The paper introduces an innovative methodology for efficiently designing intelligent de- formable aeronautical configurations capable of achieving predefined target shapes through the strategic adjustment of Shape Memory Alloy (SMA) actuators. SMA-based actuation plays a pivotal role in morphing concepts widely utilized in aeronautics, contributing to improved aerodynamic performance by dynamically altering wing geometry. The study presents a novel and robust algorithm specifically crafted to predict the nonlinear re- sponse within the SMA-structure interaction, further enhanced by its integration with an optimization method. This combined approach facilitates the accurate prediction of optimal structural and operational parameters aligned with the desired shapes for the controlled configuration. The design methodology, outlined in this research, meticulously selects key design parameters—such as the actuators’ placement and operational tem- perature—tailored to specific loading conditions. Different case studies are considered in order to showcase the implementation of the proposed approach.
