This project aims to take advantage of the automatic response birds have inflight to turbulent flow regions. By applying how they respond to these perturbation, these adaptations can be implemented to urban air mobility (UAM) aircraft, which operate in cities which are highly turbulent regions. To begin this project we first need to understand how birds, and in our case flapping flyers, react to controlled gusts. By using equipment designed and produced by Swansea postgraduates, measured gust can be sent towards Pigeons. The gusts in question are regions of unsteady flow, which will artificially increase the birds angle of attack. This will force the bird to manoeuvre to get back into steady, unaccelerating level flight. This response will be measured using motion capture software's as well as slow motion visual cameras and all will be collected in a multitude of different combinations in order to capture the mechanisms flapping flyers use to correct themselves. All of the data will be post processed, especially motion capture, to gain a numerical values in order to understand the response of the Pigeons as well as comparative data when, in the future, protypes replicating will have statistics to compare with. Once we understand what mechanisms the Pigeons are using for flight we may want to run CFD models where we can test prototypes which will try and recreate what the Pigeons have already achieved. This would reduce cost as less prototypes are going to built and they will likely have a higher success rate. However, depending on the complexity of the simulations, it maybe more time efficient to only consult the theoretical aspects and manufacture more prototypes to be tested at Bay campus. We then want to put prototypes through the same conditions the Pigeons were under. This will prove that the prototypes share the same gust rejection or not, and with faster speeds available in the wind tunnel at Bay, we will be able to see, to what extent the gust rejection learnt from the pigeons is applicable to.

该项目旨在利用鸟类在飞行到湍流区域时的自动反应能力。通过应用它们对这些扰动的响应方式，这些适应可以应用于在高度动荡地区的城市中运行的城市空中机动（UAM）飞机。要开始这个项目，我们首先需要了解鸟类（在我们的例子中是扑动的传单）如何对受控阵风做出反应。通过使用斯旺西研究生设计和生产的设备，可以将测量到的阵风发送给鸽子。所讨论的阵风是不稳定流的区域，这会人为地增加鸟类的迎角。这将迫使鸟进行机动以恢复稳定、不加速的水平飞行。这种反应将使用动作捕捉软件以及慢动作视觉相机进行测量，并且所有这些都将以多种不同的组合进行收集，以便捕捉扑动的传单用于自我纠正的机制。所有数据都将进行后期处理，特别是动作捕捉，以获得数值，以便了解鸽子的反应以及比较数据，以便将来复制原型时可以有统计数据进行比较。一旦我们了解了鸽子使用什么机制进行飞行，我们可能想要运行 CFD 模型，在其中我们可以测试原型，尝试重现鸽子已经取得的成就。这将降低成本，因为要建造的原型更少，并且成功率可能更高。然而，根据模拟的复杂性，仅参考理论方面并制造更多原型在湾校区进行测试可能会更节省时间。然后我们想让原型经历与鸽子相同的条件。这将证明原型机是否具有相同的阵风抑制能力，并且随着海湾风洞中可用的更快速度，我们将能够看到从鸽子那里学到的阵风抑制作用在多大程度上适用。
