rudder, an externally mounted component of a boat or ship’s steering system that is typically attached at the stern. The most typical design consists of a metal or wood surface that is virtually flat and has a hinge connecting its forward edge to the sternpost.
It works on the theory of different water pressures.marine. a tool for controlling and directing a ship. Hydrofoils that pivot on a vertical axis are known as rudders.A principal control surface for steering a ship, boat, submarine, hovercraft, aircraft, or other moving object through a fluid medium (often air or water) is a rudder.
The Global Marine Rudder system Market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
Launch of a New Rudder System by Kongsberg Maritime The steering forces from the rudder are transferred through the headbox and steering gear deck into the hull structure by a unique Direct Trunk Support system for rudders introduced by Kongsberg Maritime. Weight savings from this are expected to result in improved manoeuvrability and propulsion, which will ultimately save fuel and lower emissions.
The DTS rudder, according to Kongsberg, has no maximum size and is suitable for ships of any size, from fishing boats to superyachts, and in any industry. The radial forces and bending moment transmitted from the rudder blade to the steering gear are eliminated.
An expanded pipe built into the rudder trunk allows for this. This indicates that the DTS system’s rudder stock (torque shaft) exclusively transmits torque and axial loads.The new DTS system offers some of its most significant advantages throughout the ship’s design phase.
A lower-positioned steering gear deck is possible thanks to the increased weight distribution, which provides the ship designer more freedom in the aft ship design. This increases any vessel’s capacity for storage. Since the DTS system just transfers torque load, ship owners also have the option of selecting smaller steering gear.
Because heavy cast parts are no longer required thanks to the DTS technology, larger rudders are more competitive thanks to weight reductions and shortened lead times. The split rudder design also lightens the weight of individual parts and makes handling them safer during production and installation
