Analysis of Axiomatic Design Influence on Aircraft Design Process

Today, product design has experienced fundamental changes. Design criteria have changed from focusing on product performance to sustainable criteria. This has increased the contrast between traditional and new requirements and consequently increases the design complexity. In this regard, traditional methods are incapable of solving the problems of product design. Therefore, many efforts have been made to solve these challenges to improve the design process. As a result of these efforts, various design methodologies such as multidisciplinary design optimization and knowledge-based engineering were developed. These approaches could support the evolutionary improvement of current product designs or the study of the novel complex product or could reduce the coupling between various FRs and design parameters (DPs). In this article, the authors discuss the effect of using the Axiomatic Design approach in the aircraft conceptual design process. The results obtained in this study indicate the high efficiency of this method in reducing the coupling between the FRs defined for the aircraft, as well as in reducing repetitive activities, thus optimizing the time and cost of the aircraft design process.
