Traveling through the sword to engage in military industry.

"I have some suggestions regarding your current debate," Ren Zhong said bluntly.

“For railways with a speed of less than 160 km/h, we can define 120 km/h to 160 km/h as high-speed railways, and those below that as ordinary railways.

And the railway with a speed exceeding 160 kilometers per hour can be called high-speed railway, or HSR for short. "

Ren Zhong started off by drawing a big circle for the railway at Dongda University.

"From the perspective of current technological development, 200 km/h is the upper limit for diesel locomotives, but not for all locomotives on the railway. So in the foreseeable future, we can consider increasing the upper limit of high-speed railways to 350 km/h. After all, Alstom's current technology is already very close to this speed. After readjusting and optimizing the locomotive head model, body material and track design, I believe that reaching a stable speed of 350 km/h is not a dream."

“Therefore, it is correct that electric locomotives will be the technical direction for the development of high-speed railways in the future.

But this does not mean that we will only develop one of the technologies. On the contrary, we must insist on walking on two legs and continue to develop both diesel locomotives and electric locomotives to new extremes. For diesel locomotives, we need to develop locomotives with stronger traction and higher internal combustion efficiency to continue to develop our heavy-duty railways with a capacity of more than 10,000 tons and optimize the route speed and operating efficiency of our current diesel locomotives. "

"Because diesel locomotives do not have much demand for track changes within 160 kilometers per hour, the speed increase of our current railway network is only limited to the slope and curvature of our railway line design. We can completely control it in sections to ensure the increase of the speed of the entire line.

In this regard, we need to consider the existing conditions comprehensively. This is a problem we need to study and solve now. I hope that on the main line, the straight line can be raised to 120 km/h to 160 km/h. "

"On the other hand, our future research direction of high-speed rail technology should focus on future electric locomotives. Current technology has proven the huge advantages of electric locomotives in high-speed traction. It has been proven that it is not realistic to rely on internal combustion engine technology to increase the speed of highways above 200 kilometers. Therefore, it is wise for us to abandon internal combustion engine technology in future high-speed rail."

"I hope that the advantages of electric locomotives are not limited to high-speed railways. In the future, we will also have good application opportunities in rapid railways. Although environmental protection issues have not been raised yet, when our electricity acquisition methods become more diversified in the future, high-speed trains directly driven by electricity will obviously be more environmentally friendly than diesel locomotives.

And it’s more power efficient, too.”

After Ren Zhong put forward his conclusion, Professor Zhao Xiaoming took notes and digested Ren Zhong's words.

"Dean Ren, we don't have any technical accumulation in electric locomotives, and we basically have no foundation in related key technologies. In this regard, can we choose external cooperation?" Professor Zhao Xiaoming asked after listening to Ren Zhong's words and thinking carefully for a while.

"Of course, we have never closed the door to external exchanges and cooperation. Your exchange with Alstom this time is very meaningful. You have broadened your horizons and seen the feasibility of another technical route. Although their technology may still be relatively rudimentary at present and has only experimental value but cannot be put into commercial operation, after we improve it, it is fully capable of commercialization."

"But I don't mean to limit you to this one company. Simen also has good electric locomotive technology. We can choose to cooperate with them. In terms of specific methods, no matter how we negotiate, my bottom line is that we must have complete technical data and complete intellectual property rights for the jointly developed products, and have the permission to sell them to other companies."

"This is our bottom line. Based on this bottom line, we can make some appropriate economic compensation, including the introduction of locomotives for domestic lines and the amortization of funds for joint research and development by both parties."

Ren Zhong knew that Zhao Xiaoming and his team had no experience, so he gave them direct instructions.

"We don't need to rush to reach an agreement with them. In this regard, it will be better to contact several similar companies and negotiate at the same time. We must fully display the domestic railway market. Now our railway mileage has reached 6 kilometers. We want to show them that not only is Dongda a realistic large railway market now, but with the development of the economy in the future, Dongda's 6 kilometers of railways will only be a starting point. We will continue to build new railways, from 6 kilometers to 10 kilometers, or even 20 kilometers or 30 kilometers until it becomes the world's largest single railway market. If they cooperate with us, relying on the Dongda market, they will undoubtedly become a railway equipment giant in the future." When it comes to making pie in the sky, there must be not only something visible, but also an extremely bright future.

