Visualisation of a wake vortex

Visualisation of a wake vortex generated by DLR's Advanced Technologies Testing Aircraft System (ATTAS) at the Braunschweig research airfield. Wake vortices are air turbulence produced by the wings, particularly during low-speed flight such as that during take-off and landing.

The aim of the experiments is to reduce the possible separation distance between aircraft coming in to land or taking off behind one other, by means of a more accurate computation of the evolution and decay of wake vortices.
