Great warships

Chapter 657 [-]-ton Die Forging Press
"Mr. Tang, you 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.

Such a large aircraft 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-[-]. 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 the information back. There is nothing in this world that 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 similar to that of 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 those of the Il-76. We designed a maximum take-off weight of 220 tons, the length of the cargo box was 20 meters, and the width and height were increased to four meters."

伊尔76的横向界面剂更小，是3.46米×3.4米，别看眼前的运20货舱的宽度和高度只比伊尔76增加了0.56米和0.6米，这对空间局促的运输机来说意义重大。里面能塞进去的货物会更多。

"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 smiled and shook her head, of course not, since then, she has been by her husband's side, there are deficiencies in various aspects in the country, her strength alone is small, but by her husband's side, she can play a greater role.

Husband is a capable person!
If she had realized this earlier, she would have followed Qin Tao a long time 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-[-] also plans to modify this engine, we A large number can be imported, but if we don’t want to be controlled by others in the future, we have to survey and map the imitation of this engine. At present, we have already started the preparation work, and we can use our own engine after the imitation comes out.”

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

However, the imitation is only for emergencies, and domestic research is still necessary. The self-developed product is Turbofan-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 saves 30.00% fuel consumption compared with the original engine, which increases its range from the original 7800 kilometers to 10000 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 surveying and mapping 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.

"You used 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 with 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. "

Over the past few years, domestic avionics technology has developed rapidly. These things have appeared on fighter jets, and now they have been transplanted to transport aircraft!
"This seat is really comfortable." Wu Shengli was already lying on the back seat: "Who uses this chair?"

In general large aircraft, there are two seats in the 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 foldable 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 resting 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 behind the three of them. 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, two people are enough?

"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 there is an accident, fewer people will be sacrificed. By the way, after the modification of our H[-], the pilots needed Is it less?"

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

The advanced cockpit in the front made 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.

"Mr. Qin, of course we remember our original promise, 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 degree, and then put it inside for beating.

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

All over the world, the [-]-ton hydraulic press is already very strong.However, in the field of die forging presses, the [-]-ton class is far from enough.

"In the field of die forging presses, 4.5 tons is a dividing line. At present, the largest in the United States is 6.5 tons, and France is 7.5 tons. Lao Maozi is the most powerful, and their die forging presses are 380 tons. "Tang Changhong continued: "Because Lao Maozi's die forging press is the most powerful, the most advanced Airbus A[-] 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 base aircraft.

"Back then our Yunshi was also a big plane. Without such 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.”

There is indeed experience in China. The landing gear of the H-250 is welded, and there are several parts that are not easy to weld. One is commonly known as the toilet and the other is commonly known as the underpants.Need to use electrode arc welding, preheat [-] 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 American die forging presses are not as good as the French?" Qin Tao asked, he really didn't know about this aspect, after all, they are not used in shipbuilding.

"Because the die forging presses in France are also sold from Er Mao, which is the same factory that produces die forging presses for Da Mao." 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 7.5-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 they are also very large in size: the total height is 34.7 meters, the length is 13.6 meters, and the width is 13.3 meters. The foundation is 21.9 meters deep underground, and the total weight is 20500 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 French?In 1953, Aesop and Crcout-Loire of France built two 2-ton hydraulic die forging presses for the manufacture of aviation aluminum alloy forgings.These were made by themselves. In 76, the French Oberduwaite Steel Company purchased a 6.5-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 4.5-ton machine was built in 55 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 consider profits.

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

Only Qin Tao is the most suitable for this kind of thing. 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.”

"What should I 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 7.5. tons? Then we will build an [-]-ton one ourselves!"

Qin Tao didn't understand the others, but he remembered that in the world before he came, there was the world's most advanced [-]-ton die forging press in China, 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 first-heavy machine or a second-heavy machine, they all 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 people who designed this kind of machine back then, isn't that all right?" Qin Tao said.

Production is not dared to be put in Ermao's place, 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 persons in charge of various projects. Everyone was more relaxed at the wine table, and all kinds of lofty ideals were talked about.

"Within ten years, our transport 21 will definitely become our important air transport force! Our strategic transport capacity can be greatly supplemented!"

"This is not necessarily the case. Our ground-effect aircraft may be mature, and you may be eliminated if you ship [-]!"

"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 grabbing your business!"

Zhao Ling and Qin Tao had dinner with other people before, and now, returning to such an 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.

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

Mr. Qin needs such a good wife.

The next day, Qin Tao looked at his wife curiously: "Aren't you going to Ermao's 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 tell you 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 the innocence of our Mingzhou Group!" Zhao Ling looked very capable in her professional attire.

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

the other side.

The mentally and physically exhausted rumor-monger also came 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 Daoguo went 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!

Thus, 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, and suddenly, he thought of something: "Long live I am not an island product, I am not, you are slandering me!"

"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-monger appeared on the screen. At the same time, the video also recorded his operation interface. That name is absolutely unmistakable.

"The names can overlap, but the unique ID number will not change. Moreover, we still have the video 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 conclusive. The defendant has deliberately planned to create troubles and spread rumors to the Mingzhou Group on the Internet. The compensation is 100 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 that." Wansui Daoguo 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 [-] years in prison!"
