Shuttle To Get Rich Since 1985

Latest website: Large forging presses are divided into die forging and free forging. The technical level of die forging is higher than that of free forging.

Die forging is forging and forming in a nearly closed space, which requires strong equipment capabilities.

Free forging is local deformation. Through the upper and lower anvils of the press and related accessories, the metal is gradually forged into the required shape.

The large aircraft that was tested in the mainland in September 1980, because of the lack of large-scale forging press equipment in the country, the aircraft girder was forged in sections and then spliced ​​together. After 180 hours of flight, experts from various fields conducted research on the overall safety performance of the aircraft. The evaluation failed to meet the requirements for mass production, and later because of the hostility between China and the United States, technology and other sources were also lost.

The reason why Airbus was able to compete with Boeing in the early days was because the 65,000-ton forging press equipment purchased by France at that time allowed Airbus to share the market with Boeing, and the French forging press equipment was purchased by Mao Xiong in 1976 , 65,000 tons of hydraulic presses.

Back then, Mao Xiong produced 75,000 tons of forging press equipment, so Mao Xiong was able to produce large aircraft in the 1980s, but it took 15 years for our country to have 80,000 tons of forging press equipment.

He Gui didn't know what happened to Xifei, but he had already conducted a search for related technologies in 2002, and then carefully looked at the technology-related things here. Bai'an Aircraft Company adopted It is also a 70,000-ton forging press equipment, which can be said to be higher than that of Airbus.

Many of the forging parts used in large passenger aircraft are very durable. The wing spar of the main beam of the aircraft, and the landing gear all need this kind of large forging machine, because only the parts forged by this kind of forging machine can meet the performance and requirements. Therefore, the manufacture of large aircraft does not refer to a single technology. The aviation industry is known as the pearl of industry. This is no joke.

-------------modern----

After understanding the relevant technologies. He Gui has returned to modern times. Since the girders have not returned, the skeleton connecting the girders can also be manufactured. He Gui has related equipment here. The design of the skeleton connecting the aircraft girders also combines the force and The welding parts are all staggered, which is carefully calculated, so that the overall bearing capacity of the aircraft reaches a balanced level, that is, the gravity of these passengers should be evenly borne by the entire aircraft.

You must know that civil aviation airliners take off and land many times a day. People who have bought long-distance airline tickets may sometimes encounter this kind of question. For example, from A to B, it does not fly directly from A to B, and sometimes there will be Go to C and D for a lap, so the number of take-offs and landings of civil aviation aircraft is very high. The requirements for the overall bearing capacity of the aircraft and the bearing capacity of the landing gear are very high. The self-weight of the aircraft is also tens of tons. These tens of tons of big guys take off and land frequently every day, so there must be no flaws in the force-bearing part.

He Gui is also very curious about the hundreds of thousands of tons of forging press technology, but unfortunately he can't inquire about these things more. You must know that the range of forging press technology is too wide, from under the water, above the water, and then to the air , These things are needed in space. Take the Shenzhou series of spacecraft as an example, there is absolutely no way to manufacture them without forging press technology.

Moreover, the super forging force will also change the performance of the metal under huge pressure.

He Gui's girders are not in place, and they are not idle. The frame connection structure of the aircraft girders also needs a lot. He Gui's processing technology in this area is not a big problem. First, the materials are smelted.

It is to shape the material, and heat treatment is required after the material is formed, so that the performance of the material can meet the requirements. This is also a very complicated process. These aluminum alloy components must not only have sufficient strength, but also need sufficient toughness, so The metal ratio and heat treatment process inside require very superb technology.

Of course, the price of these materials is not cheap, and there are many rare metals added in them.

In fact, He Gui was not in a hurry. The manufacture of the girders was not a big problem. It is estimated that there were some mistakes in the forging process. After all, several girders had to be forged this time, a new process and a new part. , It does not mean that it is qualified when it is manufactured, especially for mold forging. Maybe there will be problems of one kind or another in the finished product manufactured in the middle, and the follow-up can only continue to further optimize the mold and related processes.

