    • A flow body for an aircraft with an integrated de-icing system is proposed. The flow body comprises a front skin, at least one internal structural component arranged inside the front skin, at least one lever having a first end, a second end and an attachment point between the first end and the second end, and at least one actuator for applying an impulsive force. The actuator is arranged inside the front skin at a distance thereto, wherein the lever extends from the actuator to an inner surface of the front skin, such that the first end is coupled with the front skin and such that the second end is coupled with the actuator, wherein the attachment point is swivably supported on the internal structural component, wherein a distance between the second end and the attachment joint is greater than the distance between the first end and the attachment joint, and wherein the lever and the actuator are designed for applying 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.

    • An airfoil device (10) for attachment to the wing (14) of an aircraft (12). The airfoil device (10) has a chamber (30) which is inflatable to provide a lift-enhancing airfoil geometry to the wing (14) and other chambers (32) which are inflatable to provide deicing forces to remove ice accumulation on the wing (14). When installed on the wing (14), the airfoil device (10) closely conforms to the wing's airfoil geometry (e.g., low camber, sharp leading edge) when the lift-enhancing chamber (30) and the deicing chambers (32) are in a deflated condition. The lift-enhancing chamber (30) can be inflated during take-off and landing to provide a high chamber and less sharp airfoil geometry. If ice accumulates on the wing (14) during high speed flight, the deicing chambers (32) can be repeatedly inflated/deflated for ice removal purposes.
