Description
Technical Field

[0002] The rudder blade is the part of the rudder that enters the water and is the main body that generates the rudder force. Its main function is to control the direction of the ship's navigation. When the rudder blade is deflected, it will change the direction of the water flow, thereby generating a water force that causes the ship to turn.
[0003] When it is necessary to control the sailing direction of the concrete mixing transport ship, the direction of the concrete mixing transport ship is changed by controlling the rudder blade to deflect. The rudder pressure is perpendicular to the rudder blade and acts on the pressure center of the rudder blade. This force will point to the back side of the rudder blade, generating a torque to turn the ship. The magnitude of the torque is related to the size of the rudder blade. During the use of the concrete mixing transport ship, the weight of the concrete loaded on the ship is different, the overall weight of the ship is different, and the rudder blade size remains unchanged, which will affect the sensitivity of the steering and is not conducive to controlling the concrete mixing transport ship to make changes.
