FLAP TYPE
An Explanation of a Product
Flap type High Lift Rudder is a rudder system that generates high lift force by putting flap on the end of moving parts and then increasing the angle according to the position of a vessel's help with the aim of improving adjustment capability. It is highly efficient in decreasing safety accidents like collision at sea during sailings by decreasing turning radius of vessels. Especially, it has an advantage of capacity to steer vessels quite quickly when they sail a narrow sea route slowly.


Characteristics of a Product
1. Flap and Optimal Proportion of Equilibrium.
2. The Best Operation Performance at Low Speed
3. Minimization of Vibration and Noise
4. Simple Installment and Maintenance
5. Simple and Solid Connection System
6. Self-lubricating Bearing

PARTICULARS
1. RUDDER HELM ANGLE : 0~70˚ (MAX. 70˚)
2. FLAP ANGLE : APP. 75˚~110˚
3. RUDDER ASPECT RATIO : 1.0~2.0


SEMI-SPADE TYPE
An Explanation of a Product
As a rudder with rudder horn, it is being used in many vessels.


Characteristics of a Product
1. APPLIED NACA PROFILE
2. BUILT-UP TYPE RUDDER HORN
3. MINIMISE WEIGHT WITH HIGH TENSILE STRENGTH MATERIAL
4. OPTIMUM SIZE AND BALANCE RATIO
5. CRACK FREE

PARTICULARS
1. RUDDER HELM ANGLE : 0~35˚
2. RUDDER BALANCE : : 21~30%
3. RUDDER ASPECT RATIO : 1.0~2.0


TWISTED SPADE TYPE
An Explanation of a Product
As vessels are becoming more and more larger and their speed is becoming faster, a problem of the decline of propulsion efficiency and adjustment capability tends to occur owing to erosion made by cavitation. TWISTED SPADE TYPE can minimize the erosion of cavitation by minifying an incidence angle taking notice of the difference of angle of attack flow of the upper and lower sides of a propeller, being asymmetric TWIST-type up and down.

Characteristics of a Product
1. Efficient Design
2. Diminution of Noise and Vibration

PARTICULARS
1. RUDDER HELM ANGLE : 0~35˚
2. RUDDER BALANCE : : 21~30%
3. RUDDER ASPECT RATIO : 1.0~2.0


FISH TAIL TYPE
An Explanation of a Product
As a rudder whose shape of the cross section is like a fishtail, it can improve adjustment capability of vessels because it increases lift force at the end of a rudder, and it has a great steering specially at the low speed.
