| Research Abstract |
The purpose of this study is to develop a next-generation dynamic wind-tunnel testing technique based on hybrid-simulation approach for studying dynamic stability of aircraft in nonlinear flight region. A new parallel-link robotic manipulator called “HEXA" has been designed, built, and used for conducting multi-degree-of-freedom dynamic wind-tunnel testing. In addition, advanced optical measurement techniques such as unsteady Pressure-Sensitive Paint and Fluorescent Mini-tuft have been developed to visualize the flow on the model moving in the flow. As a result of the experiment using these techniques, the effects of oscillation frequency and amplitude on the dynamic stability of a wing have been clarified.
