Claim:
1. A wingtip extension for a wing of an aircraft for reducing of wake vortices, comprising: a leading edge at least partially being substantially straight; and a trailing edge configured to be affixable to a connection region of the wing; wherein a straight section of the leading edge comprises a leading-edge sweep angle exceeding the leading-edge sweep angle of the wing; wherein a local depth of the wingtip extension corresponds to a local depth of the wing in the connection region; wherein a local depth of the wingtip extension gradually decreases between a connecting region for connection to the wing and the opposite end of the wingtip extension wherein the wingtip is configured such that a wingtip vortex arising from the wingtip is influenced by a bursting vortex core such that the wingtip vortex starts to decay; and wherein a cross-sectional profile of the wingtip extension is substantially flat or at least at the leading edge is tapered to a point.
