| 8096513 | Aerodynamic flap of an aircraft having a device which influences the flap vortex A high-lift flap of an aircraft is provided having a device for influencing the flap vortex as well as a device for influencing the flap vortex at the lateral edge of the aerodynamic high-lift flap, which can be achieved effectively and at low cost. ... | 01/17/2012 |
| 7661629 | Systems and methods for destabilizing an airfoil vortex Apparatuses and methods for the controlled trailing wake flows. An apparatus in accordance with one embodiment is directed to an aircraft system that includes an airfoil having first and second oppositely facing flow surfaces and a tip. The system can further includ... | 02/16/2010 |
| 7637462 | Surface flow diverting and static charging ducted pores on wing or blade tip to reduce wake and BVI noise Air pressure distribution for airfoil lower and upper surfaces is utilized to divert airflow using ducts formed in space-curve shapes placed inside the airfoil volume, through span-wise located inlets from high pressure areas on the airfoil lower surface near the le... | 12/29/2009 |
| 7275722 | Wing tip device An aircraft comprises a wing tip device, for example a winglet, a raked-tip device, a wing tip fence or a planar wing extension, mounted in the region of the tip of a wing on the aircraft. The wing tip device is rotatably moveable between a first position and a seco... | 10/02/2007 |
| 4705240 | Passive vortex lift control A method of applying and controlling vortex lift to a unique high-lift airfoil (29) is described wherein the planform of the airfoil (29) comprises a swept-forward outer panel (31) and a swept-aft or unswept inboard panel (33). A leading edge vortex (37) ... | 11/10/1987 |
| 4697769 | Method and apparatus for controlling bound vortices in the vicinity of lifting surfaces The lift generated by delta wings is due primarily to large vortices associated with the flow separation near the leading edge. The invention includes a perturbation device to control the separation shedding of those vortices and manipulate their frequenc... | 10/06/1987 |
| 4477042 | Vortex alleviating wing tip A wing tip is contoured and shaped to bring about a controlled mergence of fluid flows across the upper and lower wing surfaces and alleviation of the resulting vortex when the wing is producing lift or thrust. Control through geometry of the wing tip can... | 10/16/1984 |
| 4362280 | Method and apparatus for reducing destructive effects of tornados A method of reducing the destructive effects of a tornado, which has a rotary motion about a center and has at least one clear air inflow region at its periphery, comprises towing through the inflow region one or more fluid dynamic converters which impart... | 12/07/1982 |
| 4108403 | Vortex reducing wing tip An airfoil tip is constructed to droop downward and extend aft of the trailing edge of the air foil structure and to include air foil configuration both chordwise and spanwise with camber in both the chordwise and spanwise directions and further including... | 08/22/1978 |
| 3934844 | Free vortex aircraft An aircraft has air pumping devices which retain, concentrate and augment vorticity shed from a surface of the moving aircraft in such a way as to allow the formation of a lift producing and drag reducing free vortex which travels along with the aircraft ... | 01/27/1976 |
