Two sets of driving devices, a worm and gear, a piston rod, an outer cylinder and a displacement sensor are matched, an undercarriage folding and unfolding actuating cylinder and a flaperon actuating cylinder are conveniently designed in an all-electric dual-redundancy mode, the system safety can be improved, light weight and low cost of the whole machine are achieved, the control precision is high, and later maintenance is convenient. The electric actuator cylinder adopts a dual-redundancy design, double motors work simultaneously under normal conditions, if one power supply, a control driver or a motor breaks down, the other power supply, the control driver and the motor can still work normally, actuation is completed, safe and reliable operation of the system is guaranteed, the displacement sensor and the two sets of driving devices are matched, the electric actuator cylinder adopts telex control, and operation is convenient. Electric execution is achieved, the control precision is high, the response speed is high, a BIT self-checking means can be conveniently adopted, system faults can be rapidly detected and positioned, special equipment is not needed in later maintenance, maintenance is convenient, and the cost is low.
