Chapter 233 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 However, after the test, it is outdated, so it has not been used in large quantities."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, these launching devices are flat. When it is time to launch missiles, the launching tubes are erected and tilted at about fifteen 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, 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 hidden underwater in a sea area [-] kilometers away from the enemy fleet.

Therefore, after completing the experimental mission, this 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.

These are not secrets, after all, they are not advanced things.

Qin Tao nodded: "If it is a conventional submarine with limited space, then this method can be used, but for our nuclear submarine, this is a bit outdated. I mean, in a suitable position on the bow of the submarine, Arrange some vertical launching devices, which can directly launch anti-ship missiles underwater when needed. This method is the most efficient. Moreover, we have overcome the difficulty of launching ballistic missiles underwater. OK."

What Qin Tao wants is to launch vertically!
The torpedo tube launch can use the existing weapon system, which is very convenient, but the effect is not good. In this way, the missile needs to be wrapped in a torpedo-like submarine carrier, and it will go out from the torpedo tube. After the vehicle breaks out of the water, the missile is ignited and launched. This is called the "dry launch method", and the speed is also very slow, which is incomparable with the effect of direct vertical launch.

There are many difficulties in launching missiles underwater. After a long time of domestic research, we finally overcome each technical problem. Now the 092 nuclear submarine is ready for combat readiness. Therefore, it is not a big problem to transplant the technology.

"You mean, in the development process of our new generation of nuclear submarines, we will use submarine-launched anti-ship missiles as a fixed piece of equipment?" Mr. Zhang finally understood what Qin Tao meant.

"That's right, that's it. In the future, our nuclear submarines will use torpedoes much less than anti-ship missiles. If possible, the size of the launch tube can be larger, for example, 850mm. In this way, in the future, Our domestic cruise missile technology has made breakthroughs, and it can carry cruise missiles, as well as other powerful weapons."

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

Although there is no big guy like the P-700, the performance of the Haiying [-] is already very good, and in the future, without changing the external dimensions, as long as it is replaced with a new engine, the range can exceed [-]. kilometer.

Therefore, when designing the 093 nuclear submarine, it is very necessary to take the submarine-launched anti-ship missile as an indicator.

With this thing, not only anti-ship missiles, other missiles can also be launched, such as cruise missiles for ground attack, advanced supersonic anti-ship missiles and even anti-ship ballistic missiles. Make it bigger.After all, it is not easy for nuclear submarines to change their launch tubes.

Those large weapons cannot be fired through the 533 mm caliber torpedo tube.

Mr. Zhang nodded: "We will seriously consider the plan you proposed."

"There is also the position of the towed body sonar. Lao Maozi's submarine has already begun to be arranged above the tail. I think this plan is good. We can also consider it. Putting it behind the conning tower and making a turtle back out is too unsightly. .”

The turtle back behind the 093 command tower has been criticized by many people. It is obviously attacking a nuclear submarine. It has to suffer from the hunchback problem of a ballistic missile nuclear submarine. What is stuffed inside?Towed body sonar?Can't we change the place?

Look at Lao Maozi's design, it's really good.

Listening to Qin Tao's eloquent explanation here, Mr. Zhang suddenly had an illusion: "Why do I feel that it would be better if you came to design nuclear submarines?"

"I just learned a lot from Lao Maozi, so I came back to show off." Qin Tao hastened to be humble.

"Yes, I have seen a lot. If I know there is such an opportunity, then I should also go there, old Maozi's Oscar nuclear submarine!" Zhang Lao felt a little emotional.

Speaking of surface ships, Lao Maozi is no match for the Americans, but when it comes to underwater power, Lao Maozi is definitely strong enough. The Oscar nuclear submarine is one of the masterpieces. What is the interior of a tens of thousands of tons of sharks?
Mr. Zhang wanted to see it very much.

"Would you like to see it? I'll take you to see it next time. It's a small thing." Qin Tao said generously. For him, it doesn't seem to be a big deal.

After some introductions and arrangements by Qin Tao, he tossed until midnight.He also rushed over after hearing about the things here, and Zhao Ling was still taking Vitalia to play in the capital, doing the landlord's favor.

Everyone was in good spirits, but Qin Tao couldn't take it anymore. After returning to the office, he opened a folding bed and fell asleep.

The next day, early in the morning, he was woken up again, and the work of the day started again at each station.

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

Since the time has not passed very long, the 051C at this time only built the first section of a ship's bow, and the outline of the battleship cannot be seen at all. However, the construction progress of the aircraft carrier on the berth. It's much faster, the front half of the hull is almost completed, and it looks really enviable.

Qin Tao rubbed his eyes and came to the berth. There was a large group of people beside him, all reporting to him the work during this period.

"The natural gas ship has been put into operation normally, and the owner's response is very good. Other colleagues have also seen our construction quality. It is estimated that there will be new orders in a short time."

