Abstract
Trailing vortices generated by large aircraft pose a
serious hazard to other planes. Numerous studies have been
carried out to destroy them either before and/or after their
formation. The present investigation is a survey and critical
assessment of all the known active/passive devices and
wingtip modifications proposed to achieve vortex attenuation.
It is concluded that some devices, such as the wing
tip sails, have promise in affecting the vortex roll-up in
the vicinity of the aircraft. However, more data and analysis
on this and other devices are needed before they can be
incorporated into existing aircraft or future designs.
