Chapter 382 High Temperature Materials (First Update)
"What's wrong?" the little widow asked suspiciously with wide eyes.

Liu Hai said: "What time is it now? I also heard it from the second uncle in the afternoon. You also said it now. This is a superstitious statement. If someone with a heart hears it, will it be detrimental to the second uncle? Which family next door is thinking about you?" Not very good." Liu Hai was talking about the old man next door to the little widow.

"Ah..." The little widow didn't think so. After all, there is a saying in the countryside that everything bad has Feng Shui reasons. Some are homesteads, some are ancestral graves and so on.

"You can tell the second uncle tomorrow that you must be on guard against these things." Liu Hai warned again.

"You are so smart." The little widow nodded fiercely. After all, the second uncle is now the master and the workshop director.

"Will the workshop director be selected at the end of the year? And I heard that someone is collecting information on the current factory director..." The little widow started gossiping again.

When Liu Hai heard this, he nodded and said, "Don't tell the second uncle. Otherwise, if you say this, the second uncle will be surprised how smart you have become."

"You dead man..." When the little widow heard Liu Hai saying that she was stupid, she stretched out her hand to pinch her.

Then there is the fight between goblins. The female goblin has a round figure. After all, she is working, and there is no trace of fat on her figure. After all, life in this era is not that good no matter how good it is.

In the end, it was obvious that the goblin was no match. After a few rounds, he was just at his mercy.

When he went to work the next morning, the second uncle looked at some female apprentices who had not slept well and asked: "Didn't you sleep well?"

"I didn't sleep well last night." The little widow wanted to strangle the donkey sitting in front of her... She was a capable thief. At the same time, she was confused. The two of them seemed to be together a lot, so why didn't she get pregnant? Could it be that Erzhuzi and Xu Damao were also tricked by this donkey?

The second uncle nodded: "I'll arrange something easier for you in the factory."

The second uncle thought it was a time for women to have inconveniences, so he nodded and said, Xu Damao also got in the car at this time and glanced at the little widow.

Soon two more female workers came up and sat next to the little widow.

The vans were packed to the brim. If they were checked for overloading, no van in Kyoto could escape. As for checking for drunk driving, it is estimated that more than 90% of the drivers would have to go in.

When they arrived at the steel rolling mill, Liu Hai pulled the second uncle, waited for the others to get off, and then said: "Second uncle, be careful what you say and do these days. The wind is probably getting stronger and stronger. How did your factory director come to your factory in the first place?" , you know better than me."

"Yeah." The second uncle heard this and hummed. Liu Hai must have had his source of information for saying this. He had no idea that it came from his female apprentice.

The director of the steel rolling mill came here to pick peaches, and he even failed to fulfill his promise. There are some people who you can't do anything you want to do with him, but it's okay to try to ruin your business.

This is also the case in future generations, even if some people seem to have no rights, they are still respectful to others. For this kind of person, if you want to ask him to do something, you will definitely not be able to do it, but if you want to get things done, you have to respect him as your grandson. Otherwise you won't be able to get things done.

Liu Hai came to the maintenance department and found that Sun Aiguo was already waiting, and he felt that something might happen.

"The leader came to see me so early today. What's the matter?" Liu Hai asked while changing his work clothes.

"You have done research on materials. Your superiors have some high-temperature resistant materials. Can you think of a way?" Sun Aiguo pointed directly to the material opening on the table.

When Liu Hai heard this, he poured water for the factory director first. The boiling water in the thermos bottle had already been filled.

"I don't want to drink water anymore. You have to take a look first." Sun Aiguo refused.

Liu Hai put down the thermos bottle, then picked up the information. After one glance, he knew what this thing was for.

"This needs to be researched and studied. I can't guarantee it." When Liu Hai saw this data requirement, he knew it was a solid rocket nozzle.

The materials for liquid rocket nozzles and solid rocket nozzles are completely different.

The liquid rocket nozzle is similar to an oxygen welding cutting gun. It looks like a very high flame, but the muzzle temperature is not very high.

Moreover, the liquid rocket nozzles are double-layered. Everyone who has used a lighter knows that the lighter liquid will freeze when it is sprayed out.

There are many pipes in the middle of the double-layer nozzle of a liquid rocket. The fuel of the liquid rocket enters the combustion chamber through these pipes, which on the one hand lowers the temperature of the nozzle.

On the other hand, preheating the fuel entering the combustion chamber kills two birds with one stone.

