Ship Rudders: Parts, Function, Types with simple diagram
Rudder is a steel structure formed by two plates of 10-20mm thickness. Modern rudders are streamlined to reduce the water resistance. Stock: It turns the rudder, passing vertically upwards to the steering gear through a watertight rudder trunk.
Types of Rudders Used For Ships - Marine Insight
2024年2月11日 · To broadly categorize conventional rudders, there are two types of ship rudders: 1. Spade or Balanced Rudder. A spade rudder is basically a rudder plate that is fixed to the rudder stock only at the top of the rudder. In other words, the rudder stock (or the axis of the rudder) doesn’t run down along the span of the rudder.
