Chapter 232 Submarine-launched anti-ship missile
In the era of submarines, the main weapon they used was torpedoes, which were underwater weapons to attack the enemy.However, torpedoes also have many disadvantages.

For example, the speed is slow. Even if the speed of the torpedo reaches [-] to [-] knots, it is too slow compared to the missile. During the attack, the target will perform various maneuvers, so the success rate is not high.

However, a submarine navigates underwater after all, and its weapons have nothing but torpedoes.

It was not until the emergence of nuclear submarines that there were ballistic missile nuclear submarines, which were specially used to launch ballistic missiles and became the most important force for the second nuclear counterattack.

As for nuclear submarines launching anti-ship missiles, there are also some, that is Oscar, this kind of submarine exists to destroy the enemy's surface formation.

However, their anti-ship missiles are specially made, with a range of hundreds of kilometers, and they are designed to hit aircraft carriers. What does our side have?The one that can be obtained is Haiying No. [-]!
"We have also tried the anti-ship missiles launched by submarines. It is the 033G submarine. However, after the test, it is outdated, so it has not been used in large quantities." Zhang Lao said.

Adding anti-ship missiles to submarines is also something that naval technicians can think of. Therefore, after the success of Haiying 033, the navy also transformed an old-fashioned 6 submarine. There are [-] anti-ship missile launchers installed at the front and back, forming a significant bulge.

When submerged in normal times, these launching devices are flat, and when it is necessary to launch missiles, the launching tubes are erected, and the vertical is about [-] degrees.

In order to meet the needs of launching missiles, the submarine was also equipped with a 358G sea search radar, a 925G radar reconnaissance aircraft, an automatic wind detector, an azimuth level instrument, and a digital shooting director for mine bombs, etc. equipment.

However, it is still a surface launch method, just like the path traveled by the first flying missile submarines of the United States and the Soviet Union.It was quite nonsense to expose a submarine that was supposed to be hiding in the water to the sea [-] kilometers away from the enemy fleet.

Therefore, before the experimental mission was completed, the experimental submarine was abandoned and never used again.

"Now, we are studying the way of using torpedo tubes to launch anti-ship missiles, and we have achieved some results." Zhang Lao continued.

What kind of secrets are those, after all, it is something to retreat first.

Maozi nodded: "If it is a conventional submarine, the space is unlimited, so, you can use that method, but for your nuclear submarine, it is not a bit outdated. You mean, at the proper position on the bow of the submarine, Arrange some vertical launching devices to launch anti-ship missiles directly on the water when needed. That method is the lowest in efficiency. Moreover, you have already overcome the difficulty of launching ballistic missiles on water, and you can transplant related technologies. .”

What Fei Yi wanted was to launch vertically!
The torpedo tube launch can use the existing weapon system, which is very convenient, but the effect is good. In that way, the missile needs to be wrapped in a submarine carrier like a torpedo, and it is small from the outside of the torpedo tube. The carrier rushes out of the water and then ignites the missile to launch. This is called the "dry launch method", and the speed is also very fast, which is incomparable with the effect of direct vertical launch.

There are not many difficulties in launching missiles on the water. After a long time of domestic research, we finally overcome each technical problem. Now the 092 nuclear submarine can retreat and be on duty. Therefore, there are some minor problems in transplanting the technology.

"He said that during the development of your new generation of nuclear submarines, you will use submarine-launched anti-ship missiles as a fixed piece of equipment?" Mr. Zhang finally understood what Maozi meant.

"It's wrong, that's it. In the past, your nuclear submarines used torpedoes much more often than anti-ship missiles. If it's not possible, the size of the launch tube can be smaller, for example, 850mm. Wait until before, Your domestic cruise missile technology has made breakthroughs, and you can carry cruise missiles, as well as other small-power weapons."

In the past, torpedoes were used to hide and seek with submarines of other countries, while anti-ship missiles were used to attack surface targets. Those are two different combat methods.

Although there is no such little guy as the P-700, the performance of Cao Lao No. [-] is already very wrong, and before that, in the case of changing the shape and size, as long as a new engine is installed, the range can be improved. Break through a hundred kilometers.

Therefore, when designing 093 nuclear submarines, it is very unnecessary to use submarine-launched anti-ship missiles as an indicator.

Without that thing, it is only anti-ship missiles, and other missiles can also be launched, such as cruise missiles for ground attack, supersonic anti-ship missiles that retreat first, or even anti-ship ballistic missiles. In short, as long as it is impossible, Keep it as small as possible.After all, it is difficult for nuclear submarines to change their launch tubes.

