Patent number: 11866150Abstract: A propeller safety device is provided. The propeller safety device is configured to insert a moving part of a propeller into a fixed part during a crash of an air mobility to allow a reduction in the total length of the propeller, thereby preventing the propeller from hitting the ground. Accordingly, a secondary accident due to fragments formed when the rotating propeller hits the ground is prevented.Type: GrantFiled: November 22, 2021Date of Patent: January 9, 2024Assignees: Hyundai Motor Company, Kia CorporationInventors: Ji Woo Yoo, Youn Sic Nam, Keon Woo Kim, Kwan Ho Moh, Young Heon Kim

Patent number: 11787530Abstract: 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: GrantFiled: November 22, 2021Date of Patent: October 17, 2023Assignees: Hyundai Motor Company, Kia CorporationInventors: Youn Sic Nam, Ui Jin Jung, Young Tae Kim, Young Heon Kim
