THAT WHICH IS CLAIMED:

1. A system for generating lift provided by a multi-element aircraft wing comprising:
a main wing element;
a slat interconnected to the main wing element;
a flap interconnected to the main wing element;
at least one port defined in at least one of the slat, main wing element, and flap; and
at least one fluidic device operable to regulate fluid flow into and out of the at least one port to control boundary layer flow over at least one of the slat, main wing element, and flap.

2. The system according to Claim 1, wherein at least one fluidic device comprises one of an electromagnetic actuator, a piezoelectric actuator, a combustion-based actuator, a diaphragm, a piston, and a pump.

3. The system according to Claim 1, wherein at least one fluidic device employs zero net mass flow to regulate fluid flow through the port.

4. The system according to Claim 1, wherein at least one fluidic device is operable to actuate a plurality of ports such that fluid flows through each of the actuated ports simultaneously.

5. The system according to Claim 4, wherein at least one fluidic device is operable to actuate at least one port associated with at least one of the slat, main wing element, and flap.

6. The system according to Claim 1, wherein at least one port is defined in an upper surface of at least one of the slat, main wing element, and flap.

7. The system according to Claim 1, wherein at least one port is defined in an aft portion of at least one of the slat and the main wing element.

8. The system according to Claim 1, wherein each fluidic device is operable to actuate a respective port.

9. The system according to Claim 1, wherein each of the slat and flap is operably interconnected to the main wing element such that an angle of deflection of the slat and flap is capable of being adjusted with respect to the main wing element.

10. A system for generating lift provided by a multi-element aircraft wing comprising:
a plurality of wing elements, wherein each of the wing elements is operatively interconnected to each other;
at least one port defined in at least one of the wing elements; and
at least one fluidic device operable to regulate fluid flow into and out of the at least one port to control boundary layer flow over at least one the wing elements.

11. The system according to Claim 10, wherein the plurality of wing elements comprises a slat, a main wing element, and a flap.

12. The system according to Claim 10, wherein each fluidic device is operable to regulate a respective port.

13. The system according to Claim 10, wherein the wing elements are interconnected such that an angle of deflection of one wing element is adjustable with respect to another wing element.

14. A method for increasing lift of an aircraft comprising:
initiating fluid flow over a multi-element aircraft wing comprising a plurality of wing elements; and
regulating fluid flow through at least one port defined in at least one of the wing elements to control boundary layer flow over at least one of the wing elements.

15. The method according to Claim 14, wherein initiating comprises initiating take-off or landing of the aircraft.

16. The method according to Claim 14, wherein regulating comprises actuating a fluidic device associated with at least one port.

17. The method according to Claim 16, wherein actuating comprises actuating a plurality of ports simultaneously.

18. The method according to Claim 16, wherein actuating comprises actuating at least one port associated with at least one of the wing elements.

19. The method according to Claim 14, wherein regulating comprises ingesting fluid into a respective port or expelling fluid from a respective port.

20. The method according to Claim 14, further comprising adjusting an angle of deflection of at least one of the wing elements with respect to another wing element.
