A DOUBLE-CURVED COVER FOR COVERING A GAP BETWEEN TWO STRUCTURAL PORTIONS OF AN AIRCRAFT

摘要

A cover for covering a gap between a first structural portion and a second structural portion of an aerial vehicle. A first attachment section is attachable to the first structural portion. A second flexible section covers the gap. The second flexible section includes an abutment portion for abutting against the second structural portion in an operating state. The abutment portion in an unloaded state forms an undulating shape having troughs and crests extending along a curved plane. The curvature of the curved plane essentially corresponds with the curvature of the surface of the second structural portion. The troughs are provided for engagement with the surface in the operating state such that the troughs tend to be flatten out and propagate over the surface pressing down neighboring crests towards the surface for providing a close fit between the cover and the second structural portion.
