Reborn in Hong Kong: The Tycoon Grows Up

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. But when I think about Li Yulin, who has just recovered from a serious illness and is still recovering from a serious illness, I really can't bear to think that she still hasn't rested so late at night.

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 slept too much recently, so I just wanted to wait for you to come back and have a chat."

Bao Zixuan: "Are you 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 had really hoped that Zheng Jiajia could become his daughter-in-law. Why has it changed all of a sudden now! What is the cause?

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

Li Yulin: "You are still young, so don't worry about this moment. But through these days of observation, I found that Zheng Jiajia is not the best choice. I will not participate in these things again 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 good. Through these days of observation, Li Yulin discovered that Zheng Jiajia was not an ideal candidate. Previously, I was thinking of increasing my son's heritage through marriage, but now it seems that it is better to find a daughter-in-law who is relatively simple and will not cause trouble for the son, so that Bao Zixuan's interests will not be damaged due to family interests. He also analyzed the matter this time and found out that Zheng Jiajia used her relationship to make Bao Zixuan compromise.

This is not a daughter-in-law who needs to be able to take care of her son and run the house, and with Miss Zheng Jiajia's temper, she doesn't know how to take care of others. He didn't want his son to come back from work all day long and not even receive a greeting from anyone, so he wouldn't feel at ease even if he died.

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 never up to par. 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 Japan will be the two countries with the best R\u0026D and production of basic materials, but fortunately Bao Zixuan has already made arrangements in advance. Otherwise, the further you go, the more passive you will become, and someone will choke you if you do anything wrong. Samsung, such a powerful company in South Korea, had no raw material supply and finally had to put down its posture and ask the Japanese for help. Bao Zixuan did not 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 country is also obvious to all.

Watching the engineers build the aircraft engine according to Bao Zixuan's drawings. Although there are still many flaws, I believe there should be no problems as long as it is implemented carefully. This time he wants to become an aero-engine supplier. If that doesn't work, he may produce his own aircraft. In short, Bao Zixuan, all the weak projects of later generations of China, want to be laid out in advance, otherwise it will be really too late.

Looking at this aircraft engine, which has many outstanding engineers in Heiyun, Bao Zixuan knew that history was changing little by little. This machine should not appear in Hong Kong. It should be in the laboratory of Rolls-Royce in the UK. But now everything has 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 \u0026 Whitney and General Motors of the United States and Rolls-Royce of the United Kingdom. Even the Japanese are not very strong in this area. Aviation engines have always been regarded as the pearl of industry, and today the black cloud has been mastered. 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. After the war, he worked in automobile factories as a member of the development team for the world's first jet aircraft. However, his love for airplanes has always been hard to give up. He only rehearses the working principle of aero-engines on his own, and his skills have never fallen behind over the years.

Bao Zixuan looked at the engine and said, "How about it, old Hartman! Now it feels great to build this guy with your own hands!"

Hataman said with a smile: "Boss, this is simply an industrial miracle. This engine should appear in the laboratories of Rolls-Royce, Pratt \u0026 Whitney, or General Motors, or at worst, Japan. I didn't expect that she would actually appear in Xiangjiang, this simply subverts people’s perceptions.”

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-stage. The second stage works at high speed and needs to cool the rotor blades, while the middle stage of the three-rotor engine The pressure turbine works 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 that the ball bearing arrangement is relatively complicated, but we use arc-end teeth The coupling makes the assembly and disassembly of the engine simpler than that of 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 a life of 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 aero-engine engineer, Bao Zixuan certainly knew the performance of this machine, but he only proposed theories and parameters. The rest was mainly left to the German team, and these Germans did not disappoint.

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. However, it was only due to strategic factors that it ultimately failed. But the pride deep in their bones cannot be easily wiped out. Bao Zixuan just grasped this point and gave them a second spring.

Bao Zixuan said: "Is there anything else that needs to be tested that needs to be continuously improved? I will give you enough time. Safety must be the first priority and we must ensure that our engines will not cause problems when installed on any aircraft. Now We can negotiate with some small aircraft manufacturing companies, and the price can be lowered appropriately, so that people can understand 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 experiments 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 smash our own signs."

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.