Therefore, the high temperature resistant materials of liquid rockets generally only need 1800 degrees or even lower.

Because solid rockets use solid fuel and there is no liquid fuel to cool them when burning, the solid gunpowder also contains particles when it is sprayed, just like the sprayed sand, so the nozzle needs to be made of non-metallic materials.

Liquid rockets are generally used for working times greater than 200 seconds.

Moreover, liquid rockets have another advantage. They can adjust the thrust midway and shut down the rocket and restart it. In our history, there was a problem with the rocket launch. After the rocket was shut down, the problem was solved and then ignited again.

Solid rockets are generally used for operating times less than 200 seconds.

Solid rockets contain solid gunpowder. Once ignited, there is no way to stop it.

The nozzles of early solid rockets were still made of tungsten alloy, followed by composite materials such as graphite, boron nitride and ceramics, which were all disposable anyway.

But solid rockets react quickly, and liquid rockets must be filled with fuel before launch.

Generally speaking, road-mobile missiles, anti-ship missiles, and many air-to-air missiles use solid rockets.

Liu Hai saw that the technical requirements were obvious, and he was planning to build road-mobile missiles, because we can already manufacture air-to-air missiles for aircraft.

"Okay, you work first. It's not a formal task for you. I just want to see if you can think about it." Sun Aiguo nodded when he heard Liu Hai say this.

"Your main focus should be on the large transport aircraft." Sun Aiguo warned again.

"Is there any problem with the transport plane?" Sun Aiguo asked again with concern.

Liu Hai shook his head: "It's not a big problem, it's just more troublesome. The cargo plane is better. The design will be basically finalized after the year. But after the prototype is manufactured, problems may arise during the test flight. With luck, it will take three months." After six months, the finished product of the second prototype will meet the requirements. If there are still deficiencies, a test flight period of three to six months will be needed."

"Don't be afraid of this, just take your time." Sun Aiguo calculated, which means that the cargo aircraft model can be finalized as soon as the end of next year.

"The passenger plane is more complicated, but samples should be available half a year after the success of the cargo plane. The system integration will be simpler for the time being." Liu Hai said again.

The passenger aircraft system at this time was not as complex as that of later generations. The multi-functional media systems of later generations are not needed now.

Sun Aiguo often goes to the aircraft workshop and naturally knows that passenger aircraft require many more processes than cargo aircraft: "Take your time and don't rush. I just don't know what the Pioneer brand will be like this Christmas. If it's not ideal, I'm afraid the car production factory will The fourth phase of the project will not continue.”

"It's hard to say." Liu Hai knew that Christmas this year was the day when the Pioneer brand car would be launched. Leaders at all levels were worried. After all, they had previously signed an intention to sell 200 million cars. This is 200 million cars. There were 60 million cars in the 200s. ….

Sun Aiguo sighed: "I guess the dealers are also under a lot of pressure."

When it comes to business, it’s really hard to say sometimes. There’s a bit of mysticism involved in this thing. It doesn’t mean that your products will sell easily if they are good, and it doesn’t mean that they will sell easily if your price is low.

Sun Aiguo continued: "Our factory has been in the limelight this year, with helicopters, transport planes, and upgraded excavators."

"Xiao Liu, you deserve the most credit for your contribution." Sun Aiguo looked at Liu Hai. The leader said it well. Xiao Liu is a talent that will not be replaced by several divisions.

In just a short time, imported helicopters have been copied successfully. The leader also said that in the future, more advanced equipment will be purchased for Xiao Liu to study.

"The leader is very polite. I am a member of the factory." Liu Hai replied with a smile.

"Then you're busy. I have a lot of things to do at the end of the year." Sun Aiguo was about to leave after finishing talking about everything.

Liu Hai nodded. It seemed that the high-temperature resistant materials of the turboshaft engine had attracted the attention of the superiors, and that was why Sun Aiguo came to make a trip.

Although the nozzle of graphite material is severely oxidized, this thing is originally disposable.

Road-mobile missiles have many advantages. Just like large intercontinental missiles, they are basically liquid fuel and need to be refueled in advance.

"Should it be made of graphite material? Or of ceramic material?" Both have their own advantages. Ceramic materials are used in the belly of the American space shuttle.

When bangs pass through, ceramic materials account for a large proportion of composite materials. Ceramic materials have characteristics that other composite materials do not have.

Especially in the fields of high temperature resistance and wear resistance, it has more advantages than other composite materials.

Liu Hai put down his task first, went to the next door to feed the mice and rats, and then took notes.

