High-speed ship additionally provided with stern wave suppression plates and control method of high-speed ship

Abstract

The invention discloses a high-speed ship additionally provided with stern wave suppression plates and a control method of the high-speed ship. The high-speed ship additionally provided with the sternwave suppression plate is characterized in that a fixed duck tongue type hydrofoil is arranged on ship bow and the active controllable stern wave suppression plates are arranged at stern; the duck tongue type hydrofoil is fixedly connected with the lower part of the ship bow; the stern wave suppression plates are symmetrically arranged on two sides of a hull center line, wherein the two plates are the same and are both rectangular solid plates; the two ends of the stern wave suppression plates are hinged with support frames; and the support frames are fixedly mounted on a stern transom plate,and play the function of stabilizing the stern wave suppression plates. The angles of the stern wave suppression plates are adjusted to rotate within the range of 0 degree to 10 degrees; the duck tongue type hydrofoil and the stern wave suppression plates can increase vertical motion damping and obtain torque for suppressing pitch; the stern wave suppression plates can also improve a tail flow field and reduce ship resistance; and the seaworthiness, seakeeping and rapidity of the ship can be improved by combining the duck tongue type hydrofoil with the stern wave suppression plates.

Description

technical field [0001] In order to improve the rapidity and seakeeping performance of the ship, the present invention specifically provides a fixed duck-tongue hydrofoil at the bow and an actively controllable stern wave plate at the stern. Background technique [0002] As an important platform for maritime operations, a ship must have excellent speed and seakeeping, which is related to the vitality and combat effectiveness of the ship. The fouling phenomenon of the ship and the mechanical wear of the propeller will increase the power consumption of the main engine. By installing a stern wave plate at the stern, the flow field at the stern of the ship can be improved, the wake wave can be reduced, and the "imaginary length" can be increased, thereby reducing the ship's resistance , the rapidity is improved. As the ship sails in waves, there will be swaying motions, among which pitch, roll and heave have a great impact on the comfort of the crew and the combat capability of ...
