Keywords: lateral wing upper cover, stiffened panel, carbon fibre composite, finite element buckling analysis, optimisation

The present investigations are devoted to development of new optimal design concepts that exploit the full potential of advanced composite materials in aircraft lateral wing upper covers. Weight optimisation problems are solved for laminated composite panels with three types of stiffeners taking into account manufacturing, repairability and damage tolerance requirements.
