"That is, they can't make it?" Sun Aiguo understood the meaning of Liu Hai's words.

"I can't say that, I'm not optimistic about it anyway." Bangs replied with a smile.

Sun Aiguo also understood, shook his head and said: "When I heard the news, I felt that something was wrong, if it was really that easy, it would be impossible to say that they couldn't build a helicopter." ”

"And I think they should have learned about the engine technology first, rather than blindly launching a new aircraft first."

"Start with the power system, and then you should understand the technology of so many materials and the design of the whole machine, and then take your time."

"But now this atmosphere is like this, and there are not many leaders who can understand the truth."

Liu Hai nodded at Sun Aiguo's opinion, Sun Aiguo's factory director for so many years is not in vain, knowing that industrial products want to be upgraded, it is definitely not such a simple thing, and the things involved in it are too complicated.

Because the motorcycle factory has led the upgrading of all kinds of construction machinery, a simple excavator upgrade factory technical department of the people blind, if there are not bangs, it can't be done at all.

Not to mention the more complex helicopters, if the other factory had enough strength, it would not have produced helicopters made by motorcycle factories at all.

It is precisely because of the lack of strength that the helicopter developed by the motorcycle factory will be produced, and now I want to use the technology given by the motorcycle factory to make a new helicopter.

"In fact, it doesn't matter, failure is also experienced, and it can also make people realize the difficulty in this, otherwise other factories will think that it is so simple for us to imitate a thing." After Sun Aiguo finished speaking, he smiled again.

Liu Hai heard that there was something else in Sun Aiguo's words, and knew that Sun Aiguo actually didn't want to hand over the helicopter manufacturing project, but there must be the above statement above.

"They do theirs, and when I make this transport plane, we will develop helicopters again, and develop helicopter gunships." The old American armed helicopter has come out, and Liu Hai is also ready to start working on armed helicopters in the 70s.

"That's good, that's good!" Sun Aiguo was of course very happy when he heard this.

When Sun Aiguo walked, his steps were much brisker.

Liu Hai waited for Sun Aiguo to leave, and continued to do his own thing.

It's not that bangs don't want to get on a big turboprop plane, it's that the manufactured parts of a big plane simply can't be made.

45,000 tons of molding machines are needed, and 30,000 tons of our country have not yet succeeded, and 30,000 tons are barely able to make fighters.

What many people don't know is that the biggest pressure parts in modern Airbus aircraft are made with molded presses in Russia.

There are many parts of the plane that bear the force, and the landing gear is one of them, and then there is the wing spar, and then the part that hangs the engine.

These require a minimum of 45,000 tons of molding machines to manufacture.

When the bangs crossed, our 80,000-ton molding machine had an overall height of more than 42 meters, 27 meters above ground, 15 meters underground, and an overall weight of more than 20,000 tons.

Why is the aircraft industry in Russia more developed? It's because they're much more advanced than us in this area.

Xiong Guo had two 75,000-ton molding machines 61 years ago, and we only manufactured 80,000-ton molding machines in 2012.

At the time of the bangs, there were seven molding machines of more than 45,000 tons in the world.

Two 45,000 tons in the United States, two 75,000 tons in Russia, 65,000 tons in France, 60,000 tons in Germany (made in the United States), and 80,000 tons in ours.

Of course, it also depends on the maximum molded size of the monomer, and when the bangs are crossed, it seems that we are the largest.

This is also why the bangs have to install the engine in the middle of the wings of the aircraft, because the piston engine is also not suitable for lifting.

Even the landing gear bangs are prepared to be piled with materials, but fortunately, the speed of the piston engine is not fast, and the bearing capacity when landing is not as great as that of a jet transport aircraft.

Liu Hai also wished that he could make a large passenger plane with a turbojet engine, but there was no way, even if it was designed now, the whole sample would be full of loopholes, and flying into the sky would be a scourge.

The smell of barbecue began to fill the air again, and the Kyoto Motorcycle Factory barbecue workshop began production again.

Under the guidance of Liu Hai, the people of the maintenance department finally completed the design plan of the mixer truck and officially started manufacturing.

The first design is, of course, a 12-ton mixer truck.

Now it is unrealistic to load a 30-ton mixer truck, not only in road conditions, but also in use.

