Description

A method and application for fast response steering of watercraft

Technical field

The invention relates to ship propulsion technology, in particular to a method and application for fast response steering of a watercraft.

Background technique

Ships possessing high energy efficiency at high speeds are the eternal goal pursued by ship technology research.

The reality is that even in today's society with advanced technology, the problem of ship speed and energy efficiency is still an objective worldwide problem, and no ideal solution has been found so far.

Analyzing ship navigation resistance and propulsion technology can enhance our understanding of the limitations and deficiencies of current propulsion technology, and help open up useful ideas for solving the problem of ship speed and energy efficiency generally low.

Qualitative analysis of the main resistance of the ship's navigation: at least the following navigational resistances exist in the ship's navigation——

When a ship is sailing, the front water body is like a water wall blocking the advancement of the ship. The ship needs to break through the water wall to move forward. The infinite thickness of the water wall means that the ship needs to continuously break through the front water wall to keep moving forward. The blocking force of the water wall encountered by the ship sailing forward can be called the frontal navigation resistance of the ship, or the sailing resistance against the water.

Due to the fluid nature of water, when the ship's bow hits the water in front of the ship, waves will be stirred up when the ship sails forward. The formation of the wave at the bow of the ship is equivalent to throwing up the water in front of the ship. . Obviously, the appearance of waves in the bow of a ship is caused by the ship moving forward, so this force can only be provided by the ship moving forward. Since this force is provided by the ship sailing forward, it can be known from the law of Newtonian force and reaction force that this force will in turn act on the ship sailing forward, which constitutes another type of ship sailing resistance that is different from the headwater sailing resistance. In addition, the formation of waves at the bow of the ship is equivalent to pushing up the height of the water wall that needs to be breached in front of the ship, and such waves will develop along the side of the ship to the stern due to wake, which will further increase the sailing resistance of the ship. In order to distinguish it from the sailing resistance of the ship, the sailing resistance of the ship caused by the bow wave is called the wave making resistance of the ship.

There is a ship passing by in the water body, and the immersed part of the ship body must be discharged to create a regional vacuum environment at the rear of the ship. Due to the viscosity of the water and the water pressure adjacent to the regional vacuum environment, the water pressure is greater than that inside the regional vacuum. Pressure, adjacent water bodies must enter to fill up the vacuum in this area, resulting in large eddy currents and turbulence, which will form a high bow and low pressure difference between the bow and stern of the ship. This pressure difference is also part of the ship’s navigational resistance and will consume The ship's propulsion force causes the ship's speed to decrease. In order to distinguish it from the resistance of other ships, this resistance is called viscous pressure resistance.

Due to the viscous nature of water, the water body will produce viscous resistance equivalent to frictional resistance against the immersed surface of the ship when the ship is sailing;

When the ship uses the stern rudder to change direction, the navigation resistance of the ship also includes the stern rudder resistance. The resistance on the stern rudder is essentially the same in nature and type as the various resistances experienced by a sailing ship. It only accounts for a small proportion of the total resistance experienced by the ship, but it is still the existence of resistance that should not be ignored.

When the ship is sailing at high speed, the air resistance of the ship should not be ignored.

The sailing resistance, wave making resistance and viscous pressure resistance constitute the absolute bulk of the ship's sailing resistance.

The factors that determine the magnitude of the ship's sailing resistance are not only highly related to the design of the ship type, but also closely related to the ship's speed. The ship's sailing resistance is a function that is quadratic related to the ship's speed. A small increase in the speed of a ship in a high-speed sailing state can lead to a substantial increase in the resistance of the ship encountered by the ship. The higher the speed, the greater the increase in the resistance of the ship. These laws of ship navigation resistance have all been clarified for ship technology research.

In fact, the factors that determine the resistance of a ship's navigation are also closely related to the propulsion mode of the ship using the propulsion device and the deployment mode of the propulsion device on the ship. So it is necessary to learn more about ship propulsion technology.

Qualitative analysis of main ship propulsion technologies:

The current ship propulsion technology can be roughly divided into three categories from its propulsion principle and promotion and application level: propeller propulsion, water jet propulsion and straight-propeller propulsion (or called straight-wing propulsion, flat-rotating blade propulsion).

Propeller propulsion technology has a long history and is the most widely used. It is the absolute main propulsion technology of ships. Existing propeller propulsion technology is still in continuous development and progress. Based on propellers, such as counter-rotating propellers, controllable pitch propellers, ducted propellers, nacelle propellers, slightly driven propellers, tandem propellers, and large diameters have been developed. Multiple technologies such as low-speed propellers, and even ship propulsion technologies that combine water jet propulsion and propeller propulsion have emerged. The so-called shaftless pump propulsion technology belongs to the emerging propulsion technology, and its essence should also be attributed to the propeller propulsion technology.

