Becker Flap Rudder with Closed Linkage

Becker Flap Rudder with Closed Linkage

The Becker Flap Rudder with closed linkage system is the solution for the most difficult environmental conditions. Its sophisticated design incorporates the benefits of a flap mechanism, which is protected in a hydrodynamically-shaped top section of the rudder blade with a progressive flap angle ratio. This provides improved manoeuvrability at high rudder angles, smooth steering response, low resistance under steering and excellent course keeping. The closed flap linkage system is designed for high durability and protection against excessive forces. It also provides optimum protection of the linkage system from ice and sand.

Another advantage of the closed linkage system is noise reduction while steering. This allows rudder operation even while performing sensitive acoustic measurements.

Enhanced safety is achieved via an overload protection of the rudder flap, which prevents both the mechanism from being damaged as well as the rudder from being rendered inoperable due to flap blockages and obstruction. The integrated friction clutch protects the rudder flap against any damage from outside. In case the rudder flap becomes struck, the clutch will slip and give way to the overload. The flap will self-centre after the rudder is steered hard portside and starboard.

  • General cargo carriers/Heavy lifters
