Marine Active Rudder
The active rudder is equipped with a small electric propeller or a small conduit propeller at the rear of the rudder blade. It is a kind of rudder for steering and pushing the boat slowly. A small steering propeller or a swivel conduit is provided in the middle of the trailing edge of the streamline rudder, which is connected with the main propeller by a universal coupling. More recent active rudders are driven by small electric motors mounted inside a closed, streamlined cladding plate.
Overview
The effect of the ordinary rudder decreases as the speed decreases. In order to improve the effect of the rudder equipment at low speed, the active rudder is used. An active rudder can reduce drag and optimize water flow around the rudder and hull, resulting in lower fuel consumption. By dynamically optimizing the rudder angle, active rudders can enhance a vessel's ability to turn more sharply or maintain a steady course in challenging conditions.
Applications of Marine Active Rudder:
The marine active rudder is popular for ships of high operating performance, special ships, small vessels with high slewing requirements and frequent departures from wharves such as patrol boats, pilot boats, ferries, and so on.
It is also used in some scientific research ships, because its propeller on the rudder can also be used as a micro-speed thruster.
It is suitable for pushing ships, tugboats, measuring ships, cable laying ships, whaling ships and other vessels with high maneuverability requirements. The maximum rudder angle of active rudder reaches70°~ 90°, so the transship torque generated by active rudder is much larger than that generated by ordinary rudder, so that the maneuverability is improved in low speed, very low speed of stop main engine, inertial dripping, reversing and wind and waves.
