Chapter 346 Upgrading the Excavator (Second Update)
Liu Hai came to the excavator production workshop to upgrade the excavator, mainly to see the technical level of the people here.

In fact, the excavator itself is not complicated. Especially in motorcycle factories, with the existing power technology and hydraulic technology, what is needed is how to integrate resources.

"Upgrading an excavator is actually very simple, it just requires calculation!" Liu Hai said while discussing with a group of people in the technical department of the excavator workshop.

"Chief Liu, the calculations involved are too complicated, and the force changes of each structure." The chief of the technical department said.

Liu Hai nodded. The main reason is that the knowledge of these technicians is so poor. Even if they are college graduates, it is impossible to design an excavator alone.

Not to mention current college students, even college students in 2020, it will be very difficult for them to design an excavator.

Each system of large machinery requires constant calculations, constant optimization, design changes, and constant testing.

"I know this is more difficult, but everything can be done. This time I will lead everyone to upgrade our excavator, so that everyone can learn something from this upgrade." Liu Hai happened to have these few days. It's a free time, so I'll guide the technical department here to upgrade the excavator.

The yacht thruster was completed, the rest was not in place yet, and the moldings in the wood shop were barely completed.

The transport aircraft Liu Hai is planning to copy the C46, ​​which is also the main force on the hump route and can easily land on the plateau.

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

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

Then design based on these parameters, hydraulic motors and engines can be used off-the-shelf.

The rest is the chassis, hydraulic control system, and the big and small arms of the excavator.

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

Only when these people from the real technical department designed new excavators did Liu Hai realize how poor the current technical talents are.

These people in the technical department can be said to be the most educated in the factory, but they still make Liu Hai feel heavy when doing some calculations.

This is the reason why the overall level is low. Of course, even in modern times, those who can independently design excavators are considered talents among talents.

The bangs mainly serve as a guide to let those in the technical field know what steps they need to go through if they want to redesign an excavator.

After this experience, the future will be much better, but the subsequent excavators will also involve computer control issues, which is another major technological and qualitative leap.

The intelligent system of excavators before Liu Hai crossed was already very advanced, and there was no such complicated operating lever as now.

In his spare time, Liu Hai looked through the turboshaft engine information given by his superiors. On the one hand, he accurately understood the manufacturing technology of this era, and on the other hand, it was also for others to see.

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

Material technology is mainly about material crystallization, not to mention design.

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

Of course, the main reason is that the North American upstarts have rested on their laurels for so many years. The North American upstarts have been equipped with the F119 engine for many years, but a new model has not been released.

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

Mainly because their military-industrial complex has discovered that the world structure is already like that. It is basically impossible for several superpowers to go to war. After all, everyone has mushroom bombs in their hands.

As for fighting other countries, you don't need anything too advanced at all, what you have is enough.

This has resulted in the military-industrial complex not investing much in the research and development of new products, and most of the money basically goes into everyone's pockets.

The F35 has deceived many countries. It was said to be very awesome at the beginning, but after it came out, it exposed too many problems, so that it was grounded for half of the year.

In fact, the f35 had a fatal flaw from the beginning, which was the short legs inherited from the f22.

This is also the consequence of the dominance of one American arms dealer. After these arms dealers got the money, most of them returned, and the remaining small amount of money was used to tinker with it, make a big pie, and then say it failed.

而且后面看看f18还有f15改进了多少型号，F18甚至最后采购价格单价已经达到9000多万美金差点上亿，每小时飞行成本更是3万多美金，当初嫌弃F14飞行成本贵结果现在比别人更贵。

There is also the continuously improving F15. The military purchase price of an aircraft is 1.7 million US dollars, while the export sales reach 4.2 million US dollars, and the flight cost is [-] US dollars per hour.

So where the military spending goes, you can see at a glance. Where there is more military spending to upgrade equipment, it is all based on the original repair. I feel that this model is not worth the money, so I will upgrade to a new model immediately. , the research and development expenses are a large sum, and the flight cost of the new fighter will definitely increase. In the future, it is not surprising that the flight cost of the most powerful F15 in the universe will be [-] US dollars per hour.

