Chapter 619 It is not easy to go from steam engine to train
In the first month of the first month, in addition to the clear situation in northern Shaanxi, Beijing also received good news. In Fujian, with the help of Wang Er and his commando team, they finally repelled the Xiying led by Sun Kewang and successfully forced it out of Fujian.
.
Next, Fang Ruocheng and the others planned to reach Guangzhou City by sea and dig out the back roads of Xiying.
If the battle of Guangzhou City is successful, Xiying's situation will become passive! At least they will not be able to advance northward as calmly as now.
If the Battle of Guanzhong and the Battle of Guangzhou go smoothly, the two strongest combat forces hindering the unification of the country will no longer be a big problem. Therefore, Zhu Youjian's attention to the war dropped and he began to
Be concerned about things he thinks are more important for the future.
What is more important to the future? Of course it is the steam engine, no, to be precise, the train. There are so many stalls across the country. If there is no train, Zhu Youjian really can't bear it.
Taking people to the train research and development site of Tiangong Bureau, Zhu Youjian met Song Yingxing, who was leading people to do technical public relations. Trains are really important. In order to speed up the progress, Zhu Youjian transferred Song Yingxing to the project department last year.
Ask him to put aside other tasks and focus on this top priority.
"Sir, how is the progress on the train? Can we make a usable vehicle this year?" After the meeting, Zhu Youjian asked straight to the point about the progress.
songs
It’s unusable.”
"Let's take a look at the finished car first!" Zhu Youjian was full of doubts about Song Yingxing's judgment.
It makes no sense! Nowadays, steam engines are considered a useful thing, and more than a thousand of them can be built every year. In addition to being used as water pumping power at first, some industrial and mining companies are now also purchasing them as power equipment. Tinggong
The response of the production system is very good. The steam engine can be used and can be installed on the train. Are there any technical barriers that need to be broken through? It is not that we want to build a fully mature steam train. At this stage, Zhu Youjian
The only requirement is to run it, and the rest can be improved and perfected slowly.
After arriving at the test site and seeing the test run of the train made by the Tiangong Bureau craftsmen, Zhu Youjian understood why Song Yingxing said that the current one was not suitable for use.
First of all, the power separation system has not been fully developed. Once the train starts running, it is difficult to brake! Although according to Zhu Youjian's instructions, there is a disc brake system installed on the wheels. But without separating the power,
Parking can only be done by turning off the engine and manually moving the brake lever. Parking requires the cooperation of several people, and the distance is very long. This is just one car. If it has a carriage, it will probably take several miles.
to stop the car.
The parking problem cannot be solved. Trains on the road are railway killers. Not only are there safety risks for people along the way, but the people operating the parking are also in danger. At the same time, the current parking method also causes considerable damage to the machinery. Stop.
After two or three trips, the steam engine broke down here or there and could no longer be used.
In addition to this big problem, power is also a problem. The prototype car that was built cannot run on the current common carriage track. If you want to run on the common carriage track, you have to reduce the fuselage. Reducing the fuselage is not
Just switch to a small steam engine and that's it. The first thing to consider is the power problem. The small steam engine has a limited load capacity. Song Yingxing and the others have tested it. Not to mention carrying several carriages, even running with just one locomotive is difficult. To put it bluntly, it is
Existing steam engines face a core indicator that will only be used by later generations of aircraft engines: the thrust-to-weight ratio is insufficient.
The efficiency is too low and the thrust-to-weight ratio is not enough. The smaller the steam engine, the greater the problem. If it is small enough to a certain extent, it cannot even carry the coal and water used to supply itself, so how can it be used?
If the steam engine needs to be shrunk, other supporting systems must also be shrunk accordingly. With the existing technology, it is very difficult to shrink some supporting systems!
The technology is still immature. The main systems such as clutch, transmission, and power, as well as the sophistication of the manufacturing process, are still far from being able to create a mature system that drives trains to run normally. Naturally, it is still far from being able to create a suitable train.
How far.
Only today did Zhu Youjian understand why the entire industrial era was divided into generations in later history books. On the surface, the three industrial revolutions seemed to be just different in their representative machinery. However, in fact, the biggest differences among these three eras were
The difference is the gap in the overall industrial level. With the industrial capabilities of the early steam engine era, even if one knows the principles of electric motors and internal combustion engines, it is impossible to skip the steam era and directly enter the next era.
In the age of the steam engine, the resolution of general machinery was only on the order of millimeters. In the age of internal combustion engines and electricity, the resolution reached the level of wires. As for the computer age, the accuracy measurement standard for that thing is nanometers! Steam engines and trains look big, but in fact
It uses at least ten times less systems than internal combustion engines and electric power systems!
Talking about the difficulties we are facing now, we have only solved the problem of the steam engine from scratch. Everything will mature if it is not already there. There is still a long way in between. The successful use of trains is the maturity of the steam engine.
sign, and this process requires a large amount of technological accumulation. When the accumulation of various technologies reaches a critical point, the next technological revolution can break out.
"As Mr. Wang said, we are still far away from making a truly practical train. It is unrealistic to make a practical train this year. However, we are heading in the right direction. If we can't do it in one year, we will take two years."
"Two years will not make three years. In my opinion, it is possible to put shared trains on the road within five years and replace horse-drawn carriages on the railways in large numbers." After understanding the current situation, Zhu Youjian accepted the reality and put it into practice.
The expected time was put into a width of five years.
It should be possible to put the train on the road within five years! At least now we have entered the steam age, and the technical path to the ultimate form of the product is also clear. It can be successfully grinded with water and kung fu in five years.
Steam engines already have application scenarios, and now the production scale has increased. The process of maturing will definitely not be too long. Zhu Youjian is still confident about this.
"Your Majesty, please don't worry too much. From what I see, it is not a big problem to build a usable train car within three years. As long as this kind of train is built, it will be a weapon to protect our Ming Dynasty forever." Regarding the function of trains and the emperor
Song Yingxing saw clearly why he was particularly concerned about the progress of this thing. With railways and trains, the Ming Dynasty could be connected into a highly efficient network. The court's control of local areas was completely different from the previous generals. With horses,
The rail lines have changed in Ming Dynasty, let alone the arrival of trains.
"Sir, don't be too impatient. No matter how important the development of trains is, your body is not as important to the Ming Dynasty. You understand this clearly. Great talents like you are the real treasures of the Ming Dynasty. You must not make any mistakes that will cause me pain."
An important weapon that has lost the country." Song Yingxing is so old, Zhu Youjian is really worried that his body will be exhausted from working day and night.
