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.

该项目旨在利用自动响应鸟类具有湍流区域的转移。通过应用它们对这些扰动的响应方式，可以将这些适应性实施到城市空气流动（UAM）飞机上，该飞机在高度动荡的地区运营。要开始这个项目，我们首先需要了解鸟类以及在我们的情况下如何拍打传单对受控阵风的反应。通过使用Swansea研究生设计和生产的设备，可以将测得的阵阵送到鸽子上。有问题的阵风是不稳定流动的区域，这将人为地增加鸟类的攻击角度。这将迫使鸟动作恢复稳定的，不可行的水平飞行。该响应将使用运动捕获软件和慢动作相机来衡量，所有响应将收集到多种不同的组合中，以捕获拍打传单来纠正自己的机制。所有数据都将在处理后，尤其是运动捕获，以获得数值，以了解鸽子的响应以及比较数据的何时，将来复制的ProTIPES将具有与之相比的统计信息。一旦我们了解了鸽子用于飞行的机制，我们可能希望运行CFD模型，我们可以在其中测试原型，这些原型将尝试重新创建鸽子已经取得的成就。由于原型的建造将减少，这将降低成本，并且成功率可能会更高。但是，根据模拟的复杂性，仅咨询理论方面并制造更多的原型要在Bay Campus进行测试，可能会有更多的时间效率。然后，我们希望将原型放在鸽子下面的相同条件下。这将证明原型是否共享相同的阵风排斥，并且在海湾的风隧道中可用的速度更快，我们将能够看到，从鸽子中学到的阵风排斥在多大程度上适用。