Anyone who has worked as a fitter knows that it is not so easy to make molds. It is impossible to succeed at one time, and it needs continuous modification and optimization.

What's more, it is understandable for this kind of super-large forging die to have such and such problems. Anyway, He Gui still has a lot of things to do, and the connection structure between the girders has to be processed. The processing of the spar also requires considerable technology.

The entire aircraft relies on the engine under the wing to provide thrust, so the wing's bearing capacity requirements are also very high. If you observe carefully, you will find that the wing actually has a large gap when the aircraft takes off and lands. Moving up and down, this actually means that the requirements for overall performance are very high, which is why few countries are able to produce passenger aircraft.

He Gui didn't urge Xi Fei to go there, but Xi Fei got angry in a hurry instead.

Die forging in the forging industry requires high technical requirements and high cost. It is difficult to say that large-scale forging equipment is forged in batches, so the forging of large parts basically adopts the method of free forging, but Xi Fei If you want to take a bite of the dividends of civil aviation airliners for the first time, then the necessity of mold forging is definitely needed. The performance of mold forging is higher than that of free parts.

And everyone knows that as long as one model of civil aviation airliner is finalized, then many models can be derived from this model.

However, the technical level of die forging is quite high, the forging ratio must meet the requirements, and the forging must be thorough. Xi Fei this time has a lot of time and heavy tasks, so in the process of mold manufacturing and forging, various problems have appeared. I have never received such a large order.

The beam with a diameter of 3.7 meters is facing many problems, not only the problem of the mold itself, but also the problem of loading and unloading, and the problem of operating space.

Such a large girder has not been manufactured in China, especially for several types of girders. Although the leader has given the task, the subordinates are also confident in completing it, but in the process of manufacturing, such and other tasks are inevitable.

In the process of die forging, it is required to maintain the overall temperature change range. If the local temperature difference is too large, it will cause many problems during the forming process, causing a lot of local stress or other problems.

In addition, feeding such a large girder is also a big problem. The materials to be loaded must ensure a certain temperature difference. The best is one-time loading. If the one-time loading cannot be completed, then the second loading will face many problems. .

These are some problems that occurred before there was any specific operation. Although Xifei has the ability to solve this problem, it will take time to solve any problem.

Seeing that it has been more than ten days since the scheduled time, the two big heads of Xi Fei are also anxious to get angry, and their mouths are blistered, but the technical problems are one after another. The molding is a whole, and the requirements for molding are Very high, but also the most technically difficult.

After He Gui waited here for a few days, he had an idea in his mind, that is to go and see Xifei's forging technology for himself. You must know that the 75,000-ton forging press there was already the largest model in 2002. For reference, wouldn't it be nice to get a 100,000-ton forging press? Or get a 120,000-ton forging press, which is now on Hyundai's side. The country is already leading the world, so He Gui decided to take a look, not to mention getting the most advanced technology, but getting a 100,000-ton one by himself, and making it the world’s number one in 2002, it’s not easy, anyway. I also have some understanding of forging presses.

Just do what you said, He Gui took Gao Zhong directly to Xi Fei's side, of course he also said hello in advance when he went.

When the two big heads of Xi Fei heard that He Gui was coming, they had no choice but to welcome him.

After He Gui's plane landed, the two big heads came to greet him in person, and said, "Mr. He, I'm sorry, this time we dragged you down."

He Gui shook his head and said: "This is the case with forging and pressing of large parts. How long will it take? It is not terrible to have such and such problems in the manufacturing process. As long as they can be solved, anyway, I have production tasks on my side now. How many more beams are there?" The sky is not a big problem."

Xi flew two big heads, and immediately entertained j He Gui, and then He Gui proposed, let me see how the technology is.

