Becker Twist Rudder
Twisted-profile ship rudder that uses the propeller slipstream rotation to reduce cavitation, erosion and drag; options include heel pintle, King Support bearing and rudder bulb.
Description
The Becker Twist Rudder is a rudder with a twisted profile designed to make use of the rotating flow generated by the propeller. The twist prevents low-pressure areas on the rudder surface that cause cavitation and erosion, allows higher rudder angles at higher speeds and reduces rudder drag, recovering losses from the propeller slipstream.
Key features
- Reduced cavitation and rotational losses
- Power savings through recovery of propeller slipstream losses
- Optimised profile for reduced drag
- Lighter weight with no cast parts
- Minimised self-induced cavitation, extending rudder life and reducing maintenance
Options
- Heel pintle and heel pintle bearing – for smaller vessels such as fishing boats, offshore ships, workboats and tugs; the heel pintle arm also acts as a rope guard protecting the rudder from ropes and nets.
- King Support (KSR) – main neck bearing integrated in the rudder blade, mainly for larger ships with a rudder area over 20 m²; allows slimmer, lower-resistance profiles and lower stresses on neck and carrier bearings.
- Rudder bulb – reduces the propeller hub vortex to improve propulsive efficiency and reduce cavitation risk.
Applications
- General cargo vessels
- Container vessels
- Ferries and vehicle carriers
- Passenger vessels
- Gas carriers
