The purpose of the research performed under this grant was to explore aerodynamics and flow-solid interactions of a flapping wing mechanism. This was accomplished by performing research in the following four areas: 1. Development and testing of a flapping mechanism featuring adjustable wing kinematics. 2. Exploration of different kinematic representations of flapping wing trajectories. 3. Study of hardware-in-the-loop optimization approaches. 4. Full-field, high-speed, three-dimensional flow imaging using synthetic aperture particle image velocimetry (SAPIV). The outcomes of these activities are summarized in the report. Where not available in publications or theses, methodological details are provided. It is shown that SAPIV is able to reconstruct 3D whole-field velocity fields in large spatial regions of interest. The results demonstrate that SAPIV can be used to measure fluid flow velocities and reconstruct the visual hull of flapping wings, benefiting future work in studying the complex and unsteady nature of flapping flight.
