Definitions

  • the present invention relates to a ship control system, and more particularly to a system device that can reduce the ship's navigational resistance.
  • BACKGROUND OF THE INVENTION In order to improve the speed of a ship, it is necessary to reduce the resistance of the ship's navigation in every possible way, which requires studying the resistance of the ship during navigation. When the ship is sailing, the lower part of the hull's waterline is immersed in the water, and the rest is in the air. Therefore, the total resistance to the movement of the ship includes water resistance and air resistance. Since the density of water is much greater than the density of air, water resistance is the main resistance. Water resistance can be divided into viscous resistance and wave-making resistance according to the cause.
  • Viscous resistance The resistance due to the viscous action of water, including frictional resistance and vortex resistance. Frictional resistance is caused by the adhesion of water to the surface of the hull, which accounts for the largest proportion of the total resistance of the ship. The frictional resistance can account for 80% of the total resistance for low-speed ships and about 50% for high-speed ships. Therefore, the patent of the present invention is mainly solved to reduce the resistance during the navigation of the ship. Summary of the invention
