Through the process of the shipyard, you can almost see the overall industrial level of Datang, after walking down in a circle, Sun Xiangfu has to sigh that once human beings begin to embark on the road of scientific development, then, progress will be everywhere.

The shipyard now wants to concoct good timber, there can be dozens of forest farms, there are professional timber workers, according to their requirements, sent in batches, the shipyard only needs to check the quality when warehousing, directly to the material workshop on the line, almost do not have to worry about the problem of insufficient consumption.

In addition, smelting, nut beating, willow ding, steel plate pouring, various processes, the person in charge, only need to take a glance, to know whether it is now their own process, and then use the fastest, most standard practice, quality and quantity to complete their own work links.

Of course, this is only the relatively simple link of mass manufacturing, after the technology is formed.

The real progress is the R&D department, almost all of them are material experts, where to use what materials, or what is better, more cost-saving, but does not affect the effect of the change, they can handle it well.

There are all calculated reference tables for hulls of various volumes, how much internal space there is, how much buoyancy these spaces will lead to the ship, how much pressure and impact can be resisted under different hull weights, different draft tonnages, and different drafts.

After all, the construction of today's ships is still relatively simple, and there are few things that need to be calculated.

Like in later generations, India's high-end electronic computing power is not bad, but when they build big ships, they often capsize.

It is precisely because once the ship is built and the decoration is complicated, it is not just a simple calculation problem, it also needs to consider the overall logical management ability and management unity.

The people who install the windows today come to install the windows, the people who install the toilets tomorrow come to install the toilets, and the day after tomorrow there are people to install the bed frames, cabinets, water supply systems, power supply systems, lamps, dining tables, etc., etc., etc., keep installing and installing, and when they get to the back, they often can't figure out the specific data.

Then, there is no unified planning for cargo space, activity space, etc., and there is no continuous repeated model test, and when you are launched, you will encounter bumps, which will naturally be prone to accidents.

Of course, this has something to do with the fact that they are poor and reluctant to spend more money on R&D and testing.

Therefore, poverty is still the original sin.

But Datang has no such scruples, they can burn money to do research and development at will, and the profits of the shipyard are enough for them to build and dismantle one ship after another, dismantle and rebuild, and even build the failed products, directly return to the furnace and burn them, and build new ships, without any distress, when there are a variety of plans proposed by researchers, they can even directly open multiple research lines and conduct research experiments at the same time, which also has the Prince, which feels very good in Sun Xiangfu's view.

In such an environmental mode, researchers only need to use their imagination, do design, and do experiments, and it is no wonder that it has made such great progress in a few years to apply the steam engine to ships.

Sun Xiangfu and his entourage soon came to the design and research team of the shipyard, and as soon as the double door was opened, Sun Xiangfu was the first to see a huge drawing on the opposite wall.

One only needs to look at the drawings to know that it is a big guy, and the whole is presented on the drawings, the blank space, the design device of the parts, and the suggestions for the materials are all marked on it, and even a lot of sticky notes are pasted.

Sun Xiangfu's group of people was not small, they were riding on the herringbone ladder, and when the people who continued to supplement this large drawing turned around, several people almost fell off the ladder, and Sun Xiangfu vaguely felt that one of them was a little familiar.

This person is Song Xiaoyu, who he recommended to Lantian Vocational and Technical College to learn cultural and physical knowledge, but now, Sun Xiangfu can't remember his name.

"Who designed this picture?" After Sun Xiangfu figured out what the situation was, Sun Xiangfu asked them with interest.

He had just seen the scale marked under the drawings, one to fifty, that is to say, this large ship with a figure of three or four meters long, after it was built, may be nearly two hundred meters long, and the width will also reach more than thirty meters.

You must know that in later generations, a 300,000-ton oil tanker will be less than 350 meters and 40 or 50 meters wide.

Sun Xiangfu wanted to know, who dared to think so much, dared to design the ship so big, is this to build a 100,000-ton ship?

"Young Master Sun, yes, I designed it."

When he saw Sun Xiangfu himself, Song Xiaoyu was inexplicably a little excited, because this person's words back then changed his fate, or more precisely, knowledge should have changed his fate.

Sun Xiangfu saw that it was this young man who looked a little familiar, so he asked, "You are very familiar, have we seen each other?" ”

Song Xiaoyu nodded and said, "My name is Song Xiaoyu, and back then, you recommended me to study at Lantian Vocational and Technical College. ”

When Sun Xiangfu heard this, he remembered some things when he was planning an overseas exploration and investment company, and this Song Xiaoyu was still the first batch of students of Lantian Vocational and Technical College, and it should have been ten years since he graduated.

