After YY was completed, Wang Yan of the workshop instructed again: "Don't be blind, the speed of seven knots is indeed not good, and there is a need to climb up, but I think for the time being, with the process and design ability of Da Song, fifteen knots is a relatively optimized comprehensive node." Whether it is the design of the car body, the design and manufacture of the axle, or the design and manufacture of the transmission system, all of them are considered with the node of 15 sections, and optimized around this node. First slowly accumulate enough experience, understand the low-speed and high-load mode, and after stabilizing, then challenge other nodes. ”

The technicians couldn't help but look at each other, but Lu Huiqing was extremely embarrassed. Because in fact, Lu Huiqing felt that the speed of seven knots was too low before, saying that it was at least multiplied by five, and the speed of thirty-five knots was enough.

After Wang Yan noticed their strange expressions, he asked, "Why Mao doesn't speak anymore?" ”

It was really inconvenient for others to say, so Lu Huiqing simply turned herself in and said, "Eh...... The lower officials felt that the speed could not be improved and the efficiency was too low, so my request to them was to refer to the thirty-five sections. This is a reference to the spirit of Lord Xiao Wang, you once said that if you eat less and eat more, if you can't hold a stone, then knock it open, go faster, and carry it many times? ”

I'm @#¥

Wang Yan is the wronged person who is behind the pot, but after thinking about it, he couldn't help it, he looked around and said: "I did say these words, but the affairs are not static, don't treat me as a god, and what I said is not a holy decree." It is necessary to seek truth from facts and make conclusions with more scientific data. At present, everyone's scientific and technological foundation is still weak and they don't understand much, so it is easy to understand my words one-sidedly, and it will happen to be reversed. ”

After a pause, he continued: "Then I can answer Lu Huiqing's question now, with the same weight, without changing the current wind resistance of the car body, thirty-five knots are only more than twice as fast as fifteen knots, but I can tell you that it needs to consume about seven times more mechanical power, especially in the current axle and transmission system are immature, and the conversion efficiency is low, this is a black hole, and the development of thirty-five knots per hour train will become a technical war that you can never win, and there will be no results after exhausting all the money. And the inheritance died. ”

Everyone couldn't help but widen their eyes and looked at Wang Yan incredulously. I don't know if it's true or not, where did this arithmetic come from, and if you want to increase the gross speed by more than double, you need to pay seven times more power output?

Ye Wushuang, who was also at the scene, couldn't help but have black eyes, raised his hand to cover his face, and lost a lot, because she had already placed an order for the locomotive and transmission system of the thirty-five sections, and the deposit had already been paid, although it had not been produced yet, it was already being designed, which was a proper loss, of course it was okay to cancel the order, but Xu Langshan was difficult to speak, he would ask for compensation according to the agreement.

In other words, Ye Wushuang also felt that the reason of more than one speed and seven times the power expenditure was a bit unreasonable, but she always trusted the Great Demon King, and the Great Demon King would fool people, but he generally wouldn't talk nonsense on this kind of issue.

After looking around, Wang Yan didn't want to discourage his enthusiasm, and said with a smile: "What I said today will be taken as an administrative order for the time being, and I will go down to check and revise it." At the same time, we also have to verify my words, and according to what I say, we can think of some methods, specific tests, which is called practice, and then gain true knowledge. The basic knowledge of the school also has some foundation, and it can also cooperate with their knowledge to carry out some reference and demonstration, which is called the combination of theory and practice. Don't take my words as a myth, what I'm talking about is just a general memory, not concrete, doubling the speed, depending on the air resistance of the car, it may only need to increase the power by three times, or it may increase the power to eight times, these are variables. What I just said is just a direction, what I can be sure of is only that the increase in speed can be gained, but the power paid is multiplicative logic, the higher the speed, the less cost-effective it is, this is certain, in our machine is immature, every horsepower is extremely critical, and it is the crystallization of R&D personnel day and night. ”

"With the accumulation of experience, consistent R&D investment and design accumulation, the goal of each generation of the machine in the future is to increase the thrust-to-weight ratio by 40% and increase the train speed by one level. I believe that in 20 years, you, the first generation of people involved in industry, will have the opportunity to see a 1,200-ton train traveling day and night across the Great Song District at a speed of 25 knots. ”

Now it's all chicken blood.

Ye Wushuang's eyes lit up, and he said with some disbelief: "Is it really possible that there will be a load of 1,200 tons?" ”

"Yes, the blueprint is in my head, but don't look at me like that, even if you trade with me in peach, I can't make it now, so I can't give it to you." Wang Yan spread his hands and said.

After all, Miss Ye is a girl, and she really wants to punch him. This bad boy talks nonsense all day long, making others think that we really have something, this is to ruin my name and my name, I am not stupid to count on the good lady, I don't need to rely on marriage to survive, otherwise the cup will be gone.

The speed of 1,200 tons and 25 knots per hour is just a dream, but the reality is very poor, and everyone is currently only doing public relations for a train with a load of 10 tons.

Next, he was not busy with the steam engine test, but also communicated with the people of the Northwest Investment Bank to test the train, and also communicated with the technical workers in the transmission train workshop of the machinery factory.

