Latest Patents

Ullman is credited with 1 patent: “Leading-Edge Ducted Fan Thrust Reduction System.” The invention describes powered electric lift augmentation systems attached to an airplane’s airfoil. Each system includes an electric ducted fan housed in a nacelle and may also include a pylon or slat. Pivoting drag elements, such as hinged plates, can be adjusted to create different levels of drag or stowed away. The elements may be connected to the airfoil’s leading edge, nacelle, pylon, or slat, and may include holes. The system is intended to increase drag while minimally reducing or potentially enhancing lift augmentation.
