Reborn Xiangjiang Tycoon Growth

When Bao Zixuan returned home, he saw Li Yulin waiting for him in the living room. It seemed that his mother was still worried about him. However, when he thought that Li Yulin had just recovered from a serious illness and was still recovering from a serious illness, Bao Zixuan had not rested so late.

I can't bear it.

Bao Zixuan asked with concern: "Mommy, why haven't you rested so late?"

Li Yulin: "Didn't you say you'd come back from playing today? I've been sleeping too much lately, so I just wanted to wait for you to come back and have a chat."

Bao Zixuan: "You are worried about meeting Zheng Yutong tomorrow! Don't worry, I won't put on any airs. I will try my best to be like a junior meeting an elder."

Li Yulin: "I wanted Zheng Jiajia to be my daughter-in-law before, but now it seems that I can't force my feelings. You can handle these things in the future!"

Hearing about her mother's sudden change, Bao Zixuan was a little overwhelmed. After all, she really wanted Zheng Jiajia to become her daughter-in-law. Why did she suddenly change now? What was the reason?

Bao Zixuan: "What's wrong with you? You suddenly changed so quickly."

Li Yulin: "You are still young, so you are not in a hurry. But after these days of observation, I found that Zheng Jiajia is not the best choice. I will not participate in these things in the future. You just need to find me."

I have no objection, but I have to look for it.”

In fact, Bao Zixuan's guess was really good. Through these days of observation, Li Yulin discovered that Zheng Jiajia was not a very ideal candidate. Before, she was thinking of increasing her son's heritage through marriage, but now it seems that it is better to find someone who is relatively simple and does not give her son

It is better to have a daughter-in-law who causes trouble, so that Bao Zixuan's interests will not be damaged due to family interests. He also analyzed the matter this time and found that Zheng Jiajia used her relationship to make Bao Zixuan compromise.

This is not a daughter-in-law that he needs to be able to take care of his son and run the house, and Miss Zheng Jiajia's temperament is not good at taking care of others. He doesn't want his son to come back from work all day and not even get a greeting from anyone, and then he will not feel at ease even if he dies.

Early the next morning, Bao Zixuan came to the Heiyun Manufacturing Center to inspect the condition of the aircraft engine. Now both the theory and processing capabilities can meet the requirements. The only thing lacking is that the basic materials are not up to standard. This is a topic that cannot be avoided.

, even the basic materials of later generations of China have never been able to provide satisfactory answers.

In the future, Germany and rb will be the two countries with the best R&D and production of basic materials, but fortunately Bao Zixuan has already laid out the plan in advance. Otherwise, it will become more passive as time goes by, and people will choke it if it does not do well. Samsung in South Korea

So a great company has no raw material supply and has to put down its attitude and seek help from RB people. Bao Zixuan doesn't want such a thing to happen to him.

Now all materials related to aero-engines come from the Soviet Union, and Lao Maozi's strength in this industry is obvious to all.

Looking at the aircraft engine that the engineers built according to Bao Zixuan's drawings. Although there are still many flaws, I believe that as long as it is implemented carefully, there should be no problems. This time he wants to become an aerospace engine supplier. If it doesn't work, he will probably produce his own aircraft.

.In short, Bao Zixuan wants to plan all the weak projects in China in advance, otherwise it will be too late.

Looking at this aircraft engine, which has gathered many outstanding engineers in Heiyun, Bao Zixuan knew that history was changing little by little. This machine should not appear in Xiangjiang, because it should be in the laboratory of the British Rolls-Royce Company. But now everything

All have changed, and this can be said to be the engine that breaks the monopoly of Europe and the United States.

There are currently three major suppliers in the aviation industry, namely Pratt & Whitney of the United States, General Motors and Rolls-Royce of the United Kingdom. Even RB people are not very strong in this industry. Aviation engines have always been regarded as the pearl of the industry. Today, Black Cloud

I have mastered it. This is an extremely exciting thing, and it is also the motivation to keep moving forward.

Hartmann is a German aerospace engine engineer who is 74 years old this year. He had already reached the age of retirement, but was invited by Heiyun with a lot of money to come out. As a member of the research and development team of the world's first jet aircraft, he has been working in the automobile factory after the war.

Work. However, his love for airplanes has always been hard to give up. He only rehearses the working principle of aeroengines on his own, and his skills have never fallen behind over the years.

Bao Zixuan looked at the engine and said: "Old Hartman, how are you! Now it feels great to build this guy with your own hands!"

Hataman smiled and said: "Boss, this is simply an industrial miracle. This engine should appear in the laboratories of Rolls-Royce, Pratt & Whitney, or General Motors, or at worst, RB. I didn't expect that she would actually appear in the laboratory.

Xiangjiang, this simply subverts people’s perception.”

Bao Zixuan: "Hartman, you have to believe in yourself and Heiyun. We can always create miracles. Please introduce his performance!"

Hataman: "Compared with the dual-rotor turbofan engine used in the United States, our engine's three rotors can work at the optimal speed respectively, reducing the number of rotor stages, blades and adjustable blades. Because

With fewer rotor stages, the rotor can be shorter, which improves rotor rigidity and reduces performance degradation rate. The high-pressure turbine of a dual-rotor engine is generally 2 stages, and the 2nd stage operates at high speed.

, the rotor blades need to be cooled, while the three-rotor medium-pressure turbine operates at a lower speed and does not require cooling, which reduces cooling air requirements and ensures that the engine fuel consumption rate is reduced by 1.5%. One disadvantage of the three-rotor is the ball bearing arrangement

It is relatively complicated, but we use an arc-end tooth coupling, which makes the assembly and disassembly of the engine simpler than a dual-rotor engine that does not use this coupling.

The compressor life of the Heiyun engine is 40,000 to 70,000 hours, the medium and high pressure turbines are 25,000 to 40,000 hours, the combustion chamber can reach 40,000 hours after repair, and the disc shaft has 20,000 cycles.

It can be said that the overall performance of our Heiyun 1 engine is more than 15% more fuel-efficient than American products, and its thrust-to-weight ratio is also better than theirs. However, the only disadvantage is that the overall cost is 20% higher than theirs, mainly due to material and process requirements.

Allocating it to labor will reduce some, but not much."

As an aeroengine engineer, Bao Zixuan certainly knew the performance of this machine, but he only proposed the theory and parameters. The rest was mainly left to the German team, and these Germans did not disappoint him.

Germany is a country that is particularly developed and serious in the industrial field. They always believe that they are definitely the most powerful country in the world in the field of machinery and industry. It was only due to strategic factors that they ultimately failed. But the pride in their bones cannot be easily erased, Bao Zixuan

It is precisely by grasping this that they can regain their second spring.

Bao Zixuan said: "If there are any areas that need to be tested and continuously improved, I will give you enough time. Safety must be put first, and we must ensure that our engines can be installed on any aircraft without problems. Now

We can negotiate with some small aircraft manufacturing companies, and the price can be lowered appropriately to let people know about our engines."

"As for the other things, I'll leave them to you. I have only one request for you. Don't be afraid of spending money on a large number of tests to ensure that everything is foolproof."

Hartmann: "Don't worry, boss, I know how to do it. I will instill your requirements into every employee who produces aircraft engines. We Germans will not destroy our own brands."

This is why Bao Zixuan is relieved. However, the senior technicians and engineers in Xiangjiang Heiyun Industrial Park are all German and Japanese. This is not a long-term solution. Once the Soviet Union disintegrates, they are likely to leave, and the country may even issue administrative orders to them.

, now the fundamental solution to the problem is to build Yulin Institute of Technology as soon as possible, otherwise it will always be controlled by others.
