"What's wrong?" The little widow asked with wide eyes.

Liu Hai opened his mouth and said: "What time is it, I also heard the second uncle say it in the afternoon, and you also say it now, this is a superstitious statement, if it is heard by someone with a heart, will it be unfavorable to the second uncle, which one next door to you is not very good." "Bangs are talking about the little widow next door.

"Ah......h The little widow doesn't think it, after all, there is such a saying in the countryside, everything is not good, there are feng shui reasons, some are homesteads, some are ancestral graves or something.

"You tell the second uncle tomorrow, these things must be guarded against." Bangs said again.

"You're so smart." The little widow nodded fiercely, after all, the second master is now the master and the director of the workshop.

"Will it be the end of the year to choose the workshop director, and I heard that someone is collecting materials from the current factory director......." The little widow gossiped 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 you became smart." ”

"You dead man......." When the little widow heard bangs say she was stupid, she reached out and pinched her.

Then there is the goblin fight, the female goblin has a round body, after all, she is working, and her body does not have a trace of fat, after all, no matter how good life is in this era, it is not much better.

In the end, it is obvious that the goblin is not an opponent, and after a few rounds, it is only at the mercy of the part.

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

"I didn't sleep well last night." The little widow couldn't wait to strangle the donkey sitting in front of her, ......, tossed, the thief was capable, and at the same time wondered in her heart, the two of them seemed to be together a lot of times, why didn't she get pregnant, could it be that Erzhuzi and Xu Damao were also damaged by this donkey?

The second uncle nodded: "I will arrange easier things for you in the factory." ”

The second uncle thought that it was inconvenient for the woman's family, nodded and said, Xu Damao also got in the car at this time and glanced at the little widow.

Soon two more women workers came up and sat down beside the little widow.

The van is packed, and if you check for overloading, no van in Kyoto can escape, and as for drunk driving, it is estimated that more than 90% of drivers have to get in.

When he arrived at the rolling mill, Liu Hai pulled the second uncle, waited for the others to get out of the car, and then said: "Second uncle, be careful when you talk and do things recently, the wind above is estimated to be getting stronger and stronger, how did your factory director come to your factory in the first place, you know better than me." ”

"Hmm." When the second uncle heard this, he snorted, Liu Hai said this, there must be his source, and he didn't know that it came from his female apprentice.

The director of the rolling mill came to pick peaches, and he promised that the things of the master were not done, and some people you want to rely on him to do something, but it is still okay to think about your things.

This is also the future even if some people seem to have no rights, but others are still respectful, this is the kind of person, if you want to ask him to do something, it will definitely not work, but if you want to get things done, you have to honor him as a grandson, otherwise you can't do things.

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 me so early today, what's the matter?" Bangs asked as he changed into overalls.

"You have research on materials, and there are some high-temperature resistant materials on the upper side, can you think of a way here?" Sun Aiguo directly pointed to the materials on the table.

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

"I don't drink water anymore, you can take a look first." Sun Aiguo opened his mouth to refuse.

Bangs put down the thermos, then picked up the information, and at a glance knew what this thing was for.

"This needs to be studied and studied, I dare not guarantee it." When Liu Hai saw this data requirement, he knew that it was a solid rocket vent.

Liquid rocket nozzles are completely different from solid rocket nozzle materials.

The liquid rocket nozzle is similar to an oxygen welding cutting gun, which seems to be extremely high flame, but the muzzle temperature is not high.

Moreover, the liquid rocket nozzles are all double-layered, and everyone has used lighters and knows that when the lighter liquid is sprayed out, it will freeze.

There are many pipes in the middle of the nozzle double layer of the liquid rocket, and the fuel of the liquid rocket enters the combustion chamber through this pipeline, on the one hand, the temperature of the nozzle is reduced.

On the other hand, the fuel entering the combustion chamber is pre-heated, which plays a role of killing 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 down when burning, solid gunpowder also carries particles when it is sprayed, just like sand particles sprayed, so the nozzle needs to use non-metallic materials.

