Flap Rudder I Type
Rudder angles of +/-45 degrees and additional 45 degrees of the flap permit extreme manoeuvres and dynamic positioning operations. Each ship is different and for some rudder configurations rudder angles of 65° Can be applied if a benefit for manoeuvring is expected. Also attractive is the improved course keeping performance and fuel saving obtained through smaller required rudder angles and smaller rudder area, compared to standard rudders.
The advantages of the flap rudders (I-type) are:
Optimum balance and flap area
Minimum steering gear size
Highest insurance against flexural vibration
High efficiency ratio design
Highest safety against cyclic stresses
Durable in heavy duty
Easy maintenance of link and hinge system
Flap Rudder II Type
This type is an economical Rudder and especially suitable for the small and low speed vessels such as River boats, supply vessels, tug boats, fishing boats or research vessels can take advantage of this type of rudders for their special purposes.
The advantages of the Flap rudder (II-type) are:
Better covering of propeller stream
Reduction of the remaining forward thrust
Easy installation
Increase of side thrust
Smaller rudder torque
Smaller steering gear
Less stresses of steering gear
