Chapter 657 80,000-ton die forging press

   "Mr. Tang, you guys really made this big guy!" A group of people came to the workshop next door, looked at the huge plane, and couldn't help but sigh with emotion.

  An aircraft of this size has never been built in China! The whole workshop seems to be unable to put it down.

In the development of aircraft, the first is the wooden prototype, which can be made in advance to let people see what it looks like. If there is a problem, it can be modified as soon as possible. Later, it is the metal prototype, J-10. Research and development means directly building a metal prototype. Later, with paperless operations, prototypes are no longer needed, and you can directly build real machines.

  The big guy in front of me was still a little worried about building a real machine directly, so he built a metal prototype first.

"Of course, but we have to thank Mr. Qin for making the metal prototype so quickly." Chief Engineer Tang looked at Qin Tao, very excited: "Back then, if Mr. Get them all for us, our plane will be at least five years late!"

  Zhao Ling looked at Qin Tao, her eyes were full of envy and pride. This is her husband, who single-handedly promoted the development of the military industry in the whole country, which is amazing!

   This Il-76 is a strategic transport aircraft, and my husband can get back the information. In this world, there is nothing he can't do.

"I just got some blueprints. You are the real heroes. You have worked hard in the past few years. Although this aircraft is very similar to the Il-76, it is better than the blue. It is more advanced than Il-76." Qin Tao said.

"Yes, the overall size of our aircraft is about the same as the Il-76, with a length of 47 meters, a wingspan of 25 meters, and a height of 15 meters. However, our maximum take-off weight and cargo box size are larger than the Il-76 , we have designed a maximum take-off weight of 220 tons, the length of the cargo box is 20 meters, and the width and height have been increased to four meters."

The lateral interface agent of IL-76 is smaller, which is 3.46 meters × 3.4 meters. Regardless of the width and height of the Y-20 cargo compartment in front of you, it is only 0.56 meters and 0.6 meters higher than that of IL-76, which is meaningful for transport aircraft with limited space. major. There will be more goods that can be stuffed inside.

"Of course, the most important thing is its wing. We use the most advanced supercritical wing. The aerodynamic efficiency is much higher than that of the Il-76. When we have a more advanced engine, our maximum The take-off weight can also be increased.”

  Engine!

  Zhao Ling has heard the word engine more than once, and she said with emotion: "The engine has always been our weak point."

   "Yes, aero-engines are the embodiment of a country's industrial strength, and we are still very weak in this regard." Qin Tao said, "So, do you want to develop aero-engines?"

  Zhao Ling shook her head with a smile, of course not, since then, she has been by her husband's side. There are deficiencies in all aspects of the country, and her strength alone is small, but by her husband's side, she can play a greater role.

  The husband is a capable person!

  If she had realized this earlier, she would have followed Qin Tao long ago.

   "It seems that the engine of our transport plane must be imitated first, and then self-developed, so as not to be controlled by others." Zhao Ling said.

"That's right." This time without Qin Tao's answer, Mr. Tang replied: "At present, we plan to use Lao Maozi's D-30KP-2 engine for the prototype. Since our H-6 also plans to modify this engine, we We can import a large number of them, but if we don’t want to be controlled by others in the future, we have to survey and imitate this engine. At present, we have already started preparations, and we can use our own engine after the imitation comes out.”

Both Hong Liu and Yun 20 need Lao Maozi’s D-30 engine, so it must be imitated in China. This imitation is Turbofan-18. Because of the use of advanced materials, it is lighter in weight , after slightly increasing the front temperature of the turbine, its thrust also increased from 12.5 tons of Lao Maozi to 13.2 tons.

  However, the imitation is only for emergencies, and it must be self-developed domestically. The self-developed product is WS-20. Compared with the imitation, its thrust has been increased to 14.3 tons, and it can even be increased to 16.3 tons in the later stage.

  However, more important than thrust is its fuel consumption, which is 30% less fuel consumption than the original engine, which increases its range from the original 7,800 kilometers to 10,000 kilometers, which is even better.

  However, this advanced engine cannot be counted on now, because it uses the core engine of the Taihang engine, that is, the core engine of Turbofan Ten. As long as Turbofan Ten fails, this engine will not be produced.

   Now it can only be used for mapping and imitation.

"This all-metal prototype is just a shell, or has the equipment already installed inside?" Qin Tao asked curiously. They didn't go up the early warning aircraft because they were installing internal equipment. So, what about this aircraft now? ?

   "The internal equipment has been installed, everyone can go up and have a look." Mr. Tang said.

