Becker Twisted Trailing Edge Rudder

The Becker Twisted Trailing Edge (TT) Rudder is the combination of a high-lift Schilling® profile and a plane profile. This combination assures very good manoeuvrability with the advantages of the Schilling® profile, but with lower drag at the same rudder size. The idea behind the TT Rudder was optimisation of the use and area of the fishtail trailing edge. The fishtail itself is a stagnation area and besides accelerating flow to gain additional lift forces, it produces higher drag. To reduce the drag Becker Marine Systems focuses the fishtail trailing edge on the most effective area of the rudder referencing the rotation of the propeller slipstream. The other side of the fishtail trailing edge is plane and the drag produced by the fishtail is thus minimised. In addition, the TT Rudder improves course keeping due to the rudder’s fishtail shape.

Providing high lift forces with no moveable parts, the rudder assures reduced maintenance and safe manoeuvring, also in ice. All in all, this rudder type is the best compromise of manoeuvrability and efficiency.
