Slat noise includes: the interaction between the trailing edge and the leading edge of the slat, the high-speed airflow in the slat, and the trailing edge shedding vortex. The active control in this chapter is to reduce the interaction between the shedding vortex and the slat wing. If the active vibration control can move the shedding vortex outward and reduce the interaction between the shedding vortex and slat wing, it will have a good noise reduction effect.