Judging from the current conditions, the goals proposed by Ren Zhong are not completely empty dreams. The University of Tokyo in the world of "Swordsman" has a rapidly developing economy and population growth. Since the hybridization technology came out ahead of time, there is no longer much worry about food. Under the premise of promoting eugenics, the population development is generally stable, with an annual population of around 2 million. Now the population is just over 3 million. According to this trend, it may gradually grow to 1500 billion in 7 years, and then enter a period of population equilibrium. After all, the more developed the economy, the lower the desire to have children.

With such a large population and economic development, there will be a lot of population mobility between cities. Ren Zhong hates the congested road traffic in the main world, and the best way to reduce the amount of road traffic is to improve rail transportation. In this regard, the railway network in Europe is a very good reference.

The realization of intercity rail transit in economically developed areas is an essential development.

Under such conditions, the development of high-speed rail and express rail will obviously make Dongda a center of the future world.

"Dean Ren, do you mean that we can join forces with companies like Alstom to jointly build the technology system for future high-speed and express trains?" Professor Zhao Xiaoming understood what Ren Zhong meant and confirmed.

"Why not? They are ahead of us in the development of electrification. Now, except to be good students and follow up quickly, there is no other way to overtake. Learning, absorbing and then surpassing is the normal way of development of things. Of course, we have a win-win attitude. For partners, we can work together to make the pie of this future market bigger and share it. The development of the railway market is not just a market for Dongda. When the world economy develops in the future, many places will need high-speed and express railways. The overall potential market in other parts of the world will be several times that of Dongda. We have enough market space to develop." Ren Zhong said.

"But we must remember that we must master core technologies during the cooperation process. We cannot simply introduce products and be satisfied with quickly starting product production to make money. This is not the focus of our Railway Technology Research Center. In the final analysis, the core of each research center under our Liming Research Institute is to research and master core technologies in various industries, rather than focusing on immediate profits. If we do this, we are putting the cart before the horse. The focus of our work is technology research, and product research is only an extension of technology research, not a core." Ren Zhong reminded.

There are some signs now, which Ren Zhong has also discovered. Because the interests of researchers are now closely linked to product sales, some research projects have begun to pursue product realization too much, while investment in core basic technology research has decreased.

In this regard, in addition to strengthening R&D project management, giving priority to basic technology R&D, and allocating personnel and resources, Ren Zhong also began to change the rewards for basic technologies.

It is unreasonable to let those who have laid the foundation for the country's science and technology suffer losses.

The current issue with rewarding basic science and basic technology research lies in how to evaluate its potential value. Frankly speaking, it is difficult to have an institutional guarantee in this regard. Currently, it still depends on the evaluation team's assessment of scientific and technological achievements.

However, this will rely heavily on the vision of the evaluation team members and their grasp of the future direction of technological development.

Ren Zhong can refer to the technological development trends of the main world to make accurate judgments, but the evaluation team cannot.

For example, integrated circuit production technology, in the eyes of the evaluation team, is an intermediate node in the development of computers. It can be considered a major achievement, but it is not a groundbreaking thing because they did not realize the possibility that computers could be popularized to thousands of households in the future.

At that time, not many people dared to have such a dream. Only after Ren Zhong strongly recommended personal computers, and the current personal computers came out and began to sell well, did some people gradually realize the trend of computers entering homes.

But there are still not many, because on the one hand, the functions and performance of computers are still relatively weak. They may be acceptable for home office use, but they are still far from being useful for home entertainment, especially without an Internet connection. People have no idea what a computer can do.

However, Ren Zhong can still grasp these things now, so he can exert his authority in the appraisal of the results and rate each result.

For example, the integrated circuit research and implementation team won the special (highest level) scientific and technological award for this achievement.

In terms of railway technology introduction and research, Ren Zhong also hopes that everyone can pay attention to core technologies, such as advanced power semiconductor technology, large thyristors, high-power silicon carbide converters, traction transformers, traction motors, bogies, locomotive system integration, AC transmission systems, and microcomputer network control systems. Many technologies now lack basic supporting facilities, such as silicon carbide technology and microcomputer network technology. Dongda is carrying out these projects under the guidance of Ren Zhong's main world knowledge reserves.

