Aeroelastic fluid interactions are responsible for creating a range of excitation phenomena that can have detrimental impacts upon rotordynamic structures. The most common source of vibration in low flow speeds is dynamic stall, which occurs due to an increase in the angle of attack of the incoming flow. This stall causes flow separation and vortex shedding that induces a vibration response on the structure, this response causes fatigue damage to structures and reduces the service life of components. Previous studies (Elmadih) identify the use of lattice structures embedded into materials using Additive Manufacturing (AM) as a method of attenuating these vibrations, this proposal outlines a methodology for testing the effectiveness of material lattice structures using theoretical, computational and experimental means.

气动弹性流体相互作用是造成一系列激励现象的原因，这些激励现象可能对转子动力学结构产生有害影响。在低流速下最常见的振动源是动态失速，其发生是由于来流的攻角增加。这种失速会导致气流分离和旋涡脱落，从而在结构上引起振动响应，这种响应会导致结构疲劳损坏并缩短部件的使用寿命。以前的研究（Elmadih）确定了使用增材制造（AM）嵌入材料中的晶格结构作为衰减这些振动的方法，该提案概述了使用理论，计算和实验手段测试材料晶格结构有效性的方法。