  So, a group of people stepped onto the gangway and entered the cockpit.

   "Did you use a glass cockpit?" Qin Tao looked at the monitors in front of the cockpit in surprise. The size of the screens is not small. Every pilot has three pieces in front of them! Isn't this cabin too advanced?

  Compared to Lao Maozi's watch shop, this is simply a cross-age!

"That's right, what we are going to design is a transport aircraft of the world's advanced level, of course we need an advanced glass cockpit, Mr. Qin, you can see it, and there is also a diffraction head-up display, some important data are directly displayed on the head-up display. "

  In the past few years, domestic avionics technology has developed rapidly. These things have appeared on fighter jets, and now they are also transplanted to transport aircraft!

   "This seat is really comfortable." Wu Shengli was already lying on the back seat: "Who uses this chair?"

  Ordinary large aircraft have seats for two people in front, namely the captain and the pilot, but the other personnel are not fixed.

   Now, Wu Shengli is sitting on a chair behind the center console, with armrests on both sides, and can lean back. With no controls on either side, this isn't a mechanic's seat. On both sides of it, there are two folded small seats.

"We use a two-person driving system, so in extreme cases, two people can fly, and the seat in the middle is for the third loader." Mr. Tang said: "The folding benches on both sides can also fly. Seats are prepared for other crew members, of course, during long-distance flights, the middle seat can be folded down into a bed, allowing the crew to take turns to rest."

  This kind of large transport aircraft can fly for more than ten hours, and the crew will be tired. Fortunately, there is no need to prepare diapers like fighter pilots. There is a bathroom in the nose and a simple rest place.

"Two-person system? Two people can fly?" Wu Shengli was a little surprised. He knew that this kind of large aircraft required at least three or four people. The Il-76 of the old man was even a five-person system. Driving system: the captain is on the left, the engineer is behind the middle, and the co-pilot is on the right. There is also a telephone operator sitting behind the three. This buddy has to operate several radio stations at the same time. There was also a navigator.

   Now, this transport plane of our own side can be done with two people?

"That's right, the two-man pilot system has begun to be popularized in passenger planes. The fewer crew members, the lower the operating cost." Qin Tao said: "In the future, all our large planes, including bombers, will use two pilots. One person is enough. The advantage of this is that the training cost of the pilots is greatly reduced. If something really happens, there will be fewer sacrifices. Is it less?"

  Mr. Tang nodded: "Yes, our bomber can also be changed to a two-man driving system."

  The advanced cockpit in the front makes people feel emotional. After watching this, everyone turned to the back and looked at the huge and spacious cargo warehouse.

"After the successful development of this kind of aircraft, our early warning aircraft, refueling aircraft, electronic warfare aircraft, etc. will all have a suitable platform. Now, our technicians must continue to refuel. I remember you once promised that before the new millennium To achieve the first flight, I am optimistic about you." Qin Tao said.

   "Boss Qin, of course we remember our promise at the beginning, but recently we encountered a problem."

   "What problem? As long as I can help, I will do my best." Qin Tao said.

"We need a large die forging press." Tang Changhong said: "Now, this is just a physical prototype, which is used to give us an intuitive impression, so we use a fuselage frame made of ordinary materials. However, if we want to For the official prototype, we need this level of equipment."

  A die forging press is actually a hydraulic press, but since it is called a forging press, its main function is forging, that is, to heat the metal to a certain level, and then put it inside for beating.

  The strength of this beating depends on the size of the die forging press.

  In the world, the 10,000-ton hydraulic press is already very strong. However, in the field of die forging presses, the 10,000-ton class is far from enough.

"In the field of die forging presses, 40,000 tons is a dividing line. At present, the largest in the United States is 45,000 tons, and France is 65,000 tons. Lao Maozi is the most powerful, and their die forging presses are 75,000 tons. "Tang Changhong continued: "Because Lao Maozi's die forging press is the most powerful, the most advanced Airbus A380 airliner currently planned in Europe plans to go to Lao Maozi to process the required parts. The aircraft's fuselage frame, transmission Beams, engine suspension frames, landing gear and other components can only be manufactured with this large forging press."

  Zhao Ling felt nervous for a while. Of course, she knew that without advanced production equipment, there would be no advanced products. If the domestic large aircraft industry wants to develop, it must have advanced parent aircraft.

   "Our Yunshi was also a large aircraft back then. Without this kind of equipment, how did we make it?" Wu Shengli asked.

"At that time, we didn't have such a large die forging press in China, so they changed the processing technology of the structural parts, first used a small die forging press to forge out segments, and then welded them together." Tang Changhong said: "Whether it is a machine The body girder, bulkhead, and landing gear are all made in this way, after all, we also have experience in this area.”

