摘要：
PROBLEM TO BE SOLVED: To provide a hydraulic system for an aircraft actuator which drives an actuator even when a loss or reduction in the function of an aircraft hydraulic power source occurs, and which suppresses an increase in the overall temperature of the system and in the temperature of an oil used.SOLUTION: The hydraulic system includes: an electric motor 19, which drives a variable capacity backup hydraulic pump 18 that can supply pressure oil to an actuator 14 when a loss or reduction occurs in the function of an aircraft central hydraulic power source 104; a power source unit 20 which rectifies electric power supplied from a variable frequency supply 108; and a driver 21 which supplies the electric power from the power source unit 20 and drives the electric motor 19 so as to rotate the pump 18 at a predetermined constant rotational speed. The constant rotational speed is set, based on the change in the efficiency of each of the pump 18, the electric motor 19, and the driver 21 with respect to the rotational speed of the pump so as to maximize the overall efficiency obtained as a product of these efficiencies.
