Marine Rudder Blade
The rudder blade is the main part of the rudder that generates rudder pressure.
In order to ensure the strength and linear shape of the rudder blade, the horizontal partition and vertical partition are used to form the skeleton according to the linear shape, and the two streamlined shell plates are directly welded outside the skeleton.
The rudder blade is typically located underwater at the stern of the vessel. When the helm is turned, the rudder pivots, altering the flow of water around the boat, causing it to turn left or right.
Overview
The rudder blade bottom leading edge should be rounded to avoid local cavitation and erosion. The contact area of the tapered connection between the blade and the tiller should be verified by drawing test (minimum 70%). The inner surface should be covered with a corrosion resistant coating. Rudder blade drainage should be provided after pressure testing or possible leakage.
In order to facilitate the installation and disassembly of the rudder blade, a rope hole composed of steel pipe is opened on the rudder blade, or a groove is opened on the tail end of the rudder blade.
