Chapter 233 Submarine-launched anti-ship missiles

  In the era of submarines, the main weapon they used was the torpedo, which was an underwater weapon to attack the enemy. However, torpedoes also have many disadvantages.

  For example, the speed is slow. Even if the speed of the torpedo reaches 30 to 40 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 sails underwater after all, and its weapons, except torpedoes, are nothing else.

   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. 8!

   "We have also tried the anti-ship missile launched by the submarine, which 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 However, after the test, it is outdated, so it has not been used in large quantities."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 8, the navy also transformed an old-fashioned 033 submarine. There are 6 anti-ship missile launchers installed at the front and back, forming a significant bulge.

  When submerged, these launching devices are flat. When it is necessary 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 original 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 40 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 some results have been achieved." Zhang Lao continued.

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

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 to 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 submarine carrier like a torpedo, 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, each technical problem has finally been overcome. Now the 092 nuclear submarine is ready for combat readiness. Therefore, it is not a big problem to transplant the technology.

   "You mean, during the development process of our new generation of nuclear submarines, submarine-launched anti-ship missiles will be used 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."

   Torpedoes will be used to hide and seek with submarines of other countries in the future, 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 8 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 100. 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, but 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.

  Old 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: "How 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 hurriedly humbled.

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

   When it comes to surface ships, the old man is no match for the Americans, but when it comes to underwater power, the old man is definitely strong enough. The Oscar nuclear submarine is one of the masterpieces. What is the inside of a shark with tens of thousands of tons?

  Mr. Zhang really wanted to go and see it.

   "Do you want to see it? Next time I find a chance to take you to see it, what a joke." Qin Tao said generously. For him, it doesn't seem to be a big deal.

  Qin Tao made some introductions and arrangements 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 soundly.

  The next day, early in the morning, he was woken up again, and the day's work 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. Beside him, a large group of people were reporting to him on the work during this period.

   "The natural gas ship has been put into operation normally, and the shipowner has responded very well. Other colleagues have also seen our construction quality. It is estimated that new orders will come in soon."

   "The catamaran yacht has finished building its shell and is undergoing interior decoration. Would you like to take a look?"

   "The gantry crane has been erected, and the dock is preparing to start construction. However, the geological survey is not very 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.

   Just like that, on the way to the berth, Qin Tao saw Wu Shengli and others, and showed a wry smile.

   "Well, 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.

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

   "Well, invite him to the conference room." Qin Tao is very satisfied, the topic brought up yesterday, today the experts came over.

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

office.

  Qin Tao looked at the person who appeared in front of him, and respected him immensely: "Mr. Cao, I never expected that they would invite 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 meeting room and started communicating in a friendly atmosphere.

"Old Cao is an authority on titanium alloys in our country. I remember that in 1956, 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, 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 been able to use 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 need 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.

  The oxyacetylene flame is the fastest, but 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 sparks flying, but when cutting titanium alloy, you must not see sparks, otherwise the material will be scrapped.

  A submarine has 600 tons of titanium alloy. How long will it take to slowly cut it open?

  Qin Tao felt the urge to vomit blood.

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

  Although they are all titanium alloys, they are quite different. There are a lot of specifications such as TC4, TA15, TA7, TA5, Ti-75, TA12, TA18, TA19, etc. You must first know the specific composition of this titanium alloy.

"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 20% 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 20% off is quite astonishing.

   "20% off? I think many departments will thank Mingzhou Shipbuilding Industry Group." Mr. Cao said to Qin Tao: "Especially our fighter manufacturing requires more and more titanium alloys."

In the J-8 currently being produced in China, the amount of titanium alloy is only 2%. When the J-10 is reached, it will be increased to 4%. When the localized Su-27 is the J-11, the amount will be increased to 10%. five.

The proportion of titanium alloy used is getting higher and higher, and the price of aircraft is 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 80%. Can save a lot of money.

   "Teacher, if we use these second-hand titanium alloys to build 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, if you use these second-hand titanium alloys to rebuild parts, you 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 you have a brain pain and go to the hospital to take a CT scan, 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, hearing Qin Tao talk about 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 1985, 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-11 used the first parts produced by 3D 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 showed 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 provide funds, you provide technology, and jointly conduct research. Each will get half of the shares. After success, the profit will be divided in half. How about it?" Qin Tao said.

   Their Mingzhou Shipbuilding Industry Group has developed very well now, and they can definitely spare part of the funds for research, such as 3D printing of titanium alloys. If there is an opportunity, Qin Tao certainly wants 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 can do warships, but he can only rely on others for materials.

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

  Old Cao 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?

   There is no place to find if you break through the iron shoes, and it takes no effort to get it!

  Wang Hua in front of me 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 100%!

"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."
