Abstract
Official abstract text for this publication.
A system for reducing drag on an aircraft includes an ambient air inlet positioned in or near a wingtip fence and or winglet of the aircraft and an air pressurization device, such as an air compressor, coupled to the ambient air inlet. The air pressurization device has an inlet oriented toward the ambient air inlet. The air pressurization device has an outlet oriented toward an interior of the aircraft.
First claim
Opening claim text (preview).
I claim: 1. A system for reducing drag on an aircraft having a wing and, at a distal end thereof, a wingtip fence, wherein the wingtip fence has a high pressure side and an opposite low pressure side, wherein the high pressure side is at an underside of the wing, the system comprising: an ambient air inlet positioned on only the high pressure side of the wingtip fence; wherein the air inlet is positioned only at a juncture of the wing and the wingtip fence; and an air pressurization device coupled to the ambient air inlet; wherein the air pressurization device has an inlet oriented toward the ambient air inlet; and wherein the air pressurization device has an outlet oriented toward an interior of the aircraft. 2. The system of claim 1 wherein the air pressurization device is positioned in the wing of the aircraft. 3. The system of claim 1 wherein the air pressurization device is an air compressor. 4. The system of claim 3 wherein the air compressor is electrically powered.