Soon He Gui's side was full of materials. He Gui found that there were still many technical problems encountered in large-scale forging presses. From feeding materials to starting forging, forging and forming cooling, these are all technical problems, especially the overall The control of a large number of die forging temperatures is also the most critical. The other is the segment ratio. The 3.75-meter girder must keep the overall temperature within a controllable range, that is to say, the temperature difference between any two points cannot exceed a certain amount. Once it exceeds a certain amount, the girder may break directly after forming, or Correspondingly unstable structures are formed internally.

Now that they are all here, the two big heads will entertain He Gui well. Who knows that He Gui plunged into the technical materials to learn technology. Fortunately, He Gui learned from Xifei's outdated 100,000 tons Forging press technology, the two big heads also breathed a sigh of relief, as long as Mr. He is not in a hurry, it will be easy to handle, so more information is sent to Mr. He.

In terms of forging machines, the materials of the aircraft company in 2002 are not as advanced as here, so He Gui has no way to tell others what to do, so he really came here with a learning attitude, so he didn't come out to talk or anything.

In addition, He Gui also has time to fly a plane or something. You must know that there are a lot of planes here, and you can also learn a lot about a lot of planes during the process of flying a plane, such as the Black Falcon series fighter jets produced here, the Black Falcon Two models have been developed, Type A and Type B. Type A is mainly for air-to-air combat and air superiority combat, and Type B is more for ground-to-ground missions.

In addition, He Gui also learned that there is another C-type being designed. This C-type is a heavy-duty fighter with two engines and two seats. Although it is not a stealth fighter, it is still very powerful. This is for export to a certain country. Prepared, it is said that a certain country will order more than 100 air-superior twin-engine fighters, and it is best to be able to board an aircraft carrier.

He Gui has learned a lot here, especially the electronic technology of fighter jets is still very advanced in modern times, and the radar technology is not weak. For example, He Gui has learned some systems of the Black Falcon. In addition, here You can also learn about the development direction of other fighter jets in the world, which provides the direction for the development of Bian Aircraft Company.

Moreover, Xifei not only produces aircraft but also ammunition. The more advanced air-to-air troublemakers, air-ground troublemakers, as well as jamming bombs, radiation bombs, etc., make He Gui feel very comfortable here. The leader, responsive to He Gui's request, took He Gui around to visit, because the two felt that there was nothing to keep He Gui secret, after all He Gui produced the most advanced stealth unmanned fighter jet.

In fact, He Gui doesn't need to know the technology in detail, as long as he knows the general structure of the technology, so He Gui felt that it was right when he came to Xifei. Write it down and save it.

He Gui looked at what he had gained here. Technical data about the 100,000-ton forging press, air-to-air technology, air-to-ground technology, radiation bombs, electronic countermeasures, and large-scale long sword series. Attacks against the sea, etc., the long sword series was previously equipped with Liu Ye, and there are various related technologies for fighter jets.

This is the case in a large aircraft factory. He Gui had a great time playing in it, especially the Black Falcon aircraft, which is very enjoyable to drive. The powerful power of this thing after the afterburner is unmatched by ordinary aircraft. With this kind of fighter jet, flying a big white goose plane is like riding a bicycle. Of course, He Gui will not drive this thing too much. How much is the afterburner once? But one must be self-aware.

Finally, 20 days after He Gui came to Xifei, the first qualified girder forged by Xifei came out and passed the inspection. He Gui also participated in relevant inspections. This thing must be inspected and reliable. This is also the first 3.7-meter aircraft girder integrally molded.

It's not that Xifei couldn't make it before, but that the cost of forging such a girder is very high. First of all, the mold and technical personnel need to concentrate on tackling key problems.

However, the demand for this kind of girder is very low, and there is no output at all from the investment. If it weren’t for He Gui this time, it would not have invested so much energy to produce this, because no one needs it after production, and as an enterprise, it still needs to be produced. Pay attention to the ratio of input to output. In fact, many parts on the aircraft adopt the free forging method. The free forging method is flexible and the cost is lower.

