Abstract: A vertical landing is performed by an electric vertical take-off and landing (eVTOL) vehicle above a charger where the eVTOL vehicle includes a rotor that is configured to rotate during an occupant change state to keep the eVTOL vehicle stationary during the occupant change state. A vertically-oriented male charging port that is part of the eVTOL vehicle and a female charging port that is part of the charger are detachably coupled and a battery in the eVTOL vehicle is charged using the charger while the vertically-oriented male charging port and the female charging port are detachably coupled.

Abstract: A vertical takeoff and landing (VTOL) vehicle that includes a flight controller and a rotor. During a vertical landing state, during which the VTOL vehicle is performing a vertical landing, the flight controller decides whether to switch from the vertical landing state to a self adjusting state and in the event it is decided to do so, the flight controller switches from the vertical landing state to the self adjusting state. During the self adjusting state, the flight controller generates a control signal for a rotor where the control signal causes: (1) the rotor to rotate during the self adjusting state and (2) the VTOL vehicle to stay in place during the self adjusting state, such that an occupant is able to enter or exit the VTOL vehicle during the self adjusting state.

Abstract: An electric vertical take-off and landing (eVTOL) vehicle is positioned to be in a charging position on the ground, wherein the eVTOL vehicle is capable of performing vertical take-offs and landings. The battery is charged while in the charging position on the ground using a wind turbine that includes the rotor.

Abstract: A vertical landing of an aircraft is performed using the first battery where the aircraft is unoccupied when the vertical landing is performed, the unoccupied aircraft includes the first battery, and the unoccupied aircraft excludes a second, removable battery. In response to detecting that the second, removable battery is detachably coupled to the aircraft, a power source for the aircraft is switched from the first battery to the second, removable battery. After switching the switch power source, a vertical takeoff of the aircraft is performed using the second, removable battery, wherein the aircraft is occupied when the vertical takeoff is performed.

Abstract: A first and a second aircraft are detachably coupled where the first aircraft is configured to perform a vertical landing using a first battery while the first aircraft is unoccupied and the unoccupied first aircraft includes the first battery. In response to detecting a second, removable battery being detachably coupled to the first aircraft, a power source for the first aircraft is switched from the first battery to the second, removable battery. After the switch, the first aircraft takes off vertically using the second, removable battery while occupied. The detachably coupled first aircraft and second aircraft are flown using the second aircraft (the power to keep the detachably coupled first aircraft and second aircraft airborne comes exclusively from the second aircraft and not the first aircraft).

Abstract: A vertical landing is performed by an electric vertical take-off and landing (eVTOL) vehicle above a charger where the eVTOL vehicle includes a rotor that is configured to rotate during an occupant change state to keep the eVTOL vehicle stationary during the occupant change state. The eVTOL communicates with an area controller to receive an assignment of the charger from the plurality of chargers in the area based at least on part on an occupancy status of the charger. The charger is located in an area that includes a plurality of chargers. A male charging port that is part of the eVTOL vehicle and a female charging port that is part of the charger are detachably coupled and a battery in the eVTOL vehicle is charged using the charger while the male charging port and the female charging port are detachably coupled.

Abstract: During a vertical landing state, it is decided whether to switch from the vertical landing state to a self adjusting state. The VTOL vehicle includes the flight controller, the rotor, and a fuselage where the rotor is coupled to the fuselage via a vertical connector. If it is so decided, there is a switch from the vertical landing state to the self adjusting state. During the self adjusting state, a control signal for a rotor is generated where the control signal causes: (1) the rotor to rotate during the self adjusting state and (2) the VTOL vehicle to remain in a fixed position during the self adjusting state, in response to the control signal, and independent of docking infrastructure. During a rotors off state, a rotor off control signal is generated for the rotor that causes the rotor to turn off.

Abstract: A first propeller has a shorter blade length and a lower inertia than a second propeller. An electromagnetic field emitter is coupled to one of the first propeller or the second propeller and an electromagnetic field receptor is coupled to the other one that is not coupled to the electromagnetic field emitter. The electromagnetic field emitter emits an electromagnetic field. In response to the electromagnetic field: the electromagnetic field receptor and its coupled propeller rotate in a first rotational direction; and the electromagnetic field emitter and its coupled propeller rotate in a second and counter-rotational direction. In response to a second electromagnetic field associated with increasing torque: the first propeller increases and subsequently decreases its rotational speed; and the second propeller increases its rotational speed at a slower rate than the increase in the rotational speed of the first propeller.
