Great warships

Chapter 756
So fast?Qin Tao was a little dumb.

"Of course, 1 years is too long, just seize the day!" Elder Lin said.

He really couldn't wait. After all, the strategic bombing capability has always been the shortcoming of the Air Force. Now the three White Swans can still hold up, but they have been hidden in the dark and cannot show up. If a stealth bomber is developed, If it is publicly displayed to the outside world, it will definitely promote the country's prestige and military prestige.

Elder Lin is full of expectations.

"Then do we have to pass by Factory 172 and Factory 430? We have to see how their research and development are progressing." Qin Tao said.

In fact, he just made a decision on the stealth bomber project. After all, his team can’t be dispersed, and there must be a new project. Twin-engine heavy aircraft can’t be done, so he can only build stealth bombers. Now, everything Without going on with the arrangement, I took Mr. Lin over directly, a little hasty.

But Elder Lin couldn't wait.

"Do you want to know the progress of the imitation of the NK-22 engine of the Tu-32M bomber?" Mr. Lin said: "There is no need to go there, they are here, I will make a call and ask them to come over. Forget it, let's go there, It’s more formal to discuss these in the conference room.”

"Mr. Lin, we just drank several glasses of wine, and now this man is full of alcohol, is it appropriate in the past?" Qin Tao asked.

"What's inappropriate?" Elder Lin shook his head: "These few glasses of wine are meant to moisten your throat, and you're afraid that I'll go crazy?"

After Mr. Lin finished speaking, he took a few more sips and put down the bottle: "Come on, let's go now, the atmosphere is just right."

Qin Tao could only follow.

At this time, the meeting of the Air Force had just ended, and everyone received their tasks and filed out of the meeting room. At this moment, a voice came from the opposite side: "Comrades from Factory 172 and Factory 430 stay, and the rest People can go!"

Leader Liu was still sorting out documents on the rostrum. Hearing this voice, he quickly stood up and strode towards the door: "Old Lin, what's the matter with you?"

"Well, there is something, I want to ask them to understand." After Lin Lao finished speaking, he gave Leader Liu a blank look: "What? I don't have this right now?"

"Of course." Leader Liu nodded quickly: "I will also stay and attend the meeting."

Although Mr. Lin has retired, he is definitely not just a casual person. He still has a lot of energy. If he really dislikes Leader Liu, he can still get him away.

Seeing Mr. Lin and Qin Tao together, Zhou Guozhen became inexplicably excited. He hadn't seen Mr. Qin for a long time. This time he came with Mr. Lin. He must have something important to do. Could it be that he wanted to inquire about Hong Liuk? And H[-]J's progress?

Elder Jiang from Factory 430 had a complicated expression on his face. His throat twitched a few times as he wanted to say something.

"Mr. Jiang, how are you doing recently?" At this moment, Qin Tao passed by Mr. Jiang and greeted him.

"Very bad." Jiang Lao said casually.

"What's wrong?" Qin Tao was taken aback for a moment, the attitude of Mr. Jiang seemed very unusual.

"President Qin, you promised us to develop a 32-megawatt gas turbine on the basis of imitating the NK-[-] turbofan sixteen. As a result, you..."

Mr. Jiang was very excited at the beginning. They surveyed and mapped the imitation NK-32 engine, which was related to the key bomber model of the Navy and Air Force. Moreover, they also proposed to improve the gas turbine on the basis of this engine.

Factory 430 wanted to build gas turbines. It was not a day or two. When they were working on the GT-15000, they went to help, so they had this idea. What happened?Mr. Qin said that we should imitate Spey first, so Factory 430 said goodbye to this kind of gas turbine.

Then, there is NK-32, which is a large turbofan engine. On the basis of this engine, it is enough to develop a gas turbine with [-] megawatts. At that time, Mr. Qin promised well. What happened?
Genghis Khan Aviation and Er Mao cooperated to develop a naval gas turbine based on the D-18T engine!And here, because the imitation work of NK-32 has not yet ended, the development of naval gas turbines has not yet started, and it must not be as fast as Genghis Khan Aviation.

This means that the NK-32 modification of the gas turbine is considered yellow.

It's unethical for Mr. Qin to do this!
Mr. Jiang has always been straight-hearted, and now he told this matter in front of Qin Tao.

Qin Tao was also taken aback for a moment, and then remembered, yes, there is such a thing, how could he forget it?

Both NK-32 and D-18T are three-rotor engines, both of which were developed by the Red Empire a few years before the collapse of the advanced engines. However, these two engines are still different. NK-32 is for bombers. It is still a supersonic bomber, so its bypass ratio cannot be too large, otherwise the windward area will be too large, and the D-18T is used for transport aircraft. In order to save fuel, its bypass ratio is very large.

