Abstract: A flight control device performs a flight control process for causing an eVTOL to fly. In a step of the flight control process, the flight control device determines whether the eVTOL is capable of maintaining a stable attitude. In the step, it is determined whether the eVTOL is capable of maintaining the stable attitude even if driving of an abnormal motor is stopped. In the step, it is determined whether the eVTOL is capable of maintaining the stable attitude even if the abnormal motor continues driving. When it is determined that the eVTOL is capable of maintaining the stable attitude, the flight control device performs output adjustment of at least one of a normal motor and the abnormal motor to maintain the eVTOL at the stable attitude.

Abstract: A lock device can be shifted between a locked state and an unlocked state. The lock device includes a lock pin, a solenoid, and a pressing unit. The lock pin is movable between a locked position where a propeller is locked and an unlocked position where the propeller is not locked. The pressing unit presses the lock pin to the locked position by a mechanical pressing force. The solenoid includes a solenoid coil and a plunger. When the solenoid coil is energized, the plunger moves the lock pin to the unlocked position against the mechanical pressing force.

Abstract: The disclosure relates to a technique for controlling an electric flight vehicle having a rotary wing driven by electric power of a battery. In the technique, a temperature of the battery is acquired as a battery temperature. Restriction is placed on take-off of the electric flight vehicle when the battery temperature is lower than a take-off permitting temperature that is a temperature for permitting take-off of the electric flight vehicle. The restriction placed on take-off of the electric flight vehicle may be terminated when the battery temperature exceeds a restriction terminating temperature and the battery temperature raising processing is performed. The restriction terminating temperature is higher than the take-off permitting temperature.

Abstract: In a control device including a control unit that controls an EPU for powering a rotor included in an electric aircraft, the EPU includes a motor, an inverter, a control circuit, and a first sensor that detects an operation-related value. If there is no a sudden change in the operation-related value detected by the first sensor, the control unit controls the EPU based on the operation-related value detected by the first sensor. When the sudden change occurs, the control unit stops using the operation-related value detected by the first sensor to control the EPU. After the occurrence of the sudden change, when the sudden change ends before a predetermined period elapses, the control unit resumes using the operation-related value detected by the first sensor to control the EPU, and when the sudden change has not ended, the control unit continues the stoppage.

Abstract: An EPU includes a first DS and a second DS. The first DS includes a first motor and a first inverter control unit. The second DS includes a second motor and a second inverter control unit. The first motor and the second motor are connected to a propeller via an EPU shaft. The EPU shaft drives and rotates a propeller according to outputs of the motor. The first inverter control unit controls the first motor so that the output of the first motor and the output of the second motor become a same. The second inverter control unit controls the second motor so that the output of the first motor and the output of the second motor become same as each other.
