The Japanese mission did not stay for a long time, and went back on the same day, because if they did not leave, the sea would be frozen, and they would not be able to go back until the next year.

This short war between the two countries can be regarded as a successful conclusion, regardless of whether Japan is sincere or not, Yang Wenli only wants to keep a short peace and give the Far Eastern Kingdom time to develop.

It is really difficult and time-consuming to engage in basic science and technology, even with Yang Wenli's guidance, in a short period of time, there is no achievement at all.

Yang Wenli also knew that it was not in a hurry, but he needed a modern steam turbine powered ship very much, and he was separated from his family for a few years, he missed his relatives too much, especially his son, who had never met before, was now several years old, and he didn't know what he looked like, could he not be in a hurry?

After the departure of the Japanese mission, Yang Wenli did not want to waste a moment and plunged headlong into the industrial park.

"How? Is there any progress? ”

"Yes, Your Majesty, we have found a manganese-vanadium low alloy steel, its interatomic co-bond is very stable, preliminary test, has excellent corrosion resistance, and the yield is very high, we are doing seawater resistance test."

"Be quick, if you are sure that you have these excellent properties, you can immediately design mass production equipment, mainly plates and pipes, to a variety of thick and thin plates, and the rolling mill should be designed in an adjustable way, so that a set of production lines can produce different types of plates."

The most important thing in shipbuilding is the material, and it is necessary to resist the saline-alkali environment of special steel, which is the foundation, just like building a house without bricks, so Yang Wenli's first stop is always the material research group.

Low-alloy steel is also the main material for shipbuilding in later generations, but it is certainly not manganese-vanadium alloy steel, which is an exclusive product of Royal Industrial Science and Technology.

Yang Wenli went to the paint research team unexpectedly this time, he didn't ask about the progress, just wanted to show a few points: "The paint you want to study is used in a specific environment, first of all, it must be resistant to salt and alkali, and the second is that the adhesion should be strong, don't take off the paint in three days, at least there is a one-year service life, and this adhesion can be found through other ways, such as scraping the primer."

Also, the paint should not be brushed with a brush, but the method of electric spraying should be used to make the paint more uniform and denser.

The third is color, the warship is uniformly sprayed with low-visibility gray paint, and other colors of paint can be used on the ship's side or for other purposes.

The main body of the civil ship is white, and other colors can be used to space or embellish it for aesthetic design.

I'll talk about these points, you have to hurry up, the whole project is the lightest task of your paint team, don't fall behind others! ”

"No, Your Majesty, we are sure that we will be the first to produce results, in fact, we already have various paints, and we are doing salt and alkali resistance tests." The director of the paint team assured him confidently.

"Okay, you're doing a good job, that's it, I'm going to take a look at the other departments, goodbye!" Yang Wenli praised him with a smile, and without saying a word, he turned around and left.

At the next stop, he went to a department that he usually doesn't go to, it is the lithium battery department, there are only five researchers in the lithium battery department, of course, there can be no results, Yang Wenli also suddenly remembered some things, and specially gave them a hint.

"Lithium batteries are also called lithium iron phosphate batteries or lithium cobalt oxide batteries, of course, there are other materials, but I only remember these two, the important thing is the electrode, the positive electrode is lithium iron phosphate material, and the negative electrode is a composite material of graphite or something.

There is also the thin film material between the separators, which is very special, it can let electrons pass through, but not chemical solutions to prevent the battery from exploding, which is the main guarantee for the practical application of lithium batteries.

I don't know the details very well, it's up to you to experiment, but you should pay attention, lithium batteries are very easy to explode, you must pay attention to safety.

All right! Keep up your work! I'm gone. ”

Yang Wenli turned around and left, he came to the battery pack this time, gave them a lot of inspiration and help, it was very, very big, and gave them a clear research and development direction and several main points, and they almost took them to develop, which was a bit of an eye-catching effect on the success of the development of the battery later.

In fact, the battery also belongs to the scope of basic materials, is the new shaftless pump spray technology designed by Yang Wenli is an indispensable thing, the steam generator set, very simple, occupies less space, less pipelines, and lacks a huge volume of the main drive shaft and marine reducer, but it can send out a large amount of electricity, with ordinary lead-acid batteries can not be stored, must be high-performance lithium batteries.

In addition to materials, the most important department is the steam turbine power group, and Yang Wenli himself mainly stays in this department.

As soon as he walked into the R&D center, the director of the turbine R&D team came over and reported bad news to him: "Your Majesty, because the turbine engine is too heavy, the bearing can't bear it at all, and it will break down after a few turns." ”

"Oh! I forgot to tell you that the bearings of this kind of heavy equipment cannot use ordinary ball bearings, but membrane oil seal bearings like bushings, and its inner and outer bushings are solid, very thick, and only rely on a thin lubricating oil film between the two bushings to lubricate, which requires extremely precise technology, and I will send a personal guard to help you develop.

However, even if you develop the turbine, it does not mean that everything is fine, and you must continue to study deeply, try to reduce the weight of the turbine, and find a way to improve the material. For example, the main shaft and turbine disc can be used to use lighter titanium alloy materials. ”

"Titanium? Your Majesty, what metal is it? Wechen hadn't heard of it. ”

"Actually, the Toyowa lead-zinc mine near Sapporo is rich in titanium, which is a silvery-white metal with a very light weight and excellent heat resistance.

It is very soft in a single element, but when combined with elements such as aluminum and magnesium, it becomes an excellent alloy material with high strength and lightness. ”

"Oh...... Wechen got it. ”

"The other thing is that you have to work on increasing the speed of the turbines, and the faster you spin, the more efficient you are at generating electricity."

"Whoa! We will. ”

This is just a very ordinary conversation in daily scientific research, everyone works together every day, there is a lot less politeness, Yang Wenli raised his feet and went to the boiler development team after speaking.

In fact, the most difficult thing about the power of the whole steam turbine is the boiler, which is not an ordinary water tube boiler, but an ultra-high pressure boiler, a steam turbine is a boiler, the steam temperature before the vortex should reach or exceed more than 500 degrees, and the ordinary water temperature boiling point is only 100 degrees, which requires a huge pressure environment, so it is a thick ferroalloy.

The boiler designed by Yang Wenli looks like an engine, in fact, it is also an engine, because it not only burns steam, but also produces strong jet power, similar to a ramjet engine, the shell of the engine contains two layers of water pipes, and the outer layer of water pipe is the return water pipe of the high-pressure compressor, because the water temperature in the inner water pipe is still very high, it must be cooled again, but it cannot be cooled down too quickly, otherwise the boiler will explode, so the heating water pipe as a high-pressure turbine is simply a stroke of genius.

This combination of boiler and engine not only burns steam but also cools the engine, which can be described as killing two birds with one stone.
