Manoeuvrability of unmanned air vehicles in complex environment is critically important and is extremely challenging. The complexity of the environment leads to turbulent conditions and improving the performance and efficiency of UAVs under these conditions require deep understanding of the aerodynamic phenomena of wings in turbulent environment. In this project, the aim is to carry out a range of high-fidelity experiments to understand the flow over rigid and flexible wings in turbulent conditions. Wind tunnel experiments will be designed, developed and carried out where the inflow will be systematically varied (to different turbulent conditions) and performance of wings will be measured. The experiments will range from time-resolved force and moment measurements to advanced image-based diagnostics to measurements the flow and the structural deformations of rigid and flexible wings. The resulting data will be analysed to gain a deep understanding of the phenomena as well as extract simple aerodynamic models that can be used for flow and flight control.

无人机在复杂环境中的机动性至关重要，也极具挑战性。环境的复杂性导致了湍流条件的产生，提高无人机在这些条件下的性能和效率需要深入了解湍流环境下机翼的空气动力学现象。在这个项目中，目的是进行一系列高保真实验，以了解湍流条件下刚性和柔性机翼上的流动。将设计、开发和进行风洞实验，其中将系统地改变流入量（不同的湍流条件），并测量机翼的性能。实验范围从时间分辨力和力矩测量到先进的基于图像的诊断，再到测量刚性和柔性机翼的流动和结构变形。将对所得数据进行分析，以深入了解这些现象，并提取可用于流动和飞行控制的简单空气动力学模型。