Water jet propulsion includes pump jet propulsion and magnetic fluid propulsion. Magnetic fluid propulsion is an emerging technology with a short history of birth. The overall technology is being further improved, and its application range is very limited; the water jet propulsion technology was born very early, but it has been silent for a long time, and it has not developed until the past 20 or 30 years. And it's becoming more prominent. Western ship power manufacturing powers are committed to the development of large-scale and modular pump-jet propulsion technology, so that it can be applied to large ships, and water-jet propulsion technology is listed as an important direction for future ship propulsion technology development.

Straight-propeller propulsion is relatively rare, and is generally used in ships with large load changes and high maneuverability requirements, such as tugboats, ferries, and minesweepers. It has a narrow application range and small impact.

In view of the narrow application range of straight-propeller propulsion and the small impact area, in order to simplify the analysis, only propeller propulsion and pump jet propulsion are selected as the analysis objects. And only analyze their installation and deployment and water entry methods to help understand and understand the limitations and deficiencies of these two propulsion methods in terms of ship speed and energy efficiency.

Propeller propulsion and pump-jet propulsion have one thing in common in terms of installation and deployment: they are all deployed and installed on the stern of the ship, and all cannot be deployed and installed in other locations on the ship.

Due to the large radial size of the propeller blades, only the stern of the ship can provide suitable installation space. Further, in order to make full use of the propeller to push the water flow to obtain the maximum thrust, the propeller can only be deployed and installed in the stern of the ship.

The basic structure of the pump jet propulsion device is a straight pipe connected at both ends of a bent pipe, of which the straight pipe takes on the water intake function and the other straight pipe takes on the water spray function. As the core component of the pump-the impeller, it is deployed and installed in the water spray pipe. , And input driving force from an external power device through a shaft passing through the shoulder of the elbow. In order to minimize the pipe damage of the pump jet propulsion device when the working water flows through the pipeline, the total length of the pipeline is as short as possible; and taking into account the consideration of making full use of the pump jet propulsion to obtain the maximum thrust, the pump jet propulsion device can also only choose ships The stern is deployed and installed, so it is required that the water inlet of the pump-jet propulsion device and the water nozzle are arranged close to each other. At the same time, taking into account the convenience of its driving force input, the water inlet of the pump-jet propulsion device can only be deployed in the only place for ships. The bottom of the stern of a ship.

Propeller working water flow movement mode: When the propeller is rotating, a negative pressure area is created at the water-facing end of the blade. Under the action of negative pressure, the water flow enters the blade from the water-facing side of the blade, and is discharged from the back water end of the blade to form a propulsion after being energized by the blade. Water flow, the propeller working water flow movement mode belongs to the straight-in and straight-discharge mode. However, because the propeller is deployed and installed on the stern of the ship, the hull structure at a certain distance in front of the propeller blocks the straight path of the water flow of the propeller, which determines that the water flow through the blades can only be maintained from the bottom of the stern and the stern when the propeller is working. The lateral water inflow on both sides is continuously replenished.

The working water flow movement mode of the pump-jet propulsion device: water is fed in from the water inlet pipe, and the impeller of the pump is energized and sprayed out from the water pipe at high speed to form a propelling water flow. The working water flow inevitably flows through the elbow part, so the inlet and outlet water flows of the pump-jet propulsion device are not collinear, that is, it does not constitute a straight-in and straight-discharge mode. According to the working mode of the pump jet propulsion device, the more vivid name of the pump jet propulsion device is the curved suction jet propulsion device.

Whether it is a propeller propulsion device or a pump-jet propulsion device, their structure or working mechanism can only be limited to the deployment and installation of the stern of the ship. For the propeller propulsion device, the limitation of this deployment device causes the propeller working water flow to be maintained only by the bottom of the stern of the ship and the lateral water inflow on both sides of the stern; for the pump-jet propulsion device, this The limitation of the deployment device leads to the maintenance of the working water flow of the pump jet propulsion can only rely on a single water inflow from the bottom of the stern of the ship.

Such a water intake mode is not only unfavorable to the improvement of ship speed and energy efficiency, but will cause the ship speed and energy efficiency to decrease, indicating that the ship stern deployment and installation mode of the propulsion device is a defective and backward deployment and installation mode.

Why the stern deployment and installation mode of the propulsion device is a defective and backward deployment and installation mode? We can help understand through the analysis of the following hypothetical propulsion devices and hypothetical deployment and installation modes.

Assuming there is such a propulsion device, for the convenience of understanding, the propulsion device can be imagined as a straight cylindrical device body, and the pipe damage when the water flows in the cylinder body is ignored, that is, it can be set to any length. The front port of the straight cylinder is the water inlet, and the back port is the water jet. A working water flow energizing device is deployed inside the cylinder. The working water flows from the water inlet and is energized by the internal energizing device, and then sprays out from the water jet at high speed. Form a propelling water flow. Since the water inlet and the spray water of its working water flow are in a straight line, it has the aforementioned so-called straight-in and straight-discharge mode, which can be referred to as a direct-suction spraying device or an axial-flowing spraying device in comparison with the curved suction spraying of a pump-jet propulsion device. .