The person he recommended became a talent, which is a gratifying thing, and when Sun Xiangfu looked at Song Xiaoyu again, he already had a little more smile on his face, and said, "Then why did you design such a big ship?" With the current technology, it is a bit impractical to build it! ”

In this regard, Song Xiaoyu had a different opinion, and said, "I have participated in the research and development of the entire steam engine, and the design and construction of the steam ship, and I think that the potential of this kind of ship is still very large.

Although the ship will run a little slowly, it is better to save more than 30% of the cost of manpower, fuel and various materials by transporting some goods that do not need to be kept alive than distributing its freight volume to multiple small boats. ”

If you use four groups of large steam turbines to propel such a ship, it is indeed no problem to run at sea, but there are many other issues that need to be considered, Sun Xiangfu does not know much about this aspect, nodded and said, "Your idea is very good, and there is also a market demand for the construction of such a large cargo ship, however, all the designs cannot be taken for granted with the current finished ship."

The ship is bigger, but it is not only a matter of power, the ship's board, bearing the weight of a meal, may not hurt, but ten tons, one hundred tons, a thousand tons of weight piled together, it is likely to directly crush your entire hull, not to mention, you are going to tens of thousands of tons, so ah! The problem of stress, you can't solve it. ”

Sun Xiangfu said about this problem, Song Xiaoyu had already considered it, and continued, "Yes, therefore, the whole ship I designed needs to be poured with steel, and it must be successful, otherwise, it will be difficult to dismantle ......."

Speaking of the back, Song Xiaoyu's voice became quieter and quieter, because this is the only way it can think of to solve the pressure problem, but in fact, it is not very feasible, you know, the internal structure of a ship is actually very complicated, if you want to use molten iron to directly pour molding, it is almost impossible, and after watering and molding, can it withstand pressure?

Not necessarily.

Steel, when subjected to heavy pressure, deforms and must be designed to be load-bearing internally.

Sun Xiangfu saw his embarrassed look, and said, "If you want it to be molded exactly as you want, you must improve the current hull construction mode, at least, it needs to use a more advanced connection molding method." ”

"A more advanced way of joining and molding?" Seeing that Sun Xiangfu seemed to have a solution, Song Xiaoyu's eyes suddenly flashed with a strange light, and he looked at Sun Xiangfu with anticipation.

"Now, we have electricity, in fact, we can use it to study a temperature that can melt steel, such as using some iron and toner and other things as a medium, so that the steel can be connected into a whole according to demand, and a ship as big as yours can use a concave and convex steel plate with threaded holes, after putting it on, riveting it with screws to create a stronger pure steel hull, without thinking too much about the thickness of the bottom plate like a small boat, it is just a sacrifice of a little load capacity, and the big ship needs to be stronger."

For these aspects, Sun Xiangfu is actually just a mouth cannon, after putting forward some ideas that later generations know, let the people who really study it ponder slowly, but don't look at such a small suggestion, maybe, he will soon be able to solve the actual problem.

In the middle of the eighteenth century, before carbon arc welding came out, industrial development has been limited to a certain extent, but in fact, its principle is not so difficult, the use of a single carbon electrode, in the carbon electrode and the workpiece to produce an arc, can produce a temperature of 3,500 degrees to 5,000 degrees, enough to reach the melting point of steel, and these things, Datang now have, just need to find a suitable way to release and use.

Although this kind of single-electrode carbon arc welding consumes a lot of carbon, Datang is not afraid of consumption at all, as long as it can make good things out, with single-electrode carbon arc welding, then, the day of the emergence of double-electrode carbon arc welding is not far away, then, in the future, the metal frame will appear in various forms that human beings want, and even the manufacture of steam turbines has become much simpler.

Idols are idols, they never disappoint, more than ten years ago, Sun Xiangfu actually brightened Song Xiaoyu's life, and more than ten years later, he found a new research direction again, so that he, the optoelectronics, would play a brighter light.

Therefore, Song Xiaoyu at this moment is very excited, he can't get a steam generator to the shipyard immediately, start a test of whether it can help him, and connect the steel plate and the internal steel structure of the hull in the way he wants, if this thing is successfully tested, then, not to mention shipbuilding, the entire manufacturing industry of Datang will go to a higher level.