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

And liquid rockets also have an advantage, you can adjust the thrust halfway, and you can turn off and restart, we have a rocket launch problem in our history, and after the ignition is turned off, the problem is dealt with, and then ignited and launched again.

Solid rockets are generally used for a working time of less than 200 seconds.

Inside the solid rocket is solid gunpowder, and once ignited, there is no way to stop it.

The early solid rocket vents were still made of tungsten alloy, and the later composite materials such as graphite, boron nitride and ceramics were used, all of which were disposable.

However, solid rockets react quickly, and liquid rockets must be refueled before launch.

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

Liu Hai sees that this technical requirement is obvious, that is, it is to prepare to build a road-mobile missile, because we can already manufacture air-to-air missiles for aircraft.

"That's okay, you are busy first, and it is not a formal task for you, just to see if you can ponder on this." When Sun Aiguo heard Liu Hai say this, he nodded.

"You're still focusing on the big transport planes." Sun Aiguo instructed again.

"Are there any problems with the transport plane?" Sun Aiguo asked with concern.

Liu Hai shook his head: "The problem is not big, it is more troublesome, the cargo plane is better, and the design scheme can be basically determined after the year, but the prototype is manufactured, in the process of test flight, there may be problems, luckily, after three months to six months, the second prototype will meet the requirements, if there are still deficiencies, it will take three to six months of test flight period." ”

"Don't be afraid of this, just take your time." Sun Aiguo calculated, that is to say, the model of the cargo plane can be finalized at the end of next year at the earliest.

"The passenger plane is more complicated, but the cargo plane should be able to produce samples in half a year after the success of the cargo plane, and the system integration is temporarily simpler." Bangs spoke again.

At this time, the passenger aircraft system was not as complex as that of later generations, and what multifunctional media systems of later generations were not needed now.

Sun Aiguo often goes to the aircraft workshop, and naturally knows that there are a lot more passenger planes than cargo planes: "Take your time, don't worry, I just don't know what will happen to the Pioneer brand car this Christmas, if it is not ideal, I am afraid that the fourth phase of the car production plant project will not continue." ”

"It's hard to say." Liu Hai knew that this Christmas was the day when the pioneer brand car was launched, and leaders at all levels were more worried, after all, they had signed an intention of two million vehicles before, which was two million cars, and two million cars in the 60s .......

Sun Aiguo sighed: "It is estimated that the pressure on the dealer's side is also relatively large." ”

Business things, sometimes it's really hard to say, this thing is a bit metaphysical in it, it's not that your product is good to sell, it's not that your price is low and it's easy to sell.

Sun Aiguo opened his mouth and said: "This year, our factory is in the limelight, helicopters, transport planes, and upgraded excavators. ”

"Xiao Liu, your credit is great." Sun Aiguo looked at Liu Hai, and the leader said yes, Xiao Liu is a person, and he will not change talents for several divisions.

It has only been a long time since the imported helicopter was successfully copied, and the leader also said that he would buy more advanced equipment for Xiao Liu to study in the future.

"The leader is polite, I am a member of the factory." Bangs replied with a smile

"Then you're busy, and I have a lot of things to do at the end of the year." Sun Aiguo saw that after seeing the matter, he was ready to leave.

Liu Hai nodded here, it seems that the high-temperature resistant material of the turboshaft engine has attracted the attention of the above, so that Sun Aiguo will come to run.

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

Road-mobile missiles have many advantages, just like the kind of large intercontinental missiles, which are basically liquid fuel, and need to be refueled in advance.

"Is it graphite material? Or on the ceramic material? "Both have their own advantages, and the abdomen of the old American space shuttle is made of ceramic materials.

When the bangs are crossed, the ceramic material occupies a large proportion in the composite material, and the ceramic material has characteristics that other conforming materials do not have.

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

Bangs put down the task first, went to the next door to feed the mice and rats first, and then recorded it.

I came to the workshop of the maintenance department to see the manufacturing progress of the mixer truck, and then walked around the two sports car workshops and craft workshops for a while.

I went back to the office and continued to make my own big transport plane.

