Abstract

In this article the results of numerical calculations and experimental studies on wake vortex alleviation using Differential Flap Setting (DFS) and Oscillating Flap Setting (OFS) by means of a priciple model with rectangular wing as a vortex generator should be presented. The numerical part of the examination was made as an Euler-computation provided with flow solver TAU, the experiment was performed in water towing tank at DLR Göttingen. The comparison of different configurations according to flap setting, trigger frequency and influence of HTP vortex was conducted in this paper. Both numerical and experimental investigations have shown that it is possible to affect the wake vortex development using configurative methods on lift device. Further investigations have to be done to calculate the circulation and the rolling moment influence on following aircrafts.
