초록

The present invention is a wingtip vortex device for induced drag reduction and vortex cancellation. The wingtip vortex device is an aerodynamic drag reduction system installed at the wingtips of an aircraft. The wingtip vortex device comprises an impeller located ahead of the wingtip chord, a wind turbine device located behind the wingtip chord, and an intermediate gear device for coupling the impeller with the wind turbine and/or for generating power. Thus, the wingtip vortex device is self-contained as the impeller is powered by the vortex-driven turb...

청구항

[ What is claimed is:] [1.] An aerodynamic drag reduction and vortex cancellation system for a wingtip of a wing of an aircraft, the wingtip having a wingtip chord, said system comprising:an impeller located at a front position of the wingtip chord;a wind turbine device located at a back position of the wingtip chord in close proximity to high-velocity vortex forces created by the wingtip for rotating said wind turbine device in a similar rotational direction to that of the vortex forces; andan intermediate gear device for coupling said impeller to said ...