"The outer shell of the catamaran yacht has been built, and the interior decoration is underway. Would you like to go and have a look?"

"The gantry crane has been erected, and the dock is preparing to start construction. However, the geological survey is not optimistic, which may affect the construction progress."

It was so easy to see Qin Tao come back, everyone surrounded him and kept talking about some recent things, Qin Tao also responded casually and gave a solution.

In this way, on the way to the berth, Qin Tao saw Wu Shengli and others, and showed a wry smile.

"Oh, there are a lot of things when I come back."

"The higher the position, the greater the ability, the greater the responsibility, and the more things to do." Wu Shengli said: "This is also a test for you."

"Hey, I just want to build a ship safely and securely in the shipyard, but I don't want to deal with so many things." Qin Tao said: "Hey, I will relax when everyone can take care of themselves. By the way, the titanium alloy Relevant experts, are you here?"

While talking, Qin Tao's big brother rang.

"Mr. Qin, Mr. Qin, we just received a titanium alloy expert from the capital!"

"Well, invite him to the conference room." Qin Tao was very satisfied. The topic that was brought up yesterday, the expert came over today.

After inspecting the shipyard and returning to the meeting room, the Santana car that picked up the experts also drove into the shipyard.

office.

Qin Tao looked at the people who appeared in front of him with great respect: "Old Cao, I really didn't expect that they invited you here!"

"Leader Wu said hello, can I not come? It's just that I came late and didn't come with other people." Cao Lao said with a smile.

Cao Lao, born in 1934, is the founder and pioneer of the domestic titanium alloy field. He accepted the task assigned by the state at the age of 22 and began to study titanium alloys. At that time, he knew nothing about titanium alloys. Now, he has become In addition to his authority in this area, he is also the chief scientist of the "863" program in China.

Hearing that there are thousands of tons of titanium alloy here, he was immediately moved and rushed to Mingzhou overnight.

Now, a group of people sat on the chairs in the conference room and started communicating in a friendly atmosphere.

"Old Cao is an authority on titanium alloys in our country. I 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.

"Yeah, I have spent my whole life researching titanium alloys. In our country, titanium alloys can only be used in the aviation industry. The old man is really extravagant. He directly uses titanium alloys as the shell of the submarine. "Cao Lao said: "Now, I can't wait to take a look."

Qin Tao quickly waved his hands: "Old Cao, you can't see anything now. The equipment inside is still being disassembled, and the outer shell is still covered with sound-absorbing tiles. We have to wait for a while. However, some preparatory work We have to start, for example, to cut this shell, what tool do we use most suitable?"

If it were an ordinary steel-hulled submarine, they would have used gas cutting to dismantle the submarine.

However, titanium alloys cannot.

This thing is very special. It is estimated that the internal composition of the titanium alloy will change when it is directly exposed to the oxyacetylene flame. Qin Tao is not a material professional, so he can only know the general situation.

Professional things have to be done by professional people.

"Mr. Qin, it seems that you still have research on titanium alloys." Mr. Cao said with a smile: "You know you can't use flames to cut, that's good. In order not to damage the performance of titanium alloys, we'd better use a cold saw way to cut."

"Cold saw? This is a huge project!" Qin Tao couldn't help but sigh with emotion.

The oxyacetylene flame is the fastest, and the cutting saw is much slower. If it is a cold saw, it is simply a snail crawling speed!
Titanium alloy material is one of the most difficult types of metal alloy materials. For titanium alloy cutting, a cold saw is generally used. It uses a special wear-resistant cermet cutter head, and then cuts slowly.

If the speed is fast, the friction will generate more heat. Once the heat exceeds a certain value, the performance of the titanium alloy will change.

When cutting steel, you can see the scene of sparks flying, but when cutting titanium alloy, you must not see sparks, otherwise the material will be scrapped.

A submarine has [-] tons of titanium alloy. If it is slowly cut, how long will it take?

Qin Tao had the urge to vomit blood.

"Yes, so, I suggest cutting a small piece first. Let's study its composition. If it can meet our needs, we can directly cut it into the required shape and process it into a finished product on site." Cao Lao put forward his own opinion.

虽然都是钛合金，但是区别还是很大的，什么TC4、TA15、TA7、TA5、Ti-75、TA12、TA18、TA19等一大堆的规格，得先知道这种钛合金具体是什么成分。

"Well, your plan is feasible. We will buy the equipment we need, and the technical service fee for everyone will definitely not be low." Qin Tao said: "After all, this is second-hand goods. If it can be processed into the required parts, we can charge normal [-]% off the product."

It would be a waste to disassemble and sell titanium alloys for tens of thousands of dollars per ton, so Qin Tao planned to make them into industrial parts, but he was not familiar with them. Now, the experts came and proposed the best solution. Of course he agreed, the money was given and everything was in place, and these people were asked to stay and help.As for the product, it is not brand new after all, and the profit at [-]% off is quite astonishing.

