An unusual aeroelastic phenomenon was discovered in early wind tunnel test, where deformation of the high-aspect-ratio wing model used in the test suddenly decreases before flutter. In order to figure out the reason of the phenomenon, a new simulation frame is established and a series of high-aspect-ratio wings are designed. The wind tunnel tests are planned to be conducted.
