In the excavator production workshop, Liu Hai came here to upgrade the excavator, mainly to see the technical level of the people here.

In fact, the excavator itself is not complicated, especially in the case of motorcycle factory, existing power technology and hydraulic technology, what is needed is how to integrate resources.

"Upgrading an excavator is actually very simple, it is to calculate!" In the technical department of the excavator workshop, Liu Hai said while discussing with a group of people.

"Section Chief Liu, the calculations involved are too complicated, and the forces of each structure change." The head of the technical section spoke.

Liu Hai nodded, mainly because the knowledge of these technicians is too poor, even if they are now college graduates, it is impossible to design an excavator alone.

Don't talk about the current college students, even the college students in 2020, it is very difficult for you to ask him to design an excavator.

The systems of large machines require constant calculations, constant optimization, design changes, and constant experimentation.

"I know it's more difficult, but everything is done, this time I will lead you to upgrade, our excavator, is to let everyone learn in this upgrade." Bangs happened to be a gap in the past few days, so he came to guide the technical department here to upgrade the excavator.

The yacht thrusters are finished, the rest are not yet in place, and the molds in the carpentry shop are barely finished.

The transport plane Liu Hai is ready to copy the C46, which is also the main force of the Hump route, which can easily land on the plateau.

So there is no need to worry at all, but the demand for excavators can be upgraded to large excavators.

Liu Hai led the people of the excavator technology department to first determine the parameters of the new machine.

Then through this parameter to design, hydraulic motors, engines, these can be used off-the-shelf.

All that remains is the chassis, the hydraulic control system, the large and small arms of the excavator.

Liu Hai first led everyone to set the parameters of the whole machine, then applied the existing diesel engine, and finally divided the whole system into several groups and assigned tasks to several groups.

These people with real technical departments designed new excavators, and Liu Hai knew how bad the current technical talents were.

These technical people can be said to have a high level of education in the factory, but when doing some calculations, they still make bangs feel big.

This is the reason for the low overall level, of course, even in modern times to be able to independently design excavators, it is also a talent among talents.

The bangs mainly play a guiding role, so that these technical people know what steps need to be taken to redesign an excavator.

After this experience, the back will be much better, but the excavator behind involves the problem of computer control, which is a big technological and qualitative leap.

Before the bangs crossed, the excavator intelligence system was already very high, and there was no such complex operating lever as it is now.

In his spare time, Liu Hai flipped through the turboshaft engine information given by his superiors, on the one hand, he accurately understood the manufacturing technology of the current era, and on the other hand, he also showed it to others.

The core of turboshaft engines, turbo pulp, turbofans, and turbojet engines is material technology and design.

Material technology is mainly about material crystallization, and it goes without saying that design is this.

In fact, by 2020, our turbofan 15 engine is already a first-class engine.

Of course, the main reason is that the North American outbreaks have been eating their old books for so many years, and the F119 engines of the North American upstarts have been equipped for many years, and the new model has not come out.

Their military-industrial complex is responsible for drawing cakes when they have time, and we are responsible for realizing it.

The main thing is their military-industrial complex, which found that the world pattern is already like that, and it is basically impossible for several superpowers to want to fight, after all, everyone has mushroom bombs in their hands.

As for fighting other countries, there is no need for something too advanced at all, what is in hand is enough.

This leads to the fact that the military-industrial complex does not invest much in the development of new products, and most of the money basically goes into everyone's pockets.

An F35, how many countries have been fooled, at the beginning it was said that it was very awesome, but after it came out, there were too many problems exposed, so that it was grounded for half a year.

In fact, the F35 was a fatal flaw from the beginning, that is, it inherited the small short legs of the F22.

This is also a consequence of the dominance of the American arms dealers, who get the money, most of them return, and the remaining small part of the money tinkers, draw a big pie, and then say that they have failed.

And look at how many models F18 and F15 have improved, F18 and even the final purchase price, the unit price has reached more than 90 million US dollars, almost hundreds of millions, and the flight cost per hour is more than 30,000 US dollars.

There is also the constantly improving F15, the military purchase price of an aircraft is 170 million US dollars, while the export sales reach 400 million US dollars, and the flight cost is 42,000 US dollars per hour.

So where has the military spending gone, you can see at a glance, where there is more military spending to upgrade equipment, all tinkering on the basis of the original, I feel that this model is not going to make money, immediately upgrade a new model, research and development costs are a lot of money, and then the flight cost of the new fighter will definitely increase, and it is not surprising that there will be a strongest F15 in the universe in the future, and the flight cost of 100,000 US dollars per hour is not unexpected.

