DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pneumatically supported high-speed ship, and more particularly to a high-speed ship capable of adjusting the inclination of a hull by providing pneumatic chambers at front, rear, left and right of a lower part of the hull. .

[0002]

2. Description of the Related Art Heretofore, a so-called pneumatic composite support ship has been known. Thus, the ship has a gate-shaped catamaran at the bottom, a bow seal provided on the bow side, a stern seal provided on the stern to shut off the outside, and a pneumatic chamber provided therein. Further, a cushion pressure control louver and an attitude control underwater fin are provided to control the sway of the hull generated when sailing in the waves, and the attitude of the hull is controlled.

[0003]

The above-mentioned conventional pneumatic composite support ship has one large air pressure chamber at the bottom of the hull, and confine gas between the hull and the liquid level.
Air pressure acting on the trapped gas supports the weight of the hull. In addition, hull sway that occurs when navigating in the waves is controlled by cushion pressure control louvers and attitude control underwater fins. The underwater fins cannot be expected to keep the hull horizontal when the hull is stopped.

[0004] Thus, the air pressure chamber only has the function of supporting the weight of the hull traveling on the boundary between the liquid phase and the gas phase, and has the inclination of the front-rear, left-right, and right-and-left directions during the navigation in the waves. It can hardly be expected for attitude control. Therefore, as described above, a special device for controlling the attitude is required, which causes an increase in cost. Therefore, there is a technical problem to be solved in order to be able to adjust the inclination of the hull in the front-rear and left-right directions by using the air pressure chamber without maintaining a special attitude control device so that the hull can be maintained horizontal. It is an object of the present invention to solve the problem.

[0005]

SUMMARY OF THE INVENTION The present invention has been proposed to achieve the above-mentioned object, and is provided at a bottom portion of a hull, between two front sides vertically provided in a longitudinal direction of the bottom portion . The two halls

An object of the present invention is to provide a pneumatically-supported high-speed ship configured to be able to turn following movement .

[0006]

According to the present invention, four or more air pressure chambers are provided facing each other on the front, rear, left and right of the bottom of the hull, so that air is supplied to each air pressure chamber and the air is confined in each air pressure chamber. Thus, the air pressure of the air generates a levitation force on the hull, and the air pressure is further increased to reduce the contact portion between the rigid hull and the water and to sail by the thrust of the propulsion device. It becomes possible.

Thus, when the hull sails in the waves,
The hull may not be able to maintain horizontal front and rear or left and right due to the impact of the waves. In such a case, for example, a sensor for detecting the forward / backward / left / right inclination of the hull is provided, and the amount of air in the corresponding pneumatic chamber is automatically adjusted based on the detection value of the sensor to thereby adjust the forward / backward / left / right hull. Naturally, the inclination can be adjusted , but the present invention is installed in each pneumatic chamber.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to FIGS. FIG. 1 is a perspective view showing a bottom surface of a pneumatically supported high-speed ship 1 of the present invention. In FIG. 1, the pneumatically supported high-speed ship 1 (hereinafter, simply referred to as a high-speed ship) has a bottom portion 2 with a wall 3 at the longitudinally opposite flank 3 and a central portion between the flank 3.
a are vertically arranged to partition left and right, and seals 4, 4,... are rotatably mounted on the bow 1a side, the stern 1b side, and intermediate portions thereof, respectively. The seals 4, 4,... Are formed of, for example, a rubber material having bones in a substantially rectangular shape as shown in the figure. The front sides 3, 3 and the wall 3a are formed of a rigid body, and the seals 4, 4,... Are in close contact with the respective side faces of the front sides 3, 3, and the wall 3a. formed freely rotating to follow the fluctuations. Therefore, the upper ends of the seals 4, 4... Are rotatably connected to the bottom 2 of the hull 1 by hinges 5, 5. , 7... Are provided.

Thus, in this embodiment, the pneumatic chambers 6, 6, 6 are opposed to each other in the front, rear, left and right directions by the two front sides 3, 3 and the wall 3a and the seals 4, 4,. Four chambers 6 and 6 are formed and are isolated from the outside. Thus, the number of the pneumatic chambers may be four or more. Further, the pneumatic chambers 6, 6,
6, 6 are provided with air supply / discharge devices (not shown), respectively, and are provided with front / rear / left / right tilt detection sensors (not shown). When detecting the tilt angle, the detected value is controlled by a control unit (not shown).
The control unit adjusts the air amount by operating the air supply / discharge device so as to adjust the inclination of the high-speed ship 1 in the front-rear and left-right directions to maintain the horizontal level. The ship 1 is restored to a horizontal position so that this state can be maintained. Of course,