Therefore, if the two need to be changed, the D-18T is more suitable. Whoever saves fuel will use it. At the beginning, Qin Tao agreed to modify the NK-32 because there was no other choice. Now that the D-18T is available, of course it must be used later. Moreover, by modifying the naval gas turbine, the technology of the D-18T can also be studied, so that if the own side also needs a super giant in the future, it can produce a matching engine at any time.

Qin Tao didn't think there was any problem. He was very happy when he communicated with Ermao, but he seemed to have forgotten NK-32.

What now?
Mr. Jiang came to complain, what should he say?
Sorry, I forgot?

No, in this case, Mr. Jiang has to fight Qin Tao desperately.

"Yes, I promised at the beginning, what's the matter?" Qin Tao decided to ask a rhetorical question.

What's wrong?Needless to say?
"Mr. Qin, you are also developing a 40-megawatt gas turbine. Isn't this the same model as ours?"

"What's wrong with being the same, we can compete." Qin Tao said, "Mr. Jiang, it's almost the 21st century. Isn't competition a normal thing?"

Old Jiang was speechless.

In his intuition, Mr. Jiang thought that the Mingzhou Group's project would surpass his own project, but he seemed to have forgotten that there is a competition mechanism now!
Survival of the fittest through competition is cruel to the opponents who are eliminated, but it is beneficial to the entire industry. After all, only competition can develop.

The 430 factory has been relying on the appropriation from the superior over the years, and the model is also given by the superior. Whether it is Spey or NK-32, it has been a long time, and they seem to have forgotten the competition mechanism. Now, thinking of this, Mr. Jiang's face I am ashamed.

"Yes, competition is competition, we have nothing to fear." Jiang Lao said: "We have confidence in our products."

Elder Lin walked ahead and didn't care about these trivial matters. He knew that Qin Tao would solve them easily.

At this time, Elder Lin and Leader Liu had already walked to the front and sat on the rostrum. Elder Lin looked down and said, "Lao Jiang, let me tell you about your progress in surveying and mapping the imitation of NK-32."

Hearing Elder Lin ask this, Elder Jiang finally cheered up again.

"Okay." Jiang Lao nodded: "With the help of the NK-32 prototype and the original engine designer Sobolev and others, the imitation of the turbofan [-] is progressing very quickly. So far, we have A prototype of the core machine has been manufactured and is ready to start the test run.”

This is NK-32!

In the various materials of later generations, it is said that this kind of engine blows to the sky, and it is said that it is a treasure that the old man pressed the bottom of the box, and he would not sell a single screw to Dongfang.

This is of course nonsense. The old man can't produce it himself, so how can he sell it to Dongfang? However, the technology of this engine does have many unique features.Especially in terms of maximum thrust, it is definitely the strongest engine for bombers in the world.

Without this level of engine, it is impossible to produce a large bomber. The Tu-160 has a maximum take-off weight of 275 tons, relying on this engine.

"When we imitated, we found that Lao Maozi's engine had many backward technologies, so we used our own technology to modify it. Therefore, the performance should be stronger than Lao Maozi's original version, especially the lifespan. We don't expect It is less than [-] hours, and it may reach more than [-] hours after passing the long-term test run in the future."

These are domestic strengths, especially the 430 factory that imitates Spey. Their Spey has a very long lifespan. Coupled with the development of domestic aviation technology, the performance of the imitated products has improved a lot, which is normal. .

At this time, upon hearing the progress, Mr. Lin nodded with satisfaction: "It seems that within three to five years, this engine should mature."

"Yes, we will definitely not delay the production of H[-]K and H[-]J," Jiang Lao said.

Factory 430 and Factory 172 are located in the same city, and they have many connections with each other. Now, relying on the bomber project, the two factories have combined into a close whole.

"It shouldn't be difficult to make changes based on this engine, such as removing the afterburner and turning it into a non-afterburner engine?" Mr. Lin asked.

"It's not difficult...Old Lin, do we have a new project?" Mr. Jiang is very sensitive. One engine corresponds to one aircraft, one radish and one hole. Now Mr. Lin suddenly wants an engine without afterburner, which means What?
There must be a new project.

Leader Liu also cast his expectant eyes over. Mr. Lin has retired, and he would not come here under normal circumstances. He came here suddenly today, and he brought Mr. Qin with him. There must be something important. Could it be that the Mingzhou Group is going to New project, with this non-afterburner engine?

what project is thatMust be some kind of bomber!

Thinking of this, he also became excited.

"Old Zhou, what's the progress of your surveying and mapping of the imitation Tu-22M?" Elder Lin didn't answer directly, but asked Zhou Guozhen again.

