The project's aim is to use novel Mixed-Integer Conic Optimization (MICO) techniques to design aircraft wing structures that take full advantage of new composite materials and manufacturing restrictions. Considering the freedom provided by these design options is key to develop cutting-edge wing designs. However, obtaining (guaranteed) near-optimal solutions for the resulting large-scale structural design problem is very challenging for current solution approaches. The MICO solution approach allows to capture this complexity and obtain near-optimal solutions. In particular, as a result of this project, novel results have been obtained and published regarding the solution of discrete truss topology and ply-angle problems.