I thought about whether the F4 I threw out would change the cognitive difference when we studied the eighth master.

The eight masters who are being studied in China in history are completely different from the second generation of eight masters in the back, and the first generation of eight masters is honest, it is a rocket controlled by a large person.

The first generation of the eighth master is the nose air intake, although the nose air intake is conducive to high altitude and high speed, but there is no place to install too large radar.

There is no place to install a radar, so what is the use of equipped air-to-air missiles?

It is even said by others to be a daytime fighter, because it cannot be used at night without radar.

Moreover, the early Thunderbolt-2 missiles simply could not be launched at the sun because of material problems.

The second-generation eighth master absorbed the F4, as well as the aerodynamic layout and flight layout of the MiG-23, and changed to the air intakes on both sides, but how long has it been.

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

Moreover, the manufacturing team of the first generation of eight masters also changed people because of the relationship between the blowing wind, which is also the reason why Liu Hai does not want to be involved in other teams.

And since 72, the relationship between Lao Mei and us has eased until 89.

During this period, it was the time to gather wool, and now that the country is so rich, it is estimated that it is more willing to take the money out to buy technology.

"Just wait for the east wind of North America to carry the handle!" Bangs are waiting for the east wind of Lao Mei.

Some technologies just take this opportunity to come out, and when the time comes, the North American handlers will be horrified to find that there is a good thing on their side, and how can the rabbit on the opposite side follow it?

And then spread some technologies backhandedly, maybe it can change the pattern of North America's dominance.

Maybe some technologies can be taken out in advance to exchange for some good things, such as the failed product F117, which can be taken out and flickered from the hands of Xiong Guo to some good things, such as white swans and the like.

Put aside the future ideas in your head, let's take out the big transport plane first, relatively speaking, this thing is the most urgently needed.

In the afternoon, Bang Hai carried out a material test, that is, to make some high-temperature resistant materials.

Bangs decided to come up with some materials that could be applied to liquid rocket engines.

When the time comes, it will depend on the people above to recognize the advantages of the materials inside.

In fact, Bangs came up with turboshaft engine material technology, which can greatly improve the life of existing aircraft engines.

Even a simple replacement of materials can extend the life of aircraft engines, as if the life of imitation fighter engines is only 200 hours.

This brings a great waste, and the material technology that you take out can at least increase the engine life to 500 hours.

The F14 that came out in two years from the old United States has a service life of 2,000 hours in the early stage, and it is said that it can reach 6,000 hours in the later stage, and the fifth-generation engine in the back is 8,000 hours for the old United States and nearly 4,000 hours for the bear country.

In fact, 2,000 hours of aircraft engines, according to the average annual flight training of 200 hours, is enough for ten years.

This is also why a customer in the Middle East bought the F14 of the North American handle, and used it for decades, just because the life of the engine was too long, and then used the banknote capacity to empty the parts sealed in the North American handle.

Other people are engaged in research, and there are leaders who come to point fingers, saying data today, and data tomorrow.

Bangs don't exist at all, just like herding sheep, and the leaders also have a sheep-herding attitude towards bangs, because the research of bangs often surprises everyone.

Bangs here first tested tungsten alloy high-temperature technology, non-metallic materials high-temperature technology, bangs have to wait to take out, after all, has not been in contact with non-metallic high-temperature materials, or a little logic.

"After the four transport aircraft, I will be the C2 transport aircraft of the old United States, laying the foundation for the future carrier-based early warning aircraft, which can be regarded as officially entering the turboprop engine industry, and then upgraded to four engines, and then the time will be almost in Aramco to buy the Black Hawk, and then I can make helicopters and armed helicopters in the open." When Bang Hai did the test to record the data, he had such a plan in his heart for the future.

At noon, after eating, Li Dali told Liu Hai when he went to work: What happened to the director of the rolling mill, it is said that he came to pick peaches at the beginning, and he also transferred workers to do something.

