A morphing system’s performance is heavily affected by its physical design, manufacturing considerations and how it is operated. This project explores how these factors can be accounted for when using bio-inspired strategies to optimize the topology of a morphing wing’s airfoil. An L-system based approach is used to define the design variables that construct a graph based topology representing the airfoil’s internal structure and actuators, allowing for a wide range of airfoil designs to be considered. The discrepancies due to additive manufacturing limitations between the simulated and actual behavior of airfoils represented using graph based topologies are explored. Several objectives measuring how well a morphing wing aircraft can fly a trajectory are used to optimize an airfoil’s topology for effectiveness. These objectives include tracking performance on individual trajectories, tracking performance on worst case trajectories and the minimum flight times needed to reach pre-specified flight states. Results compare how well topologies optimized for these different objectives perform relative to each other.