It is also assumed that one or more axial flow jet propulsion devices are deployed and installed on the bottom of the ship, and the water inlet is deployed and installed on the bow of the bottom of the ship; the water jet is deployed and installed on the stern of the ship.

How does this propulsion device and the deployment mode of such a propulsion device compare with the deployment and installation mode of the propeller propulsion device, pump-jet propulsion device, and the ship stern of the propulsion device? What kind of new propulsion effect will the ship obtain from this?

Water is a substance. Before the water body in front of the axial flow jet propulsion device is sucked in, the water can be regarded as an object placed at the front end of the water inlet of the axial flow jet propulsion device.

According to Newton's first law (law of inertia): "Any object remains stationary or in a state of linear motion at a uniform speed until it is forced to change this state by the force of other objects." Knowing: the axial jet propulsion device will be located in the front The inhalation of water into the water inlet is to change the state of motion of the water in front of the ship, and it is necessary to apply sufficient force to them by the axial flow jet to suck them in. In order to emphasize the water intake mode of this new ship propulsion device, it is specifically called the water-inflow mode.

According to Newton’s third law (law of force and reaction), "the force and reaction force between two objects are on the same straight line, equal in magnitude and opposite in direction." When the water is sucked into the water inlet, the axial flow thruster will be applied to the axial flow thruster "on the same straight line, the same magnitude, opposite direction" reaction force, that is to form the same magnitude of reverse pulling force on the axial flow thruster . Moreover, the higher the ship speed means that the speed at which the propulsion device sucks the front water body must also be higher, that is, the suction force acting on the front water body must be increased, and the pulling force on the axial flow thruster will of course increase accordingly.

Since the axial flow thruster is integrated with the ship, this force is finally transformed into a pulling force on the ship's navigation. That is: how much force it takes for the axial jet thruster to suck in the water ahead, the ship can obtain the same amount of pulling force given to the ship by the water body in front of the ship.

The magnitude of the pulling force obeys Newton's second law and can be calculated by F=ma, where m is the mass value of the moving body (water flow), and a is the motion acceleration value of the water flow.

Aside from rigorous and precise theoretical calculations, only simple and rough methods are used to approximate the magnitude of this force. Assuming that the diameter of the water inlet of the axial flow jet is 1m, the water inlet area can reach 3.14m ² , when the water flow speed of the axial flow jet reaches 10m/s, the working water flow entering the axial flow jet within 1s can be calculated The value of m is 31.4t; assuming that the acceleration of the working water flow of this mass into the axial flow jet is 10m/s ² , it can be seen that when the axial flow jet pushes with ^{an acceleration of 10m/s 2} the suction mass reaches 31.4t/s. The pulling force of the water flow can reach more than 300 tons. This is only the pulling force contributed by an axial flow jet propulsion device, which shows that the axial flow jet propulsion device has a great contribution to the ship's navigation by the deployment and installation mode of the ship's bow facing water.

The direction of the pulling force is the same as that of the ship’s advancing direction, which constitutes a pulling effect on the ship’s advancement. It combines with the propulsion force obtained by the propulsion water jet at the rear end of the axial jet propulsion device to form a combined force for the ship’s advancement. The forward power is doubled.

In particular, the pulling force is generated as long as the axial flow jet propulsion device is in the propulsion state, which is a derivative force of the axial flow jet propulsion device working in the propulsion state, and is a force that promotes the ship's navigation without additional energy consumption of the ship. force. Compared with propeller propulsion or pump jet propulsion, it is a form of ship propulsion that cannot be obtained by propeller propulsion or pump jet propulsion.

Further analysis of the propulsion device as the axial flow jet propulsion device and the implementation of the above-mentioned water-inflow deployment and installation mode of the ship’s navigation resistance can be found, as the ship’s inherent and the absolute majority of the ship’s navigation resistance, the water-heading resistance, wave-making resistance and The viscous pressure resistance will change greatly, specifically:

Due to the use of axial jet propulsion devices and the deployment and installation of axial jet propulsion devices into the bow water intake and direct suction jet propulsion modes, and the specific deployment and installation quantity of the axial jet propulsion devices are determined by the ship’s bow, the ship’s bow constitutes a barrier. Part or most of the water body of the water wall is transformed into a working water body that is sucked by the axial flow jet propulsion device from the water inlet provided at the bow of the ship, and after being energized, it is ejected from the stern of the ship to become the part of the propelling water body and the resistance to sailing against the water. Or most of them lose their existence conditions and disappear; the bow waves of sailing ships also lose their forming conditions, and part or most of the ship’s wave resistance will also disappear; also because the ship passes through the water and creates a regional vacuum at the rear of the ship. Since the bow of the ship becomes the continuous filling of the propelling water body, the pressure difference between the bow and stern of the ship will be greatly reduced due to the regional vacuum at the rear of the ship, which means that part or most of the viscous pressure resistance will disappear.