The people here in the maintenance department are also very excited, and the supporting power systems are ready-made, mainly to integrate various systems.

Liu Hai asked them to make a prototype car by themselves, and in addition, they also had to support the mixing plant and pump truck, which were to be done later.

There are also bulk cement trucks, which come step by step.

"Wait another two years for the factory director to build a 45,000-ton molding machine by himself."

"It's really not good, just a pile of materials."

"The most critical part of the molding machine is also the hydraulic system."

"And the forging of the various parts."

Liu Hai plans to let the motorcycle factory build a 45,000-ton molding machine by itself in a few years.

It seems that the 30,000-ton molding machine, we will succeed immediately, but we don't know the specific size.

The molding machine also depends on the size of the parts that can be manufactured in a single piece, just like the largest stress beam of the Airbus aircraft has to be manufactured in Russia, because their own molding machine cannot process such a large size.

However, there is no hurry for the time being, and we must wait for the time when there is a little technical strength in China, and then we will make efforts.

This large molding machine is also the best to use in the production of drones in the future.

Sun Aiguo knew that the maintenance department had started trial production of cement mixer trucks, and he also came here to see.

"The people on your side have been brought out." Looking at the busy people in the maintenance department, Sun Aiguo said with great emotion.

"Come on with it, if you fail, you will do it again, and they won't dare to do it themselves if you don't do it yourself a few times." Bangs are very open-minded, and if there is a problem with the manufacture, it will be solved.

"You have a good mentality, unlike others who just want to succeed." Sun Aiguo appreciates Liu Hai's mentality, and the people below should be regarded as accumulating experience if they fail.

Liu Hai shook his head and said: "It's normal to fail in research, but it's not normal to fail." ”

When Sun Aiguo heard this, he glanced at his bangs: "You are saying this to others, you haven't failed here?" ”

"That's because I'm relatively low-level, I know how much ability I have, and if I do something high, I will fail." Liu Hai heard Sun Aiguo's words and explained with a smile.

"In fact, sometimes it is best to be suitable, but some people can't see it clearly, so they blindly shout that today is over this, tomorrow is over that." When Sun Aiguo heard this, he thought that what Liu Hai said was reasonable, and Xiao Liu saw it very clearly, what can be done to succeed, so that he will not waste time.

"Instead of wasting a few years on setting an unrealistic goal, it is better to complete a lower goal as soon as possible, these things we make are relatively backward in the world, but they can be used." Bangs nodded, this is determined by the times, not only now, but also in later generations, bangs have heard this kind of thing.

But one thing to say, most of these people who shout slogans now don't have much oil and water, but when the bangs cross, once the slogan is successful, hehe! That's the mountains of gold and silver.

Sun Aiguo nodded, and the motorcycle factory also got up step by step.

"Don't be too anxious, you're still young, you have time to do research, don't let yourself be too tired." Sun Aiguo told Liu Hai again, for fear that if Liu Hai was tired and tired if something was wrong, it would be bad.

Then Liu Hai waved his hand, Sun Aiguo shook his head when he saw it, and then left.

Liu Hai's daily work schedule is very tight, and the maintenance department, sports car workshop, yacht workshop, and aircraft workshop are basically gone, and they are regular.

Bangs has been looking around when commuting to and from work recently, looking around to see if there are any injured cats and dogs.

The test subjects of the drug should not be too large animals, nor too fierce animals, preferably cats and dogs, and it is best to have two or three comparative experiments.

"It's really not good, only ruthless." Bangs decided to take another look, but he couldn't find the test subject, so he had to start with the guinea pig.

In terms of medicine, Liu Hai has been prepared, it is a ginseng sent by the factory director, about 25 years or so, Liu Hai also found a similar one in the space.

When the time comes, two identical ginseng will be used for a comparative test.

The courtyard has installed radiators this winter, and it will be comfortable, and it is the kind of cast iron radiator.

In winter, everyone is basically in their own houses after work, after all, it is cold, it is uncomfortable to snow heavily, and they have to clear the snow.

"The ginseng thing is still troublesome." Liu Hai read a lot of professional books on the aircraft carrier, and found that the test steps that need to be done in drug tests are very troublesome, and various comparative tests and toxicological tests must be carried out, even if the nature of the drug itself is not clarified, but the efficacy must go through a variety of tests.

