The structure has an exterior skin (1) and an inner liner (2) connected to the periphery of a bonnet. The inner liner contacts with the interior of the periphery of the exterior skin by a cylindrical bulged shape (3). The bulged shape extends along a path following a continuous line (L) that is closed around a central zone of the liner and is directed towards an interior surface of the skin from the inner liner. |
