In the laboratory research, the ship can be enlarged, Zhao Xin began, choose a small boat below 100 tons, the purpose is also very simple, is to practice the hand, from the small boat to the change of the big ship, Zhao Xin certainly knows that the small out, the big is not far away, in his thinking that everything is no problem, a little digestion of this result, should be able to mass production of the ship.

Zhao Xin still somewhat underestimated the difficulty of the technical aspects of the ship, unceremoniously, the ship has 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 system engineering, in the future, is a very simple, but in this era, that is, all systems are concentrated together, it contains the highest content of the entire Navy.

Zhao Xin never had a small look at the ship's systematic engineering, and even personally concerned, in the study of the ship, is a little detour, after the discovery of his alert, and then modified back, according to the development of history, it should be a smooth road, but now, still progress is very slow.

100 tons of small ship, has been launched, this through the iron ribs to learn lessons, and the formation of a simple density ratio, the results of the experiment are not very good, stability and reliability, or relatively poor, in a calm place is better to do a little, once encountered the wind and waves, it is easy to overturn.

Zhao Xin also knows where the reason is, as with the previous problems, or a density control is not in place, in the center of gravity problem, there are huge problems, these are the ship must encounter the problem.

Steamship is the use of steel this heavier material than water, this material not only has the design above the problem, but also must sail in the sea, the future ship, the reason why in the high sea environment, can be smooth sailing, the entire center of gravity and density, is a key.

Above the wooden ship, the pool experiment is a very important method, which can provide certain support to the experimental ship, but the basis of this is that the wood is lighter than the water, as long as it is slightly adjusted, almost according to Zhao Xin's drawing, you can achieve the effect, that center of gravity and shape, according to Europe for hundreds of years, the final summary.

However, the ship is not the same, the shape is very important, but the internal layout is more important, the density of steel is different, the setting of the cabin is different, and there is no way to arrange the center of gravity and density, which is the root of the problem.

To solve this problem, there are two methods, one is to make a fully simulated pool experiment, set the current scientific and technological level of the Navy, and can only complete the static above the pool experiment, the effect of this experiment looks good, but this is a static experiment.

The pool experiment is very simple, get a model ship, and then according to the data can be done, but the pool such an experiment, can not simulate every environment in the sea, perhaps in later generations, with the application of the computer, there are various simulation methods of continuous progress, let the pool experiment, to achieve a certain accuracy, but in the immediate scientific and technological conditions, even, the Navy for the depth and breadth of knowledge, simply can not.

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

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

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

Card system, can copy the best of those semiconductors, as long as the direction is correct, you can constantly leap forward through the card system, there is Zhao Xin this traversal, at least in the first decade of the 21st century, or even the second part of the direction is no problem.

It sounds good, but in fact, it is not so beautiful, even the most ordinary machinery, did not figure out, there is no set of systems, and even now the power above, just into the steam engine, has not yet got the steam engine to the peak, not to mention the internal combustion engine and electricity, the computer is out of reach.

Since the computer is so out of reach, then the pool experiment is impossible, so that only the second can be used.

The second, which is what Zhao Xin once thought, is also ready to work in that direction, after all, the computer was developed during World War II, and even in the 1970s and 1980s of the 20th century, the large-scale development of things, before that, how to design the ship?

It is very simple, that is, through experience, theory, and even sea trials, gradually accumulated experience, and finally form a mature program.

This is a very common set of programs, but at the beginning, Zhao Xin would rather take shortcuts, rather than choose the root of the problem, this program, the Navy has no accumulation, if you want to follow this, you must start from scratch.

This is the most lacking in the Navy, the Navy every project, is a leapfrog development, sometimes, the new equipment, has not yet touched the more skilled premise, there has been a better equipment, which is a lot less accumulation process, this process, for simple, or better luck research projects, no problem, but for the ship, integrated a lot of science and technology projects, that is, natural problems, 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 not the development direction of the problem, this should be the problem of time, along this direction, step by step to solve the problem, through the sea test to accumulate experience, to figure out the contrast between density and sea, this need to accumulate.

Historically, Europe was able to quickly enter the era of sailing ships and iron ribs, because it was hundreds of years of navigation, accumulated things, a hundred years of navy, this can not be said, set the navy from the establishment to the present, how long,

The time of the establishment of the navy was later than the established navy, even from the original Chinese sailing ship, the Spanish galleon to the sailing ship, and the period did not last long.

It is equivalent to saying that a kind of sailing ship, without the premise of eating through, is replaced with more advanced, which is less the process of accumulation.

If it is not to explore North America, from the sea, all the way through the Pacific Ocean, with countless hard work and blood, this has accumulated some experience, even the small fire wheel, can not talk about, not to mention such a reluctant passage of the ship.