Now that the first girder has come out, there is no need for He Gui to stay here, and He Gui has obtained a lot of technical directions in the past half a month, such as the technical direction adopted by a certain model of the most advanced empty trick, These were quite high-end in 2002, and I also learned a lot about the development direction of fighter jets at home and abroad.

The fact that the aircraft is powerful doesn’t mean much, and the supporting ammunition is also quite critical. Although the F14’s 180-kilometer range of air-to-air mischief seems to have never been shot down, I just ask you if you are afraid?

In 2002, our ammunition shortcomings were still quite large, after all, the time for development was limited.

After He Gui copied the technical information this time, he gave it to Xi Fei to open a few laboratories. In the future, he can also produce supporting ammunition there.

He Gui found himself wandering everywhere, and it was very beneficial to think about when he would go to the shipbuilding side for a walk, and there should be a lot of technical reserves there.

————— 2002————

He Gui himself is on the side of Baian Aircraft Factory, and the aircraft factory is still being divided, mainly civil aviation aircraft, and all other civilian aspects are separated, while the military and research parts are kept on the confidential side.

He Gui himself set up several laboratories, the first is the large forging press research laboratory, the second is the air-to-air mischief laboratory, the third is the air-to-ground mischief laboratory, and the fourth is the air-to-sea Mischief laboratory, the fifth is the laboratory of the extended model of Black Falcon.

He Gui has a lot of information in his hands. Sometimes the direction of development or technical information can save a lot of time and cost with just a few words. These laboratories set the development direction, such as the development direction of the mischievous experiment and the development direction of other aircraft, etc.

There is no detailed technology, but in the process of visiting Xifei, the few words of the technicians are also very important. What kind of structure and design is used, such as what kind of stamping engine or engine? As for other things, He Gui memorized every word the technicians said at that time, because every word and every word they said was researched after a long period of experimentation and inspection, not casually. Just talk.

Five laboratories were established in one go, and the personnel inside are also combined from inside and outside. There are some people from the interior and some people from Damao in the north.

He Gui didn't want to say that it would take at least ten years to get rid of the big hairy people in the north. It would take at least ten years to get rid of these people. The development of certain technologies needs to be accumulated slowly. Gui established 5 laboratories in one breath, and still stunned the relevant departments, but the power of the relevant departments in He Gui's side is not very great, at least the relevant departments cannot contact the specific technical information, The relevant departments can only say that they are assisting this side in the confidentiality protection work. There is no way to check the specific technical information involved. Before the specific technical information is formed, the above does not know what He Gui is researching, the specific technology The information will not be given, and the higher-ups will know what technical information this is after the research is successful.

Of course, there is an exception for the cooperative research and development with the above, but this laboratory will study for a while, and will definitely cooperate with the above later.

There is no objection to this point. After all, to be honest, this is He Gui's private factory, and it is good enough to cooperate with confidentiality work, as long as the technology of He Gui's factory is not only world-leading, but also world-class.

These laboratories are all led by He Gui himself, not to say that He Gui will not be managed by Lao Yu, but that Lao Yu will gradually retreat to the second line now, after all, Lao Yu is here at his age, Although the body is still very strong now, the handover of power can begin to be handed over slowly.

In the follow-up, He Gui will increase the management of the heads of each laboratory. In the future, it will belong to that kind of flat management. One-on-one grasping, Lao Yu’s one-on-one grasping model can only be applied in the early stage of construction, and if it is grasped at a later stage, it will easily cause various problems. Fortunately, Old Yu is very upright, and there are not many others in the family. Relatives or something.

Then if another person comes up, although I am very honest, after all, there are many relatives and friends in the family, so in many cases, it does not mean that I am clean, but my relatives may keep things behind their backs.

So in the next step, He Gui will be personally responsible for the management of each department and be directly responsible to the person in charge of each department.

Of course, there is also an overall management, but the power of the management is greatly weakened.

As for what to do with these research institutions after He Gui retires, that's something to think about later.

