SMART MANOEUVRING WITH THE BECKER FLAP RUDDER
Higher lift due to optimised pressure distribution The Becker Flap Rudder is based on the articulating flap principle, where the hydrodynamic side force (rudder lift) results from the pressure distribution around the rudder blade. The flap rudder achieves a significantly higher-pressure distribution on both the suction and pressure sides, leading to greater lift. After the rudder reaches its stall point, only the positive pressure component remains. Even here, the Becker Flap Rudder exhibits a higher- pressure distribution compared to NACA profiles, which makes the Becker Flap Rudder especially powerful in terms of generated lift and efficiency.

Up to 90° for precise manoeuvring The Becker Flap Rudder features an additional, moveable flap which amplifies the prescribed rudder angle. A rudder angle of 45 degrees results in a flap angle of 90 degrees. Thus, it responds to smaller rudder angles with significant lateral forces and is especially suitable for ships that need to operate in narrow or restricted water ways. This rudder is very effective in its response, generating significant manoeuvring advantages from small rudder angles onwards.
