The aim of this work is to impose a disturbance on the velocity field already in the near field of the wake vortex system of a generic high-lift transport aircraft configuration by oscillating flaps. This should result in an excitation of long wave instabilities in the downstream development of the wake vortex system. For aerodynamic force measurements and particle image velocimetry measurements, experiments are carried out in the Göttingen-type low-speed wind tunnel A of the Chair of Aerodynami... »
