The airfoil trailing edge porous materials for reduced acoustic emissions, which were investigated during the last funding period, were generated by stochastic processes. In order to have better control over the materi-al properties and to allow for a gradual change in material parameters, it is desirable to generate porous material with defined microstructures by 3D printing. In this project, the microstructure of a porous medium for a given graded material or a given transport parameters will be derived under consideration of manufac-turing uncertainties using robust optimization.

翼型后缘多孔材料减少声发射，这是在最后一个资助期间进行了研究，产生的随机过程。为了更好地控制材料性能并允许材料参数的逐渐变化，期望通过3D打印生成具有限定的微结构的多孔材料。在本计画中，将利用稳健最佳化方法，在考虑制造不确定性的情况下，推导出给定梯度材料或给定输运参数的多孔介质的微结构。