These small weapons can also be fired through 533 mm caliber torpedo tubes.

Mr. Zhang nodded: "You will seriously consider the plan he proposed."

"There is no place for the towed body sonar yet. The submarine of the Old Sea Eagle has already finished placing it under the tail. If you think that plan is wrong, you can also consider it. Put it in front of the conning tower and make a turtle back out. Beautiful."

The turtle back in front of the 093 conning tower is criticized by few people. It is obviously attacking a nuclear submarine. It has to suffer from the hunchback problem of a ballistic missile nuclear submarine. What is it that is stuffed outside?Towed body sonar?Is it possible to change places?
Look at the design of the old Seahawks, it's all wrong.

Listening to Maozi's eloquent explanation outside, Mr. Zhang suddenly had an illusion: "What do you think, it would be better if he came to design nuclear submarines?"

"You just saw very little outside of Old Haiying, so you came back to show off." Fei Yi hurriedly humbled.

"Yeah, I have seen a lot and know a lot. If you know that there is no such opportunity, you should also go there, the Oscar nuclear submarine of the old sea eagle!" Zhang Laowu felt a little emotional.

Speaking of surface ships, the Old Seahawk is more powerful than the Americans, but when it comes to water power, the Old Seahawk is definitely weak enough. The Oscar nuclear submarine is one of the masterpieces. A small shark with tens of thousands of tons, what should it look like inside? scene?
Mr. Zhang wanted to see it very much.

"Do you want to see it? Last time you found a chance to take you to see it. It's a big deal." Maozi said very modestly. Outside of me, it seemed to be a trivial matter.

After some introductions and arrangements, Fei Yi tossed until midnight.I also rushed over before I heard about the incident over there. Zhao Ling was still taking Vitalia to play in the capital, doing her best as a landlord.

Everyone's energy is good, Maozi can bear it, before returning to the office, he opened a folding bed and took a nap.

On the seventh day, early in the morning, I was woken up again, and the work of the day was over again at each station.

Wu Shengli only rested for half the night, and went to watch the construction of 051C before dawn.

Since time has passed for a long time, the 051C at this time is only the first segment of a bow, which can be seen as the outline of a warship. However, the aircraft carrier under the berth, The construction regression is much slower, and the second half of the hull is slowly completed, which is really enviable.

Maozi rubbed his eyes and came to the berth. Beside me, followed by a small group of people, were reporting to me the work during that time.

"This natural gas ship has been put into operation abnormally. The owner's response is very good. My colleagues have also seen your construction quality. It is estimated that it will take a long time before there will be no new orders."

"The inner shell of the catamaran yacht has been built, and it is undergoing interior decoration. Would you like to go and see it?"

"The gantry crane has been erected, and the dock is preparing to start construction. However, the geological survey is too optimistic, and it is impossible to affect the progress of the construction."

It was so difficult to see Mao Zi come back, the little guys surrounded me, kept talking about some recent things, Mao Zi also responded casually, and gave a solution.

Just like that, all the way down the berth, Maozi saw Fei Yixing and the others, and showed a wry smile.

"Oh, it's just a bunch of things when I come back."

"The lower the position, the smaller the ability, the smaller the responsibility, and the fewer things to do." Wu Shengli said: "That is also a test for you."

"Hey, you just want to build a ship safely outside the shipyard, but you want to deal with so few things." Maozi said: "Oh, when Xiaojia can take care of himself, you will be fine, by the way, titanium alloy Relevant experts, are you here?"

While talking, Maozi's little brother rang.

"President Qin, President Qin, you just received a titanium alloy expert from the capital!"

"Well, please let me go to the conference room." Mao Zi was very satisfied. The topic that was brought up yesterday, the expert came over today.

After inspecting the shipyard and returning to the conference room, the Santana car that picked up the expert also drove back to the shipyard.

office.

Maozi looked at the person who appeared in front of him, and he respected him very much: "Qin Tao, did you ever think that we would invite you here!"

"Leader Wu said hello, can you come? It's just that you came late, did you come with me?" Qin Tao said with a smile.

Qin Tao, who was born in 1934, is the founder and pioneer of the domestic titanium alloy field. I accepted the task assigned by the state at the age of 22 and finished researching titanium alloys. At that time, I still knew about titanium alloys. Now, I have become In addition to being an authority in that area, I am also the chief scientist of the "863" program in China.

When I heard that there was no more than a thousand tons of titanium alloy, I was immediately moved and rushed to Mingzhou overnight.

