In the research of the laboratory, the boat can be enlarged, Zhao Xin at the beginning, choose a small boat of less than 100 tons, the purpose is also very simple, is to practice, from a small boat to a large ship, Zhao Xin of course knows, the small one is out, the big one is not far away, in his opinion everything is no problem, a little digest this result, should be able to make a large number of ships.

Zhao Xin still underestimated the technical difficulty of the ship, unceremoniously said, the ship concentrated several aspects of science and technology, the ship is one, the steam engine, and some other small aspects, integrated together, this is a system engineering, this systematic engineering, in later generations, is a very simple, but in this era, that is the embodiment of all the systems gathered together, it contains the highest scientific and technological content in the entire Dinghai.

Zhao Xin has never underestimated the systematic engineering of the steamship, and even paid attention to it personally, in the study of the steamship, it was a little detour, and after he was alertly discovered, it was revised back, it stands to reason that according to the development of history, it should be a smooth road, but now, it is still progressing very slowly.

100 tons of small ships, has been launched, this through the iron rib summed up the lessons, and formed a simple density ratio, the results of the experiment is not very good, stability and reliability, or relatively poor, in a calm place is a little easier, once encountered wind and waves, it is easy to capsize.

Zhao Xin also knows where the reason is, just like the previous problem, it is still a density control that is not in place, and there are also huge problems in the center of gravity, which are all problems that the ship must encounter.

The ship is made of steel, which is heavier than water, and this material not only has design problems, but also has the problem of navigating in the ocean.

On wooden ships, the pool experiment is a very important method, which can provide some evidence for the experimental ships, but the basis of this is that wood is lighter than water, as long as it is slightly adjusted, almost according to Zhao Xin's drawing, the effect can be achieved, and the center of gravity and shape are based on the European hundreds of years, and finally summarized.

However, the ship is different, the shape is very important, but the internal layout is more important, the density of steel is different, the cabin is different, and there is no way to arrange the center of gravity and density simply by drawing the shape, which is the root of the problem.

To solve it, there are two ways, one is to make a fully simulated pool experiment, set the current level of science and technology of the navy, and only be able to complete the pool experiment on the static top, the effect of this experiment looks good, but this is a static experiment.

The pool experiment is very simple, get a model boat, and then follow the data, but the experiment of the pool cannot simulate every environment in the sea, perhaps in later generations, with the application of computers, as well as the continuous progress of various simulation methods, so that the pool experiment has reached a certain accuracy, but under the current scientific and technological conditions, it is even said that the depth and breadth of the navy's knowledge mastery is not at all.

The pool experiment is not good, or rather, a complete system has not yet been formed, so that the pool experiment can simulate the real real environment, which is too difficult without a computer.

In fact, for such pool training, Zhao Xin just thinks about it, that is under the premise of computer control, it is also necessary to record the characteristics of many oceans, and the study of various fluid mechanics has also entered a very profound level.

Computer, that is a very important development direction in the future, it can be said unceremoniously, the card system, for the development of computers, has natural advantages, semiconductors, itself is a matter of probability, the initial development of things, the reason for the high price, is that the yield rate is not high.

The card system, which can copy the best semiconductors, as long as the direction is correct, you can keep leaping forward through the card system, with Zhao Xin, a traverser, at least in the first decade of the 21st century, or even most of the direction of the second is no problem.

It sounds very beautiful, but in fact, it is not so beautiful, even the most ordinary machinery, I have not figured it out, there is no complete system, and even now the power is up, just entering the steam engine, not to mention the internal combustion engine and electricity, the computer is something out of reach.

Since computers are so far away, it is impossible to experiment with pools, so only the second one can be used.

After all, computers were only developed during World War II, and even in the seventies and eighties of the 20th century, they were developed on a large scale.

Quite simply, that is, through experience, theory, and even sea trials, gradually accumulate experience, and finally form a mature set of programs.

This is a very commonly used plan, but at the beginning, Zhao Xin would rather take shortcuts than choose the root cause, this plan, the Dinghai has not accumulated at all, if you want to follow this, you have to start from scratch.

This is the most lacking in the navy, every project of the navy, is a leapfrog development, sometimes, new equipment, has not yet touched the more proficient premise, there is already better equipment appeared, this is a lot less accumulation of the process, this process, for simple, or luck research projects, there is no problem, but for ships like this, the integration of a lot of science and technology projects, is a natural problem, the bottleneck is here.

Zhao Xin has pulled them into the normal track, from this problem, he has done what he can do, this is no longer a problem of development direction, this should be a matter of time, develop in this direction, solve the problem step by step, accumulate experience through sea trials, figure out the contrast between density and sea conditions, this needs to be accumulated.

Historically, Europe was able to quickly enter the age of ships from the era of sailing ships and iron ribs, and the reason is that hundreds of years of navigation, accumulated things, and a hundred years of navy, this cannot be overstated.

The navy was established later than the Ding Navy, and even from the original Chinese-style sailing ships, Spanish galleons to clippers, during which not much time passed.

It is equivalent to saying that a kind of sailboat, without the premise of eating thoroughly, is replaced with more advanced, which reduces the process of accumulation.

If it weren't for the exploration of North America, from the sea route, all the way across the Pacific Ocean, with countless hardships and blood, this would have accumulated some experience, and even a small steamer, it would be impossible to talk about, let alone such a reluctant steamer.

