Keywords: Wake Vortex, Large Transport Aircraft, Passive Influencing, Wind Tunnel, Experiment

The flow field behind a Very Large Transport Aircraft is investigated at several cross-flow planes. The amplification of instability mechanisms using an active rudder on a large winglet will be discussed. Results will be shown for the baseline and cases of passive and active rudder deflections using hot-wire anemometry.
