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.

本研究的目的是发展一种基于混合仿真方法的新一代动态风洞试验技术，用于研究飞机在非线性飞行区域的动态稳定性。设计、制造了一种新型的并联机械手“HEXA”，用于进行多自由度动态风洞试验。此外，还发展了先进的光学测量技术，如非定常压敏涂料和荧光微束，以显示模型在流动中运动的流动。通过这些技术的实验，阐明了振动频率和振幅对机翼动态稳定性的影响。
