ワーステアリング装置。 In a traveling aircraft equipped with a steering hydraulic unit that supplies pressure oil pumped from a hydraulic pump to a hydraulic actuator for operating a steering wheel based on a steering direction and a steering angle of the steering wheel, the hydraulic pressure supply speed to the hydraulic pump is increased. On the other hand, in the hydraulic path from the hydraulic pump to the steering hydraulic unit,
Hydraulic path switching means is provided that can directly supply pressure oil supplied by the hydraulic pump to the hydraulic actuator for operating the steering wheels without passing through the steering hydraulic unit, and the speed increasing means and the hydraulic path switching means are connected to the steering wheel. Based on the fact that the turning angle of the wheel or the steering angle of the steering wheel exceeds a predetermined angle, the speed increasing command is linked to the speed increasing control means for outputting a hydraulic path switching command to the speed increasing means and the hydraulic path switching means, respectively. A power steering device for a traveling aircraft, which is characterized by:
