A: Impact rudder means that the steering engine continues to rotate a certain Angle after turning to the command rudder Angle.
There are two kinds of steering transmission, electric and hydraulic:
1. The hydraulic steering transmission is composed of an actuator installed in the rudder nacelle, a hydraulic press installed in the cab and a pipe system connecting the two. Because of the non-yieldability of the oil pressure and the controllability of the flow direction, oil pressure and flow rate, the kinetic energy can be converted into hydraulic energy and then further converted into mechanical energy to complete the steering.
2. The handle steering and the attendant steering in the electric steering transmission device are called two independent steering systems of the device, whose function is that after the failure of one system, it can be replaced immediately to the other system to ensure navigation safety and do not deviate from the course.
