3. Simple Structure and Eazy Maintenance

Comparing conventional rudder, K-7 rudder could
obtain 50% higher l ift especially when the ship
runs at low speed.
Due to the reaction
force of flap during sharp turning,
recovery of trim could be achieved.
And also due to the high effect of
flap at low speed of the ship, K-7
rudder is suitable for operation of
ship in narrow water way.
The moving parts of the rudder are
simple and made of durable material, which
makes maintenance work easier.
1.K-7 The rudder consists of main rudder, flap fitted to the rudder by the hinge and link mechanism for moving the flap.
2.2 When the main rudder turns, the flap turning angle becomes more than 2 times of the main rudder. And the main rudder and the flap make big camber curve and create higher l ift from the stream from propellar.
3. In movement of l ink mechanism, flap angle is taken at constant ratio with main rudder angle, which fulcrum fixed on the hull. See also the left drawing.
4. Main rudder and flap are designed under optimum condition fluidically in order to minimalize rudder resistance on the sailing.
