Abstract

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 Aerodynamics and Fluid Mechanics of the Technical University of Munich. Complimentary to the experimental data, unsteady Reynolds-averaged Navier–Stokes flow simulations are conducted. A baseline configuration with statically deflected flaps is compared to a configuration with actuated flaps. It can be shown experimentally as well as numerically that a significant disturbance can be imposed already in the near field of the wake vortex system by oscillating flaps.
