N2 - Design of primary structural parts for aerospace applications is a challenging process. When it comes to multi-part units such as a wingbox, it becomes even more demanding due to added complexity arising from assembly and integration processes, together with their associated considerations and limitations. In this work, a three-meter long, variable stiffness, three-bay, thermoplastic composite wingbox structure with integrated stiffeners is designed for prescribed buckling and post-buckling performances. The design considers prescribed load cases for a real testing scenario. Stiffeners are integrated into the top and bottom panels of the wingbox and two spars are blended in the structure, making it a single piece with no fasteners or joints. A manhole is also introduced into the bottom skin for access purposes, around which the tows are steered to reduce strain concentrations and weight. Tow steering is also investigated for improved load carrying capacity of skin bays subjected to compression-induced buckling. Finally, the design solutions are verified by performing virtual testing via finite element analysis.
