Aerodynamics of Drones for Offshore Wind Farm Monitoring

在过去的几年里，无人机已经扩展了完成广泛和多样化的民用和军事应用和任务的能力。然而，大规模应用基于无人机的技术的一个关键限制是设备的耐久性。本研究的目的是通过进一步探索种子激励飞行和其他被动推进模式的机理来提高小型无人机的续航能力。特别是，在简单的几何形状和非定常流动条件下，将在实验和数值两个水平上进行流固耦合和其他空气动力学特性的研究，以发展被动推进模式的新的和基础的知识。随后，开发的技术将扩展到设计和分析低阻力能量收集设备，为零能量和低能量运输提供新的工程解决方案。

Over the past few years, drone has extended the ability for accomplishing vast and diverse civilian and military applications and missions. However, a key limitation of the large-scale application of drone-based techniques is the endurance of the device. This research aims to enhance the endurance of small drones by further exploring the mechanisms of dandelion seed inspired flight and other passive propulsion modes. Particularly, investigations on the fluid-structure interaction and other aerodynamics characteris-tics with simple geometries and unsteady flow conditions will be carried out at both experimental and numerical levels to develop novel and fundamental knowledge about passive propulsion mode. Subsequently, the developed technique will be extended to design and analyse low-drag energy harvesting devices, contributing to new engineering solutions for zero-energy and low-energy transportation.
