The panel comprises a surface sheet to insert one or more core portions facing in an axial direction and an adjacent integrated sandwich panel. The box structure also comprises several spars. Each spar includes a web and web attachments, and the length is in the axial direction. The spars are connected to the integrated sandwich panel equipped with a web attachment placed on a concentrated pack. The surface sheet is designed to convey twisting and pressure loads and non-significant axial loads at the front end. The concentrated pack is designed to convey all important box foldings from axial direction extension and pressure loads. |
