Description

The present invention relates to ships that plan on water at speeds well in excess of 40 knots per hour.

Few high-speed boats, hydrofoils, and hovercraft that travel on water or at sea have hitherto exceeded 40 knots per hour.
In order to sail over the sea at 40 knots and at a speed of over 100 km/h, it is necessary to adopt a system that does not receive wave resistance. Such an example is seen when an amphibian rises from the surface of the sea, and the engine is equipped with enough power to allow the aircraft to fly. to fly.
However, the lower part of the fuselage of the amphibian is designed to receive waves and float up due to wave-making resistance. Gone.

In addition, in a structure in which the cabin and cargo compartment are installed on the floats with several large cylindrical floats in parallel, and the engine, etc. are installed, the center of gravity is higher than the center of buoyancy when the ship is stopped, resulting in remarkable stability. can not be used without missing. In addition, if a hollow float cracks due to a collision, it loses buoyancy at once, and there is a danger of overturning or sinking.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a hull structure and a propulsion system in which the wave-making resistance hardly increases even when the speed exceeds 100 km/h and the stability is maintained even in the stopped state.

A glider according to one aspect of the present invention for solving the above problems comprises a rectangular flat-bottomed float with a circular front shape, which is lightweight and similar in structure to the wing of an aircraft; A ballast tank is installed under the inside of the vessel for stability when the vessel is stopped. At the four corners, propulsion devices that can be raised and lowered and the direction of which can be changed are attached, and a fuselage-like cabin is provided in the center of the deck of the float for passengers and others of the aircraft. In addition, a plurality of propellers or a jet engine or other propulsion device is attached to the center of the float. When starting sailing, first send air to the ballast tanks to float the whole as much as possible, then operate the propulsion devices at the four corners of the float to move it forward, and when the float gradually rises to the surface of the water, the float The engine is fully opened, and when the bottom of the ship completely floats like a flying boat and the wave-making resistance is almost zero, it glides at high speed. When the float is in a gliding state, all the propulsion device screws at the four corners of the float are raised above the bottom of the ship, and nothing protrudes to the sea surface. It is a thing.

The float is laid with buoyant material under the deck so that the deck is at a position of about 50 cm above the surface of the water at the time of maximum load, and below that is a ballast tank divided into several sections, and the whole is Light and strong metal such as aluminum or carbon fiber should have strength to withstand gliding conditions.

In the unlikely event that the glider rolls over and the bottom of the ship is up, an escape port is provided through the float so that the passenger can escape from the floor of the cabin to the bottom of the float. keep it closed.

A vertical tail is attached to the rear of the deck so that the direction can be changed in a gliding state. The direction change of the glider when berthing and leaving port is done by the propulsion devices at the four corners of the float.

According to the present invention, even if there are only a few waves in the sea, the glider glides over countless wave crests, has good stability, has almost no wave-making resistance, and is entirely on the surface of the water. It is released from the relationship between the center of gravity and the center of buoyancy, and can sail at high speed in a stable state. In addition, the upper part of the float is covered with buoyant material, so even if the hull cracks due to collision with something, the buoyancy will not be lost and the stability can be maintained. When the glider glides over the surface of the sea in this manner, the main resistance is the resistance when the float collides with the wave crest. When the waves are high, they collide with high crests and the resistance increases. However, the front of the float and the bottom of the hull are smooth like the main wing of an aircraft, and although it slows down, it does not become a major hindrance to navigation. When it encounters a wave with a very long wavelength, such as a tsunami, it slows down and fills the ballast tanks to reduce speed but increase stability.

Embodiments of the present invention are described below with reference to the accompanying drawings.

Figure 1 shows the overall appearance of the glider according to the embodiment of the present invention. First, it is much lighter than hydrofoils and hovercraft, and its weight per unit volume is close to that of a large aircraft. is. Float 1 also has a structure similar to the main wing of an aircraft, and the main structural members are made of aluminum and carbon fiber. A cockpit and a cabin 6 are provided in the center of the float 1 with the minimum volume in a shape similar to the fuselage of an aircraft. In the case of a large ship, the cockpit and cabin 6 are placed inside the float 6 to some extent, but basically they are provided on the deck. The engine 4 is also attached to both sides of the central part of the float 1, and the vertical stabilizer 7 is also attached to the rear part.

FIG. 2 shows a cross-sectional view of the central part of the glider. From the floor of the cockpit in the center of the float 1 and the cabin 6, there is an escape port 9 leading to the bottom of the ship, and hatches 10 are attached to the top and bottom of the port so that they can be opened and closed. One or more engines 4 are mounted on the deck of the float 1 in the center or slightly behind. A gasoline engine or a diesel engine obtains propulsion by rotating a carbon fiber propeller 5 .

FIG. 3 shows a cross-sectional view of the glider slightly behind the bow. A buoyancy material 2 is filled under the deck of the float 1 . The amount of the buoyant material 2 is set to, for example, about 50 cm from the waterline to the deck even when the glider is fully loaded with passengers, cargo, fuel, etc., and a margin is provided to the extent that waves do not run up on the deck even in small waves. The structure of the float 1 is similar to the main wing of an aircraft, and is mostly made of lightweight aluminum, and partly titanium. Ideally, the bottom portion of the float 1 is made of carbon fiber. The lower half of the float 1 is a ballast tank 3, which is partitioned into several compartments or composed of independent ballast tanks like a submarine. Each ballast tank 3 is provided with a vent valve 11 and an inlet/outlet 12 for seawater. The ballast tank 3 is filled with seawater when the ship is stopped to enhance stability, and the stability is maintained by adjusting the ballast tank 3 when passengers get on and off. When leaving port, air is sent to the ballast tank 3 to float the hull and reduce wave-making resistance.

FIG. 4 is a side sectional view of two of the propulsion units at the four corners attached to the float 1, and a screw 13 is attached under the motor 14 of the propulsion units. When the gliding ship berths, these are lowered under the ship's bottom, and by changing the direction of the screw-13, the hull is moved back and forth and left and right. In addition, when the ship departs from port and speeds up, the screw-13 is set to full speed as the forward direction. As a result, the hull gradually rises due to wave-making resistance. At the same time, air is sent to the ballast tank 3 to float the whole tank as much as possible to reduce wave-making resistance. In this state, the engine 4 on the deck is fully opened to increase the speed so that the bottom of the ship is completely floated above the waves. In this state, the wave-making resistance becomes infinitely small, and in calm waves, it is possible to obtain a speed close to that of an aircraft.
