  • Fail safety apparatus of air mobility
    Patent number: 11787530
    Abstract: A fail safety apparatus of the air mobility is provided. Locations of propeller modules are adjusted by rotation parts and length adjustment units to evenly distribute thrust of the re-located propeller modules so that the attitude of the air mobility is stabilized. In particular, when one propeller module among a plurality of propeller modules fails, the attitude of the air mobility is normalized by adjusting a location of the failed propeller module and locations of remaining normal propeller modules so that flight safety of the air mobility is secured.
    Type: Grant
    Filed: November 22, 2021
    Date of Patent: October 17, 2023
    Assignees: Hyundai Motor Company, Kia Corporation
    Inventors: Youn Sic Nam, Ui Jin Jung, Young Tae Kim, Young Heon Kim
