This project aims to study 3-Dimensional (3D) wing kinematics of a dragonfly (free-flying or controlled-flying) for designing micro air vehicles. Optical probing techniques will be used to measure the flexible wings kinematics during flapping of a dragonfly. The effect phase between the pair of forewings and flexible hind wings will be studied. Effect of wing flexibility on aerodynamics and vortex flows formation will be investigated. The kinematic parameters such as the wing tip trajectory, angle of attack and camber deformation were obtained from a 3D reconstruction technique that involves the use of fine grid projection for 3D profile measurements. High speed flow visualization and particle image velocimetry techniques will be used in the measurements.
