报告摘要：

In transonic regime, numerical simulation based on Computational Fluid Dynamics (CFD) techniques can provide reliable predictions for many transonic aeroelastic problems. However, due to high computational costs, it is hard to be accepted by aircraft designers. Furthermore, the order of aeroservoelastic system by using CFD techniques is too high for control law synthesis. Hence, it’s necessary to develop reduced-order aerodynamic model which can provide transonic unsteady aerodynamic loads more efficiently. In this presentation, a novel nonlinear aerodynamic Reduced-Order Model (ROM) is introduced for transonic aerodynamic system at first. Then, its applications in transonic aeroelasticity and aeroservoelasticity are demonstrated by several numerical cases.
