A dynamic fluid control surface, e.g., a rotor blade of a helicopter, having a blowing slot extending the entire length of the leading and trailing edges of the dynamic fluid control surface, an internal chamber containing a pressurized fluid, e.g., air, and one or more piezoelectric actuators positioned along the length of the blowing slots and connected to the internal chamber. The piezoelectric actuators are controlled by a computer system to regulate the flow of fluid released through the blowing slot. There may be one or more blowing slots on either just the trailing edge of a dynamic fluid control surface or on both the leading edge and the trailing edge of the dynamic fluid control surface.
