  • Publication number: 20230002031
    Abstract: A wing (5) including a fixed wing (7), a high-lift device (15) and a hold-down arrangement arranged (27) between two supports (23, 25) of the high lift device (15) having a first hold-down element (29) attached to the high-lift device (15) and a second hold-down element (31) attached to the fixed wing (7). The first hold-down element (29) contacts the second hold-down element (31) when the high-lift device (15) is in a retracted position in which it prevents a trailing edge (22) of the high-lift device (15) from detaching from an upper surface (19) of the fixed wing (7) when the fixed wing (7) deforms in the spanwise direction. One of the hold-down elements (29, 31) is a load-limited hold-down element (32) which transition from a first stable state to a second state when the load acting on the hold-down arrangement (27) exceeds an operational threshold.

  • Publication number: 20230002032
    Abstract: A wing (5) for an aircraft (1) including a fixed wing (7), a high-lift device (15) and a hold-down arrangement (27) between two supports (23, 25) and having a first hold-down element (29) attached to the high-lift device (15) and a second hold-down element (31) attached to the fixed wing (7). The first hold-down element (29) contacts the second hold-down element (31) when the high-lift device (15) is in a retracted position to prevent a trailing edge (22) of the high-lift device (15) from detaching from an upper surface (19) of the fixed wing (7). One of the hold-down elements (29, 31) is a load-limited hold-down element (32) which is destroyed when loads transmitted through the hold down elements (29, 31) exceed a threshold. Once destroyed, the trailing edge (22) of the high-lift device (15) is not prevented from detaching from the upper surface (19).

  • Publication number: 20220411044
    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 bends in the spanwise direction. One of the hold-down elements is a load-limited hold-down element which comprises a biasing means. When the load transmitted through the hold-down arrangement exceeds an operational threshold, elastic deformation of the biasing element results in the hold-down arrangement no longer preventing the trailing edge high-lift device from detaching from the upper surface of the fixed wing.

  • Publication number: 20220219825
    Abstract: A flow body for an aircraft with an integrated de-icing system. The flow body includes a front skin, an internal structural component, a lever having first and second ends, with an attachment point in-between, and an actuator. The actuator is spaced inside the front skin. The lever extends from the actuator to a front skin inner surface, the first end coupling with the front skin, and the second end coupling with the actuator. The attachment point is swivably supported on the internal structural component. The attachment joint is closer to the first end than the second end. The lever and the actuator apply an impulsive force in a transverse direction to the lever, such that the lever rotates around the attachment point, and such the first end urges the front skin to locally elastically deform for removing ice accretion from an outer side of the front skin.
