A mult-rib box-shaped aeronautical structure comprising upper and lower skins (19, 21) stiffened by span wise stringers (25, 25', 25"), span wise front and rear spars (11, 13) and chord wise ribs (27, 27', 27"), where at least one panel (31, 33) of any of said skins (19, 21) is non delimited by said ribs (27, 27', 27") and said stringers (25, 25', 25") and comprise an stiffening element (41, 43) arranged as a panel breaker to avoiding the need of increasing the panel thickness to withstand buckling loads. |