The above-mentioned axial jet propulsion device and water-inlet deployment installation mode are also applicable to submarine devices such as submarines (except for some submarine devices that use small and decentralized propeller propulsion devices). The difference between submarine devices and ships is: submarine devices Wrapped by water, there is no wave-making phenomenon and wave-making resistance; the water intake mode varies according to the deployment and installation position of the propulsion device. To grasp the difference between the submersible device and the ship, you can refer to the influence of the above-mentioned axial jet propulsion device and the water-inlet deployment installation mode on the ship's resistance and propulsion mode, and also analyze and understand the axial flow jet propulsion device and the water-inlet deployment installation mode. The value effect on the navigation of the submarine device.

On the other hand, the propeller propulsion mode, because it is deployed and installed in the stern of the ship, the mode is taken from the bottom of the stern of the ship and the lateral water inflow on both sides of the stern. It can be seen from the force analysis that the propeller propulsion device’s water intake pull force obtained by the lateral water intake on both sides of the stern also exists, but their directions are opposite to each other, and they are perpendicular to the navigation direction of the ship. Contribution; and the propeller propulsion device obtains the water intake pull force from the bottom of the stern, and its direction is also perpendicular to the ship’s navigation direction. The direction points to the depth of the water body, which is equivalent to increasing the weight of the ship, resulting in an increase in the ship's draught, and the increase in the ship's draught will increase its navigational resistance. This means that the effective thrust of the ship will be reduced, which will reduce the speed and energy efficiency of the ship.

On the other hand, because the propeller is deployed and installed on the stern of the ship and the bottom direction of the stern and the lateral water inflow mode on both sides of the stern, it means that a large amount of working water body needs to be sucked from the rear of the ship when the propeller is propelled, and it is manufactured at the rear of the ship. Regional vacuum, which is superimposed on the regional vacuum created in the rear of the ship as the ship passes through the water body, intensifies the regional vacuum range or degree of vacuum behind the ship, resulting in high bow and stern low pressure caused by the regional vacuum between the fore and aft of the ship. The difference is more prominent, and the viscous pressure resistance caused by the regional vacuum will further increase, increase the effective thrust consumption of the ship, and reduce the ship's speed and energy efficiency.

In the same way, the pump-jet propulsion mode is analyzed. Because it is deployed and installed in the stern of the ship, the water intake is a single stern bottom water intake mode, and its influence and effect on the ship’s navigation is similar to the propeller propulsion mode. The result of the analysis of the force is also: the ship’s sailing resistance is increased, the ship’s effective thrust is reduced, and the ship’s speed and energy efficiency are reduced.

Further analysis, the pump jet propulsion implements the curved suction jet push mode and because the pump jet propulsion device is deployed and installed inside the ship, the working water flow sucked by the pump jet propulsion device needs to rise a height before it can enter the spray pipe to obtain the impeller's energizing effect. The working water that stays in the pump-jet propulsion pipeline during the period from the water inlet to the spray-out from the water jet essentially becomes a part of the ship’s weight. The weight gain of the ship caused by the internal working water flow should not be underestimated. It will lead to an increase in the ship's own weight and an increase in the ship's draught, which will further lead to an increase in the ship's sailing resistance.

Further analysis, the working water flow inside the pump jet propulsion pipeline needs to change the direction of the flow through the elbow, which is easy to form turbulence or eddy current loss at the inner bending part of the elbow, which is also a factor that weakens the total thrust output of the pump jet propulsion, and will also cause ships. Speed and energy efficiency are reduced.

In fact, in addition to the above-mentioned shortcomings in the propeller propulsion mode and pump-jet propulsion mode, there are also many other application shortcomings. The specific manifestations are as follows:

For propeller propulsion:

1. The propeller power transmission system and structure are generally complex. The propeller power transmission system and structure of large ships, especially large surface ships such as aircraft carriers, can be described as very complicated, requiring a considerable amount of ship storage capacity, resulting in a waste of effective storage capacity of the ship;

2. The manufacture of large, especially super-large propellers requires a large amount of special materials and special processing equipment to support, which significantly increases manufacturing difficulty and manufacturing costs, and is not easy to assemble, disassemble and maintain;

3. The self-weight of large, especially super large propellers, the weight of a single super large propeller can even reach hundreds of tons, increasing the ship's weight and sailing resistance;

4. Large, especially super-large propellers are prone to cavitation when working, causing damage to the propeller blades, resulting in reduced propulsion efficiency and unnecessary noise;

5. For large, especially super large propellers, when the ship is under no-load or light-load navigation, the blades will grow out of the water surface, resulting in periodic force unevenness of the propeller blades during rotating work;

6. Propellers, especially large and super large propellers, are prone to mechanical damage to aquatic organisms;

7. The risk of entanglement of the propeller is high.

For pump jet propulsion:

1. The bottom-direction water inflow is implemented by pump jet propulsion, and its water inflow efficiency is not as high as that of water inflow;

2. Pump jet propulsion implements bottom water inflow. When navigating in waters with a lot of weeds or debris, the water inlet is easily blocked and affects the water intake, resulting in lower propulsion efficiency or even failure;

3. Pump jet propulsion implements bottom-injection water, shallow water navigation is easy to suck in the gravel and gravel in the water area, causing mechanical damage to the propulsion device;

4. The deployment and installation of the pump jet propulsion device needs to occupy a certain storage capacity in the stern of the ship.

