Visualisation of a wake vortex

Visualisation of a wake vortex
Visualisation of a wake vortex generated by ATTAS at the research airfield. Wake vortices are air turbulences produced by the wings, particularly during low-speed flying 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.
