  • Bi-planer rotor blade
    Patent number: 10875639
    Abstract: A biplaner rotor blade has an upper airfoil section connected to a lower airfoil section such that the upper airfoil and lower airfoil are rotated in separate planes—an upper plane and a lower plane. The upper airfoil has a root end attached to a hub at an upper location of the hub and the lower airfoil has a root end attached to the hub at a lower location of the hub. The upper airfoil converges with the lower airfoil to form a blade tip end at the outermost portion of the blade, thus generating lift along two geometric planes.
    Type: Grant
    Filed: February 19, 2019
    Date of Patent: December 29, 2020
