Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a high-speed sliding single-

The present invention relates to a high-speed sliding-type single-acting ship having a fluid flow portion for reducing an anti-wave wave, and more particularly, To a high-speed sliding-type single-acting vessel having a fluid flow portion for reducing the anti-submarine wave which can be induced to the central portion of the rear face to reduce the anti-submarine waves generated on the water surface.

Since the ship is a means of transporting water from the watercraft, the hull constituting the ship during the operation of the ship is subjected to the flow resistance of the fluid.

There are frictional resistance and pressure resistance in the flow resistance acting on the hull, and frictional resistance is a resistance element which occupies most of the flow resistance acting on the hull. Therefore, researches for reducing frictional resistance have been continuously carried out.

For example, Japanese Patent Laid-Open No. 10-1104881 discloses a ship having a hull which is designed in a flow-resistance-reduced shape. More specifically, the bow of a ship below the draft line and the stern And a flow control groove or a flow control projection is formed on a side portion between a stern and a stern to reduce the resistance of the fluid in the water to increase the propulsion efficiency.

On the other hand, the ship wave is a wave generated when a ship moves. It is composed of a diverging wave propagating the wave to the left and right of the ship and a transverse wave propagating in the form of traversing the wave center line from the back of the ship. wave.

As described above, since the wake-up is generated due to the anti-collision waves generated when the ship moves, there is a problem that the combat ship for combat purpose tends to be exposed to the wake-up tracking radar.

In addition, when a ship moves in a port or a narrow waterway, the Hangzhou wave affects a small-sized ship or an underwater structure that is docked in the port and causes damage.

Specifically, a low-speed small sailboat having a hull having a bottom and a stern round shape spreads in a form in which the waves generated at the bow and the waves generated at the stern are separated as shown in Fig.

On the other hand, as shown in FIG. 2, a high-speed sliding single-acting ship having a stern-shaped hull has a structure in which a wave generated at a bow and a wave generated at a stern are combined to form a large anti- And when the stern of the straight type bottom is pressed from above the water, it generates more waves than the low-speed small sailing boat with round bottom and stern.

In other words, the Hangzhou wave generated from the bow occurs in a similar form in a small sailing boat or a high speed sliding single acting type ship, but a high sliding type single acting type ship causes a lot of Hangang waves due to the square shape of the stern.

Also, in the case of a high-speed sliding type single-acting vessel, as shown in FIG. 3, a fluid flowing along the side surface of the hull reaches the tip of a rectangular stern, resulting in a fluid flow interruption or a swirling vortex This vortex phenomenon has a problem that the propulsion force of the understanding vessel is impeded, leaving a distinctive Hangzhou wave and wake.

On the other hand, in the case of the above-mentioned Japanese Patent No. 10-1104881, a structure for reducing the fluid resistance in the water is disclosed, but the problem caused by the anti-circular wave as described above can not be solved. In order to solve the problems caused by the Hangzhou wave, it is composed of a multi-hull ship with less occurrence of the Hangzhou wave than the single-hull type ship which generates the Hangzhou wave.

However, there is a demand for measures to solve the above-mentioned problem of the Hangzhou wave even in a ship made of a single-acting hull.

As shown in FIGS. 4 and 5, the high-speed sliding single-acting ship 100 having the fluid flow-reducing fluid flow portion according to the embodiment of the present invention has a plane shape of a stern of a rectangular shape .

In order to reduce the kelvin wave generated on the surface of the high-speed sliding single-acting vessel 100 having the fluid flow portion for reducing the anti-wave wave according to an embodiment of the present invention, the anti- The fluid flow portion 110 is formed on the water line of the high-speed sliding single-acting vessel 100 provided.

A part of the anti-submarine wave generated on the sea surface through the fluid flow unit 110 is guided to the center portion of the rear surface of the hull of the high-speed sliding single-acting ship 100 equipped with the fluid flow portion for anti- The occurrence of the wake can be suppressed.

4 to 6, the fluid flow unit 110 is formed in the form of a groove connecting a side surface and a rear surface of a draft line of the ship 100, , An anti-resonant wave on the surface of the water flowing along the side of the hull of the high-speed sliding single-acting ship (100) equipped with the fluid flow for anti-quake-wave reduction through the groove-shaped fluid flow unit (110) 100 to the hull rear center portion of the hull.

Particularly, in the normal fluid flow unit 110, an anti-sudden wave generated in a middle-low-speed propulsion of a high-speed sliding single-acting ship 100 having a fluid flow portion for reducing the anti-submarine wave whose planar shape of a stern is formed in a rectangular shape, To the rear center portion.

On the other hand, in the case of a high-speed sliding single-acting vessel 100 having a fluid flow portion for reducing the anti-submarine wave whose planar shape of the stern is a rectangle, a stern trim is generated in which the athlete is heard while the athlete is submerged At this time, as the drag force is lowered by the induction action of the anti-static wave by the fluid flow unit 110, the additional acceleration can be smoothly performed.

Specifically, the fluid flow unit 110 includes a side surface 110a that contacts the anti-quake wave on the sea surface to guide the anti-quake wave to the center of the rear surface of the hull, a lower surface of the side surface 110a, A lower surface 110b connected to the rear surface and an upper surface 110c extending to the upper side of the side surface 110a and connected to the side surface and the rear surface of the hull.

The fluid flow portion 110 (120) protruding from a stern position adjacent to the rear of the main body (120).

Since the extended flow unit 120 is formed to be connected to the fluid flow unit 110, it is possible to further reduce the swirling phenomenon caused by the anti-swinging waves and the anti-swinging waves passing through the fluid flow unit 110, So that it can be effectively reduced.

That is, the side surface of the fluid flow portion 110 contacting the anti-submarine wave so that the anti-submarine wave can be guided to the central portion of the rear surface of the hull of the high-speed sliding single-acting vessel 100 having the anti- Side surface 120a of the elongated flow portion 120 in contact with the anti-divergent wave portion 110a and the side surface 120a of the elongated flow portion 120 contacting the anti- So that the anti-resonant wave is naturally induced to consume energy, and further induces the anti-resonant wave to the side far from the rear center of the hull.

As shown in FIGS. 7 and 8, the extended flow portion 120 is formed such that the width thereof becomes gradually smaller toward the rear, more specifically, the upper and lower widths are formed to be the same, Can be formed to be gradually smaller.