"We encountered many difficulties during the imitation, but we overcame them one by one." Zhou Guozhen said: "After all, we have experience in producing the H-[-], and we also have a lot of advanced technologies, such as the launch of the aircraft. Drop frame, in the past, we need to use welding to manufacture, now, as we already have [-] tons of die forging presses in our country, we can already forge as a whole, coupled with our advanced CNC machining center, The quality of the manufactured ones is better than Lao Maozi’s.”

Last time during the development of the Coordinating Transport 7.5, Qin Tao heard Tang Changhong talk about the problem of the landing gear. At that time, he decided that we should do it ourselves. The world's largest is [-] tons, so we will build a Eighty thousand tons came out!

After all, if you want to build a big plane, you can't do without this kind of thing.

Although it cost a lot of money at that time, it was of great benefit to the development of large domestic aircraft. Now, the benefits are reflected: when mapping the imitation Tu-22M, the landing gear of the aircraft can be integrated directly forged.

Even if Lao Maozi's Il-76 was forged separately and then welded together, his own landing gear was finally forged as a whole, so the strength will naturally be higher and the lifespan will be longer.

"There is also the overall beam of the aircraft. We can also use this die forging press to forge the whole body. This process has been used in the [-]th shipment. Our bomber is the same. Many parts are pressed up. The quality It can be much higher, but if we want to say that we are most proud of that wing box.”

Since Mr. Lin has retired and is no longer in charge of these tasks, he doesn't know much about these situations, and Qin Tao is usually busy with work and doesn't pay much attention to them, so that it is now the first time Qin Tao has heard of these things. progress in the field.

All fighters with variable-sweep wings need a wing box. This wing box is like a cover that wraps the rotating shaft inside, so as to avoid exposure and also play an aerodynamic role.

Compared with other aircraft, this additional wing box has become a major contributor to the empty weight of the fuselage. Aircraft designers hope to minimize the weight of this wing box.

The American Tomcat fighter uses a titanium alloy wing box, so that Grumman had to invent a new vacuum electron beam welding technology. In this way, it is said that the weight of the Tomcat's wing box has reached [-] kilograms, while Lao Maozi is relatively rough and uses stainless steel directly.

For a bomber of the Tu-22M class, the wing box must of course be made of stainless steel. The old man is very generous at certain times, such as using titanium alloy to build submarines, and at other times he is very stingy, such as the variable-sweep wing box. Of course, this may not be because the old man doesn't want to use it, but because he can't overcome the welding difficulties.

So, how did you solve it?
Qin Tao became curious: "How did we make that wing box?"

"We used 3D printing technology." Zhou Guozhen said.

Qin Tao knew about this technology, and had helped Anxi make a batch of Tomcat fighter parts, but Qin Tao only thought that this 3D printing was used to make small parts, and something as big as a wing box could also be 3D printed?

"Our 3D printing technology can already print large parts?"

"Yes, parts of up to 12 square meters can be printed." Zhou Guozhen said: "We use titanium alloy as the wing box, which is of good quality and light weight, even lighter than that of Tu-22M."

"We need to be cautious in making changes. We need to solve the problem of availability first. You have reduced the weight. Do you still need to add counterweights?" Elder Lin became serious.

China has been imitating aircraft for a long time, so there is a problem: because the technology of imitating aircraft has not been thoroughly understood, so imitation is possible, but there are many problems in improvement.

For example, during the improvement process of the J-[-], Marconi's avionics were used to reduce the weight, but a cement counterweight had to be added to the nose, otherwise the aircraft would be unbalanced until it was improved into a double triangle The counterweight was only removed when the winged J-[-]E was used.

The improvement of the J-001 has also repeated this process. Although the domestic radar is used, the weight is much lighter than the one-ton N[-], but additional counterweight must be added, otherwise the flight control must be adjusted, but the flight control I didn't understand it!

Now, the imitation of Tu-22M will encounter similar problems if it loses weight rashly.

"If it is in other places, there will be problems if you lose weight rashly, but the part of the wing box should be fine, because this part is at the center of gravity." Zhou Guozhen explained.

Although Mr. Lin is from the Air Force, Mr. Lin is not an aircraft designer after all, so in many respects, he is still not professional enough.

For other aircraft, the center of gravity may be at any position, but for variable-sweep wing aircraft, the center of gravity must be at the center of the line connecting the positions of the two wing boxes. Only in this way can the center of gravity be guaranteed when the wings rotate The position of the center of gravity remains unchanged, otherwise, it would be a disaster for a hydraulically controlled fighter, and it may change from static stability to static instability at any time.

