STUDY ON BUFFETING ACTIVE CONTROL BASED ON MACRO FIBER COMPOSITES
Macro fiber composites（MFC） have a good application prospect in aeroelastic buffeting control. The MFC actuator was modeled using the load simulation method. The aerodynamic forces were simulated by the doublet-lattice method and the control laws were designed applying the negative velocity feedback...

| description | Macro fiber composites（MFC） have a good application prospect in aeroelastic buffeting control. The MFC actuator was modeled using the load simulation method. The aerodynamic forces were simulated by the doublet-lattice method and the control laws were designed applying the negative velocity feedback algorithm. The influences of airflow velocity on the inherent characteristics of vertical tail and the control mechanism of buffeting active control were studied. The results show that the airflow velocity affects the inherent characteristics of the vertical tail. The additional aerodynamic force,mainly including the part which is inverse phase with the velocity,plays an additional damping role on the system below the flutter velocity. The piezoelectric driving force can even do positive work,but can make the additional aerodynamic force consume more energy so that the total energy consumption of the system increases. The results can provide useful reference for the practical buffeting active control and its application. |