Through the work of the set propulsion device, the ship obtains the driving force that supports the ship to overcome the sailing resistance and sail forward. As the sailing speed of the ship increases, the sailing resistance of the ship increases rapidly in a quadratic ratio to the speed. When the sailing speed increases, it increases. When the total resistance of the ship’s navigation is equal to the propelling force possessed by the ship, the ship is stable at that speed and sails at a constant speed. If the ship’s propulsive force is increased to be greater than the total resistance of the ship at the speed, the ship will accelerate to sail to obtain a higher sailing speed. When the total resistance of the ship increased due to the further increase in speed is equal to the increased propulsion force of the ship , The ship stabilizes at the new higher speed and sails at a constant speed.

Ship propulsion depends on the energy conversion of the ship's power system. Increasing the propulsion can increase the speed and increase the water range of the ship. However, increasing the propulsion means that the increased energy consumption of the ship will inevitably increase the cost of the ship's navigation. When the economic benefits that can be achieved by the ship at high speed are not as high as the high cost caused by excessive fuel consumption of the ship, the high speed of the ship is not worth the loss, which means that the energy efficiency of the ship is low, which is also the reason why the ship speed and energy efficiency are generally low today. one.

After the ship type and ship power system including the propulsion device are determined, the ship's speed and energy efficiency are determined by the combined action of the ship's sailing resistance and the ship's propulsion, reducing the ship's sailing resistance and improving the ship's speed and energy efficiency.

The previous analysis has shown that the use of axial jet propulsion devices and the deployment and installation of axial jet propulsion devices into the bow water intake and direct suction jet propulsion modes will result in a significant reduction in the ship’s sailing resistance and the output power of the ship’s power system. Under the same conditions, it helps to greatly increase the speed and energy efficiency of ships. It has an absolute competitive advantage over propeller propulsion and pump jet propulsion.

In particular, this kind of axial flow jet propulsion device and the deployment and installation of the axial flow jet propulsion device into the bow water inflow and direct suction jet propulsion mode allow the promotion and application to any ship including submersible devices, so it also contributes to the overall Solving the problem of generally low ship speed and energy efficiency, ushering in the era of global high speed.

What needs to be clear is that the current era is still an era of generally low speed, and sufficient technical conditions have not been prepared for the advent of the era of generally high speed. In particular, there is a lack of general promotion of sufficient and sufficient navigation safety conditions for high-speed sailing ships. Relying solely on the deployment and installation of the axial flow jet propulsion device and the axial flow jet propulsion device into the bow water inflow and the direct suction jet propulsion mode cannot support the realization of the universal high speed era. The specific manifestations are as follows:

Based on the consideration of ship navigation safety, the current speed of many ships is artificially lowered or restricted, which is a forced low speed.

The opening of the era of generally high speeds under the existing technical conditions will cause major chaos in global shipping and easily lead to major navigation safety risks. If there are no breakthroughs in the following three technologies, it will be difficult to truly realize the era of generally high speeds of ships. specifically is:

1. The problem of ship's rapid change of direction

Most ships nowadays use stern and rudder to change direction. The stern and rudder change has obvious defects, which is not conducive to the flexible change of direction and collision avoidance of high-speed ships. The potential safety hazards are prominent and it is difficult to support general high-speed navigation. the reason is:

1. The steering torque of the ship's stern and rudder steering method is small, which supports the difficulty of the ship's rapid steering change, and it is inconvenient for the ship to make emergency avoidance.

The stern rudder of a ship is generally set as a single rudder and is deployed and installed on the center line of the stern of the ship. The direction changing force obtained by the deflection of the rudder blade is very short relative to the lever arm of the ship's central axis, and the resulting direction changing moment is small; that is, the double rudder method is adopted. Deployment, the two rudders are deployed and installed off the center line of the stern of the ship. The direction change force obtained by the deflection of the two rudder and rudder blades has increased relative to the length of the lever arm of the ship's central axis, and the resulting direction change torque follows an increase, but the increase is still limited , The rudder effect is still not obvious.

2. The bow change response of the ship's stern and rudder direction change mode is slow, which is inconvenient for the ship's emergency avoidance.

The distance between the bow and the stern rudder of the ship is close to the length of the ship. The change of direction of the stern rudder reflects that it takes a process to change the direction of the bow and cannot respond quickly. This is especially true for large ships and long and narrow ships. Turning a turn requires a large turning radius, which is not convenient for ships to make emergency evasion and is not suitable for the era of high speed.

