The PrandtlPlane (PrP) aircraft wing-box least-weight design is presented in thiswork. This design problem is formulated as a constrained non-linear programming prob-lem (CNLPP), by integrating static, buckling, fatigue and manufacturability requirements,under different loading conditions. The solution search is carried out by means of a suit-able multi-scale optimisation (MSO) approach. The physical responses involved into theCNLPP formulation are evaluated at the wing-box architecture level (macroscopic scale)and at the stiffened panel level (component scale), as well. The scale transition is ensuredby means of a suitable global-local (GL) modelling approach, while the CNLPP is solvedby means of an in-house genetic algorithm. The effectiveness of the proposed approach istested on the PrP wing-box structure, but the presented strategy can be easily extendedto conventional aircraft wings.< Réduire
