Description

A ship's rudder structure

technical field

The utility model belongs to the technical field of ship equipment and relates to a ship rudder structure.

Background technique

Ship is the general term for all kinds of ships. It is a means of transportation that can sail or berth in waters for transportation or operation. It has different technical performance, equipment and structure types according to different use requirements. Civil ships are generally called ships, military ships are called ships, and small ships are called boats or boats. The shape of the propulsion system is generally a streamlined envelope that is conducive to overcoming fluid resistance. Ships need to control the direction through rudder blades. Rudder blades are the body that generates the rudder force. They are made of wood or steel. Now, except for wooden sailboats, they are all made of steel, and most of them are welded into hollow airfoils. The panel of the rudder blade is called the rudder plate, and the rudder blade of the flat rudder is also the rudder plate. The rudder can change the course of the ship by changing the direction of the rudder blades when the ship is sailing. The higher the speed of the ship, the more sensitive the adjustment. When the ship is stationary, the rudder cannot change the reverse direction of the ship, and usually only depends on the push of the auxiliary ship.
