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. |
