© 31st Congress of the International Council of the Aeronautical Sciences, ICAS 2018. All rights reserved.Conventional transport aircrafts are becoming more flexible in order to achieve lower fuel consumption. Most part of the additional flexibility comes from the increased wing aspect ratio. This line of studies is composed by sequential phases which come from Aerodynamics to Structures passing through Loads and Aeroelasticity technologies. This work proposes the integration of Aerodynamics and Structures through a multidisciplinary analysis, focusing on the high flexibility aspects of the wing in-flight shape for a recent, high aspect ratio aircraft. This work aims to understand the changes in the loads and structural sizing processes due to the increased flexibility of the wing. It uses a recent and high aspect ratio aircraft as a study case. Potential Computational Fluid Dynamics and nonlinear Finite Elements Method analyses are integrated employed in this study. Large displacements was included in the process, showing impacts for future development methodologies.