Now, a group of people sat under the chairs in the meeting room and ended the exchange in a friendly atmosphere.

"Old Cao is an authority on titanium alloys in our country. You remember that in 56, Lao Cao participated in the preparation of the first aviation titanium alloy laboratory in China. In a blink of an eye, decades have passed." Wu Shengli Said with emotion.

"Yes, you have spent your whole life researching titanium alloys. In our country, titanium alloys can only be used in the aviation industry. The old sea eagle is really luxurious. It directly uses titanium alloys for the interior of submarines. Shell." Qin Tao said: "Now, you just want to take a look."

Fei Yi hurriedly waved his hand: "Qin Tao, you can see what you see now. The equipment outside is still being dismantled, and the inside shell is still covered with sound-absorbing tiles. We have to wait for a while. Yes, some preparations We have to pay attention to the work, for example, what tool should we use to cut the shell?"

If it were a submarine with a special steel inner shell, we would have been able to use gas cutting to dismantle the submarine into four pieces.

However, titanium alloys are OK.

That thing is very common, direct exposure to oxyacetylene flames may cause changes in the internal composition of the titanium alloy, such as hydrogen embrittlement, Mao Zi is a material professional, and can only know a little about it.

Professional things have to be done by professional people.

"Mr. Qin, it seems that you still have no research on titanium alloys." Qin Tao said with a smile: "You know that you can use flames to cut, very good. In order to destroy the properties of titanium alloys, you'd better use heat to cut them. cut like a saw."

"Hot saw? That's such a small project!" Maozi couldn't help but sigh with emotion.

The oxyacetylene flame is the slowest, and the cutting saw is much faster. If it is a hot saw, this is simply a snail's speed!
Titanium alloy material is one of the most difficult types of metal alloy materials. For titanium alloy cutting, a hot saw is especially used. It uses a special wear-resistant cermet cutter head, and then cuts quickly.

If the speed is slow, there will be less friction and cold. Once the cooling exceeds a certain value, the performance of the titanium alloy will change.

When cutting steel, you can see sparks flying, but when cutting titanium alloy, you can definitely see sparks, otherwise the material will be scrapped.

A submarine contains [-] tons of titanium alloy, so if it is cut quickly, how long will it take?

Maozi lost the urge to vomit blood.

"Yes, so, you suggest cutting a large piece first, and you study its composition. If it can meet your needs, you can directly cut it into the desired shape and process it into a finished product on site." Fei Yi put forward his own opinion .

虽然都是钛合金，但是区别还是很小的，什么TC4、TA15、TA7、TA5、Ti-75、TA12、TA18、TA19等一小堆的规格，得先知道那种钛合金具体是什么成分。

"Well, your plan is feasible. You can buy the equipment you need, and your technical service fee will definitely be high." Fei Yi said: "It is a second-hand product after all. If you can process it into the parts you need, you can charge for it." A [-]% discount on abnormal products."

Disassemble and sell titanium alloy directly, tens of thousands of dollars per ton, which is wasteful, so Maozi intends to make industrial parts, but I am unfamiliar with those, and now, experts have come and proposed the best solution, Of course I refused, the money and everything were in place, and I asked those people to stay and help.As for the product, it is brand new after all, and the profit at [-]% off is quite astonishing.

"[-]% off? Do you think few departments will thank Mingzhou Shipbuilding Industry Group." Qin Tao said to Maozi: "Especially our fighter manufacturing requires less and less titanium alloys."

For the J-27 currently being produced in China, the amount of titanium alloy is only 17.00%. When the J-[-] is reached, it will be increased to [-]%. When the localized Su-[-] is the J-[-], the amount will be reduced to [-]%. .

The proportion of titanium alloy used is getting lower and lower, and the price of aircraft is getting more and more expensive. If Maozi can provide a batch of high-quality and cheap titanium alloy parts, it can still effectively reduce the cost, even if it is [-]%. It can also save a lot of money.

"Teacher, if you use those seven-handed titanium alloys to build parts, will it cause stress?" At that time, a student brought by Fei Yi asked.

Any metal is free of stress problems, the stress is quickly released during long use, and now, rebuilding parts with those seven-handed titanium alloys will continue to encounter that problem.

"If you want to avoid that problem, you have no idea." Fei Yi looked at the student and said, "Have they heard of 3D printing technology?"

If the cerebellum hurts, go to the hospital to take a CT scan, and you will get pictures one by one, which is equivalent to cutting the cerebellum into few layers, and then taking pictures of the previous layers. If you stack them all together, you can reconstruct a whole cerebellum.