What exactly do these upgrades do? It's not that others have the final say, anyway, no equal opponent has ever fought, bullying those small countries, and you can't see the level at all.

There is no shortage of material technology bangs, and Liu Hai has been engaged in this all his life, but the bangs are still a little deficient in design, so Liu Hai must first think about the helicopter engine on the aircraft carrier.

Strive to make a general-purpose helicopter for the mainland.

"The North American outbreak is estimated to be confused at that time, and they will come up with a new fighter jet, and the other party will immediately come up with a similar one, or even more advanced than themselves." Liu Hai is very much looking forward to the honeymoon period, the North American nouveau riche will turn their faces with us, just like the big brother in the north now, obviously removed the experts, but others have developed better, what kind of bull and horse logic is this?

Shouldn't I remove the experts, and then they are finished industrialized, and they want to kneel on the ground and call our father, begging us to go to their house and garrison or something?

Big Brother in the North is a bit of a tiger ride right now.

How refreshing it was when I turned my face at first, but now I feel like I'm constipated.

And the big brother in the north also dug a pit for the little brother next door, at first it was to instigate a certain country in the South Asian subcontinent, after a rainbow flicker, the country could not find the north, and then it was almost fought by the neighbor next door to defend the capital, and anyone with a discerning eye can see that this country in the South Asian subcontinent is finished.

Of course, the industrialization of the countries of the South Asian subcontinent is also something that the other two superpowers do not want to see, although they say that they give loans to industrial equipment, but they do not want you to develop.

The current situation of the countries in the South Asian subcontinent is more in line with the expectations of the two big brothers, that is, they have no confidence to surpass the two countries.

To be honest, the countries of the South Asian subcontinent, with enough population and enough industry, are also a potential threat to the two big brothers, and now they are half-dead in the best state.

It's just that the combat effectiveness of the neighbor next door is a bit perverted, the last time 17 halls were beaten, this time 17 halls didn't dare to get down, only dared to instigate some second goods, and as a result, this second goods almost lost the capital.

This big brother supports the little brother in Southeast Asia to form the East Asian Alliance as the leader of the alliance, but I didn't expect that this time the little brother next door was not in a hurry, and the guy in North America jumped out first.

Originally, the big brother in the north wanted to pull the little brother next door into the war, as long as the little brother next door entered the field, he would stop it, but he didn't expect the little brother next door to not enter the field, what about the courage of you to hit 17 back then, do it again?

The little brother next door has the super mushroom eggs, and the flying big bricks are also there, the key is that the other party's industrialization strength is not weak, and the big brother in the north is now in a state of mind, so he has to instigate the new overlord in Southeast Asia to blame the little brother, but unfortunately the little brother lost it to some of the rags that he used to sell him.

Bangs in Kyoto, through the radio and newspapers, I know that Big Brother is a bit unauthentic.

Liu Hai thinks more about the international situation, as well as the overall industrial strength of the country.

I won't come up with too advanced helicopters now, at least I'll have to wait for Big Brother North America to go to Big Brother North America for a wave during his honeymoon period.

Because there are too many technologies involved in the aircraft industry, even if Liu Hai keeps taking technology out, don't want to come up with an overall technology for more than ten years.

Then you have to find a way to take advantage of the honeymoon period, and when the time comes, you can learn as much as you can, and you won't lose anything you can buy with money.

"The overall strength of the country is still on the propeller plane first."

"It's cheap and easy to use." Liu Hai saw it very clearly, he wouldn't engage in those tall things, tall things, and the final result was that it took more than ten years to succeed.

The main reason is that many leaders in the mainland do not understand the Tao, and they open their mouths to see how much speed and how much height, and it is easy to talk about things, but things are difficult to do.

Liu Hai now has one more workshop every day, that is, the excavator workshop, and spends two hours a day in the excavator workshop technology department.

Then there are a couple of sports car workshops and occasionally a shield machine production workshop.

"Big brother in North America, give me some strength, get the chip out early." Liu Hai looked at the industrial machine in the factory, looking forward to the stars and the moon, waiting for the chip of the big brother in North America.

It's not that Bangs doesn't want to engage in chips, but they don't have the opportunity to meddle and don't understand, Bangs really don't understand this thing, and Bangs understands the application of chips.

Of course, the general direction of the development is also understood, which is terrible, as long as you don't go the wrong way in the general direction, then it is very easy to overtake in the corner.

