Abstract: The control laws of active flutter suppresion system for a low aspect ratio wing flutter model with outboard missile are studied. The model is equipped with an outboard trailing-edge control surface. Firstly, according to all dynamic characteristics and rigid characteristics of the model, a second order control law is designed using a dynamic compensator method based on the optimum control. Further, the control law is tested by the simulator during a wind-tunnel test. The experimental results indicate that the flutter critical speed increases by more than 14 percent. The calculated results are in good agreement with the experimental ones.

Key words: flutter, active suppression, wing/store