Now, reluctantly, and forced the accumulation of experience with iron ribs, then, has been along the right path development, the next, is the problem of time, how to figure out the proportion of the real sea conditions, at the same time the problem of this center of gravity, these if not accumulated, even if it can be successfully made to the appropriate ship, the future, once expanded, or other uses of the premise, is still blind.

Time can be saved, there is a futures vision, does not represent everything, unless, Zhao Xin can now computer-aided design, as well as intelligent pool to get out, otherwise, it can only accumulate.

From the beginning, it takes courage, especially the Navy, has completed a lot of preparations, even 500 tons, 1000 tons of drawings are drawn, but also need to start from scratch, this is equivalent to everything before, is wasted.

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

This is not the only problem of the ship, the ship is called systematic engineering, he is a lot of sub-projects, are combined, focus and design problems, but one of them, the power system is the most critical.

Even the fixed navy, in terms of steam power, has been in operation for many years, steam locomotives, have been popularized throughout the Navy and Northern Song, now have more than 3,000 kinds of steam locomotives, which has been very mature.

But the steam engine to push the train, and the steam engine to push the ship, this is two different things, one is the transmission shaft, push the roller, non-stop reciprocating, the other is the propeller.

The roller, as long as it is iron, just in line with the railway, on the land, forward, it is not a problem at all, but the propeller is not the same, it requires a power device, and the mission of the reciprocating operation also needs the transmission device, if the design is not right, it is prone to problems.

In addition to the power device and transmission device, the propeller is also an important problem, the future of the propeller, is not directly forged out, after processing, must be in accordance with a certain design, processing, so as to be able to reduce the water resistance to a minimum.

But now, not even a qualified machine tool, not to mention the three-axis five-axis and the like, that is almost impossible to complete the task, for the processing of the propeller, but also took out a few different forms, cutting methods, reluctantly made a few, and selected the best one.

The problem of propellers, which is the problem that is considered later, with the CNC machine tool can choose the surface processing method, or according to the study of fluid mechanics, through calculation, find out the most reasonable method, with manual methods.

Do not underestimate the manual method, in a sense, the manual is not necessarily weaker than the machine where to go, the premise is that the manual must reach a certain state, for example, the former eight-level workers.

At present, after many aspects of training and training, with eight-level workers more than 1000 people, the reason is that the Northern Song and Chinese traditions, craftsmen are passed down from generation to generation, there are some unique keys, on the other hand, some refining methods, perhaps can not let the craftsman, become Hercules or Superman, but it is stronger than the average person is sure.

Some unique exercises that increase stability, increase strength accuracy, and persistence are very important aspects for the eighth-level workers, and these are also the cornerstones of the entire fixed navy.

The leapfrog of the Navy is too strong, from handicrafts, not even basic industry, suddenly built a huge heavy industry, all aspects of the leap are many, these leaps, not without hidden dangers, but there is no such as ships such an outbreak.

Above the material, the Navy itself has a huge advantage, a strong, directly let the Navy in the material explosion table, plus Zhao Xin's guidance, a variety of graphics, design above the problem, processing above the problem is highlighted, the 1000 eight-level workers, can be said to be the Navy's treasure, responsible for processing, are some important machines, there are some grading 7-level, 6-level workers, these people, jointly build the high-end processing of the Navy.

Unfortunately, in what the powerful individual, or can not be compared to the whole, the construction of the future generations, how many machine tools, some high-precision machine tools, their processing ability, is above the workers, which can create scientific and technological innovation, but the 11th century fixed navy, is not able to achieve.

The propeller, temporarily from several designs, choose to promote the strongest force, all aspects of the standard is also the highest one, the temporary propeller and transmission system, can only be so.

As for power, this is the key to a ship, it is reasonable to say that the most high-end technology of the Navy should not have problems, but it is a problem.

The transplant on the train to the ship, itself, is a very difficult thing, the train and the ship, these are two systems, the same initially took a lot of detours, and the center of gravity and density is not the same, that is can be seen directly, if there is a problem, it can be adjusted directly, but the power above, it can not be seen.

The value of the power, the speed that can be pushed by the ship, at what speed, no one knows, Zhao Xin knows, is only the simplest kind of physical formula, similar to the ship above, and the formula between power and energy, speed, which is really beyond his understanding.

This makes the power problem, in the beginning, is ignored, until the power is a problem, at the same time, another use of auxiliary power, not all-steel ships, but iron rib ships, they are incessantly recording data, suddenly found that in the use of a smaller steam engine under the premise, ran out of higher speed.

At first, the researchers thought it was wrong, but through the comparison of the sextant, the whole data was correct, then, the impact of the wind was thrown away, and the wind was all down, the sails were all landed, there was no wind effect, and there was such a high data, which had a problem in the middle.