Then I went to the maintenance department's workshop to see the manufacturing progress of the mixer truck, and then strolled to the two sports car workshops and handicraft workshops for a while.

Then I returned to the office and continued to work on my own large transport aircraft.

In my mind, I was thinking about whether the F4 I threw would change the cognitive gap we had when studying Master Ba.

Historically, the Eighth Master who is being studied in China is completely different from the second-generation Eighth Master who followed. To be honest, the first-generation Eighth Master was just a rocket controlled by a large person.

The first generation Ba Ye has a nose air intake. Although the nose air intake is beneficial to high altitude and high speed, there is no place to install a large radar.

If there is no place to install a good radar, what is the use of the equipped air-to-air missiles?

It is even said to be a day fighter because it is useless without radar at night.

Moreover, the early Pili-[-] missiles could not be launched towards the sun due to material problems.

The second-generation Baye absorbed the aerodynamic layout and flight layout of the F4 and MiG-23, and then changed it to air inlets on both sides, but how long ago did that take?

Moreover, the engine first turning time of the first generation Ba Ye was only 50 hours, which increased to 80 hours in the 200s.

Moreover, the production team of Yiyibaye also had to change people due to hair drying, which is why Liu Hai did not want to get involved with other teams.

And starting from 72, the relationship between Lao America and us eased until 89.

This period happens to be a time for harvesting wool, and now that the country is so rich, it is estimated that they are even more willing to spend money to buy technology.

"We are just waiting for the east wind from North America to take the lead!" Liu Hai is waiting for the east wind from the United States.

Some technologies just take this opportunity to come out. When the time comes, the North American leaders will be horrified to find that if a good thing comes out here, why does the rabbit on the opposite side follow suit?

Then, if we spread some technologies backhand, we might be able to change the situation where North America is dominated by one company.

Maybe some technologies can be taken out in advance and exchanged for some good things. For example, the failed F117 can be taken out and used to get some good things from Xiong Guo, such as White Swan and the like.

Put aside the thoughts of the future in your mind, let's take out the large transport aircraft first. Relatively speaking, this thing is the most urgently needed.In the afternoon, Liu Hai conducted material experiments, which was to make some high-temperature resistant materials.

Liu Hai decided to come up with some materials that can be applied to liquid rocket engines.

It will then depend on whether the people above can realize the advantages of the materials inside.

In fact, Liu Hai has come up with turboshaft engine material technology, which can greatly extend the life of existing aircraft engines.

Even a simple replacement of materials can extend the life of the aircraft engine. It seems that the life of the current imitation fighter engine is only 200 hours.

This brings great waste. The material technology that I have come up with can at least increase the engine life to 500 hours.

As for the F14 that will be released in the United States in two years, the engine will have a service life of 2000 hours in the early stage, and it is said that it can reach 6000 hours in the later period. In the later fifth-generation engines, the engine of the United States is 8000 hours. Xiong Guo The is close to 4000 hours.

In fact, the 2000 hours of aircraft engines are enough for ten years based on the average annual flight training of 200 hours.

This is why a customer in the Middle East originally bought a North American F14 and used it for decades because its engine life was too long, and then used its money to clear out the parts stored in North America.

Others are constantly engaged in research, and there are leaders who give instructions. They will tell you some data today and another data tomorrow.

The bangs side does not exist at all, just like herding sheep. The leaders also have a sheep-herding attitude towards bangs, because bangs' research often exceeds everyone's expectations.

The first thing Liu Hai is testing is the high temperature resistance technology of tungsten alloy and the high temperature resistance technology of non-metallic materials. Liu Hai has to wait before taking it out. After all, he has never come into contact with non-metallic high temperature materials, so he still needs some logic first.

"After the four-engine transport aircraft, I will build the old American C2 transport aircraft to lay the foundation for future carrier-based early warning aircraft. I will officially enter the turboprop engine business, and then upgrade to four engines. Then it will be almost time to buy a Black Hawk from Aramco, and then I will Then we can build helicopters and armed helicopters openly." When Liu Hai was doing experiments and recording data, he had such a plan in mind for the future.

At noon, after dinner, Li Dali told Liu Hai when he went to work: The director of the steel rolling mill was treated for something. It is said that he only came here to pick peaches, and he also arranged for workers to have relations with him.

Liu Hai shook his head when he heard this. The group of people who picked peaches in the past are probably not getting better now. This kind of people are the most hateful. They get jealous when they see others doing well. It would be okay if they take over if they have the ability, but they are blind if they don't. Check it out to see where the popularity has gone.

