Patent number: 11939049Abstract: In an air mobility vehicle, an engine operates as required to provide mechanical driving force or electric energy. A battery is charged with the electric energy from the engine. Main rotors operate using the electric energy of the battery and electric power generated by the engine to perform takeoff, landing, and cruising. Auxiliary rotors are disposed at or adjacent to the center of gravity of a vehicle body and mechanically connected to the engine via a clutch. The auxiliary rotors perform the takeoff, the landing, or the cruising by receiving the mechanical driving force from the engine when the clutch is in an engaged position. A controller monitors the states of the battery and the main rotors and controls the operations of the engine and the clutch.Type: GrantFiled: September 19, 2022Date of Patent: March 26, 2024Assignees: Hyundai Motor Company, Kia CorporationInventors: Woo Suk Jung, Hee Kwang Lee, Hyun Seok Hong, Hyun Woo Jun