Liu Hai shook his head when he heard this, which group of people who picked peaches before, it is estimated that they can't get better now, this kind of person is the most hateful, when he sees others doing a good job, his eyes are red, if he takes over the ability, it's okay, and if he doesn't have the ability, he will go to see where the prosperity is going again.

"Who is the new director?"

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

Liu Hai pondered in his heart, whether this has any impact on the second uncle, it should not be a big problem, after all, the second master has many apprentices and grandchildren, and the production task of the rolling mill must be the first.

After work in the evening, Liu Hai picked up the second uncle, and when he got home, the second uncle told Liu Hai that the first uncle did play a role in this incident.

"Tsk." How long has the uncle been aggrieved, the new factory director came to the first one, and the promised workshop director has not been, and now it is even more impossible, after all, you can make a fantianyin once, won't it be the second time?

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

"This high-temperature resistant material, according to the current parameters, is much higher than what we used before, and the first inspection time can be increased to 100 hours if it is used as a whole, but it still needs to be produced and tested after assembly." The technicians and engineers in the turbojet engine production department were thrilled to see the new component test data.

"Hurry up and report, who is this person who has researched such awesome materials?"

"Hey, haven't you heard that the helicopter sold to us by Gallic chickens has been successfully copied within a year, and the prototypes have come out, and the prototypes produced by the helicopter factory in the northeast have come out."

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

"That's a must, I heard that their helicopter factory is going to upgrade the two turboshaft engines to make a bigger helicopter."

"There is one engine fighter in the northeast, and we will build two here, and then the superiors will see who is more suitable and use whom."

"The design of the aircraft we picked up is indeed more advanced than our design, I don't think there is any need to change it, just make one according to the aircraft we picked up."

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

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

"I heard that the original prototype in the northeast has been produced, because of the emergence of this new material, so that the side is ready to re-use the new material production."

"We just have too few researchers."

"No way, we've only been for a few years, but fortunately, this generation of college students is finally going to graduate, so I can't wait to give some of us, even if it's a start."

"Mmmm, Lao Mei's design is really awesome, much stronger than Big Brother's."

"Don't talk nonsense......

The southwest side has been dismantling, researching, and studying for several years since I picked up a plane in 62, and I am finally ready to do it. Now the above means that the Northeast continues to engage in single-engine, and here it is engaged in double-engine, but the thrust is a little insufficient, but I did not expect the dawn of high-temperature resistant materials, which directly accelerated the development of fighters.

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

Very few people know about the existence of bangs, and even the internal documents of the leaders do not have any names of bangs.

Of course, Liu Hai didn't know, because he had money, and the F4 fighter was sent early, and now he has the ability to develop two fighters at the same time.

After all, it has been really difficult in the past few years in history, there is nothing, just a bunch of loans, and now it is better .......

On Sunday, the little sister came with her classmates, but the teacher didn't come today, so Liu Hai didn't care about a few Xiaoni, and a few Xiaoni herded sheep, eating snacks and doing homework while eating snacks in the office.

Liu Hai is still continuing to test high-temperature resistant materials, and the solid rocket nozzle material was taken out earlier, but I don't know what generation this material from the mainland has reached, and Liu Hai has come up with a new material technology comparable to Lao Mei in the same period.

And in order to reflect their own research ideas, do experiments from scratch, with this test data, I believe that technicians can explore and improve by themselves.

Anyway, how much you can learn is as much as you can, that is, a general direction, but the specifics still need to be experimented.

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

"Hmph, I had a scooter when I was a kid, and I was the first one in Kyoto." Xiao Ling was also holding beef jerky in one hand and writing homework with a pen on the other, and then replied vaguely.

"Xiaoling, your senior brother is not married yet?" Li Mei did the same on the other side and asked.

"There is one who went abroad and said that Sister Yun went to see a doctor for any illness." Xiao Ling continued.

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

"No, eat it, these snacks will be mine sooner or later."

"Oh, you put snacks here with your brother when you were in school, no wonder your mother can't find out."

"Don't talk about leaking your mouth." Xiao Ling hurriedly said.

"It's so fragrant, your senior brother's cooking is also delicious."

"Hmm."

