“…However, in the preliminary design stage, aeroelastic analysis employing more simple fluid-structure interaction analysis models is preferable than the computational structural dynamics-computational fluid dynamics coupled model due to the problems of the computational time and cost [9,10]. In addition, a more accurately description of wake effects on the airloads and aeroelastic behavior is the main challenge [9]. The linear inflow model is one of the most commonly used approaches for estimating an induced inflow ratio; however, this model fails to accurately describe the real physics as it does not often account for unsteady three-dimensional aerodynamic effects, which may have critical impact on aerodynamic damping [9].…”
