This project aims to produce a deeper understanding of the role of wingtip feathers in the remarkable abilities of birds to fly in unsteady and unpredictable aerodynamic environments, and in some cases to do so almost silently. This is achieved by developing novel numerical methods integrating fluid, structure and acoustics interactions for large deformations and complex geometries. The numerical results are validated and complemented by using flow, structure and acoustics experiments on dynamically scaled models. The insight gained provides design guidance for more efficient, robust and stable flight of bio-inspired micro air vehicles, and in reducing the noise impact of wind turbines by innovative blade leading edge and tip shaping.

该项目旨在更深入地了解翅膀羽毛在鸟类在不稳定和不可预测的空气动力学环境中飞行的显着能力中的作用，在某些情况下几乎可以默默地这样做。这是通过开发新的数值方法来实现的，该方法将流体，结构和声学相互作用整合起来，以实现大变形和复杂的几何形状。通过在动态缩放模型上使用流，结构和声学实验来验证和补充数值结果。获得的洞察力提供了设计指南，可为生物启发的微型空气车的效率更高，稳定和稳定，并通过创新的刀片前缘和尖端塑造来降低风力涡轮机对风力涡轮机的噪音影响。
