Abstract:A mechatronic setup is used to study the flight dynamics of an ornithopter in a wind tunnel. The amount of pitching, flapping frequency and wind speed can be controlled individually and their influence on a flexible wing are analyzed through a series of experiments. A stereo vision setup and corresponding tracking algorithm are used to create a digital reconstruction of the wing's 3D motion. In addition, force, power and efficiency measurements were performed and particle image velocimetry was used to determine the effects of the wing on the air flow. The resulting dataset forms a basis for research on ornithopter flight and biomimetics, as well as further development of robotic birds and aerodynamical models. For the setup considered here, results showed that in order to optimize the generation of thrust, the amount of twisting of the wing should decrease as air speed increases. The stereo vision measurements revealed that wind speed dominated pitching angles and consequently angle of attack due to the wing's flexibility.
