The embodiment of the invention discloses a yaw moment suppression method for a distributed electric propulsion aircraft. The yaw moment suppression method comprises the steps that system state parameters of a distributed electric propulsion system are obtained; aircraft characteristic parameters are obtained; according to the state parameters of the driving motor in the distributed electric propulsion system and the characteristic parameters of the airplane, yaw moment generated by the internal fault of the distributed electric propulsion system is obtained; obtaining a constraint condition of the distributed electric propulsion system, and calculating a target rotating speed of each driving motor in the distributed electric propulsion system according to the constraint condition; the target rotating speed of each driving motor is adjusted through a control unit in the distributed electric propulsion system, and yaw moment suppression or elimination caused by internal faults of the distributed electric propulsion system is achieved. According to the technical scheme provided by the embodiment of the invention, the problem that the flight attitude of an existing distributed electric propulsion aircraft is unstable due to the fact that the number of driving motors is large, and yawing torque is generated when the driving motors break down is solved.
