Birds have deployable covert feathers that are hypothesized to aid in aerodynamic flow control. Inspired by this biological control solution, we use high-fidelity simulations to explore a simplified configuration in which a flat plate is mounted via a torsional spring on an airfoil. We first characterize what dynamical regimes this system can undergo for various spring and inertia values, explaining some of the underlying fluid-structure interaction mechanism and their implications on performance changes.