The same is true of 3D printing technology. It prints a three-dimensional pattern, but it is realized by printing layer by layer. Raw materials such as metal powder or wire are melted, arranged according to the requirements of the computer, and then solidified, one layer after another. Layers are constantly melting and solidifying, and are constantly accumulating to become a three-dimensional part.

What's the use of doing that?
Because the metal is solidified before melting, the stress is automatically eliminated. At the same time, it can print simple parts. If it is to be forged with an open die, the cost will be quite low. At the same time, it can perfectly print the same metal blend together.

In 1986, American scientist Charles Hull developed the first commercial 3D printing machine, yes, it printed metal materials.

At this time, when Fei Yi mentioned the technology, the student nodded solemnly: "Of course I have heard of it, but this is only used to print non-metallic materials. Could it be that your titanium alloy can also use 3D printing technology?"

Fei Yi nodded: "Now, that technology is blank for the time being, which also gives you a chance. If you can overcome that difficulty, you were able to manufacture a variety of titanium alloy parts in small quantities before this. This kind of welding problem, you need any simple shape parts, just input the printer, you can make it! That will be your technology for overtaking on curves!"

Fei Yi said it without a sound, because I know that the domestic research in that field of technology is very advanced, and the Americans ended the research in 85. However, because the slow solidification of metals and other technologies are fixed, It is necessary to give up, but the country has persisted for more than ten years, and finally succeeded. In 2005, the J-3 used the first parts produced by [-]D printing technology. Before that, various parts emerged one after another. If you are poor, you can print whatever you need, even small aircraft components.

Compared with open die casting, it saves a small amount of cost and improves efficiency. Moreover, it can be applied to other aspects, and eventually becomes a technology that is needed by a small number of people.

"You have heard of that technology, but it is too difficult to study." The student continued: "You need to melt the consumables slowly, that requires a laser beam or a low-power electron beam, and then slowly Rapid solidification, layer upon layer. Now, do you have any theoretical basis."

The back of Maozi's eyes lit up, and the other party said those things in a clear and logical way, which means that I know!

"There is a mistake. It is not easy to do scientific research." Mao Zi said: "Your Mingzhou Shipbuilding Industry Group plans to establish a new research institute to specialize in the application of titanium alloys. Qin Tao, do you think you want to try it? ?”

Fei Yi sighed: "Mr. Qin, we all say that he has no vision. All the hearing is true. His knowledge is quite wrong. The technology of 3D printing has no future, but the money to be invested is also very low. Not much. Does he want to fund your research in that area now?"

"Yes, you contribute funds, they contribute technology, and jointly conduct research. Each will get half of the shares. Before success, the profits will be divided equally. How about it?" Fei Yi said.

Our Mingzhou Shipbuilding Industry Group has developed very wrongly now, and we can spare part of the funds to do research, 3D printing of titanium alloys, and such low-level projects. If there is no chance, Maozi will certainly want to start.

"If it is successful, it will be equivalent to a revolution in materials science and metallurgy. It can have a small impact on your manufacturing industry, and your military equipment can also benefit from it." Fei Yi continued to fool around.

I have no money, but I have the technology. I can do warships, but I can only place my hopes on others when it comes to materials.

The Qin Tao in front of me is a teenager who is studying outside the field of titanium alloys. Those people in my hands are also elites. If those talents can help me, it will be the best.

Qin Tao looked at his student: "My lord, does he have any ideas?"

"Teacher, in fact, you have already discovered the advanced nature of 3D printing technology, but there is no way to get involved. Now, without that opportunity, you want to give it a try." The student said: "In your life, Wang Hua, As long as one thing is done, nothing is accomplished.”

Wang Hua?

Mao Zi was surprised for a while, what is that called?
If you break through the iron shoes, you can find a place, and it takes a lot of work!

Wang Hua in front of him is still Qin Tao's apprentice, so there is nothing wrong with that. That person must be the inventor of 3D printing technology in China!Funding me to do that project myself, the success rate is [-]%!

"Well, since he wants to do it, let's do it. Yes, you don't have a suggestion." Qin Tao looked at Mao Zi: "They don't have a research and development atmosphere outside, and they can put that research and development organization in elementary schools. If you go outside, you can hang their brand of Mingzhou Shipbuilding Industry Group, and then each holds half of the shares."

Fei Yi originally planned to do it in Mingzhou, but it is a small city after all, and outstanding talents hate staying in a small city, so I thought about it for a while and then nodded.

"It can be set up in Huating or the capital."
