Natural fliers achieve exceptional aerodynamics by continuous adjustments on their geometry through a mix of dynamic wing compliance and distributed sensing and actuation. This enables them to routinely perform a wide range of manoeuvres including rapid turns, rolls, dives, and climbs with seeming ease. Despite a good knowledge of the physiology of bats and birds, engineering applications with active dynamic wing compliance capability are so far few and far-between. Recent advances in development of electroactive materials together with high-fidelity numerical/experimental methods provide a foundation to develop biologically-inspired dynamically-active wings that can achieve "on-demand" aerodynamic performance. However, this requires first to develop a thorough understanding of the dynamic coupling between the electro-mechanical structure of the membrane wing and its unsteady aerodynamics. In this collaborative initiative between the University of Southampton and Imperial College London, we will develop an integrated research programme that carries out high-fidelity experiments and computations to achieve a fundamental understanding of the dynamics of aero-electro-mechanical coupling in dynamically-actuated compliant wings. The goal is to utilise our understanding and devise control strategies that use integral actuation schemes to improve aerodynamic performance of membrane wings. The long-term goal of this project is to enable the use of soft robotics technology to build integrally-actuated wings for Micro Air Vehicles (MAV) that mimic the dynamic shape control capabilities of natural flyers.

天生的飞行员通过动态机翼柔顺性和分布式传感与驱动的结合不断调整其几何形状，从而实现卓越的空气动力学性能。这使得它们能够日常地执行各种动作，包括看似轻松的快速转弯、翻滚、俯冲和爬升。尽管人们对蝙蝠和鸟类的生理学有了很好的了解，但迄今为止，具有主动动态机翼柔顺能力的工程应用仍然很少。电活性材料开发的最新进展以及高保真数值/实验方法为开发可实现“按需”空气动力学性能的受生物启发的动态活性机翼奠定了基础。然而，这首先需要对膜翼的机电结构与其非定常空气动力学之间的动态耦合有透彻的了解。在南安普顿大学和伦敦帝国理工学院的这项合作计划中，我们将开发一个综合研究项目，进行高保真实验和计算，以基本了解动态驱动顺应性中航空机电耦合的动力学。翅膀。目标是利用我们的理解并设计控制策略，使用积分驱动方案来提高膜翼的空气动力学性能。该项目的长期目标是利用软机器人技术为微型飞行器（MAV）构建整体驱动机翼，模仿自然飞行器的动态形状控制能力。