The existing technology has developed the rapid change of ship's direction using the pod propeller and rudder, and the setting of a specialized bow change propulsion device at the bulbous bow of the ship. Due to the implementation of the coordinated change of the ship's bow and stern, this technology can significantly increase the speed of the ship's response to the change of direction and support the ship's emergency avoidance. However, for ships without a bulbous bow, this method of ship direction change will greatly reduce the response speed of the ship’s direction change; when the ship is sailing but does not change the direction of the ship, the direction-changing thruster installed at the bulbous bow is installed The formation of vortex, turbulence, and turbulence at the structure will increase the resistance of the ship's navigation; the process of changing direction will increase the additional energy consumption. Therefore, it still cannot be regarded as an ideal ship redirection technology.

2. Ship's rapid deceleration/brake problem

Due to the ship’s own inertia and the ship’s carrier being fluid water, the ship in navigation stops its propellers, and the ship will still glide forward for a considerable distance. The speed and distance of the ship taxiing forward, as well as the destructive force contained therein, are determined by the ship's own inertia and the initial speed when it stops. The greater the total mass of the ship itself, including its loaded materials, the higher the initial speed, the greater the forward glide speed and glide distance, and the greater the destructive power contained. Today's ships generally do not have rapid deceleration/brake support technology. The speed reduction/brake of sailing ships cannot be achieved. In the general high-speed environment, especially in the case of high-density high-speed sailing ships, there is a great collision safety risk, and it is obviously not suitable for the high-speed era.

3. The threat of surge from high-speed and large-volume ships

When a high-speed and large-volume ship is traveling in a narrow waterway, such as an inland waterway, the large volume of water discharged by the passing high-speed and large-volume ship is too late to be reduced and is forced to transport to both sides of the ship at high speed, thus forming a huge surge. This surge will have a strong impact on adjacent ships or shore-lifting facilities, and may cause tsunami-like damage.

Fourth, the problem of breaking through the limitations of ships obtaining super propulsion

Ships hope to obtain ultra-high speeds, and their super propulsion is a fundamental condition. The existing ship propulsion technology, whether it is propeller propulsion or pump-jet propulsion technology, is subject to the space constraints of the ship’s stern that can only be deployed and installed, as well as their own impact on the working water flow. The empowerment model is limited, and it is difficult to realize the desire to obtain super propulsion.

In summary, the axial flow jet propulsion device and the axial flow jet propulsion device are deployed and installed into the bow water intake and direct suction jet propulsion modes as technological innovations, and their popularization and application are expected to promote the realization of a generally high speed era. The realization of the era of universal high speed will create incalculable economic and social value for the world. Because:

Water transportation is a mode of transportation that uses ships as vehicles. It uses natural rivers, lakes, and seas as roads and also includes very few artificial waterways. Unlike land transportation, which requires huge investment in the construction and maintenance of roads (high-speed railways and expressways), it does not occupy or occupy less land; , Compared with the land transportation mode with railway as the main body, the biggest advantage lies in: heavy load, low energy consumption and low transportation cost.

The generally low speed of ships nowadays leads to a significant gap in the length of land transportation between water transportation, trains and automobiles, and it is even less comparable to air transportation. Water transport has the advantages of low transportation costs and can save huge investment in the construction and maintenance of transportation roads. In today's society where high efficiency is generally pursued, water transportation shows a clear competitive disadvantage to land transportation in terms of transportation timeliness, especially inland water. It is outstanding in transportation and internal water passenger transportation.

Take my country as an example. Nowadays, except for the maintenance of water transportation in a few golden mainstream waterways such as the Yangtze River, Pearl River and Canals, most inland river freight transportation is rare, and inland passenger transportation is almost extinct. Take the Xiangjiang and Liuyang sections of Changsha as an example: Nowadays, the Xiangjiang River, which used to be "struggling for the flow of hundreds of rivers," only exists in the memory of the past, and the Liuyang River has become a quiet river completely; There is no trace of the prosperous wharf culture, and only a depression can be used to describe the prevailing inland water transport.

And the total annual transportation volume of a developed inland waterway can be equal to the total annual transportation volume of dozens of railways. The reality that many inland waterway transportations are actually abandoned due to the generally low speed is indeed a huge awkwardness in the productivity of modern society. Waste.

Although the low transportation cost of ocean freight and the accessibility of sea routes give ocean transportation an absolute advantage over any modern form of high-speed transportation and the prosperity of the current maritime industry is supported by the development of the world economy, its long transportation cycle is still a society that the world is eager to solve. And economic pain points. The long-distance maritime passenger transport industry nowadays has almost disappeared in addition to being used for marine sightseeing, which shows that today’s maritime transport industry also has a huge waste of modern social productivity.

Affected by the world’s natural and geographical factors of three mountains, six rivers and one field, as well as the low-cost advantages of water transportation, water transportation has the disadvantage of a long transportation cycle, but it still does not lose one of the most important means of transportation that mankind depends on. Today’s global cargo More than 90% of the total ton-kilometer capacity is carried out by water, especially by sea.

Since water transportation is responsible for such a large part of the total global social cargo transportation, assuming that the speed of today's ships is generally doubled or even higher through technological progress, and the energy efficiency of navigating ships is also improved, can you imagine how much it will create for the future world? Economic and social contribution!