Next, the candidates for the person in charge of the five laboratories will each write a report on the future development direction and management of the laboratory, and select the person in charge of the laboratory.

The person in charge of the laboratory not only needs technology, but also needs to have a certain level of management, which does not need to be too high, because what He Gui pays attention to is technical strength. In your eyes, you are not a qualified person in charge.

What He Gui pays attention to here is technology, and there is not so much sophistication in management. If anyone tries to engage in sophistication and delays research and development, the entire department will be dissatisfied with this person, because basically every technology has two Two laboratories develop at the same time, whichever laboratory successfully develops will receive generous rewards for research and development, and those that fail will be abolished and transferred to other laboratories, except for the one led by He Gui himself.

After several times of screening like this, the personnel in He Gui's laboratory have been screened to a great extent, that is to say, which personnel are better in technology and execution, and have some academic level, but In terms of research and development and execution, they are not good enough. This kind of company cannot be used as an important backbone force, but can only be used as an auxiliary force.

The salary that He Gui can get for a real person who can be the head of a laboratory is jaw-dropping. The establishment of five laboratories means that there are a large number of people who can be promoted?

After He Gui got the technical direction and management plan written by these people, he chose the person who is close to the future development direction as the head of the laboratory. The reason for this is that every researcher has a good direction , but the prospects of different research directions in different periods are different. In the 1980s and 1990s, some promising research directions were completely cut off later.

The person in charge of the laboratory that He Gui is looking for must be someone who fits with the general direction he has recorded. If he does not fit in with the management, many problems will arise.

It has been several days since the matter was dealt with here, and then a secret meeting was held with the heads of several departments, and then He Gui left Bai'an Aircraft Company, and then went to Kyoto for a walk.

After wandering around Kyoto, I returned to Hong Kong Island. There was nothing serious about Hong Kong Island, but I still went to the headquarters to wander for two days, and then began to live in seclusion.

-------modern-----

On the Hyundai side, the girders on the west and northwest sides have already come out, and He Gui is ready to use his horsepower. After the first girder comes out, the time for the remaining girders will be much faster. As long as the technical difficulty is broken through, There is no big problem after that.

He Guiyi worked overtime to make some accessories, and then waited for the arrival of several girders.

The girders were transported here by land, and the girders were unloaded by the crane, and they were inspected before they were signed for. Then He Gui started to formally assemble the frame of the machine body. This is a huge workload, mainly because the thing is too big and there are too many things involved in it.

The first is the assembly of the fuselage. After the fuselage is assembled, the wings are assembled separately. After the wings are assembled separately, the wings are connected to the fuselage, and finally it is completed.

First of all, the frame of the fuselage, the frame of the fuselage, and the middle part of the girder are more, that is, the distance between the girder at the junction of the wing and the fuselage is relatively close, and the distance between a large number of other parts is relatively long, such as the tail to the back of the wing The distance between the girders is very long, and the distance between the girders in the middle of the wing and the girders in front of the wings should be closer, because the front of the aircraft has a greater bearing capacity no matter when it is landing or taking off.

He Gui still adopts a segmented layout, which is the one that you usually see with compartments between the first class and the economy class. Some are just a piece of cloth curtain, and those are the whole layout.

There is a gap between the first-class cabin and the economy class. In fact, it is a girder. He Gui also installed a girder here, because the stability is higher and the safety is also higher.

This thing is more troublesome than making a large bomber, because the interior of a large bomber is basically empty and there are no facilities.

First, fix the girders according to the distance, and then assemble the structure between the girders. After the structure between the girders is completed, you need to arrange some pipelines and other things. After the pipelines and other things are arranged, they will be the skin of the fuselage. And the assembly of various parts inside the fuselage.

This process is too complicated, and He Gui's daily progress is very low. For example, the discharge of several girder distances took more than two days, and continuous measurement is required, because the subsequent aircraft is in this assembly workshop. There is not much distance, so this must be arranged well, otherwise we will face very troublesome work in the later stage.

