  • Airplane wing
    Patent number: 11427307
    Abstract: The invention relates to a wing with at least two winglets and a respective airplane. An upstream winglet broadens a region of inclined airflow and a more downstream winglet produces a thrust contribution therein.
    Type: Grant
    Filed: January 14, 2019
    Date of Patent: August 30, 2022
    Assignee: The Aircraft Performance Company GmbH
    Inventors: Hans-Jörg Petscher, Volker Kassera
  • Airplane wing
    Patent number: 11396368
    Abstract: The invention relates to a wing for an airplane having at least two winglets, wherein a local angle of attack at the upstream winglet shall be reduced by a passive elastic morphing in heavy load conditions and wherein stall shall occur for the downstream winglet, then. Both serves for limiting and reducing the forces and torques produced by the winglets.
    Type: Grant
    Filed: December 11, 2018

  • Airplane wing
    Patent number: 11312481
    Abstract: A wing for an airplane has an outer wing end and an inner side of the wing for mounting to the airplane. The outer wing has at least two winglets connected to the wing, including an upstream winglet preceding a downstream winglet in a flight direction of the wing. The first winglet and the second winglet are mutually inclined, as seen against the flight direction, by a relative dihedral angle.