"Who is the new factory director?"

"I don't know." Li Dali shook his head and said.

Liu Hai wondered in his mind whether this would have any impact on the second uncle. It shouldn't be a big problem. After all, the second uncle had many disciples and grandchildren. In addition, the production task of the steel rolling mill must be the first priority.

After getting off work in the evening, Liu Hai picked up the second uncle. When he got home, the second uncle told Liu Hai that the first uncle had indeed played a role in this incident.

"Tsk tsk." The uncle has been feeling aggrieved for a long time. The new factory director was the first to surrender. The promised workshop director has never been available, and it is even more impossible now. After all, if you can hit the Fantian Seal once, won't you do it the second time? Second-rate?

When Liu Hai was chatting with the second uncle at home, somewhere in Shudu, many people jumped excitedly when they saw the new test data.

"According to the current parameters, this high-temperature resistant material is much better than what we used before. If used as a whole, the first inspection time can be increased to 100 hours, but the specific ones still need to be produced and tested after assembly." The technicians and engineers in the turbojet engine production department were excited when they looked at the new component test data.

"Hurry up and report. Who has developed such awesome material?"

"Hey, you haven't heard yet. The helicopters sold to us by Gallic Chicken were successfully copied within a year. The prototypes were released. The prototypes produced by the helicopter factory in the Northeast are all coming out."

"These people must be from the Northwest and must be kept secret."

"That's necessary. I heard that their helicopter factory is planning to upgrade it with two turboshaft engines to make a larger helicopter."

"The Northeast will build a fighter jet with one engine, and we will build two here. Then the superiors will use whichever one is more suitable."

"The design of the aircraft we picked up is indeed more advanced than the one we designed. I don't think there is any need to make major changes, so we can just make it based on the aircraft we picked up."

"It's a pity that the aircraft engine technology I picked up will take at least a few years to fully understand."

"Actually, it's very good. This is completely different from Big Brother's technical route."

"I heard that the prototype in Northeast China has already been produced. Because of the emergence of this new material, they are preparing to use new materials for production again."

"We just have too few scientific researchers."

"I can't help it. We are only a few years old. Fortunately, this generation of college students is finally graduating. I just want to give some of us some people, even if it is to help."

"Hmm, Laomei's design is indeed awesome, much better than Big Brother's."

"Don't say this nonsense..."

Here in Southwest China, we started dismantling and researching an airplane since we picked up one in 62. After studying it for several years, we were finally ready to do it.Now what the higher-ups are saying is that Northeast China will continue to develop single-engine ones, while here we will develop dual-engine ones, but the thrust is a bit insufficient. Unexpectedly, the dawn of high-temperature resistant materials has directly accelerated the development of fighter jets.

It is precisely because Liu Hai showed the research direction of high temperature resistant material data in the helicopter material test data.

Few people know about the existence of Liu Hai, and even the leaders’ internal documents do not contain any Liu Hai’s name.

Of course Liu Hai didn't know. Because he has money and the F4 fighter jets were delivered early, he now has the ability to develop two fighter jets at the same time.

After all, these past few years have been really difficult in history. There was nothing, just a bunch of loans, but now it’s better...

On Sunday, the junior sister came with her classmates. The junior wife didn't come today, so Liu Hai left the girls alone, and they just went to herd the sheep, eating snacks and doing homework in the office.

Liu Hai is still continuing to experiment with high-temperature resistant materials. The solid rocket nozzle material has been introduced earlier, but I don’t know what generation this material from the mainland has reached. Liu Hai has come up with new material technology that is comparable to that of the United States at the same time.

And in order to reflect their own research ideas, they started experiments from scratch. With this experimental data, I believe that technicians can explore and improve themselves.

Anyway, I can learn as much as I want, which is a general direction, but the specific details still need to be tested.

"Sister Ling, it's great that you have a senior brother." Zhang Xue tore off a bit of beef jerky and said enviously.

"Huh, I had a scooter when I was a kid. I was the first one in Kyoto." Xiaoling also answered vaguely while holding beef jerky in one hand and a pen while doing homework.

"Xiao Ling, your senior brother is not married yet?" Li Mei made the same move on the other side and asked.

"One of them went abroad and said that Sister Yun had gone to see a doctor for any illness." Xiaoling continued.

"This beef is not cheap. Will your senior brother be unhappy if we eat it?" Zhang Xue asked again.

"No, just eat it. These snacks will be mine sooner or later anyway."

