Aircraft assembly comprising a self-stiffened panel comprising a portion of increasing height by means of which the panel is fixed to a structural element

An aircraft assembly comprising:

• a structural element, and
• a self-stiffened panel comprising a skin and a stiffening structure incorporated into the skin and formed of a network of ribs,
• the structural element comprising at least one end formed of a first closure rib,
• the stiffening structure of the self-stiffened panel comprising at least one end formed of a second closure rib,
• the stiffening structure of the self-stiffened panel comprising a portion of which the height increases progressively as far as the second closure rib,
• the structural element being fixed to the self-stiffened panel by means of first through-fixing elements which fix the first closure rib to the second closure rib, and
• the structural element comprising a sole having a first face on a side of the sole where the first closure rib is formed, and a second face on an opposite side, and the sole has, on the second face, an insert delimiting a space at an end part of the sole, into which extends an end part of the skin of the self-stiffened panel.