Before the assembly is completed, it is very troublesome to move the aircraft. Once it is moved, some key parts may be misplaced, etc. The aircraft can only be moved after the assembly is completed. Otherwise, there may be some uncertainties. factors exist.

After the girder is installed, then it is to connect the various parts of the girder.

After busy work for more than a month, the framework was basically completed. At this time, He Gui decided to ask for support, because the following circuit system, ventilation system, and sealing treatment of the engine room, etc., required a lot of work. For work, since you need to ask for support, you must ask the workers from Xifei to support you. As for what the workers should do, He Gui must be the talker to guide everyone.

Xi Fei did not expect that He Gui would make such a request more than a month later. To be honest, the two big heads felt a little ecstatic.

Why ecstasy? This is tantamount to saying that you are training skilled workers for yourself. If one or two hundred people go to Mr. He's side and install and assemble under the guidance of Mr. He, then when it is produced on your own side, you can produce the first plane faster, and your production progress will be faster. Much bigger.

In the past, some aircraft produced by He Gui, Xifei also encountered various problems during the mass production, but they could not ask He Gui for support, because it would be embarrassing, so many times they encountered many problems and did not worry about it. How to ask, now that Mr. He is going to support in person, then the requirements must be met, of course, the report must be made first.

After the report was uploaded, the higher-ups approved it, and the two big heads on Xifei's side went out in person, bringing more than 100 workers who were proficient in various technical links to Mr. He's side.

I would see that more than 100 people also shook hands with the leader of the team: "Thank you, thank you, the main reason is that there are too many systems involved, and I feel a little powerless by myself."

"Teacher He, I'm your soldier now. Just tell them what to do. If anyone doesn't do well, I'll take care of them." The leader of the team immediately patted his chest to promise.

He Gui opened his mouth and said: "Then you are welcome, I will ask you some things first, and everyone will do as I say."

"Those who are proficient in circuits, please stand over there." He Gui immediately began to direct more than 100 people, and He Gui did not know the names of these more than 100 people, because it was unnecessary.

Those who are proficient in circuits occupy one side, and there are about 10 people, which is enough. He Gui took out a thick stack of materials: "You should read this material first, and then when you assemble it, you can ask any questions." I."

Soon more than 100 people were divided into more than a dozen groups, and these groups took the blueprints one after another.

He Gui first had a small meeting with about 10 people in the circuit system: "Look at this first, first according to the length of each type of wire marked on it, and then which wires can be tied together and which wires cannot be tied together. Tie it together so that it's done first, and then we go straight to the machine and install it."

Most of He Gui's circuit technology still adopts the mode of doing the final installation first. The circuit always has a starting point, a control point, and a use point. As long as you master this and that line, how long is each one? Lines can be tied together, and which lines cannot be combined to form a structure under an overall framework.

The lines involved in the line are very complicated, including control lines, induction lines, signal lines, etc., how long each line is, and what connectors should be connected to each line. There are instructions on the drawing, but sometimes it involves various The link of the device, this involves the specific installation.

He Gui first held small meetings for these 10 or so departments. Everyone who didn’t understand asked questions, such as what things they didn’t understand, and what things they understood. More than 100 people followed He Gui to learn some technologies during the day, and lived here at the homestay at night. , there are dormitories on the homestay side, but there are no dormitories on the farm side.

A week later, various teams began to enter the arena one after another. When these people saw the huge fuselage, they were too surprised. Can this be done by one person? When installing, you can do some preparatory work first. Among them, the circuit system can first assemble wires of various lengths according to the instructions, which ones can be plugged together, and then finally pave.

There are some things that cannot be solved. For example, the air-conditioning system needs to be installed and manufactured at the same time. In addition, there are oxygen systems, etc., as well as fire protection systems.

