A multidisciplinary framework for the wing preliminary design is presented. Aerodynamicsis employed to optimise the wing planform shape. Then, topology optimisation is usedto optimise the internal wing structural layout for the corresponding planform. The wingof the Common Research Model is the baseline geometry. It is parameterised in order toinduce changes in the planform configuration. Two optimisation loops are included in thisframework. First, the nested SIMP-based topology optimisation. It is formulated in termsof compliance minimisation for a constrained volume fraction. The aerodynamic loads arecomputed only once for each new wing shape and the optimal material layout is identified.Following, the single-objective gradient-based optimisation which aims to maximise the aerodynamiceffciency and to minimise the structural mass associated to the optimised materialconfiguration. Results for the aerodynamic optimisation only come out with higher aspectratio and and increased effciency. When the e ect of mass is taken into account the aspectratio is smaller and the optimised planform becomes similar to the reference case.
