One of the important things in a ship’s rudder design is the incidence angle of the rudder inflow to improve rudder cavitation performance. In the present study, the rudder inflow is measured by a 3-D LDV (laser Doppler velocimetry) system in a large ...

Resistance and propulsion performance of a twin skeg ship with different rudder angle [PDF]
Rudder angle will change the flow field, resulting in different loads and interactions on the hull-propeller-rudder, which will affect the resistance and self-propulsion performance of the ship, and this effect will be amplified on the twin skeg ship ...

A Fault-tolerant Steering Prototype for X-rudder Underwater Vehicles
The X-rudder concept has been applied to more and more autonomous underwater vehicles (AUVs) in recent years, since it shows better maneuverability and robustness against rudder failure compared to the traditional cruciform rudder.

A numerical and experimental study on the performance of a twisted rudder with wavy configuration
In this paper, a Wavy Twisted Rudder (WTR) is proposed to address the discontinuity of the twisted section and increase the stalling angle in comparison to a conventional full-spade Twisted Rudder (TR).

Twisted rudder for reducing fuel-oil consumption
Three twisted rudders fit for large container ships have been developed; 1) the Z-twisted rudder that is an asymmetry type taking into consideration incoming flow angles of the propeller slipstream, 2) the ZB-twisted rudder with a rudder bulb added onto ...

Analysis of Known and Construction of New Mathematical Models of Forces on a Ship's Rudder in an Unbounded Flow [PDF]
The forces arising on the ship's rudder at different angles of attack in an unbounded flow are investigated. The components of the resulting force on the rudder are represented in terms of the rudder lift and drag forces, as well as in terms of the ...
