This paper presents a numerical methodology for designing and studying high aspect ratio composite baseline wings equipped with passive control systems, namely Folding WingTip (FWT) and Twist WingTip (TWT) devices, with the primary objective of enhancing gust load alleviation. The methodology integrates Finite Element (FE) software and a Reduced Order Model (ROM) framework for dynamic aeroelastic analyses, all within the Nonlinear Aeroelastic Simulation Software (NAS2) package, facilitating streamlined aeroelastic design of composite wings equipped with wingtip devices. NAS2 serves as a reliable and efficient platform for coupling diverse simulation codes, thereby enabling precise simulation of the interaction between aerodynamics and structures. To examine the impact of wingtip devices, we will use a previously established baseline wing design [7]. The design aimed to optimize high aspect ratio composite wings by minimizing weight while considering structural, material, aeroelastic, and manufacturing limitations. The baseline wing is equipped with Folding Wingtip (FWT) and Twist Wingtip (TWT) devices to study their impact on Gust Load Alleviation (GLA). The present study evaluates the
effectiveness of these wingtip devices in reducing gust load, with a particular focus on the root bending moment. It allows for a comprehensive comparison of gust responses between the baseline wing and the wing equipped with these passive wingtip devices.
