Disclosure of Invention

In order to overcome the technical problems in the prior art, the application provides a water craft.

The specific technical scheme is as follows: the ship comprises a ship body, wherein the cross section of the ship body is of an inverted T shape, the transverse direction of the T shape is a wide and sinking-free floating body, and the vertical direction of the T shape is a long and narrow cabin; the floating body is of a bottom flat structure, and the cabin is of a top flat structure; the head of the ship body and the tail of the ship body are of sharp round structures, the front vertical surface of the cabin and the front vertical surface of the floating body are vertically arranged, the front vertical surface of the cabin can form a hard sail, the head of the cabin is provided with a pneumatic driving device, the pneumatic driving device comprises an air inlet, and the head of the ship body and the floating body enclose an air flow channel communicated with the air inlet; the tail part of the floating body is provided with a water spraying driving device with a steering and reversing device.

In the technical scheme, the cross section of the ship body is of an inverted T shape, the transverse direction of the T shape is a wide and sinking-free floating body, and the vertical direction of the T shape is a long and narrow cabin; after the displacement and the length of the ship are determined, the width of the never-sinking and floating body is increased, the balance is better, the draft is reduced, the peak value of the pressure difference between the head water and the tail water under the ship is reduced, and the peak resistance is reduced. The cabin is long and narrow, the width is reduced, the center of gravity is in the middle, the balance is better, and the wind shielding area of the water part is reduced, so that the air resistance is reduced.

The never sinking and floating body is designed to be flat at the bottom, and the cabin is designed to be flat at the top, so that the rise and fall of the bow and the stern caused by lifting force or pressure generated during running are avoided, the wind intercepting and water intercepting area is increased, and the resistance is increased.

The pneumatic driving device is utilized to pump the gas upwards and push the gas backwards from the front lower part of the bow, and the forward power is obtained, and meanwhile, the pressure of the bow is reduced, so that the resistance is reduced and the power is increased; meanwhile, power for maintaining heading is provided for the bow, and the wind resistance and wave resistance of the ship are enhanced. The tail of the floating body is designed into a sharp circle structure (formed by adding a semicircle to a part surrounded by three tangent equal circles), and the rear vertical surface is vertical. When the ship advances, the distances from the water at the two circle centers behind the floating body to each point at the stern are equal, so that the time for supplementing the cavity left by the ship is equal, vortex and turbulence are not easy to generate, and resistance is reduced; similarly, the cabin is designed into a tail tip circle, so that the resistance can be reduced.

The tail part of the floating body is provided with a water spraying driving device with a steering and reversing device. The flexible steering is realized, and the advantage of large water spraying driving thrust is exerted. The low-speed water spraying drive and the high-speed water spraying air entrainment drive fully play the advantages of large water thrust and quick air propulsion; the water craft can travel at speeds of several hundred knots.

Further, the floating body is of a bottom flat structure, and the cabin is of a top flat structure. The lifting force or pressure generated during running is avoided to cause the lifting of the bow and the stern so as to increase the wind and water interception area and increase the resistance.

Further, the air driving device comprises a propeller, an axial flow fan and a jet engine. The air is pumped upwards and then pushed backwards from the front lower part of the head of the cabin, and the air pressure of the head of the cabin is reduced so as to reduce the resistance and increase the power when the forward power is obtained; meanwhile, power for maintaining heading is provided for the bow, and the wind resistance and wave resistance of the ship are enhanced.

Further, the sharp circle structure is formed by enclosing the part except the tangent point of two circles in the horizontal direction in 3 equal-diameter circles which are distributed in an inverted triangle manner and tangent, and the rest part of the 3 rd circle is enclosed after the semicircle is cut off.

Furthermore, the front lower part on the air inlet is provided with an inverted U-shaped flow guiding device, two end feet of the inverted U-shaped flow guiding device are communicated with the floating body, and the inverted U-shaped flow guiding device can ensure that air is not introduced from the upper, left and right sides.

Further, the air flow channel is formed by enclosing the inverted U-shaped flow guiding device, the head of the cabin and the floating body, and the air flow channel gradually becomes smaller from the opening of the inverted U-shaped flow guiding device to the inside. The airflow channel is gradually reduced, so that the flow speed of the gas is gradually increased, the air pressure is gradually reduced, the resistance is gradually reduced, the pressure reduction and drag reduction effects are improved, and further, the larger resistance is reduced, and the larger power is obtained. At the bow, the hold is part of both the hold and the suction channel; the floating body which never sinks is not only a floating body but also a part of the air suction channel, and can play a role in reducing resistance and increasing power.