"[-]% off? I think many departments will thank Mingzhou Shipbuilding Industry Group." Cao Lao said to Qin Tao: "Especially our fighter manufacturing requires more and more titanium alloys."

In the J-27 currently being produced in China, the amount of titanium alloy is only 15.00%. When the J-[-] is reached, it will be increased to [-]%. When the localized Su-[-] is the J-[-], the amount will be increased to [-]%.

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

"Teacher, if we use these second-hand titanium alloys to make parts, will it cause stress problems?" At this moment, a student brought by Mr. Cao asked.

Any metal has a stress problem, and the stress is slowly released over a long period of use. Now, rebuilding parts with these second-hand titanium alloys will continue to encounter this problem.

"To avoid this problem, I have an idea." Qin Tao looked at the student and said, "Have you heard of 3D printing technology?"

If the brain hurts, go to the hospital to take a CT scan, and you will get pictures one by one. This is equivalent to cutting the brain into many layers, and then taking pictures layer by layer. If you stack them together, you can reconstruct a brain.

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. , constantly melting and solidifying, and constantly accumulating, it can become a three-dimensional part.

What are the benefits of doing this?
Because the metal is melted and then solidified, the stress is automatically eliminated. At the same time, it can print complex parts. If you want to open the die forging, the cost will be quite high. At the same time, different metals can be perfectly fused together.

In 1986, American scientist Charles Hull developed the first commercial 3D printing machine, however, it did not print metal materials.

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

Qin Tao nodded: "Now, this technology is blank for the time being, which also gives us an opportunity. If we can overcome this difficulty, then we will be able to mass-produce various titanium alloy parts in the future without worrying about various welding. We need parts of any complex shape, as long as they are input into the printer, we can make them! This will be our technology for cornering overtaking!”

Qin Tao spoke eloquently, because he knew that domestic research in this field of technology was advanced. The Americans started researching it in 85, but they had to give up because they couldn't figure out the technology of rapid metal solidification. In China, it has persisted for more than ten years, and finally succeeded. In 2005, J-3 used the first parts produced by [-]D printing technology. Even large aircraft components can be printed.

Compared with open die casting, it saves a lot of cost, improves efficiency, and can be applied to other aspects, eventually becoming a technology that the public needs.

"We have heard of this technology, but it is too difficult to study." The student continued: "We need to melt the consumable quickly, which requires a laser beam or a high-power electron beam, and then quickly solidify it. Layer upon layer. Right now, we have no theoretical basis whatsoever."

Qin Tao's eyes lit up, and the other party explained these difficulties clearly, which meant that he knew it!

"That's right, there is no difficulty in doing scientific research." Qin Tao said: "Our Mingzhou Shipbuilding Industry Group plans to establish a new research institute to specialize in the application of titanium alloys. Mr. Cao, do you want to try it? "

Mr. Cao sighed: "Mr. Qin, they all say that you are far-sighted. Seeing is worth seeing. Your knowledge is quite good. 3D printing technology is indeed very promising, but it requires a lot of investment. You Now, do you want to fund our research in this area?"

"Yes, we contribute funds, you contribute technology, and jointly conduct research. Each will get half of the shares. After success, the profit will be divided equally. How about it?" Qin Tao said.

Their Mingzhou Shipbuilding Industry Group has developed very well now, and they can spare part of the funds to do research, such as 3D printing of titanium alloys. If there is a chance, Qin Tao will certainly want to get started.

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

He has money, but no technology. He is okay with warships, but with materials, he can only place his hopes on others.

The old Cao in front of him has studied in the field of titanium alloy for many years, and the people under him are all elites. If these talents can help him, it would be great.

Cao Lao looked at his students: "Xiao Wang, what do you think?"

"Teacher, in fact, I have already discovered the advanced nature of 3D printing technology, but I have no way to get involved. Now, with this opportunity, I want to try it." The student said: "My whole life, Wang Hua, as long as I do If one thing is accomplished, it is considered an achievement.”

Wang Hua?

Qin Tao was surprised for a while, what is this called?
Stepping through the iron shoes, there is nowhere to find it, and it takes no effort to get it!

The Wang Hua in front of him is still Cao Lao's apprentice, so what could be wrong, this person must be the inventor of domestic 3D printing technology!If you fund him to do this project yourself, the success rate is [-]%!

"Well, since you want to do it, then do it, but I have a suggestion." Mr. Cao looked at Qin Tao: "You don't have a research and development atmosphere here, you can put this research and development organization in a university , you can hang the brand of your Mingzhou Shipbuilding Industry Group, and then each will own half of the shares."

Qin Tao originally planned to do it in Mingzhou, but this is not a big city after all. Excellent talents like to stay in a big city, so he thought about it and nodded.

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