What exactly do these upgrades do?It’s not other people who have the final say. Anyway, there is no equal opponent to fight against. Bullying those small countries can’t tell the level at all.

Liu Hai has no shortage of materials and technology. Liu Hai has been doing this all his life. However, Liu Hai still has some shortcomings in design, so Liu Hai needs to think carefully about the helicopter engine on the aircraft carrier first.

Try to build a general-purpose helicopter for the mainland.

"The upstarts in North America will probably be confused when the time comes. If they produce a new fighter jet, the other party will soon produce a similar one, or even more advanced than us." Liu Hai is very much looking forward to the fact that after the honeymoon period, the upstarts in North America will fall out with us. Just like Big Brother in the north, he has clearly removed the experts, but others have developed better. What kind of logic is this?

Shouldn't I remove the experts, and then they will finish industrialization and kneel on the ground and call us daddy, begging us to garrison troops at their house or something?

Big Brother in the North is currently riding a tiger.

It was so refreshing when I fell out, but now I feel like constipation.

Moreover, the big brother in the north also dug holes for the little brother next door. At first, he encouraged a country in the South Asian subcontinent. After a rainbow of lies, the country could no longer find the north. Then, the neighbor next door almost launched a battle to defend the capital. Anyone with a discerning eye could see it. It can be seen that this country in the South Asian subcontinent is finished.

Of course, the other two superpowers do not want to see the industrialization of the countries in the South Asian subcontinent. Although they offer loans for industrial equipment, they do not want them 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 South Asian subcontinent countries, with enough population and enough industry, are also a potential threat to the two big brothers. The best situation is to be half-dead now.

It's just that the fighting ability of the neighbor next door is a bit abnormal. Last time, 17 gangsters were beaten. This time, 17 gangsters didn't dare to leave. They only dared to encourage some idiots. As a result, this idiot almost lost the capital.

This big brother also supported the younger brothers from Southeast Asia to form the East Asia Alliance as the leader. Unexpectedly, before the younger brother next door was anxious this time, the guy from North America jumped out first.

Originally, the big brother in the north wanted to drag the little guy next door into the war, and he would stop as soon as the little guy next door entered the scene. Unexpectedly, the little guy next door didn't even enter the scene. Where was the courage you had to fight 17 back then? Do you want to do it again?

The little brother next door now has super mushroom eggs and flying bricks. The key is that the opponent's industrialization strength is no longer weak. The big brother in the north is now crazy and has no choice but to encourage the new overlord in Southeast Asia to accuse the little brother. Unfortunately, the little brother Throw it to some junk that he sold himself to before.

Liu Hai in Kyoto knew from the radio and newspapers that Big Brother was a bit untrue.

Liu Hai considers more the international situation and the overall industrial strength of the country.

We won't come up with too advanced helicopters now, at least we have to wait until Big Brother North America goes to visit Big Brother North America during its honeymoon period.

Because the aircraft industry involves too many technologies, even if Liu Hai continues to borrow technologies from outside, he will not be able to come up with an overall technology in more than ten years.

Then we can only take advantage of the honeymoon period to find a way to learn as much as we can by then, and we will not lose anything we can buy with money.

"The current overall strength in China is to use propeller aircraft first."

"Cheap, durable and easy to use." Liu Hai saw clearly that he would not engage in those high-end gadgets. 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 meaning of it. They just talk about speed and height. It is easy to say things but difficult to do things.

Liu Hai now has to go to one more workshop every day, that is, the excavator workshop. He spends two hours a day in the technical department of the excavator workshop.

Then there are several sports car workshops, and occasionally the shield machine production workshop.

"Big Brother North America, please help us get the chips out as soon as possible." Liu Hai looked at the industrial machines in the factory, looking forward to the stars and the moon, waiting for the chips from Big Brother North America.

It's not that Liu Hai doesn't want to work on chips, it's that he doesn't have the opportunity to intervene and doesn't understand. Liu Hai really doesn't understand this stuff, but he understands the application of chips.

Of course, we also understand the general direction of future development, which is huge. As long as we don't go the wrong way in the general direction, overtaking in corners will be very easy.