Water transportation is not only a problem of passengers and cargo. Fisheries, especially deep-sea fisheries, also have the problem of generally low speed. For example, when marine fishing vessels encounter severe ocean climate warnings, ocean-going fishing vessels in operation need to return to the port early for safety. , A waste of time, missed fish floods, and a lot of empty fuel consumption, causing losses to the fishery economy.

Speed is an important indicator of marine military power. The advent of the era of generally high speed will also affect revolutionary changes in marine military technology. For example, if the instantaneous speed of an aircraft carrier can reach or exceed 100 knots, it may cause major changes in the take-off method of carrier-based aircraft and further lead to the structure of the aircraft carrier. Changes.

Since water transport takes on most of the world’s transportation volume, the total amount of energy consumed during transportation is staggering, and the damage to the atmosphere caused by its release of combustion exhaust gas is equally astonishing. The substantial contribution that can be made is also incalculable.

The use of direct suction and injection propulsion devices and the implementation of direct suction and injection propulsion deployment and installation mode for forward water inflow can achieve a significant improvement in the energy efficiency of ships' navigation. Its promotion and application can promote the global water transport industry to greatly improve the energy-saving and emission-reduction capabilities. Make beneficial contributions to respond to and improve global climate deterioration.

It can be expected that the technical research, promotion and application of the new high-speed, high-efficiency and safe water jet propulsion methods, system devices and applications of ships will make significant technical, social and economic contributions to the international society in the future.

When the fast response steering method of the watercraft is implemented, the watercraft uses the vertical midship plane as the symmetry plane, and symmetrically deploys the direct suction jet with both propulsion and direction adjustment on the bow or near the bow adjacent to the inboard on both sides. Propelled water inlets, and direct suction jet nozzles with both propulsion and direction adjustment are deployed on the stern or near the stern adjacent to the inner sides of both sides, and make the direct suction with both propulsion and direction adjustment. The water inlet of the jet pusher enters the laterally or laterally obliquely from the outside of the sideboard, so that the water jet of the direct suction jet, which has both propulsion and direction adjustment, sprays water in the lateral or lateral oblique direction toward the outside of the sideboard.

The present invention also provides a new type of rapid and efficient deceleration/brake/direction processing method for ships, which includes: taking the longitudinal axis of the ship as the symmetry axis, and installing at least one set of ship water resistance devices, wind resistance plates or axial jet thrusters on the ship.

Specifically, as shown in Figures 49-55, the ship can deploy the wind resistance plate 11, when the wind resistance plate 11 is in the open state, the ship obtains resistance, so as to realize the ship's deceleration, braking or direction change function; in particular, when the wind resistance Part of the resistance plate of the plate 11 is located below the waterline of the ship, and the resistance plate is in a water resistance/wind resistance shared mode.

As shown in Figures 56-57, the ship 2 can also deploy the ship water resistance device 10 and the wind resistance plate 11 at the same time; when the ship water resistance device 10 or the wind resistance plate 11 is in an open state, the ship 2 obtains resistance, thereby realizing the ship’s Decelerate, brake or change direction function; Ship 2 is equipped with a resistance plate above the waterline and a resistance plate below the water. This mode is the independent deployment mode of the water and wind resistance plates.

The ship’s water resistance device 10 is deployed on both sides of the ship, and one of the water resistance speed plates set on the side of the ship is opened to be in a working state. This side water resistance speed brake can obtain the longitudinal axis of the ship’s excessive center of gravity. The rotation torque enables the ship to obtain a deflection moment around the longitudinal axis of the center of gravity, and deflect towards the side where the water resistance speed plate is opened, so as to change the direction of the ship’s navigation; because the water resistance speed plate installed on the side of the ship has a special effect on the ship’s passing The longitudinal axis of the center of gravity has a larger torsion arm, and the water resistance per unit area available for the longitudinal axis of the ship’s over-center of gravity has a greater torsion torque than the water resistance speed plate installed at the bottom of the ship, which is in a braking state. The water-resistance retarder at the bottom of the ship, which is in a braking state, has a greater effect on the ship's steering efficiency, and it exceeds the steering efficiency per unit area provided by the ship's conventional stern rudder by several times.

The ship deploys and installs the wind resistance plate 11 on both sides of the ship. When one of the air resistance speed plates set on the side of the ship is opened, it will be adjusted to the working state. The side air resistance speed brakes can obtain the rotation of the longitudinal axis of the ship’s excessive center of gravity. Torque enables the ship to obtain a deflection moment around the longitudinal axis of the center of gravity and deflect towards the side where the air-resistance speed brake is open to realize the change of the ship’s navigation; because the air-resistance speed brake installed on the side of the ship is aimed at the ship’s excessive center of gravity The longitudinal axis has a larger torsion arm, and the air resistance per unit area can be obtained for the ship’s over-center of gravity. The longitudinal axis has a greater torsion torque than the air-resistance brake plate at the bottom of the ship, which is in a braking state. The air-resistance retarder at the bottom of the brake working state has a greater effect on the direction of the ship, and it is several times better than the steering efficiency per unit area provided by the ship's conventional stern rudder.