"Oh, you put snacks at your senior brother's place when you were in school. No wonder your mother couldn't find out."

"Don't let it slip." Xiaoling said quickly.

"It smells so good. Your senior brother's cooking is also delicious."

"Ah."

The three Xiaoni were doing homework, chatting, and eating beef jerky. Liu Hai secretly shook his head, how could these girls do so many things together.

I stewed carrots, white radish and mutton by myself at noon. It was simple and convenient, and the food was very good. I stewed it in a large pot on a honeycomb briquette stove and simmered it slowly over low heat. In the end, the radish tasted better than the mutton, and the large pieces of white radish were almost stewed. Transparent.

Because of Xiaoni, there are no messy things added to the bangs, because there are some things that girls can’t eat well.

Zhu Haiyang also came at noon, and each person had a box of mutton, stewed radish and steamed buns.

In the afternoon, the three girls went to clean up the place where the mice were bred, and then Liu Hai was sent back. The factory area was too big and it was impractical to walk back.

In the afternoon, Liu Hai just returned to the entrance of the courtyard after getting off work. He saw several people coming out and watching Liu Hai drive. These people glanced at Liu Hai and heard someone saying hello to Liu Hai and called Section Chief Liu, and then they left in the car.

"Who are these people?" Liu Hai looked at the people leaving and the second uncle with some bad expressions, so he went to his home with the second uncle, and then asked.

"The factory office, talk to me and ask me to go to the factory office. The specific position has not been arranged yet." The second uncle took a deep breath and said.

When Liu Hai heard this, he asked, "Is it because, second uncle, you were promoted by someone who left?"

"I didn't say anything on the surface. I said I had a lot of credit, I worked hard in the workshop, who are the people in the factory office, and what is the background of a young man." The second uncle let out a long sigh.

When Liu Hai heard this, he asked, "Is this what Director Li means?"

"It's possible. One time I bumped into him and a woman in the factory..." the second uncle said in a low voice.

At this time, the sound of the first uncle talking to the second pillar outside came in, and the second uncle said: "It is said that the person who takes over my position as workshop director is Lao Yi."

"Second uncle, what do you mean, do you want to continue to be the workshop director or be transferred?" After hearing this, Liu Hai probably understood that this was an overt promotion and a covert resignation. Even if you go to the factory office to say it nicely, there are many cadres there. , and in the workshop, the workshop director is in charge of many older people.

The second uncle was a little surprised. Liu Hai was trying to help him, and then asked: "Who are you going to find for this?"

"Don't ask, what do you think it's worth?" Liu Hai shook his head and said, it just so happened that he had done a lot of credit, and the second uncle was also kind to him.

"Just don't move." The second uncle's expectations were a bit low. After all, Liu Hai has been the chief of the maintenance department for so many years. Although the motorcycle factory is big, it is the maintenance department after all. If it is a workshop that produces cars... that would be great.

Liu Hai nodded. On Monday morning, before the meeting, Liu Hai came to Sun Aiguo first. Sun Aiguo was making tea. When he saw Liu Hai coming, he asked, "Xiao Liu took the initiative to ask me for something?"

"Director, let me ask you something. The second uncle in our yard, Liu Haizhong, is the workshop director of the steel rolling mill opposite. The director of their factory was no longer that person a few days ago. The second uncle works hard and is the same as anyone else. , and it turned out that someone involved him." Liu Hai spoke simply and quickly.

"I understand, let me make a call first, Liu Haizhong, right?" Sun Aiguo knew that Liu Hai did not tell lies and did not ask for help easily, and Sun Aiguo valued people who worked hard.

Liu Hai nodded, and then called the leader directly. The leader was also preparing for a meeting at this time. Sun Aiguo said directly: "Boss, Comrade Liu Haizhong at the steel rolling mill, please investigate. This person is down-to-earth and willing to work."

In the eyes of the leader, Sun Aiguo was a confidant, and he replied in three words: "I understand."

"Let's go to the meeting." Sun Aiguo looked at Liu Hai and nodded.

"Hey, you go first, I won't go with you." Liu Hai smiled, and then trotted away first.

Liu Hai was sitting near the back door and didn't take the second uncle's matter to heart. A person of Sun Aiguo's level called the leader. His relationship with Sun Aiguo was similar to that of himself. They were both considerate people. Sun Aiguo also spoke very artistically. He said directly what he wanted to do, but said that if he investigated, he would know that something was definitely going to happen.

　a little.
