论文摘要
本文与第二个ASDMAD（飞机设计的空气结构动力学方法）活动的名义上静态航空弹性极点的实验数据相比，提出了数值结果。为了进行模拟，应用了模块化求解器索非亚与流体侧的DLR求解器Tau结合使用，并应用了结构侧的内部求解器FEAFA。首先，引入了实验设置和气弹性求解器，然后对结果进行了详细的分析。提出了压力分布和全局提升系数的比较，以进行攻击角度，马赫数和空气动力学负载因子的变化。此外，本文还包含对激发振动的动态结果的初步研究，该振动应用了翼根区域中的周期内部力夫妇。
This paper presents numerical results in comparison with experimental data of nominally static aeroelastic polars of the second ASDMAD (Aero-Structural Dynamics Methods for Airplane Design) campaign conducted in the European Transonic Windtunnel. For the simulation the modular solver package SOFIA combined with the DLR solver TAU on the fluid side and the in-house solver FEAFA on the structural side is applied. First the experimental setup and the aeroelastic solver are introduced, followed by a detailed analysis of the results. Comparisons of pressure distributions and the global lift coefficients are presented for variations of angle of attack, Mach number and aerodynamic loading factor. Additionally, the paper contains preliminary investigations of dynamic results for excited vibration applying periodical inner force couples in the wing root area.
