Introducing porosity onto an aerofoil has been shown to have a significant influence on the boundary layer and provide significant reductions in its noise radiation. This proposal describes a multi-disciplinary research project aimed at understanding and exploiting the interactions between porous aerofoils and the boundary layers developing over them for the purpose of optimising noise reductions without compromising aerodynamic performance. The use of adaptive manufacturing technology will be investigated for providing the optimum porosity at different operating conditions.

在翼型上引入孔隙度已被证明对边界层有显著影响，并显著降低其噪声辐射。这项建议描述了一个多学科研究项目，旨在了解和利用多孔翼型与在其上发展的边界层之间的相互作用，目的是在不影响气动性能的情况下优化降噪。将研究自适应制造技术的使用，以在不同的操作条件下提供最佳孔隙率。