The C46 transport aircraft, which can be said to be a classic of World War II, has a maximum flight altitude of more than 8,100 meters, a range of 1,900 kilometers, and a load of 4.5 tons or 28 people.

This is in 1940 when the United States researched, of course, there are improved models in the follow-up, a full 26 years from now, but there is still a lot of use in China.

What the bangs have to do is to make the overall structure of the aircraft a little stronger, and then you can install a multi-barreled cannon on it, or a Gatling or something.

In fact, it is Liu Hai to make a transport plane, and now the mainland will also find a way to install some weapons, just like the last small plane, a heavy machine gun was installed.

"Two months outside, that's the equivalent of 16 years." Bangs look at the stem of a thumb-thick ginseng.

The things in the space of the aircraft carrier, as long as they are not mixed with things from the outside world, are basically not a big problem.

There are also a lot of small ginseng, and these are the ones that this ginseng bred.

Something that has no vitality doesn't have much impact, just like the plane that Bang Hai flew out before, and when it flew back and put it on the aircraft carrier, it didn't have much impact.

But if you take an apple out and wash it, and then put it in and come in again, the apple will either become a dried apple, or it will rot into a black dried apple.

"It's a pity that there is no way to test on animals now!" Liu Hai had to observe the water or something, and then went out of the aircraft carrier space.

The basement of the courtyard is warm in winter and cool in summer, even in winter, the temperature below is still relatively good.

When I arrived at the maintenance department the next day, Liu Hai had just changed his clothes, and Sun Aiguo came.

"Xiao Liu, how are you going to repair the house over there? Will it give you two floors or one floor? Dig the basement or not? Sun Aiguo entered the office and asked.

"Forget about the basement, there is such a big puddle next to it, just build a few houses." Liu Hai didn't say anything about safety, because of his own land, this side is the maintenance department, and the other side is the factory dormitory building, but it is four or five meters wide in the middle of the dormitory building.

"Okay, I'll let the construction department make a plan." Sun Aiguo understood the meaning of bangs, one layer was to not be too conspicuous.

"How's the excavator upgrade?" Sun Aiguo knew that the bangs were on the excavator's side, but he didn't ask specifically.

Ninety model excavator, the country has five factories can produce, the northeast, south, southwest, west, southeast of the five regions each have a factory can produce, and the technical level is getting higher and higher, basically has reached the production technology of motorcycle factories.

However, if you upgrade the excavator, these factories have not been made, and Sun Aiguo knows that the excavator factory in the south began to upgrade the design the year before last, and it has not been successful until now.

"Samples can be released in June or July." Although the bangs feel a little painful, it is better to do the picture yourself, but there are some things that must be done, this time upgrade the excavator belt once, and then upgrade the belt again next time, basically the domestic excavator business itself is not much to worry about.

Now the domestic excavator business started so early, I believe that it can catch up with Europe and the United States and beat them.

Now the domestically produced 90 excavator is squeezing the European and American excavator market, although the market share is pitiful, but it is already considered to be early entry.

Ninety excavators are mainly in third world countries, mainly for bartering, excavators for various minerals, rubber and so on.

Those dealers on Hong Kong Island also don't care that the mainland directly trades with third world countries, because they can do after-sales service and can also sell fuel, because there are no more after-sales service outlets in third world countries, and it is this group of dealers who first built after-sales service outlets.

Europe and the United States began to look down on the consumption power of third world countries, and now it is okay to see the consumption power of third world countries.

But now there is no way to enter, the excavator is not anything else, two or three years on the change, on the mainland now the quality of the 90 excavator with 30 years is also leveraged, and the new type of excavator entry not to say, the number of sales is the after-sales maintenance of this piece, do you want to build your own after-sales maintenance outlets?

Besides, third world countries basically trade goods, but everyone knows how chaotic third world countries are, you just traded with a powerful person today, and you may be ousted by someone else the next day.

It is full of uncertainty, and the market has been occupied by most of it, so those excavator manufacturers in the West can only stare dryly.

The mainland not only said that the excavator price is half bought and half given, of course, it is said that it is so, because it is indeed half cheaper than the market price of the excavator, and it is no problem to recover the cost.

Not only is the price low, but also half buy and half give, but also accept credit, but also accept goods to offset the payment, which Western manufacturer dares to play like this?

Therefore, the 90 excavator looks inconspicuous in the third world countries, but in fact, the sales volume is very large.

Because no matter who comes to power in a third world country, they must first dig up the mine and get the money first, otherwise they will not be busy in vain when they come down in two days.

