What is rotary vane steering gear?

Rotary vane steering gear is a type of hydraulic steering system commonly used in ships and large marine vessels. It operates using a series of vanes mounted on a rotating cylinder, which are actuated by hydraulic pressure to direct the flow of fluid and adjust the position of the rudder. This mechanism allows for precise control of the vessel's direction, making it suitable for navigating through challenging marine environments. The efficiency and responsiveness of rotary vane steering gear contribute to enhanced maneuverability at various speeds.
