Chapter 615 Arrangement (Second update)

Any technology is developed step by step. There is no so-called black technology or alien technology.

Take B2 as an example, its predecessor was XB35, but XB35 used a propeller engine, and then acquired Santoku's HO229. The technical route is clear.

After the three-axis CNC machine tool bangs was made, it was handed over to Gou Rong. Gou Rong first led the technicians in the entire workshop to understand the three-axis CNC machine tool technology.

Then we started to develop four-axis CNC machine tool technology.

Liu Hai serves as the chief technical engineer of the CNC machine tool workshop. It can be said that the four-axis CNC machine tool was made with Gou Rong and others groping and Liu Hai giving guidance.

Now there are nearly 500 technicians in the entire CNC machine tool workshop.

These 500 people are divided into more than a dozen departments, because CNC machine tools involve too many systems, and more technical personnel will be needed in the future.

There are no outsiders involved, except for the workers of the motorcycle factory, who are college graduates from the motorcycle factory.

The Motorcycle Factory University has already opened a CNC machine tool major, and it is foreseeable that this major will become a large department in the future.

The technicians and other workers in the workshop also clapped their hands happily.

The design of the entire CNC machine tool is inseparable from calculation, and every system is inseparable from calculation.

This is why Liu Hai wants to build a supercomputer. If there is no supercomputer, I don’t know how long it will take the CNC machine tool workshop to complete the design.

The workers and technicians below also applauded when they heard the factory director's speech, and Liu Hai also applauded.

"After four-axis CNC machine tools, there are five-axis, six-axis, seven-axis, eight-axis, or even nine-axis and ten-axis machines. In addition, there are four-axis linkage CNC machine tools and five-axis linkage CNC machine tools, which means multiple axes are linked to each other."

Of course, the turboprop engine manufacturing workshop also has the largest territory.

Besides, with bangs here, Sun Aiguo is not worried about the success of the project at all.

Gou Rong was also overjoyed when he heard Liu Hai talking about building a supercomputer. With this, he could greatly speed up calculations.

Which parts require nine-axis real-axis machining equipment or multi-axis linkage equipment? The amount of calculation will be terrifying.

"Liu Gong, I understand." Gou Rong felt dizzy when he heard these terms coming out of Liu Hai's mouth.

Sun Aiguo has long known that the four-axis CNC machine tool will be tested recently.

"Liu Gong, I understand!" Gou Rong nodded.

"Next step, I plan to build a supercomputer in our factory, so that you don't have to worry like last time when doing calculations."

"Okay, okay, I'll give you the credit." After Sun Aiguo arrived, he demonstrated it again, and Sun Aiguo said happily.

"Our technology is still far behind foreign technology. As the person in charge, you must always warn yourself about this!" Liu Hai called Gou Rong aside, mainly to pour cold water on this guy.

It depends on whether the design parameters are consistent before and after. As for why the design parameters of this place must meet this requirement, people in the technical department can only slowly understand the technology inside.

"However, manual programming and calculation can train people, and programming will become a huge subject in the future." Liu Hai continued.

"If it is further subdivided into CNC equipment of different materials, the future of this industry is very broad. Of course, the difficulty will become more and more difficult as it goes forward."

Of course, Liu Hai feels that if he plunges into the CNC machine tool industry now, he will achieve results.

"I hope everyone will continue their efforts and strive to surpass foreign countries one day."

Gou Rong nodded at Liu Hai's encouragement: "Thank you, Liu Gong, for your encouragement."

After the factory director left, Liu Hai called Gou Rong aside.

Because there is no need, everything is led by Liu Hai, and others have to take the initiative to be inspected even if the factory director comes.

"You can report the good news to the factory director." Liu Hai nodded. CNC machine tools involve too many things, and with the development of information technology, the development is getting faster and faster, and there are more and more types of development.

After getting the report, he hurried over. It was almost the end of the year. As the director of the factory, Sun Aiguo had a lot to do.

Liu Hai left the four-axis CNC machine tool workshop and came to the cold outside.

In addition, there are the operating speed, stroke and so on of the spindle.

Liu Hai went directly to the technical department and handed over the design parameters of the cabin to the technical department half a month ago.

"After the four-axis CNC machine tool is mass-produced, we will establish a five-axis CNC machine tool and a four-axis linkage CNC machine tool as soon as possible. Then write a plan for me to review." Liu Hai patted Gou Rong's shoulder again. Five-axis CNC machine tools are not so easy. Although there is not much difference between four-axis and five-axis, in terms of calculation and programming, it is a leap forward.

