A method and system 10 for controlling fluid flow 12 in relation to a body or foil 14. The system 10 has one or more channels 16, at least some of which having an inlet port 18 and an outlet port 20 defined in the foil 14 through which at least some of the fluid 12 may flow. The inlet port 18 is defined adjacent to a leading edge region 22 of the foil 14 and the outlet port 20 is located in a another region 24 of the foil. Optionally, a differential vectoring means 24 provides a differential mass flow rate across the foil 14 to provide a resultant force that in one illustrative environment creates, enhances, or stops a rolling action of the foil 14.

The system of claim 1, wherein the flow state sensed by the sensing signal (S1) is an incipient stall condition. 3. The system of claim 2, wherein the activation signal (S2) moves the valve mechanism so that more fluid is directed to an outlet located beneath a trailing edge of a descending foil. 4. The system of claim 3, wherein the activation signal (S2) moves the valve mechanism so that more fluid is directed to an outlet located above an ascending foil. 5. The system of claim 1, wherein the valve mechanism includes one or more valves associated with at least some of the outlet ports. 6. The system of claim 1, wherein at least some of the one or more inlet and outlet ports are characterized by an aperture, the diameter of which can be changed by the signal (S2) from the control module. 7. A system for controlling fluid flow in relation to a body, comprising: a flow control means for controlling flow with one or more channels that have one or more inlet ports and one or more stationary outlet ports defined at least partially in the body through which at least some of the fluid may flow, the one or more inlet ports being defined adjacent to a leading region of the body and the one or more outlet ports being located in another region of the body;a differential vectoring means for providing a mass flow rate through and across the body to provide a resultant force that creates a turning moment upon the body, the turning moment being able to be used to create, inhibit or enhance the body's roll, pitch or yaw behavior;wherein the differential vectoring means includes a control module in communication with a valve mechanism positioned upstream of the one or more outlet ports, the control module having a sensor input that receives a signal (S3) from an operator of a vehicle with which the foil is associated, the signal (S2) from the control module being relayed to the valve mechanism.
