Abstract：A series of wind tunnel test were performed to investigate flutter stability of twin streamline-liked sections in tandem. The test results were compared with those of single streamline-liked section. The study result show that flutter critical wind speed of twin streamline-liked sections is lower than that of single streamline-liked section and decreases with smaller distance; flutter frequency of twin streamline-liked sections is higher than that of single streamline-liked section and increases with smaller distance; the soft flutter characteristic of twin streamline-liked sections is more obvious compared with that of single streamline-liked section.
