design of an aircraft wing with very promising results. |