When the longitudinal dimension of the water-resistance speed brake/air-resistance speed brake is large, consider the rigidity of the water-resistance speed brake/air-resistance speed brake and the flexibility of operation, as well as the strength of specific deceleration or steering requirements (for example, only a slight deceleration is required. , Or slightly change direction), and further set the water resistance speed brake/air resistance speed brake from the length direction to a multi-stage combined structure, so that each stage can be controlled independently, or each stage can be controlled in a unified manner. For example, when the direction is slightly adjusted, Only one of the segments can be controlled. When emergency steering is needed, each segment can be linked to control the unified opening action.

It should be noted that the ship deploys a single deployment mode or multiple combined deployment modes of the ship water resistance device 10, the wind resistance plate 11 or the axial jet thrust device; according to actual needs, the ship can deploy the ship water resistance device 10, the wind resistance plate 11 and The arrangement of the axial flow jet propulsion device in other positions also belongs to the protection scope of the present invention.

The invention provides a new fast and efficient wave-making suppression processing method for ships, in which inconsistent supporting ribs are arranged at the bottom of the sideboard.

Furthermore, water jets for suppressing wave-making axial flow are arranged at the interval fractures of the discontinuous supporting ribs.

Specifically, as shown in Figures 98-103, the ship 2 is provided with discontinuous support ribs 6 at the bottom of the side line; the partition of the discontinuous support ribs is set as the wave-making water inlet, and the wave-making water inlet is provided with an axial jet thruster. Device 1; the water inlet of the axial flow jet thrust device 1 faces the interval fracture of the discontinuous supporting edge. Ship 2 adopts this design to realize wave making suppression.

Specifically, as shown in Figs. 104-106, the ship 2 is equipped with a bilateral symmetrical deployment axial flow jet propulsion device 1 with both wave suppression and direction adjustment functions. The ship 2 is provided with a wave-making and steering water inlet 154 on both sides of the bow or near the bow.

The principle of the high-efficiency wave-making suppression treatment method for ships of the present invention is: below the sideboard waterline of the ship, a wave-making water inlet with an opening facing the direction of the ship’s advancing direction is provided (or a part of the wave-making water inlet is allowed to be set above the waterline), The outlet of the Xingbo water inlet is located on the inside of the ship’s side and is connected to the axial jet propulsion device. The wave making water generated on the sideboard when the ship is sailing is sucked by the axial jet propulsion device through the Xingbo water inlet and then ejected from the stern of the ship. , So that the wave-making current on the side of the ship loses the conditions for forming, and the original wave-making current is transformed into the propulsive force that pushes and pulls the ship forward, and the wave-making current is transformed into the ship propulsion current, which can reduce a certain amount of ship bottom due to the ship. The formed vacuum can reduce the generation of viscous pressure resistance, and promote the increase of ship speed from three aspects (injection, resistance reduction and wave-making current pull). Compared with the stern propulsion of a ship, the only thing that must depend on the consumption of fuel is to increase the speed of the ship with lower energy consumption.

It should be noted that the other function of the wave-making suppression processing device is that when the ship is sailing at high speed, the wave-making flow is transferred to the stern of the ship due to the wave-making suppression processing device, so that the ship will not form a large ship. Wave-making waves impact adjacent ships; when the ship is traveling in a relatively narrow inland waterway, it can avoid the impact of large wave-making waves from high-speed ships on both sides of the channel.

The new type of ship hydro-lifting method provided by the present invention is provided with a fixed or accommodating hydro-lift structure at the bottom of the ship, in particular, the hydro-lift structure is installed before the axial jet propulsion nozzle on the bottom of the ship. When the ship is sailing at high speed, the lift of the water on the water-lifting wing is used to lift the ship, reduce the ship's draught depth, reduce the ship's sailing resistance, and increase the ship's speed.

Specifically, as shown in Figures 107-108, the bottom of the ship is provided with a recessed structure 8, the front end of the recessed structure 8 is a groove water inlet 801, and the water inlet of the axial flow jet pushing device 1 faces the groove water inlet 801 , A water-lifting wing 20 is installed at the bottom of the ship, and the water-lifting wing 20 is located below the groove water inlet 801; the water flows through the water-lifting wing 20 from the groove water inlet 801 into the axial flow jet thrust device 1. The principle of hydro-lifting wing is the same as the principle of obtaining lift of an airplane wing.

It should be noted that when the ship sails at high speed, the lift effect of the lift wing can be manifested. When the ship sails at low speed, the resistance must be the main factor. In view of this, consider setting the lift wing into a retractable structure and only lower it when the ship is sailing at high speed. Use; secondly, by borrowing the drag effect of the lifting wing, the lifting wing can be further set into a reversible structure. When the ship needs to brake quickly, the lifting wing can be released and turned over to provide braking effect.

The invention also provides a fly-by-wire navigation control technology applied to ships.
