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.

1. A dynamic fluid control surface of a vehicle, comprising:a dynamic fluid control surface having an internal chamber containing a pressurized fluid, a first edge, a second edge, an exterior surface, and one or more blowing slots positioned along the first edge, each said blowing slot having an opening in said exterior surface of said dynamic fluid control surface, wherein said internal chamber is connected to said one or more blowing slots; one or more piezoelectric actuators wherein each said piezoelectric actuator is mounted directly adjacent to one said opening of one said blowing slot such that the location of said piezoelectric actuator enhances the control of fluid through said blowing slot; and a means for controlling said one or more piezoelectric actuators, wherein when said means for controlling is engaged, said piezoelectric actuators cause a change in the flow of said fluid through said one or more blowing slots.
