Webbf• The ram type steering gear arrangement produces a considerably high value of torque for a given applied power. The hydraulic oil pressure varies from 100 bars to 175 bars depending on the size of the rudder and torque required. • ROTARY VANE TYPE STEERING GEAR • In rotary vane steering gear, there is a fixed housing in which two vanes rotate. WebbThe total rudder force CR is to be calculated according to S10.2.1.1. The pressure distribution over the rudder area, upon which the determination of rudder torque and rudder blade strength is to be based, is to be derived as follows: The rudder area may be divided into two rectangular or trapezoidal parts with areas A1 and
