Abstract [en]

An approach to minimize the induced drag of an aeroelastic configuration by means of multiple leading and trailing edge control surfaces is investigated. A computational boundary-element model is constructed and flap settings which reduce the induced drag predicted by the model are found by means of numerical optimization. Further, experiments with an elastic wind tunnel model are performed, showing both the potential for drag reduction and weaknesses of the simulation method employed.