  In China, there is indeed experience. The landing gear of the H-6 is welded, and there are several parts that are not easy to weld. One is commonly known as a toilet, and the other is commonly known as pants. Need to use electrode arc welding, preheat 250 degrees before welding, and use two welding tongs alternately, which is very complicated. However, this is not a big deal. What is even better is repair welding. When cracks appear in structural parts, it is too expensive to replace them, so the method of repair welding is used. This method is quite awesome. No, it was invented by the master craftsmen in China, and the blue is better than the blue.

Lao Maozi’s Il-76 transport plane’s landing gear and other parts were also welded. Therefore, some people who belittled Yunshi criticized the unreliability of welding. Back then, there was no strength to manufacture it. It was really lucky that there was no accident. Like, it is only one side of the word. However, the life of welded parts and the like is definitely not as good as that of one-piece forging.

  Now, the transport aircraft to be built in China is bigger, so welding is no longer possible, and a large die forging press must be built!

   "I'm a little surprised, how come the die forging presses of the Americans are not as good as the French?" Qin Tao asked, he really didn't know about this aspect, after all, they were not used in shipbuilding.

   "Because the French die forging presses are also sold from Ermao, which is the same factory that produces die forging presses for Damao." Tang Changhong continued.

In terms of this kind of basic industry, Lao Maozi is still very powerful. From 1957 to 1961, Ermao's New Kramato Heavy Machinery Factory accepted the task to build two 75,000-ton hydraulic forging presses for the Red Empire, which were installed in Kuibyshev Aluminum Plant and Upper Sarda Titanium Plant.

  These two die forging presses are national treasures in Da Mao’s industrial system, and their volume is also very large: the total height is 34.7 meters, the length is 13.6 meters, the width is 13.3 meters, the foundation is 21.9 meters deep underground, and the total weight is 20,500 tons. The size of the workbench is 16 meters long and 3.5 meters wide. It adopts 12-cylinder 8-column upper transmission, the net height of the mold space is 4.5 meters, and the stroke of the slider is 2000 mm.

   You can tell by looking at the geographical location. After the collapse of the Red Empire, all of them stayed with Da Mao.

  What about France? In 1953, Aesop and Crcout-Loire of France built two 20,000-ton hydraulic die forging presses for the manufacture of aviation aluminum alloy forgings. These were made by themselves. In 1976, the French Oberduwaite Steel Company purchased a 65,000-ton die forging hydraulic press from the New Kramato Heavy Machinery Factory for the production of titanium alloy die forgings and aviation aluminum alloys. Die forgings.

  The French one is still produced by Lao Maozi!

As for the United States, of course they also have the ability to build large-scale die forging presses, but they do not have this motivation, so they can make do with what they have at hand. Their 45,000-ton machine was built in 1955 by the Mesta Heavy Machinery Factory. Built at Alcoa's Cleveland, Ohio plant, it hasn't been done in recent decades. When the Ford class was built, an old die forging press from World War II was unsealed again, so they would not spend a lot of money to re-produce it. Capitalists always have to think about profit.

  Now, after hearing Tang Changhong's introduction, Wu Shengli understood: "You mean, you want to ask Mr. Qin to come forward, go to Er Mao's place, and order one at a cheap price?"

  For this kind of thing, only Qin Tao is the most suitable. After all, he has done well with Lao Maozi and has good friends everywhere.

Tang Changhong was about to nod his head just now, but saw Qin Tao shaking his head: "No, even Ermao's company used to produce a lot of die forging presses, but that's a thing of the past, and now, they don't have this kind of forging press at all. The production capacity is up, and we want to order, but we can’t buy anything after spending money, and it will delay the production of our large aircraft.”

   "Then what to do?"

"We make it ourselves." Qin Tao said: "If Ermao can make it, so can we. We can produce one from Erzhong Machine. Now, the world's largest die forging press is not the old-fashioned Damao's 75,000. tons? Then we will build an 80,000-ton one ourselves!"

   Other Qin Tao didn’t understand, but he remembered that in the world before he came, China had the world’s most advanced 80,000-ton die forging press, which seemed to be produced by Erzhong Machinery, so let’s make it ourselves!

  Tang Changhong frowned: "Mr. Qin, we have already asked, no matter whether it is a heavy machine or a double machine, they said that they have never been built, and they have no technical reserves, so they dare not undertake this kind of production task."

   "It's not difficult. I'll go to Ermao's and invite the blueprints, or the person who designed this kind of machine back then, isn't that all right?" Qin Tao said.