Further, the floating body is of a steel-glass fiber reinforced plastic-foam-wood board-glass fiber reinforced plastic structure, a keel is welded on the steel pipe, a bottom wall and a peripheral wall are welded on the steel pipe, glass fiber reinforced plastic is pasted on the steel pipe, foam is filled on the steel pipe, the wood board is covered for fixation, the steel pipe is sealed by glue, and finally the glass fiber reinforced plastic is pasted on the steel pipe. When in use, the floating body can be spread with sand to prevent skid. The steel structure is firm; the glass fiber reinforced plastic has good corrosion resistance; foam filling never sinks and is not afraid of breaking; the top of the wood board cover is sealed by glue, so that the difficult problem that the wood board can not be welded and can not be directly pasted with glass after being filled with foam is solved. The floating body formed by the floating body has firm structure, good anti-corrosion performance, collision resistance, never sinking and high safety performance.

Further, water spraying driving devices are installed on two sides of the head of the ship body, and water sucking ports of the water spraying driving devices are located below the sharp round head of the ship body and specifically below the sharp point of the sharp round structure. The water spraying driving device can absorb water from the lower part of the part surrounded by the three tangent equal circles of the sharp circle of the head, so that the water pressure in front of the ship head can be reduced, the resistance is reduced, and further, more power is obtained.

Furthermore, a periscope or a perspective mirror is arranged above the head of the floating body. The periscope or the perspective mirror can solve the problem of the obstruction of the sight of a driver.

Compared with the prior art, the application has the beneficial effects that:

the problem that a ship with a small draft can fly at a high speed at a very low altitude and with increased resistance when traveling at a high speed is caused by the fact that the resistance is mainly due to the pressure difference of the air at the bow and the stern of the ship, rather than the pressure difference of the water. The method comprises the following steps: the ship has both an underwater portion and an above water portion. When the ship runs at high speed, the resistance mainly comes from the water pressure difference and the air pressure difference at the bow and the stern. Obviously, when the speed is increased continuously, the water pressure and the air pressure at the stern are close to 0; that is, the head and tail gas pressure difference peak value of the water part is close to one atmosphere (about 10 meters of water column); while the head and tail differential pressure peaks under water are determined by the draft of the vessel. Draft 1 meter, bow average water pressure is one twentieth of atmospheric pressure (water pressure at 0.5 meter under water is average water pressure); for example, the draft is 2 meters, and the average water pressure at the bow is one tenth of the atmospheric pressure (the water pressure at 1 meter under water is the average water pressure); the draft is 10 meters and the bow average water pressure is only one half of the atmospheric pressure (the water pressure at 5 meters under water is the average water pressure). Thus, a ship traveling at high speed, particularly a ship having a small draft, has resistance mainly from the pressure difference of the gas at the bow and the stern of the ship, not the pressure difference of the water. The water airship is composed of the floating body which never sinks, the floating body can be prevented from being lifted off the water surface when the ship runs at high speed, the draft of the ship can be reduced, balance is ensured, and safety is improved. In addition, the ship is driven by a mode of head air driving and tail water spraying driving, and the ship head is provided with the air driving device, so that not only can the forward power be obtained, but also the air at the head of the ship cabin can be pumped away, and the pressure of the ship head is reduced, so that the peak resistance is reduced.

The ship body is in a structure with round head tip, round tail tip, flat bottom, flat top and vertical front and rear faces, can reduce resistance and avoid generating lifting force, and provides heading-keeping forward power for the bow so as to improve the storm resistance of the ship; the low-speed water spraying driving and the high-speed water spraying air entrainment driving fully exert the advantages of large water thrust and quick air propulsion.

The water craft of the present application can travel at several hundred knots. Has firm structure, good corrosion resistance, no fear of crashing and never sinking.

The application has the beneficial effects that: 1. the problem that a ship with a small draft can fly at a high speed at a very low altitude and with increased resistance when traveling at a high speed is caused by the fact that the resistance is mainly due to the pressure difference of the air at the bow and the stern of the ship, rather than the pressure difference of the water. The method comprises the following steps: the ship has both an underwater portion and an above water portion. When the ship runs at high speed, the resistance mainly comes from the water pressure difference and the air pressure difference at the bow and the stern. Obviously, when the speed is increased continuously, the water pressure and the air pressure at the stern are close to 0; that is, the head and tail gas pressure difference peak value of the water part is close to one atmosphere (about 10 meters of water column); while the head and tail differential pressure peaks under water are determined by the draft of the vessel.