The C46 transport aircraft can be said to be a classic of World War II, with a maximum flight altitude of more than 8100 meters, a range of 1900 kilometers, and a load of 4.5 tons or 28 people.

This was developed by the United States in 1940. Of course, there have been improved models in the future. It has been a full 26 years since now, but it still has a lot of use in China.What Liu Hai has to do is to make the overall aircraft structure slightly stronger, and then install multi-barreled cannons or Gatlings on it.

In fact, Liu Hai is used as a transport plane. Now the mainland will also find ways to install some weapons. Just like the last time the small plane was equipped with a heavy machine gun.

"Two months outside, this space is equivalent to 16 years." Liu Hai looked at the ginseng stem as thick as his thumb.

As long as things in the aircraft carrier space are not mixed with things from the outside world, there is basically no big problem.

There are also many small ginsengs, which were bred from this single ginseng.

Things without vitality do not have much impact, just like Liu Hai's airplanes that flew out before and flew back and put them on the aircraft carrier have little impact.

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

"It's a pity that we can't conduct animal testing now!" Liu Hai had no choice but to observe the water and so on, and then left the aircraft carrier space.

The basement of the courtyard is warm in winter and cool in summer. Even in winter, the temperature down here is still relatively good.

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

"Xiao Liu, how are you going to repair your house later? Are you going to build two floors or one floor? Are you going to dig a basement underneath?" Sun Aiguo asked as he entered the office.

"Forget it about the basement. With such a big puddle next to it, you can just build a few houses." Liu Hai did not mention the safety issue, because on his piece of land, one side is the maintenance department, and the other side is the factory dormitory building. , however, there is a width of four or five meters between it and the dormitory building.

"Okay, I'll ask the people from the Construction Department to make a plan." Sun Aiguo understood what Liu Hai meant, and it was partly to avoid being too conspicuous.

"How is the upgrade at the excavator?" Sun Aiguo knew that Liu Hai was at the excavator, but did not ask specifically.

There are already five factories in the country that can produce the [-] model excavator. There is one factory in each of the five regions of Northeast, South, Southwest, Western Region, and Southeast. The technical level is getting higher and higher, and it has basically reached Production technology of motorcycle factory.

However, when it comes to upgrading excavators, none of these factories have done it. Sun Aiguo knows that the excavator factories in the south started upgrading the design two years ago, but they have not succeeded yet.

"We should be able to produce samples in June or July." Although Liu Hai feels a little sore, he might as well do the drawings himself, but there are some things that must be done. This time, he will upgrade the excavator once, and then upgrade it again next time. Basically I don’t have to worry much about starting the domestic excavator business.

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

Now the domestically produced Jiuling excavator is squeezing the market of European and American excavators. Although the market share is pitiful, it can be regarded as early entry.

Nine-zero excavators are mainly used in third world countries, mainly bartering, using excavators in exchange for various minerals, rubber, etc.

The dealers on Hong Kong Island don’t care about the mainland trading directly with third world countries, because they can do after-sales service and sell fuel, because there are no more after-sales service outlets in third world countries. This is where the after-sales service outlets were first built. A bunch of dealers.

Europe and the United States began to look down on the consumption power of third world countries, but now they think that the consumption power of third world countries is okay.

But now there is no way to enter the market. Excavators are not like other things. They need to be replaced every two or three years. The quality of the current 30 excavator in the Mainland will last [-] years, and not to mention the new types of excavators entering the market. Sales volume is about after-sales maintenance. Do we need to build our own after-sales maintenance outlets?

Moreover, third world countries basically trade goods, but everyone knows how chaotic third world countries are. If you just made a deal with a powerful person today, you might be ousted by someone else the next day.

It is full of uncertainty, and most of the market has been occupied, so Western excavator manufacturers can only stare.

The mainland not only says that the price of the excavator is half-price, half-free, but of course it is said to be so, because compared with the market price, it is indeed half the price, and there is no problem in recovering the cost.

Not only are the prices low, they also offer half-buy and half-free products, and they also accept credit and goods as payment. Which Western manufacturer dares to do this?

