Abstract:
1. An aircraft structure comprising a first stiffened panel, said first panel comprising a skin and at least one stiffener, the stiffener of the first panel comprising at least two sole plates attached to one side of the skin of said panel, referred to as the internal side, the stiffener of the first panel extending according to a longitudinal axis of the first panel, the stiffener of the first panel being interrupted near to one end of said first panel, at least one second stiffened panel, said second panel comprising a skin and at least one stiffener, the stiffener of the second panel comprising at least two sole plates attached to one side of the skin of said panel, referred to as the internal side, the stiffener of the second panel extending according to a longitudinal axis of the second panel, the stiffener of the second panel being interrupted near to one end of said second panel, the first panel and the second panel are assembled in such a way that their ends are placed close to each other and form a line of interface, the stiffener of the first panel is opposite the stiffener of the second panel, said stiffeners being substantially aligned according to a direction substantially parallel to the longitudinal axes of the panels, a shroud partially covering the first and second panels, said shroud being on the one hand assembled on the first panel and on the other hand assembled on the second panel, said aircraft structure being wherein: the structure partially covers at least two sole plates of the stiffener of the first panel and at least two sole plates of the stiffener of the second panel, said structure comprises at least one doubler, said doubler extending along the panels over a distance, according to the longitudinal axes of said panels, at least equal to the distance covered by the shroud according to these longitudinal axes, on either side of the line of interface of said panels, the doubler associated to the sole plates of the stiffeners forms a continuous and regular support surface for the shroud.