Now, reluctantly, and forcibly with the iron ribs accumulated experience, next, has been along the right path of development, the next is the question of time, how to figure out this proportion under the real sea conditions, and at the same time the problem of this center of gravity, if these do not accumulate down, even if they can successfully make a suitable ship, in the future, once expanded, or under the premise of other uses, it is still blind.

Time can be saved, with the vision of future generations, it does not mean everything, unless, Zhao Xin can now get computer-aided design, and intelligent pools to get out, otherwise, it can only be accumulated.

Starting from scratch, this requires courage, especially for the Ding Navy, which has already completed a lot of preparations, and even when the drawings of 500 tons and 1,000 tons are drawn, they still need to start from scratch, which is equivalent to saying that everything before has been wasted.

But Zhao Xin's order, of course, is forbidden, and soon, including which iron-ribbed wooden ships, as well as these experimental ships, and even next, will start to build a series of ships, with only one use, non-stop sea experiments, accumulate a large amount of data, and find the key to solving the problem with the support of a large amount of data.

This is not the only problem of the ship, the reason why the ship is called a systematic project, it is a combination of many sub-projects, the focus and design of the problem, only one of them, the power system is the most critical.

Even the Dinghai Navy, in terms of steam power, has been running for many years, steam locomotives, has been popularized throughout the Dinghai Navy and the Northern Song Dynasty, and now has more than 3,000 steam locomotives of various types, which is very mature.

However, the steam engine pushes the train, and the steam engine pushes the ship, which are two different things, one is the propeller, which pushes the wheel, and the other is the propeller.

As long as it is iron, it fits the railroad well, and it is not a problem to move forward on land, but the propeller is different, which requires a power unit, and the reciprocating preaching also needs a transmission device, if the design is slightly wrong, it is easy to have problems.

In addition to the power plant and transmission device, the propeller is also an important problem, the propeller of later generations, are not directly forged and processed, after processing, must be processed according to a certain design, so as to reduce the resistance of water to the minimum.

But now, there is not even a qualified machine tool, let alone three or five axes and the like, it is almost impossible to complete the task, for the processing of the propeller, it is only a few different forms, cutting methods, reluctantly made a few, and selected the best one.

The problem of propellers, which is a problem to be considered in the future, can only be selected with CNC machine tools for surface processing methods, or according to the study of fluid mechanics, through calculation, find out the most reasonable method, and process it by manual method.

Don't underestimate the method of handwork, in a sense, manual is not necessarily weaker than machinery, the premise is that manual work must reach a certain level, for example, the former eighth-level worker.

At present, after many aspects of training and training, there are more than 1,000 eighth-level workers, the reason for which is, on the one hand, that the Northern Song Dynasty still has Chinese traditions, craftsmen are passed down from generation to generation, and there are some unique keys, on the other hand, some methods of refining the body may not make craftsmen become strong men or supermen, but it is certain that they are stronger than ordinary people.

Some unique exercises can increase stability, increase strength accuracy, and staying power, which are very important aspects for the eighth-level worker, and these are also the cornerstone of the entire Dinghai Navy.

The leapfrogging nature of the Dinghai Navy is too strong, from the handicraft industry, not even basic industry, to the construction of a huge scale of heavy industry at once, and there are many leaps in all aspects, and these leaps are not without hidden dangers, but there is no such outbreak as a steamship.

On the material, the Navy itself has a huge advantage, a bull vigorously, directly let the Navy explode in terms of materials, in addition to Zhao Xin's guidance, a variety of graphics, there is no problem with the design, the problem of processing is highlighted, the 1000 eight-level workers, can be said to be the treasure of the Navy, responsible for processing, are some important machines, and some grading of 7, 6 workers, these people, together to build the high-end processing of the Navy.

It's a pity that in how powerful the individual, or can not be compared with the whole, the construction of the great country in later generations, how many machine tools, some high-precision machine tools, their processing capacity, is above the workers, this can create scientific and technological innovation, but the 11th century Dinghai, is not capable of realizing.

Propeller, temporarily from several designs, choose the strongest driving force, all aspects of the standard is also the highest one, temporarily propeller and transmission system, can only be like this.

As for power, this is the key to a ship, and it stands to reason that this is the most high-end technology of the Navy, and there should be no problems, but it has problems.

The transplantation of the train to the ship is a very difficult thing in itself, the train and the ship, these are two systems, and the initial also took a lot of detours, and the center of gravity and density are different, that can be directly seen, if there is a problem, it can be adjusted directly, but the power is not visible.

The value of power, the ship that can be propelled, and what kind of speed it sails, no one knows, what Zhao Xin knows, is just the simplest kind of physical formula, similar to the ship, there is also a conversion formula between power and energy, speed, this is really beyond the scope of his understanding.

This made the power problem, in the beginning, was ignored, until there was a power problem, and at the same time, another ship that used auxiliary power, not all steel, but an iron-ribbed ship, when they kept recording data, suddenly found that they ran at a higher speed under the premise of using a relatively small steam engine.

At first, the researchers thought it was wrong, but through the comparison of the sextant, the whole data was correct, then, putting aside the influence of the wind, it was a headwind, all the sails landed, there was no influence of the wind, and there was such a high data, there was a problem in the middle.