The three Xiaoni chatted while doing their homework, and ate beef jerky at the same time, and their bangs also shook their heads secretly, how could this girl do so many things together.

At noon, I stewed carrots, white radish mutton, simple and convenient, and the food is also very good, directly stewed in a large pot with a honeycomb coal stove, simmered slowly over low heat, and finally came out of the radish is better than mutton, and the large white radish stewed is almost transparent.

Because of Xiaoni, the bangs didn't add messy things, because some things girls can't eat well.

At noon, Zhu Haiyang also came, one person and one lunch box of mutton stewed radish and steamed buns.

In the afternoon, Sanni went to clean up the breeding place of the mice, and then the bangs were sent back, the factory area was too big, and it was unrealistic to walk back.

In the afternoon, as soon as Liu Hai returned to the gate of the courtyard after work, he saw a few people coming out, watching Liu Hai drive, these people glanced at Liu Hai, and heard someone calling Liu Hai to call Liu Section Chief, and a few people took the car and left.

"Who are these people?" Liu Hai looked at the few people who left, and the second uncle had some bad faces, so he went to his house with the second uncle, and then asked.

"The factory, talk to me and let me go to the factory, and the specific position has not been arranged for the time being." The second uncle took a deep breath and said.

As soon as Liu Hai heard this, he asked, "Is it because of you, second uncle, who were you promoted by?" ”

"I didn't say it on the surface, I said that I have high credit, I have worked hard in the workshop, who are the people in the factory office, and maybe the background of a young man is." The second uncle let out a long breath.

When Liu Hai heard this, he asked, "Is that what Director Li meant?" ”

"Possibly, once I bumped into him and a woman in the factory ......." The second uncle said in a low voice.

At this time, the voice of the first uncle and the second pillar talking came in, and the second uncle said: "It is said that it is Lao Yi who takes over the position of the director of my workshop." ”

"What do you mean, second uncle, do you want to continue to be the workshop director or transfer away?" When Liu Hai heard this, he probably knew that this was a bright rise and a dark fall, don't look at what the factory office said, but there are many cadres over there, and in the workshop, the workshop director is much older.

The second uncle was a little surprised, Liu Hai wanted to help himself, and then asked, "Who are you going to look for this?" ”

"You old man asked, what did you say you were doing?" Liu Hai shook his head and said, it just so happens that he has a lot of credit, and the second uncle is not bad to himself.

"Just don't move." The second uncle's expectations are a bit low, after all, Liu Hai has been a maintenance section chief for so many years, although the motorcycle factory is large, but after all, it is a maintenance department, if it is a workshop for the production of cars...... That's good.

Liu Hai nodded, on Monday morning, before the meeting, Liu Hai first came to Sun Aiguo's side, Sun Aiguo was making tea, and when he saw Liu Hai coming, he asked, "Xiao Liu took the initiative to find me something?" ”

"Factory director, I beg you something here, the second uncle in our yard is the workshop director of the rolling mill opposite, the director of their factory a few days ago is not that, the second uncle works hard, whoever goes up is the same, and someone is involved in him." Bangs spoke simply and quickly.

"I see, I'll make a call first, bangs, right?" Sun Aiguo knows that Liu Hai does not talk nonsense, nor does he ask for help easily, and Sun Aiguo values people who work 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: "Leader, Comrade Liu Haizhong over there in the rolling mill, please investigate, this person is down-to-earth and willing to work." ”

Sun Aiguo was a confidant in the eyes of the leader, and replied with three words: "I know." ”

"Let's go, let's have a meeting." Sun Aiguo looked at the bangs and nodded and said.

"Hehe, you always go first, I'm not with you." Bangs smiled, then trotted away first.

Liu Hai sat near the back door, didn't take the matter of the second uncle to heart, people at Sun Aiguo's level called the leader, and the relationship between himself and Sun Aiguo was almost the same, they were all intimate people, Sun Aiguo was also very artistic in speaking, he didn't directly say what he was going to do, but said to investigate, and he knew that something was going to happen.

A little.
