  • Patent number: 10220953
    Abstract: In an aerial vehicle, a malfunction determiner determines whether there is a malfunction in one of thrusters of the aerial vehicle. A flight controller activates the thrusters, and controls the output of each of the thrusters. The flight controller deactivates, when it is determined that there is a malfunction in one of the thrusters as a malfunctioned thruster, the malfunctioned thruster. The flight controller deactivates a selected thruster in the thrusters; the selected thruster being paired to the malfunctioned thruster, and controls the active thrusters except for the deactivated thrusters in all the thrusters to make the flight attitude of the aerial vehicle stable. The flight controller controls the active thrusters to cause the aerial vehicle to land while maintaining the flight attitude of the aerial vehicle being stable.
