The stiffening frames () of an aircraft fuselage () remain continuous while passing through an upper panel () of the wing box and extend over the ribs () situated in that box. The overall mechanical strength of the assembly is improved, despite the notches it is necessary to make in the panel ().

Connector for stiffening frames between an aircraft fuselage and a wing box

An aircraft structure includes a wing spar (), with orbital frames () arranged in transverse planes, right and left horizontal spars () connected to the wing spar () at the upper panel () of the spar respectively to the right and to the left of the spar, and for each right or left horizontal spar (), a triangular panel () that includes a wall (), a first edge arranged at the horizontal spar (), a second side arranged at the wing spar (), and a third side at which a first rectilinear oblique reinforcement () connecting the horizontal spar () and the wing spar () is provided, characterized in that the triangular panel () includes at least one second rectilinear oblique reinforcement () that connects the horizontal spar () and the wing spar ().