"This means that the distance between us and similar foreign products is getting smaller and smaller."

Whether it is the host, driver, auxiliary, programming and other ancillary facilities, all need to be calculated.

Of course, their review is not a redesign.

Liu Hai was not very proficient in this area and could only know the general direction, so he could only control the general direction.

Even the flow rate of the coolant and the various components related to the coolant need to be calculated. This does not mean that just installing a coolant system is enough.

"Understood!" After hearing this, Gou Rong no longer felt the same joy as when the factory director praised him just now. He was only thinking about the four-axis CNC machine tools and the five-axis CNC machine tools. After all, he had to write a plan.

Then Sun Aiguo delivered a speech.

"The four-axis CNC machine tool is the most advanced CNC processing equipment in China."

Liu Hai came to the turboprop engine manufacturing workshop again. This may be the most confidential workshop in the motorcycle factory. Only Liu Hai can easily enter and exit here without any inspection.

There was definitely no time to do other things, so Liu Hai supported Gou Rong.

The technical department here did not blindly design based on the design parameters provided by Liu Hai, but reviewed the entire design parameters.

Winter in Kyoto is like this. It's already mid-December, and 12 is about to come to an end.

"Gong Liu!" Seeing Liu Hai coming, the people from the technical department hurriedly greeted him.

There are hundreds of people in the technical department here, and they are divided into many departments because there are many systems on the aircraft.

"How's it going?" Liu Hai asked when he saw the person in charge coming.

"We have reviewed the calculation results of the parameters and have begun the design."

"How long does it take to design the aircraft girder?" The aircraft girder Liu Hai mentioned is not the car girder in the traditional sense. The girder of the aircraft is round. The girder near the wings is relatively close to each other, and the rest of the girder is far apart. farther.

Students who have flown on commercial airliners may have discovered that there is a gap between some first class and economy class cabins, and there are two doors. This place is the beam of the aircraft, which is a complete circle. This beam of the aircraft requires a very large casting press.

Of course, before there is a super large die-casting machine, this beam can be broken down into several pieces.

In other words, the circular girder is divided into four or six pieces for assembly.

However, the safety of this kind of assembly is relatively low, because the pressure-bearing capacity, tensile resistance, and earthquake resistance of this assembly are not as good as those of the integrated structure, and the material strength itself is not as high as that produced by super-large die-casting machines. .

It is also a necessary equipment for manufacturing medium-sized military transport aircraft and ultra-large transport aircraft.

As for where the beams are located on the aircraft, generally speaking there is one at the nose, then one at the front and rear of the wing, one on the wing, and finally one at the tail.

To put it bluntly, these aircraft beams are used as the stabilization system of the entire fuselage.

Because the forces near the wings are relatively large, the girders here are relatively close to each other.

This is also the first time Liu Hai has introduced this aircraft girder concept, laying the foundation for the design of future large transport aircraft and super large transport aircraft.

"According to the planned progress, it will take one and a half months." The person in charge said.

"Yeah!" Liu Hai nodded and made some calculations. If the first design is completely up to standard and the drawings are sent to Southwest Second Heavy Industry for mold opening, it is estimated that the parts can be seen within 6 months.

This kind of girder is not of uniform size, because different equipment needs to be installed at different positions. The girder in the middle wing also needs to be installed with wings. Therefore, the position must be reserved in advance when designing. Then when making the mold, Molds of different specifications must also be made.

Also, the size of each place is different, so the data of this girder is also completely different.

Of course, these molds will not be wasted after being manufactured, because it will be faster to have these molds when the aircraft is mass-produced later.

In fact, the actual casting time of parts is not very long, just like it only takes 15 seconds to cast an airplane landing gear.

The ultra-large casting press can also save material weight. For a single aircraft beam, it can reduce the weight by more than 15%.

The same is true for the landing gear. The weight difference between the landing gear manufactured by a large die-casting machine and the landing gear manufactured by ordinary machines can reach 18%.

In addition, the same is true for the wings. If the main beams inside the wings are made using a die-casting machine, the safety and service life are much higher than those made by other methods.

This is why in the subsequent manufacturing of large aircraft, only a few countries in the world were able to manufacture them.

Because without the die-casting machine, the safety of the aircraft would be reduced to a very low level.