He Gui is equivalent to being a technical person in charge, guiding these people, the installation of various pipelines, the shielding of fixed pipelines, and so on. When he started, the progress was relatively slow. After all, everyone has just started, but it took a few days to get started. Afterwards, everyone found that it was not very complicated, as long as the drawings were combined with the real objects, they could see how to do it at once.

The leader of the team writes reports every day, because he has to write detailed reports every day for what he has to do every day. At the beginning, the progress is relatively slow. To give pointers, everyone knows what to look at by looking at the drawings, such as the line from which point to which point, which point to which point, and how many connectors to put down. In fact, you are used to seeing these, and it will be fine if you understand them.

In addition, some of the wings were assembled under the guidance of He Gui. The assembly of the wings also involved many problems, including the oil circuit control fire protection and so on.

He Gui also used the personnel from Xifei as cattle and horses, and went to work for fifteen or sixteen hours a day. Anyway, He Gui was also with him, and then he got off work. After that, He Gui returned to the farm, and Xi Fei Datoutou led his staff to live in the B&B. Datoutou wrote a lot of reports every day, because many things had to be reported every day.

After more than 100 people worked for a month, the prototype of the aircraft has appeared, the internal facilities have been installed in sevens and eighties, and the wings have been assembled long ago. The final assembly is waiting, and then the skin.

The assembled wings slowly approached the fuselage under the hoisting of the crane, and He Gui stood here directing, and the wings slowly fit into the reserved position, and then the technicians hurriedly assembled them.

When the two wings are installed, the whole aircraft looks more complete, after the wings are installed. Install the engine, and then connect the engine's wiring and pipelines, so that the internal control system circuit system of the aircraft is basically completed. After a check, He Gui began to debug the internal system, while others Continue to install the skin and some internal facilities.

The debugging of the system is a very complicated process. After all the flight computers are installed, He Gui checks each subsystem and other systems, and the flight system is also completed.

"Apricot"

It has to be said that the test with many people is convenient. He Gui is holding the walkie-talkie while operating the system in the cab, and then the answer from the outside personnel comes from the walkie-talkie to see how the control system is. In addition, there are other oil pump oil circuits, and even the thrust reverser device of the engine and so on.

The installation of the fuselage skin is actually not very difficult, and skilled workers can do it without much education.

Assembly line factories don't need much education, as long as they follow the operation steps.

The installation of the skin took a week, and the interior decoration was basically completed in this week.

The debugging of the system in one week is basically done. In fact, the debugging of the system is mainly to connect with various modern systems, such as the civil aviation flight system, and a series of navigation systems. After all, in 2002 there The docking data of the aircraft is different from what it is now, and there is no major problem with the control system of the aircraft itself.

Of course, the paint is not sprayed, it must be a yellow leather machine. The yellow leather machine is mainly covered with a layer of coating to protect the plane. When more than 100 people came here for a month and three weeks, the plane was finally completed. The next step It's a ground test.

The ground test must be tested at night, because only at night can we avoid spy satellites in the sky or conduct tests on cloudy days.

Maybe it was luck. After the assembly of the aircraft was completed, there was continuous light rain. It was no problem to do the ground taxiing test of the aircraft in such weather. When the huge passenger aircraft was towed out from the assembly workshop by a trailer~www.wuxiaspot. com~ Everyone was shocked. Although the size of this airliner is not much larger than a large bomber, it feels more oppressive.

After the trailer was in place, He Gui began to control the plane and started a series of ground tests. The big heads in West Africa looked at the runway worriedly. Is the 1,500-meter runway enough?

However, He Gui, who is worried about Xifei, doesn't care.

ignition.

First is ignition.

After the ignition is successful, a series of experiments must be simulated after the ignition is successful.

In other places, this kind of experiment is very complicated, but He Gui's side is much simpler, taxiing experiment, flight attitude control experiment.

Three consecutive days of experimentation, He Gui couldn't wait anymore, there were a lot of things in 2002.

"Let's start flying tomorrow morning, and fly to the nearby airport with less fuel first." He Gui said.
