[edit] Opis

The photo shows wingtip vortices generated by a Lockheed L-1011. These are visualized by smoke. The corkscrew character is nicely illustrated here. On the full-size version, the vortex cores are clearly visible. This experiment is part of NASA Dryden's trailing vortex work. The reasons for looking at trailing vortices include the fact that they are the source of induced drag and the possibility that they can be a danger to small aircraft which follow the larger aircraft. The latter can be of interest both in the air or during landing or takeoff.
