Embodiment Construction
[0029] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.
[0030] Such as Figure 1-4 As shown, it is a single wave-piercing deep V impact bow ship type in a preferred embodiment of the present invention. The ship adopts a deep V line shape from the bow to the tail as a whole, and the impact bow is adopted near the waterline of the bow. Near the waterline is vertical, and above the waterline adopts a backward-inclined wave piercing bow, so that a protruding bow is formed near the waterline.
[0031] The single-body wave penetration depth V impact bow ship type proposed by the present invention is mainly suitable for large-scale high-speed ships with a Fourier number Fn≥0.35, wherein:
[0032]
[0033] V—ship speed, kn;
[0034] g—gravitational acceleration, g=9.8m / s 2 ; ...

The invention relates to a single-hull wave piercing deep V-shaped impact prow hull form. The transverse sections of a ship from the prow to the stern all adopt a deep V-shaped line type, a portion near the prow water line adopts an impact type prow, the portion near the front end water line of the impact type prow is a perpendicular type prow, the portion above the water line adopts a tilt-back type wave piercing prow so that the portion near the water line forms a protruding prow. According to the single-hull wave piercing deep V-shaped impact prow hull form, the transverse sections of the ship from the prow to the stern all adopt the deep V-shaped line type, under the same displacement and scale, the water line is relatively long, the resistance is lowered so as to benefit the speediness, and the navigability and the ship turning ability can be obviously improved. The ship prow adopts the impact type prow, the portion above the water line adopts the tilt-back type wave piercing prow, so that the portion near the water line forms the protruding prow, active impact can be conducted on other ships which are near the water surface, and thus a strong confrontation property can be obtained; the portion above the water line adopts the tilt-back type wave piercing prow, so that the reserve buoyancy above the water line is reduced so as to benefit the seakeeping ability of the ship, and the wind area is small so as to benefit the wind resistance.
Description
technical field [0001] The invention relates to the technical field of ship shape design, in particular to a single-body wave-piercing depth V impact bow shape for large high-speed ships. Background technique [0002] After the adjustment and integration of national marine law enforcement forces, the existing patrol ships are mainly maritime ships and coast guard ships. The tonnage of existing patrol ships in my country has formed a complete series from 100t to 6000t, which is not much different from foreign law enforcement ships, but their speed is mostly around 20kn, and the tonnage of high-speed patrol ships is small, which is not confrontational. Compared with the maritime patrol law enforcement teams of developed countries, there is still a big gap between my country's patrol ships in terms of speed and maneuverability. [0003] From the point of view of the ship shape of large patrol ships at home and abroad, most of them adopt the form of conventional line and flared...