Wang Yan can talk about the truth, but he is poor in details, so he can only listen to the details of their introduction with a stupid and dignified face.

Some can understand, some can't, given the limited time, Wang Yan does not plan to be a worker, so he can't ask all the detailed questions.

At this time, Lu Huiqing said a little anxiously: "Let's test the car next, today's itinerary is mainly to visit the second-generation steam engine test run." ”

"Yes."

The steam engine team, which had been gearing up for a long time, quickly assembled, and then it was turned on.

Boom Boom Boom –

When the machine is almost running, Wang Yan can clearly feel that the vibration is much smaller, which shows that the progress of the process and the improvement of design ideas have led to a more perfect fit of the components inside.

Wang Yan was surprised, they actually designed a governor on this generation of machines?

Lao Luo, the chief engineer of the steam engine, came out and said: "This is a newly designed speed regulating device, which combines the principle of rotating centrifugal force with the valve to achieve a relatively stable and gentle power output, so that it can come in handy in some fields, which is not possible for the previous generation of steam engines." ”

Wang Yan nodded stupidly, and began to be unconscious.

Technical Zhai Ye Wushuang said proudly: "This is my uncle's experience, feedback to the machinery factory for improvement." In the past, in addition to the vibration of the steam engine, the output of the terminal was not very stable, and it was impossible to control it finely, resulting in many application projects that my uncle was developing did not progress. So my uncle put forward a request for this, and only then did this generation of steam engines be perfected. ”

Wang Yan couldn't help but look at Xu Langshan.

Xu Langshan looked a little embarrassed, nodded and confirmed: "This is true." The Ye family is now our only and largest customer, ordering 600 steam engines, and the development and application of them are also the most in-depth involved, our factory must consider some of their reasonable requirements for the long-term interests, so in order to increase this device, the design cost of this generation of steam engines is higher than expected. And then...... The governor node is regarded as the technology of the Ye family, which has been authorized to be used by our factory for 75 years, and the license fee has been bought out at one time. ”

Wang Yan couldn't help but be furious, and vaguely felt that he could buy something that could be robbed, why should he buy it? Of course, objectively speaking, it is true that it is difficult to grab the Ye family's things, especially after they set this precedent, and the resistance to intellectual property legislation in the future will be dozens of times smaller.

It's just that now they have mastered some black technology, which is really unpleasant.

There was no way, Wang Yan had to nod and said: "That's good, anyway, our factory won't lose money, so be generous, and don't ask the Ye family for additional machine upgrade fees." ”

"You even want an extra upgrade fee, and you think our agreement doesn't exist? Why don't you go to heaven, or just draw a knife and rob it? Ye Wushuang's face suddenly had a black line.

"I'm just talking, not kidding? And don't change the topic, tell me, what more applications can you use this speed regulating device, and develop this technology for the Mao Ye family? Wang Yan said.

Ye Wushuang said proudly: "The other black technologies of my Ye family will never be revealed to you now, and I will be angry with you." ”

"It's more realistic, I haven't seen any black technology you think it is, tell you, I have the blueprints for the Star Destroyer, and I won't use the new technology for you in the future." Wang Yan said.

After the two gentlemen finished arguing, Xu Langshan said with a smile: "Yanei, now the vibration of the machine is smaller, and there is a speed regulating device to provide more stable output, so that some processing with higher precision requirements can be achieved, and manpower can be further saved." ”

Then Lao Xu pointed to a set of workbenches in the distance and said: "Look at the Yanei, it is our newly developed machine tool, the original shape is yours, but it has undergone a lot of modifications, and it can be matched with the steam engine." ”

Groove that is a boring machine for crossing. In the past, it was really simple and had to be operated manually, and it could not be driven by mechanical power, but now they have changed it to look like it, and they have really accumulated a lot of design experience, and they also use mechanical power to match.

Lao Luo's father came out and added: "Lord Xiao Wang doesn't know that in the defense of the city wall of Funing County at that time, the thirty-seven heavy artillery pieces that were temporarily produced were processed with the machine tool you saw. ”

Awesome.

However, it is only now that I know that they really treat me as a god and have they set me up?

should really leave, because Wang Yan is no longer needed here, Wang Yan's historical mission is basically completed, and if he is cheeky and keeps, in addition to being criticized by the imperial court, it will also block the progress of newcomers, and people seem to be getting less and less welcome.

After this YY was finished, Wang Yan asked again: "In addition to the Shenwu cannon, can it be used to process flintlock guns?" ”

Lao Luo's father was a little embarrassed, and his apprentice who was in charge of the flintlock pistol section came out and shook his head and said: "Lord Hui is not good for the time being, and he is still testing and modifying, because the fineness of the flintlock pistol is required to be an order of magnitude higher. ”

Wang Yan was slightly disappointed, so he had to nod and say, "That's good, you guys...... If you want to do it quickly, and ah, these key things must not be deceived by Ye Wushuang, and any technology that authorizes them to use the machinery factory in the future needs to be approved by me. ”

Of course, before the next full-scale war in the Great Song Dynasty, the Great Demon King will definitely see more awesome production capacity and black technology.

Everyone thought so when they sent Wang Yan out of the machinery factory......
