The trainset is also called the trainset, which may be a little inappropriate.

Even after seeing the situation here, Li Yuanji was a little unsure of what to call this place.

The study of trains is still their focus, after all, this is the old business that started out, and in terms of professionalism, they have a thorough understanding.

Compared with the previous trainset, the current trainset has made a more delicate distinction in the study of trains.

They divided the whole work into several departments, each of which was responsible for only one of them, and the most important department, mainly for the boiler, was the design of these two departments.

As the name suggests, the quality of a boiler is reflected in the power of the train, the core of the steam engine, in fact, is the boiler, without the boiler, all the equipment can not operate.

Therefore, the task of this department is to continue to study and find ways to make a boiler that can withstand more pressure and release more steam instantaneously.

The design department is more complex, and it is divided into several different departments, one is the overall design, and the other is the piping design.

The length of the pipe will affect the heat loss caused by the steam in the flow process, which is an unavoidable problem.

In other words, the longer the distance and the more detours there are, the more power is lost along the way.

Therefore, one is responsible for the overall design, that is, from the exterior to the interior of the boiler and all design projects except the pipes, and the other is responsible for the design of the connection pipes between the boiler and the power system to avoid heat loss as much as possible.

But this requires money, a lot of money, and it is completely impossible to rely on the funding of the Academy of Sciences alone.

Because the Academy of Sciences has more than one trainset, it is impossible to put a large amount of money in one place, which is unrealistic.

But in addition to trainsets, the Railway Administration also hopes to develop more advanced and powerful trains.

Needless to say, in the same case, the power is stronger, you can run faster, even if the speed factor is removed, at the same speed, the power is stronger, you can also hang a few more carriages, and the conclusion is that once the new generation of trains is successfully developed, it means that the overall improvement of railway capacity.

Although the carrying capacity of the railway is relatively terrifying, there is still a lot of pressure on the railway administration.

Although they have repeatedly shortened the safe time of departure, and added a lot of safety personnel to warn them on the way to ensure the safe operation of the railway, the carrying capacity of the individual is there.

And with the full opening of the Luozhou-Haizhou railway in a year's time, the pressure will be even greater.

Therefore, the railway administration also withstood the pressure from all parties and took out 10% of the net income each month as the research fund of the trainset.

Li Yuanji knew about this and did not stop it, but there is still a set of proper supervision procedures.

Therefore, most of the current train set funding comes from the direct sponsorship of the Railway Transport Administration.

Li Yuanji is not familiar with professional things, but looking at the busy scientific researchers, the thick accumulation of various drawings, and the apprentices who are making parts by themselves, Li Yuanji is still very pleased in his heart.

In addition to the old trains, the company was also responsible for the study of the marine steam system, but the project was more complicated and was still stuck with how to prevent water from entering from the outside.

Li Yuanji just knew that the method used in later generations was to inject a kind of oil into the bottom, and then through a reasonable layout, this oil was always close to the inner wall, and after the seawater seeped into the outer wall, it could not penetrate the protection of this layer of oil.

There is also a method of pressure control, but those things are too high-tech, and Li Yuanji has not even figured it out himself, let alone commanding others.

After taking a look, Li Yuanji went straight to the destination of this trip, the truck research group.

Trucks, what is a truck? It is to let the locomotive run freely on land, and there are many things that need to be improved, but there are not many principles that need to be improved.

Without an internal combustion engine, today's trucks would only use a steam engine to produce power.

And this created another problem, which was bulky and inconvenient to operate.

From the outside, it's no different from a locomotive, maybe a little smaller, but that's all.

Even, his wheels are the same as the wheels of a train, seeing this, Li Yuanji couldn't help laughing.

Jiang Tian has now completed his studies, and with his excellent performance in the research of trains, he has been entrusted with the important task of directly assuming the project director of truck research.

It's just that there aren't many people under him, and the only real researcher is him, a bare-rod commander, and there are seven or eight apprentices under him to do chores.

If you encounter a problem, you can also go back to the train crew to ask for help, after all, at this time, there is a shortage of talents in all aspects, and it is enough to give people a headache to get a marine steam engine, and no one wants to divide another one.

"That's what you're designing?" Looking at the train in front of him, Li Yuanji felt a little disappointed, a large amount of money was thrown in, and this thing came out? Or did he build a train?

