| Abstract: | The viscosity of electrorheological (ER) fluid can be changed by varying the applied electric field. By using ER fluid as the damping medium, a new type of damping pivot was designed and used to suppress the flutter of a control canard model. The ER pivot was installed on the rotating axle of the control canard model, a set of leaf springs was used to simulate the flexibility of the pitching stiffness of the canard. Wind tunnel tests were performed and on/off control law was adopted. Results show that the critical flutter speed of the model is increased by 13 %. |
