Journal of Biomechanical Science and Engineering, 2018 Insect wings change its shape passively by the aerodynamic and inertial forces when flapping, which can greatly affect its aerodynamic performances. In order to confirm the importance of the fluid-structure interaction in flapping wing aerodynamics, we ...

Flapping‐Wing Dynamics as a Natural Detector of Wind Direction
Advanced Intelligent Systems, 2021 Flapping‐wing unmanned aerial vehicles have potential advantages, such as consuming lower energy by leveraging the force of wind. Since the flapping movements of the soft wings contain information about the wind, measuring the movement of each part of ...
