abstract: The study of flexible flapping wings of natural flyers and micro air vehicles remains challenging by the problem’s unsteadiness, nonlinearity, moving boundary and strong fluid-structure interaction. In the first part of the talk, a fully-coupled method will be introduced to solve flapping-wing aerodynamics. In the second part, an adjoint-based approach is applied for the optimization and control of the shape and moving trajectory of flapping wings. Using the idea from non-cylindrical shape (or tube) analysis, we are able to derive an adjoint-based analysis in a rigorous and simple manner for the optimization of moving/morphing objects. At the end, model reduction and other related work will be briefly discussed.
