Flap rudder Heracles

for ships

HERACLES stands for High Efficiency Rudder Acting with Closed Linkage providing Enhanced Safety. Its sophisticated design incorporates the benefits of a flap mechanism, which is protected in a hydrodynamically-shaped top section of the rudder blade with an increased flap angle ratio. This provides both high manoeuvrability at high rudder angles as well as smooth steering response and low resistance under steering. Enhanced safety is achieved via a safety device on the flap axis, which prevents both the mechanism from being damaged as well as the rudder being rendered inoperable due to flap blockages and obstruction. These features make the Heracles rudder the rudder of choice when you demand high efficiency manoeuvring, excellent course keeping, low fuel costs and a long service life.