Therefore, if you reduce the weight of other parts, such as the nose or the tail, it will cause the center of gravity to change, which will make it difficult to modify the fighter. However, if you only reduce the weight of the wing box, there will be no problem.

Hearing Zhou Guozhen's introduction, Elder Lin nodded to express his understanding.

"Old Lin, you have asked us so many questions, do you have any new tasks?" Zhou Guozhen asked.

At this time, Elder Jiang was also full of expectations there. When he asked just now, Elder Lin was perfunctory. Now, Zhou Guozhen asked again, what kind of mission is this? Will Old Lin say it?
"Everyone has been engaged in the military industry for half a lifetime, have you forgotten the discipline of secrecy?" Elder Lin said, "Don't ask if you shouldn't ask."

So, no one asked.

Mr. Lin stood up: "Okay, let's stop here. By the way, shouldn't it be time to eat? Hurry up and eat."

Seeing everyone walking out, Leader Liu said, "Old Lin, is it the next-generation bomber project?"

Others can't ask, but Leader Liu has to know, after all, he has the final say in the Air Force now.

"Yes, President Qin and I discussed it just now." Elder Lin nodded: "Mingzhou Group will develop this stealth strategic bomber, which can fly to the opposite side of the Pacific Ocean and then return."

Leader Liu took a breath: "Mingzhou Group's next development project?"

"Yes." Qin Tao nodded: "After the vertical take-off and landing J-31A is completed, we will officially start this project."

"How much money does the air force need to invest?" Leader Liu's words trembled because of excitement.

"I've thought of two ways." Qin Tao said: "The first one is that the R&D funds are completely raised by our Mingzhou Group, but after the R&D is completed, the price is up to us. When the time comes, we will sell it to the Air Force. The price must be to share the research and development funds, if the Air Force purchases a small quantity, perhaps one aircraft will cost one billion."

The cost of the B-2 bomber is more than 6 million U.S. dollars, but if the research and development funds are allocated, it will become more than 20 billion U.S. dollars. Domestic research and development has a cost advantage, but even so, it is very expensive to develop, one billion A bomber is definitely not much, and it will even be higher in the future.

However, no matter how much the final purchase price is, this arrangement can at least save the Air Force from spending money now. After all, for the Air Force, the current funds are still very scarce. They have a large number of procurement plans, J-35, J-[-], J-[-] Sixteen, J-[-], etc. Spending money in the future is a matter of the future. Now it is fine to not spend money. In the future, the country's economic strength will be stronger, so it doesn't matter if you spend more money.

As for not wanting the Air Force in the future, let Mingzhou Group's huge investment be in vain?This is absolutely impossible, this kind of big killer is the dream of the Air Force, why would they not want it?If they don't want it, then Mingzhou Group can sell it. Apart from the United States, no other country has this kind of killer, so there will definitely be users.If others don't say it, the big dog will definitely want it.

"Another way is for the Air Force to fully intervene. From the beginning of development, the Air Force will invest. In this way, the future purchase price will be the production cost plus profit." Qin Tao continued: "If the Air Force is willing to invest, then the entire development process , the Air Force can participate, and all kinds of new ideas can be raised at any time.”

"Boss Qin, is there a third option?"

Qin Tao became curious: "Leader Liu, tell me what is the third type?"

"Our air force provides part of the funds, but we also hope to get involved and follow up every process of the development at any time." Leader Liu said.

Qin Tao nodded: "Deal!"

This is the most urgently needed strategic bomber for the Air Force. Of course, the Air Force cannot stay out of the matter. They must join in and take the lead!In this way, they have to contribute money, but it is somewhat unaffordable to pay all the money, so they hope to only pay part of it.

Seeing Qin Tao nodding, Leader Liu continued: "If nothing else happens, the engine used on this bomber should be the Turbofan [-] that we surveyed and imitated, right?"

"Yes."

"The Air Force has invested a lot of money in this program, can we count that as our funding for this stealth bomber?"

"Of course not." Qin Tao refused directly: "Leader Liu, you are too shrewd in your calculations. The funds you provide us must be credited to our account."

Leader Liu smiled: "Okay, let's think of a way in the Air Force. If there are too many, I dare not say, and we can still scrape together a few million."

In the outside world, a few million is an astronomical figure, but in the air force, a few million is just a drizzle, which is only enough for an air force base.

"The start-up capital of a few million is enough." Qin Tao nodded: "In the future, when the Air Force has money, don't forget about us. By the way, Leader Liu, does the Air Force need to send someone to keep an eye on this project?"

Leader Liu nodded: "Of course."

"Then, please ask Mr. Lin to stay in our Mingzhou Group in the future?"