   Production is not dared to be placed in Ermao, but it is still necessary to get their drawings.

  The matter was finalized in this way. In the evening, everyone had dinner at Room 603, accompanied by the heads of various projects. Everyone was more relaxed at the wine table, and all kinds of lofty ideals were talked about.

   "Within ten years, our Y20 will definitely become our important air transportation force! Our strategic transportation capabilities can be greatly supplemented!"

   "This is not necessarily the case. Our ground-effect aircraft may be mature, and your 20-year-old aircraft may be eliminated!"

   "Our bomber still has to work hard, and we have to make a stealth bomber similar to the B-2. If you don't work hard at 603, our Mingzhou Group will start to grab your business!"

  Zhao Ling and Qin Tao had accompanied other people to dinner before, and now, returning to this occasion, I feel very warm.

She didn't speak, just listened, when suddenly, the phone rang, she looked at the message on it, then at Xu Zhengyang, nodded with a smile: "Let me go, as President Qin's secretary, I have to take care of myself. "

  Xu Zhengyang nodded.

  President Qin is going abroad again. As a bodyguard, he has to follow him personally. Then, the domestic matter can only be left to Zhao Ling. Moreover, this is also Zhao Ling's side to show her ability.

   President Qin needs such a good wife.

  The next day, Qin Tao looked at his wife curiously: "Aren't you going to Ermao's place with me?"

   "Yes, there are some minor matters in the capital, I'll take care of them." Zhao Ling said with a smile.

   "What little thing?"

   "I'll let you know when I've dealt with it. If you haven't come back, I'll go to Ermao to find you."

  Qin Tao nodded.

  The capital, in front of a certain court.

"Our Mingzhou Group has obtained a large amount of evidence. This person with the online name Dao Guohuo Long Live received a large amount of foreign funds, and then used these funds to discredit our Mingzhou Group. Today, we are going to testify against the court and the public. In front of you, show these evidences and expose this person's true face! Restore our Mingzhou Group's innocence!" Zhao Ling looked very capable in her professional attire.

   Facing the flashing lights of the reporters, the expression on her face was very calm. After she finished speaking, she walked into the gate of the court.

the other side.

  The mentally and physically haggard rumor-monger also walked in. During this time, the world around him has changed.

  Originally as a college student, he was respected by others, but now, he has become a street rat.

In the academy, the way everyone looked at him changed. The counselor talked to him several times, asking him to bow his head and admit his mistakes, and strive for leniency. However, he still chose to believe in the Internet, and those people on the Internet gave him encouragement. He even said that he is a fighter and a warrior, so he must persevere!

  With such a mood, Long live the island country product walked in.

"First of all, our Mingzhou Group will submit chat evidence. The evidence is very long. Please read it slowly. If the judge allows it, we will also publish the evidence on the website simultaneously. Here, we would like to thank Goose Factory , provided us with all the information.”

   Chat Evidence! Goose factory!

   On the Internet, chatting is already very fashionable. This tool belongs to Goose Factory. Of course Goose Factory can copy all the chat evidence!

  So, the evidence of how this island product Long Live started to complain on the Internet, how to join the chat group, and how to start spreading rumors on the Internet were all revealed.

  The rumormonger standing on the defendant's seat began to tremble. Suddenly, he thought of something: "Long live I am not an island product, I am not, you are slandering!"

   "It seems that we are going to provide a second piece of evidence."

  So, the video of the reporter appeared at that time, and the unruly appearance of the rumor maker appeared on the screen. At the same time, the video also recorded his operation interface. The name is absolutely correct.

   "The names can overlap, but this unique ID number will not change. Moreover, we still have videos of your chats, which will be handed over to the judge for trial."

  The face of the rumormonger completely changed.

   "The evidence submitted by the Mingzhou Group is convincing, the defendant deliberately planned to create trouble, and spread rumors to the Mingzhou Group on the Internet, and the compensation is one million!"

   "Compensation is compensation, and I can't afford it." Long live the island country product is still very calm.

"Wait, we have to submit another piece of evidence. This is a typical case of collusion with foreign forces. The purpose is to spread rumors and even subvert us. The defendant's account has received overseas remittances. We believe that this The remittance is the defendant's illegal income, and the court is requested to confiscate it."

   "No, you can't do this." Long live the island country product was dumbfounded.

   "The evidence is solid, this is illegal income, it will be confiscated!"

   "Defendant Pan Han, if he can't pay the compensation, the sentence needs to be commuted to 10 years in prison!"