Therefore, the [-] excavator may seem inconspicuous in third world countries, but its sales volume is actually very large.

Because no matter who comes to power in third world countries, they must first dig into the mines and get the money first. Otherwise, if they step down in two days, their work will not be in vain.

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

A bunch of dealers in Hong Kong are making a lot of money from after-sales service. How profitable is the maintenance and after-sales service of an excavator, especially those who work in the mines? You can do simple repairs, but what about the spare parts?
You can go to the big Eastern countries to buy it, but two or three months have passed. How much ore will be mined in these two or three months?
Sun Aiguo also asked the people in the excavator technical department at first, but unfortunately they said they couldn't do the job.

"That's good. Glass fiber will take about a month. As for natural resin, samples are also available, but they are not very stable yet." Sun Aiguo informed Liu Hai of the progress of two materials for manufacturing yachts.

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

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

"I'll ask the factory manager to get some next time." After Liu Hai finished speaking, he shamelessly asked for it.

Sun Aiguo laughed at Liu Hai's initiative: "Okay, but you have to wait until winter to cut the deer antlers."

"no problem!"

"Your superiors are planning to replace your future rewards with porcelain. What do you think?" Sun Aiguo also came to ask this question today.

Mainly due to Liu Hai's side, I still don't know how to solve it. Liu Hai likes porcelain, so that's great. There are a lot of porcelain in the treasury now.

"I obey the arrangement, but the factory director doesn't need to consider my merit or anything. I am originally from the factory and earn a high salary." Liu Hai shook his head and said.

"How can this be the same? Workers still have graded wages. You have done so much, so it makes no sense not to reward you. It is not a small achievement."

"I am ready to let go of the shield machine production area. This area can be a large industry on its own, and there are many units involved." Sun Aiguo said another thing.

"I have no objection to this." Liu Hai was not surprised. This kind of super equipment must be manufactured by a separate factory.

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

Liu Hai nodded, and he would definitely have to keep an eye on the TBM in the future, especially in the field of automation. In the future, the field of automation in our country will mainly be Mitsubishi and Siemens. They have a complete system.

Even if someone makes it in our country, no one will buy your equipment or learn your system. Without market prospects, it will be difficult to handle it.

As for subsidies, I believe everyone knows how many ways there are.

In fact, sometimes the mainland wishes that the West would block us, because in the blocked fields, we have developed very well. Some things were previously occupied by the West, but after being blocked for two years, we have caught up.

Not only did we catch up, but we also ruined the international market, forcing the other side to raise the banner of tariffs to cause trouble for us.

The simplest carbon fiber, how high would the market price be before we made it?

Seeing that it is profitable, our mainland manufacturers have launched their products one after another, and after making them, they sell them at cabbage prices.

This is because after being blocked, the huge domestic market naturally has manufacturers to do this.

Take the simplest computer operating system as an 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 dare not 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 related books on the aircraft carrier. If you want to overtake in a corner, it is absolutely no problem.

"Are you planning to build a twin-engine transport aircraft?" Sun Aiguo became interested when he saw the drawings on Liu Hai's table. This was obviously the engine of the aircraft.

"I'm planning to imitate C46. I don't know if there is a market for it." Liu Hai answered honestly.

While looking at the drawings, Sun Aiguo said: "Do it first. No one wants it when it is done. 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.

"Thank you to the factory director for your support. My ultimate goal is to make a four-engine passenger aircraft that can carry more than 100 people. I just don't know when the wind tunnel will be built." Liu Hai heard the factory director say this, and of course he wanted to thank the factory director for his support. Support, while revealing that he has bigger things to do.

The reason why Liu Hai said this was to ask the factory director to go to the leaders to talk to them and listen to the opinions of the leaders above. If the leaders felt that the work was not done and would not allow it to be done, then they would not do it themselves.

If the leader thinks there is something wrong, then continue to do it, because this is a big aircraft, not just one that runs on the ground. This thing is 100 times more sensitive than one that runs on the ground.

　I wrote [-] words about the Little Bully in Southeast Asia, but the review failed and I revised it again, leaving me speechless.