Jiang Tian was stunned for a moment, and looked at the train not far away, where several apprentices under his command were still lying on it and studying.

"Your Majesty, that train was researched by the previous trainset, and it is also used for study and research in the entire trainset, and the minister's task is also to make corresponding adjustments and improvements according to this train. However, there is limited space here, so our project is actually a proving ground outside the city. Jiang Tian told the truth.

The Academy of Sciences had not only old scholars, but also new apprentices, and it was impossible to expect the new ones to have the level of the old scholars, so the train was still used there for research and study.

Of course, they couldn't find anything more suitable for it than that.

Moreover, the Academy of Sciences is located in Chang'an City, and the railway is not here, that is to say, this locomotive that was made in research cannot be separated from here at all, unless a railway is built, and then the Academy of Sciences is smashed open and the city wall is opened.

"Let's go to the proving ground!" Li Yuanji didn't have an opinion on the train, but the car was still fine.

Even if you are not a major in automobile manufacturing, it is not uncommon to see cars in later generations.

At this time, what is needed is not how professional you are, but to put forward a directional construction significance, pointing out a direction, for a scientific researcher, it is far more meaningful than telling him what to do in a certain place.

"Isn't there a train at the proving ground? Why do you want to come back to research? On the way, Cheng Zhijie raised questions, in his opinion, this is clearly a waste of time.

"There are more experts and more people here, and if you study here, you can exchange opinions with other researchers. In fact, many times the inspiration comes from accidents, and if you concentrate on it, you may not get satisfactory results. Jiang Tian once again explained seriously, not only for Cheng Zhijie, but also for Li Yuanji.

At the same time, it also shows his nerdy character, if he is a normal official, he will never reply in this tone at this time.

You must know that one of the people around him is the emperor, the other is the secretary of the military department, and the cabinet members, if the Confucian gang sees it, they will definitely scold Jiang Tian for having no rules.

But as a researcher, they focus more on the project and rarely delve into the interpersonal aspects of the project.

Even in later generations, there are many such people.

But their endings are often more tragic, and it is even impossible to go to a high position in a lifetime because of the character.

"And when will you be able to build this truck?" Cheng Zhijie lazily responded to these professional things, he paid more attention to the results, and his identity also made him pay more attention to the results, rather than interfering with them.

"It's hard to say for the time being, we have encountered two relatively large bottlenecks, and the other is that the overall details need to be further improved, if these two bottlenecks can be solved, half a year if it is fast, and a year if it is slow." Jiang Tian continued.

Regarding what the bottleneck was, Cheng Zhijie didn't ask, and if he asked, it was in vain, he didn't understand it, and he couldn't solve it.

Li Yuanji didn't want to ask, what bottleneck can be seen there, whether it can be solved is not certain, what if the game is too big now, what if you can't hold it back?

So along the way, Li Yuanji rarely spoke, just listening to the two of them talking, and at the same time secretly fantasizing in his heart.

In fact, the requirements for trucks are not high now, first of all, the price, which will definitely not be low, which also limits his commercial use, and the other is the output, which will definitely be given priority to the army after it is manufactured.

And once there are trucks, the army can completely break away from the traditional way of warfare of war horses.

What is saved is not only the war horse, but also the materials needed by the war horse.

In ordinary warfare, a cavalry unit of equal numbers prepared far more supplies for war horses than for people, for the simple reason that horses eat more than people.

Most of the current Tang Army has canceled the cavalry system, but the war horses have not withdrawn from the army sequence, and they are more used for the mobility of troops than for combat.

War horses have completely metamorphosed into a means of transportation, and if trucks appear, they can completely replace war horses, and it will also reduce a lot of pressure on the logistics of the troops.

And steam has the benefits of steam, even if the coal can't keep up, you can use it alive by chopping some firewood, but the power is not so strong, but at a critical moment, it doesn't matter.

Secondly, after the ownership of trucks, the mode of combat can also continue to change, and at critical moments, trucks can even be converted into armored vehicles.

What high requirements, what high standards, in the face of the era of cold weapons, can turn trucks into armored vehicles, and drive on the battlefield can completely crush the enemy.

Thinking of this, Li Yuanji had to sigh, technology is really a good thing.