Gold, copper, and aluminum, all kinds of ores, are shipped to the East by ship, although there is no financial exchange on the surface, in fact, it is the same.

A gang of dealers on Hong Kong Island have made a lot of money after sale, how profitable is the maintenance and after-sales of an excavator, especially in the mine, you can do simple maintenance, but what about parts?

You can go to the big eastern countries to buy it, but two or three months have passed, how many mines do you have to dig in these two or three months?

Sun Aiguo also asked the people from the excavator technology department at first, but unfortunately they said they couldn't do this job.

"That's good, the glass fiber will take about a month, and the natural resin has also been sampled, but it is not very stable." Sun Aiguo also informed Liu Hai of the progress of manufacturing two materials for yachts.

Liu Hai nodded, and Sun Aiguo asked with concern: "I heard that you have stayed up late and worked overtime recently?" Have you eaten the supplements you have eaten? ”

"I gave it to the teacher, my body is so good, I don't need to take supplements." Liu Hai said directly and frankly to Sun Aiguo.

"Next time, I'll find the factory director to get some." After the bangs finished speaking, he was cheeky and took the initiative.

Sun Aiguo smiled at the initiative of bangs: "Okay, but you have to wait until winter to cut deer antlers." ”

"That's fine!"

"What do you think of the rewards prepared by your superiors for porcelain in the future?" Sun Aiguo is also here to ask this question today.

It's mainly the credit of the bangs, I don't know how to solve it, the bangs like porcelain, that's great, and now there are a lot of porcelain in the treasury.

"I obey the arrangement, but the factory director, I don't have to think about my merits or anything, I am a person from the factory, with a high salary." Bangs shook his head and said.

"How can this be the same? Workers also have graded wages, you have such a big credit, it is unreasonable not to reward it, and it is not a small credit. ”

"I am ready to let go of the shield machine production, this piece can be completely independent of a large industry, and there are more units involved." Sun Aiguo talked about another thing.

"I have no problem with this." Bangs wasn't surprised, this super equipment must be manufactured in a separate factory.

"But if there is any problem with this factory in the future, you have to go and ask." Sun Aiguo added.

Liu Hai nodded, and he will definitely stare at the shield machine in the future, especially in the field of automation, in the field of automation in our country in the future, mainly Mitsubishi and Siemens, they have a complete system.

In our country, someone makes it, and no one comes to buy your equipment, and no one comes to learn your system, and it is not easy to do it without market prospects.

As for the subsidy, I believe everyone knows how many doorways there are in this thing.

In fact, sometimes the mainland wishes that the West would block us, because in the blockade field, we have developed very well, and some things used to be occupied by the West, but after being blocked for two years, we have caught up.

Not only did it catch up, but it also made the international market rotten, forcing the other side to pick up the tariff banner to find us trouble.

The simplest carbon fiber, when we didn't make it, how high was the market price?

Our mainland manufacturers saw that it was profitable, and they started it one after another, and after making it, it became the price of cabbage.

This is because after being blocked, there are naturally manufacturers in this huge domestic market to do this.

Take the simplest computer operating system, for example, if this Western company dares to block us and not allow us to use its computer operating system, then believe it or not, many companies will pop up overnight to do this.

I don't dare to say that I am yelling at us in this regard, electrical engineering is also a systematic thing, Liu Hai knows the general direction, and there are relevant books on the aircraft carrier, and it is completely no problem to overtake in corners.

"Are you going to build a twin-engine transport plane?" Sun Aiguo was interested when he saw the drawings on the table with bangs, which was obviously the engine of the plane.

"I'm going to copy C46, I don't know if there's a market." Bangs answered honestly.

Sun Aiguo looked at the drawings and said: "Do it first, no one wants to make it, just use it as a technical reserve." ”

Sun Aiguo felt that there was still a market, because after the last small plane, Sun Aiguo learned about the domestic aircraft market and found that it was still a bit chaotic.

"Thanks to the support of the factory director, my ultimate goal is to make a four-engine passenger plane, which can fit more than 100 people, but I don't know when the wind tunnel will be built." When Liu Hai heard the factory director say this, of course, he wanted to thank the factory director for his support, and at the same time revealed that he had to do bigger things.

The reason why Liu Hai said this is to let the factory director go to the leader to blow the wind and listen to the opinions of the leaders above.

If the leader thinks that there is a problem, then continue to do it, because this is a big plane, not to say that it runs on the ground, and this thing is 100 times more sensitive than running on the ground.

wrote 2,000 words about the little overlord of Southeast Asia, but the audit was not given, and it was changed, speechless.