Future high-speed railways must have such technical support to control the safe and stable operation of trains at speeds of over 200 kilometers per hour. Without a highly intelligent railway system, high-speed and safe operation is simply impossible.

Because of this, Ren Zhong did not expect to build a high-speed rail network for Dongda overnight.

Instead, take one step at a time and be down to earth.

The first step is naturally to realize 160 kilometers of quasi-high-speed railway in local sections based on mature internal combustion engines.

During this period, the Railway Technology Research Center can also gradually study and master the technology of electric locomotives, laying the foundation for the next 200-kilometer and 250-kilometer high-speed railways.

These plans often take more than five to ten years to see the final results.

It may be necessary to divide into hundreds or thousands of basic technology research teams to carry out research.

But Ren Zhong is not worried at all that these studies will go to waste.

He has a main world as a reference for the correct route of the entire high-speed rail development. Ren Zhong will definitely not invest resources in researching seemingly beautiful technical routes such as magnetic levitation.

Let’s wait until electric locomotive technology reaches its peak before we talk about the next steps.

According to Ren Zhong, the maximum speed of Fuxing can reach 420 kilometers per hour, and the continuous operating speed is maintained at 350 kilometers per hour, which is enough for people to complete the long process of speeding up from 200 kilometers per hour to 400 kilometers per hour.

As for high-speed rail with a speed of 400 kilometers per hour or more, Ren Zhong will wait for the main world to develop further for a few decades before making any decisions.

By following the development footprints of the main world, Ren Zhong will not make the mistakes of being too ambitious.

"We understand, and will continue to adhere to the research ideas advocated by President Ren to delve into core technologies." Professor Zhao Xiaoming joined the Liming Research Institute later, and he really admires Ren Zhong.

There are more and more research centers in the Liming Research Institute now, but no director of any research center dares to say that he can see the future development trends in his field more accurately than Ren Zhong.

"We will have in-depth discussions with potential partners such as Alstom on joint research on technology."

With Ren Zhong's clear guidance, Professor Zhao Xiaoming has a clear view of his key tasks.

However, after the contact, the negotiations turned out to be more difficult than Professor Zhao Xiaoming had imagined.

Alstom only wants to sell products to Dongda and doesn't want to mention the technology at all.

Alstom understands the difference between selling chickens and selling eggs.

However, in the face of Alstom's resistance, Ren Zhong listed a dense list of new high-speed rail research projects, and then Dongdatong Ximen Company also began to contact for negotiations.

Although Siemens was unwilling to accept the spread of its research on electric locomotive technology, in the face of the strong research capabilities of Southeast University, when the new electric locomotive research plan was listed, Siemens and Alstom were both silenced.

For the technological development of more than ten key subsystems of electric locomotives, Dongda has very clear development ideas and key research projects, and even lists very specific performance indicators. For these two industry experts, they can certainly tell whether this is a bluff or really feasible.

In addition, the plans for two 200 km/h high-speed railways, the Beijing-Fengtian Line and the Beijing-Shanghai Line, were put into planning and construction and were expected to start construction within 10 years. Eventually, both companies had to put their heads down and signed a technical cooperation framework agreement with Tokyo University for the three companies to jointly develop the next generation of high-speed railways.

The three parties established the Eastern Star International High-Speed ​​Rail Company to jointly develop the next generation of high-speed rail technology and production. According to the investment ratio, Dongda invested 45%, Ximen invested 30% and Al invested 25% to divide the equity.

The project goal is to achieve commercial operation of 200 km/h high-speed railway within ten years and 300 km/h high-speed railway within twenty years. As the leader, Dongda will be the first to build a commercial demonstration.

Another new field has begun a grand journey. Although Dongda will bear the greatest risk (mainly because the demonstration project construction department has no allies to amortize expenses), the heavy responsibility of knowing the future high-speed rail technology will not cause any major problems in this demonstration, so this demonstration will take the lead in eating the first crab, and the sooner it is built, the sooner it will benefit.
