High lift system for an aircraft

摘要

A high lift system with a main wing and control flaps, wherein the respective guiding device are 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 two inlet ducts running along the main wing chordwise direction with in each case at least one inlet, which device is located on or underneath the lower surface of the high lift system, wherein at least one outlet duct for air is furthermore provided, which is connected with the inlet ducts in a fluid-communicating manner, and has at least one outlet, which is located on the upper surface of at least one regulating flap and/or with respect to the main wing chordwise direction in the rear third of the main wing of the high lift system.

主权项

1. A high lift system comprising a main wing, control flaps, and guiding devices for the positioning of the control flaps, wherein the guiding devices are at least partially provided with a fairing, the high lift system further comprising:
a flow control device for purposes of influencing the flow around the main wing and the control flaps, with at least one inlet duct running along the main wing chordwise direction each with at least one inlet, which is located on or underneath a lower surface of the main wing, and at least one outlet duct, which is connected with the at least one inlet duct in a fluid-communicating manner, and has at least one outlet so that fluid which is streaming into the inlet duct can be discharged through the outlet, wherein the outlet is located on at least one of an upper surface of the at least one control flap and on an upper side of the main wing, on the main wing in the rear third of the length of the main wing with respect to the main wing chordwise direction; wherein the flow control device is arranged at least partially within the fairing, and the inlet of the at least one inlet duct is facing in opposition to the main wing chordwise direction; and wherein at least one inlet per inlet duct is arranged in a range starting from the front of the fairing with respect to the main wing chordwise direction and extending to over one third in the direction of the main wing chordwise direction.