Sometimes bangs really want to give up, but a little unwilling, and later it comes to ginseng If it is useful, then what about genetics?

If there is no way to inherit this effect, then the effect is not great, but it is troublesome to inherit this, and it will take at least several years from planting to harvesting ginseng.

That is, he has not been very busy recently, and Liu Hai has time to ponder these things.

Liu Hai was reading a book at home while pondering about ginseng, and the second uncle pushed the door in, and Liu Hai hurriedly beckoned: "Second uncle, sit down." ”

"You're in this house, just one person." The second uncle looked at the inside of Liu Hai's house, which was still arranged when he got married before, and this arrangement was not the best in the whole yard, but it was not the worst.

Liu Hai smiled: "Forget it, wait until the wind has passed recently, otherwise you won't be able to sleep well." ”

"This is also, Xu Damao and his family are getting a divorce." The second uncle spoke.

When Liu Hai heard this, he asked while pouring water for the second uncle, "What's the matter?" ”

After Xu Damao got married, he didn't eat with the second uncle and Liu Hai, what happened, Liu Hai didn't know, even if Xu Damao went to work and rubbed Liu Hai's car.

But the bangs don't care, there were some friends who had a good relationship in the previous life, but after getting married, the relationship gradually faded, and there were all kinds of problems.

"His family can't stand other people's words, he hasn't been married for a few years, and there has been no movement, and he doesn't spend less money on medicine and medical examinations." The second uncle shook his head and said.

The second uncle said in a low voice: "I don't know if there is a problem in our yard, Lao Yi, Xu Damao, and the second pillar ......." ”

The second uncle whispered this, in fact, he was afraid that people would hear it, after all, he didn't talk about it now.

Liu Hai shook his head when he heard this: "What do you say when you go to the hospital?" ”

"It's not good to ask directly, anyway, the two of them have never broken the medicine jar, and they can often see the medicine boiling." The second uncle shook his head and said.

Liu Hai shook his head and said, "It's the same, I can't ask anyone about this." ”

"And I'm still young, and I wasn't talked about in the first few years." Liu Hai said again, it's really hard to talk about this child, some people have been married for several years before they have children, and some have been married for more than ten years.

"Yes, but I think that Xu Damao and Erzhuzi should have something to do with being beaten, and you also knew ...... a few years ago." The second uncle said again.

Bangs nodded: "There is a possibility." ”

"By the way, last time you said that you would find injured small animals for testing, do you want me to help you find them?" The second uncle asked again.

"No, second uncle." Bangs quickly refused, you must know that animals carry germs or something, especially those who are sick, Liu Hai has decided to use rats to do a comparative test, give the rat two knives and then suture it for a comparative test.

"Come to my house for dinner in the evening." When the second uncle heard Liu Hai's refusal, he didn't ask why, and he was also rejected by Liu Hai last time.

"Uh-huh." Bangs agreed.

I had dinner at the second uncle's house in the evening, and then I went home and went to the basement, and soon the little widow next door came.

"Xu Damao is not a thing." The little woman came to Bangs and spoke.

"What?"

"Xu Damao suspects that it is not his problem to have children, but the problem of who in his family, in front of me, he is willing to take two hundred yuan to find someone to try." What the little widow said made Liu Hai speechless.

"I don't know what kind of person he Xu Damao is, when my dead ghost was still there, his eyes didn't look at me less."

"And the things like going to the countryside to show movies." The little widow said again.

When Liu Hai heard this, he said: "Stay away from him in the future, this guy has crooked thoughts, and he can't be fooled." ”

Once Xu Damao has this thought, he will definitely not let go, and he can't say what will happen in the future, and Xu Damao himself is also a little inappropriate.

"It's weird in this yard, and there are several of them."

"Don't go out and talk nonsense, when is it?" When Liu Hai heard this, he felt that something was wrong, and in the afternoon the second uncle said, and now this one also said, to know what time it is? Could it be that someone is doing something in the shadows?

The two shifts are over, and it will continue tomorrow, but recently it is really hard to sit down, and I can't stand it if I can't sit for a while, so let's talk about it slowly.

Mainly sedentary cervical spine, lumbar spine.
