A novel unsteady aerodynamic Reduced-Order Modeling method for transonic aeroelastic optimization

Abstract: In aircraft design, structural optimization and uncertainty quantification concerning transonic aeroelastic issues are computationally impractical, because the iterative process requires great number of aeroelastic analysis. Emerging Reduced-Order Model (ROM) method is convenient for transonic aeroelastic analysis. However, current ROMs cannot be reused during iteration, thus time cost is still way too large. This study proposed an improved ROM suitable for Arbitrary Mode Shapes (ROM-AMS), which is reusable re… Show more

“…When the loop becomes unstable, the deformations increase without or with oscillations (dynamic aeroelasticity), which can both lead to structural failures. Although understood, research is still highly active in this area, aiming to increase the accuracy in predictions and efficiency of such tools [15][16][17]. Linear models in the calculation of flutter have been proposed by Stancui [18].…”

“…虽然 KMC 方法与微尺度方法相比,通过降低时 间尺度上的分辨率而更具有效率优势, 但其在空间上 仍然具有分子尺度,因此在 CFD 计算的每一个网格、 每一次迭代中都进行 KMC 模拟是不现实的.近年来, 机器学习方法已经成功应用于流体力学 [23] 、流-热-固 耦合 [24] 、气动热 [25]…”
