Abstract

A high lift system with a main wing and regulating flaps, also bearing devices for the mounting of the regulating flaps, and positioning devices for the positioning of the regulating flaps, wherein the respective bearing device and/or positioning device is at least partially provided with a fairing, having a flow control device for purposes of controlling the flow around the high lift system with at least one inlet duct with at least one inlet, which device is located on or underneath the lower face of the high lift system, wherein at least one outlet duct for air is furthermore provided, which is connected with the inlet duct in a fluid-communicating manner, and has at least one outlet, which is located on the upper face in the region of at least one regulating flap of the high lift system.

First claim

What is claimed is:

1. A high lift system comprising:
a main wing,
at least one regulating flap coupled to the main wing,
at least one guiding device configured to guide the movement of the at least one regulating flap,
at least one adjusting device configured to adjust the at least one regulating flap,
a fairing, and
a flow control device configured to control the flow around the high lift system and comprising:
at least one inlet duct comprising:
at least one inlet,
wherein the at least one inlet is located on or underneath a lower face of the high lift system,
wherein the lower face of the high lift system faces a pressure side of the at least one regulating flap,

at least one outlet duct connected with the inlet duct in a fluid-communicating manner, and comprising:
at least one outlet,
wherein the at least one outlet is located on an upper face of the high lift system in the region of the at least one regulating flap,
wherein the upper face of the high lift system faces a suction side of the at least one regulating flap;

wherein at least one of the respective guiding devices and adjusting devices are at least partially provided within the fairing,
wherein the flow control device is arranged at least partially within the fairing and the inlet duct at the location of the at least one inlet runs along the main wing chordwise direction.

2. The high lift system in accordance with claim 1 , wherein the at least one inlet is configured as an opening in the fairing and is disposed at a region of the fairing which is facing the main wing chordwise direction.

3. The high lift system in accordance with claim 1 , wherein an inlet opening and closing device is provided for the at least one inlet.

4. The high lift system in accordance with claim 1 , wherein an outlet opening and closing device is provided for the at least one outlet.

5. The high lift system in accordance with claim 3 , wherein the inlet opening and closing device is coupled kinematically with the at least one adjusting device for a regulating flap of the high lift system, such that the opening status of the inlet opening and closing device is determined by the setting of the regulating flap.

6. The high lift system in accordance with claim 5 , wherein a degree of the opening of the inlet opening and closing device is a function of the setting of the regulating flap.

7. The high lift system in accordance with claim 1 , wherein a control valve or a pump is provided in at least one of the at least one inlet duct and in the at least one outlet duct to control the volumetric flow within the flow control device.

8. The high lift system in accordance with claim 1 , wherein a flow variator is provided for systematic variation of the flow of air through the flow control device.

9. The high lift system in accordance with claim 8 , wherein the flow variator is configured as a passively operating valve or as a pump.

10. The high lift system in accordance with claim 8 , wherein the flow variator is arranged in the region of the at least one outlet or the outlet duct.

11. The high lift system in accordance with claim 1 , wherein an activation device is provided for receipt of flight state data and generation of control signals, such that the flow control device can be activated and deactivated under particular flight conditions.

12. The high lift system in accordance with claim 11 , wherein the activation and deactivation occurs through adjustment of an opening state of an inlet opening and closing device of the at least one inlet and/or an opening state of an outlet opening and closing device of the at least one outlet.

13. The high lift system in accordance with claim 1 , wherein a distribution duct is provided between the at least one inlet duct and the at least one outlet duct.

14. The high lift system in accordance with claim 1 , wherein the at least one inlet duct is in fluid communication with a further aircraft system selected from an air conditioning system, a hydraulic system, or a pneumatic system.

15. A flow control device in accordance with claim 1 , wherein the ducts are modifiable at least partially in their axial projection by at least one of telescopic ducts and a bellows hose.

16. An aircraft having at least one high lift system with the features of claim 1 .

17. The high lift system in accordance with claim 4 , wherein the outlet opening and closing device is coupled kinematically with the adjusting device for a regulating flap of the high lift system, such that the opening status of the outlet opening and closing device is determined by the setting of the regulating flap.

18. The high lift system in accordance with claim 1 , wherein the at least one inlet comprises an inlet opening and closing device, and the at least one outlet comprises an outlet opening and closing device, such that one or both of the inlet opening and closing device and the outlet opening and closing device is coupled kinematically with the adjusting device for a regulating flap of the high lift system, such that the opening status of each respective opening and closing device is determined by the setting of the regulating flap.
