Abstract

A strong candidate for morphing wing design is the folding wing configuration. In the process of morphing, the flutter properties of folding wing aircraft will change dramatically due to different wing configurations throughout the folding process. To increase efficiency, this process was simulated by a quasi-static method instead of real-time simulation. Parametric studies were performed to analyze the flutter characteristics of the folding wing aircraft. The results show that if the folding angle falls into the middle range of morphing, the flutter speed pressure will decrease and stiffness of folding actuator has an obvious impact on flutter speed pressure of the folding wing aircraft.
