Technical Field

The invention relates to the technical field of ships, in particular to a wave-breaking accessory and a wave-breaking ship.

Background

The high-speed ship needs to overcome the navigation resistance to reach the navigation speed indexes including the continuous high navigation speed index and the maximum navigation speed index, and in order to reach the two high-speed indexes, a high-power host needs to be adopted and the underwater projection area of the ship needs to be reduced as much as possible so as to reduce the resistance.

The above-mentioned traditional way of increasing the speed of a ship brings the following main problems:

high speed ships are costly. To meet the requirement of high navigational speed, a high-speed ship is generally required to be provided with a main machine with higher power, and the main machine is a main part of the whole ship cost, generally reaches 30 percent, so that the procurement cost of ship construction is increased.

High speed ships are less economical. In order to reach the maximum navigational speed index, a matched high-power main engine is usually selected, but a high-speed ship usually runs at a continuous high navigational speed or an economic navigational speed, so that the power of a power system is excessive, and because the main engine does not run at a matched power section frequently, parts are easy to wear when the main engine is not in the optimal running state for a long time, the oil consumption rate is high, and the economical efficiency is poor when the ship runs at a lower speed.

The operability is insufficient, and the forward projection area needs to be reduced as much as possible due to resistance reduction, so that the maneuverability of a high-speed ship is insufficient, the course stability is poor, and the disadvantages of keeping a flight path and safely navigating are caused.

Therefore, an optimized appendage is urgently needed to solve the technical defects on the premise of not greatly changing the shape of the high-speed ship.
