Performance enhancement of the roll stabilization systems used for ships.

Reducing the ship rolling motion is an important subject of the ship motion control. In addition, the fin stabilizer is one of the most effective ship stabilizers, which plays an important role in decreasing fuel consumption, improving the ship seaworthiness, giving a longer life for the ship, ensuring the equipment on the ship-working better and making the ship members feel comfortable, advance battle effectiveness of the naval ships. In our research, we concentrate on a hydrofoil fin stabilizers, which are used in both sides of ships. Our aim is to profile the optimum design of foils to enhance the effectiveness of ship stabilizers by more investigation in different experimental models& comparing them. Finally, we have reached the best form and the best dimensions of hydrofoil fin stabilizers used in the experiment, which is NACA-04, which is better than the other foils. [ABSTRACT FROM AUTHOR]
