Birds have a remarkable agility and robustness in flight, able to cope with turbulent flows or even blustery conditions and still perform extraordinary aerial manoeuvres. The increasing number of applications arising for Unmanned Air Vehicles (UAVs) during the past decade has highlighted the importance of improvements to their endurance in flight. Their rigid wings, together with their small size and elementary control systems, make them vulnerable against gusty and turbulent environments. Birds' inherent manoeuvrability in flight is fed by a complex sensorimotor loop, together with the ability to morph their wings to change sweep, span and area, to respond to a disturbance in the flowfield. In recent years, an increasing amount of research has been focussed on the study of avian flight, with the goal of improving the performance of small UAVs. This research will analyse the flight dynamics data collected at RMIT University (Melbourne) of a kestrel in a wind tunnel, to then design and build an avian-inspired robotic wing. The wing will then be tested in wind tunnels at the University of Bristol, with the aim of reducing turbulence and gust disturbances. The proposed timeline for the completion of this project will be 3.5 years, where the second year will take place at RMIT University in Australia.

鸟类在飞行中具有非凡的敏捷性和健壮性，能够应对湍急的气流甚至狂风天气，并仍能进行非凡的空中机动。在过去的十年里，无人机(UAV)的应用越来越多，这突显了提高其飞行耐力的重要性。它们坚硬的翅膀，加上它们的小尺寸和基本的控制系统，使它们在阵风和动荡的环境中很容易受到攻击。鸟类在飞行中固有的机动性是由复杂的感应器回路提供的，加上改变翅膀以改变掠过、跨度和面积的能力，以对流场中的扰动做出反应。近年来，越来越多的研究集中在鸟类飞行的研究上，目的是为了提高小型无人机的性能。这项研究将分析RMIT大学(墨尔本)收集的一只红隼在风洞中的飞行动力学数据，然后设计和制造一种以鸟类为灵感的机器翅膀。随后，该机翼将在布里斯托尔大学的风洞中进行测试，目的是减少湍流和阵风干扰。该项目的拟议完成时间表为3.5年，第二年将在澳大利亚的RMIT大学进行。