Liu Hai knew that in history, it seemed that the Yunshi was due to the splicing mode used in the main beam, which caused many problems during the flight. In addition, the other partner who was cooperating at the time had to cancel the big plane due to the relationship between the two countries.

In fact, to put it bluntly, the master dropped his skills and ran away before we learned it. It was the same thing with Fat Bear back then, and he ran away after teaching us half a skill.

As an apprentice, I wanted to continue this project but was unable to do so, so I had to give up.

In this world, Liu Hai pushed forward the factory director's suggestion early on and built a die-casting machine. Of course, from a profit perspective, this equipment is actually a loss because this equipment spends a lot of time idle.

But you can't talk about the relevant personnel and let them go home on vacation when they are free.

"Design the simplest one first." Liu Hai pointed to the beam at the nose of the machine.

This beam is located at the turning point where the nose and the fuselage connect.

The main thing is to give this design to Erzhong first so that they have something to do.

"Understood!" The person in charge nodded.

"If you have any questions, come to me!" Liu Hai didn't go to see their designs in detail. Anyway, he wanted to show the designs to himself after they were completed.

Then Liu Hai looked at the time and got ready to get off work, because Liu Hai still had to calculate the parameters of the wings and landing gear and then take them out.

Of course, there are some things that Liu Hai is not prepared to calculate by himself, such as the loading system of the warehouse.

As mentioned earlier, the cargo hold of this transport aircraft adopts an upper and lower two-piece structure.

When loading and unloading, the lower piece directly forms a slope. There is something similar to a winch inside the cabin. As long as the goods are placed on the slope, the goods can be pulled directly into the cargo warehouse through the winch.

When unloading, you can also use this slope to drag the goods directly out of the warehouse.

This is a relatively simple system for bangs, so there is no need to do it yourself.

Let the people in the technical department train themselves.

All you need to do is review the final design.

Liu Hai had just returned to the maintenance department and was about to get off work when Sun Aiguo came again.

"Director, what's the matter with you?" Liu Hai was a little surprised. They had just met him not long ago, and he didn't say anything just now.
"The West wants to issue airworthiness certificates and flight licenses to our twin-engine turboprop transport aircraft!" Sun Aiguo nodded and then said.

"Uh!" When Liu Hai heard this, he knew what the Western guys were planning. Didn't they just want to see the data of our twin-engine turboprop transport aircraft?

"What do the higher-ups think?" Liu Hai asked.

"The higher-level department wants to hear your thoughts." Sun Aiguo couldn't say, and the higher-level department couldn't make up its mind either.

The higher-level department does not make decisions by one person, but by many people, and everyone has their own point of view.

Some people think that they can obtain Western airworthiness certificates and flight permits, and then sell such aircraft all over the world.

Some people think that this is our country's most advanced transport aircraft, so it is inappropriate to open it for others to see.

"I personally think we can get the airworthiness certificate and flight permit. Our large aircraft prototype may be released by the end of next year." Liu Hai is giving Sun Aiguo a heart-warming pill.

"Also, handing the Yunba to the West to issue airworthiness certificates can muddy the waters. I think Niu Niu's new aircraft carrier will definitely need carrier-based transport aircraft."

"The future aircraft carriers of Gallic Chicken will also need carrier-based transport aircraft." Gallic Chicken has also recently announced its aircraft carrier manufacturing plan. Liu Hai feels that the reason why Gallic Chicken does this is entirely because of the cow next door.

I don’t care if others have it, but I can’t have it next door. I must have what the next door has, and I don’t have what the next door has. Doesn’t this mean that I am inferior to the next door?

Although Luji's parliament is also a bit defeated, the men in the parliament will not be at a disadvantage when comparing it with Niu Niu next door. After all, you earn your own face. Niu Niu has two 80,000-ton aircraft carriers, so we are not as good as The other party? Can't we have it?
And after Liu Hai waits for this big plane to come out, he will see if there is a chance to cooperate with Gaul Chicken to add some strength to Gaul Chicken.

In fact, by transfusing the blood of cows and Gallic chickens, the fat bear can be restrained now. When the fat bear collapses, the bald eagle can be restrained. Of course, the speed must be controlled very well. Don't let the bald eagle and the fat bear think that these two guys can threaten them. to myself.

In fact, the Gallic Chicken at this time is considered to be at its peak, because the West African King at this time is the real King, unlike Liu Hai who was just a street rat in West Africa when he traveled through time.
