Abstract

A wing for an aircraft is disclosed including a fixed wing, a high-lift device and a hold-down arrangement arranged between two supports of the high lift device having a first hold-down element attached to the high-lift device and a second hold-down element attached to the fixed wing. The first hold-down element contacts the second hold-down element when the high-lift device is in a retracted position in which it prevents a trailing edge of the high-lift device from detaching from an upper surface of the fixed wing when the fixed wing deforms in the spanwise direction. One of the hold-down elements is a load-limited hold-down element which comprises a hydraulic element that is configured to allow the high-lift device to move away from the fixed wing when a load acting through the hold-down arrangement exceeds an operational threshold.
