Huating.

   "Mr. Qin, welcome to our Golden Sun Electric Vehicle Company." When Ma Ming heard the news of Qin Tao's arrival, Qin Tao had already appeared on the busy construction site, and he greeted him wearing a helmet.

   "Well, the progress of the project here is not bad." Qin Tao said, looking at the hook machines and cranes on site.

   "After the Huating government approved the land for us, our Mingzhou Group Infrastructure Company began to build factories in full swing, and we also began to purchase equipment to prepare for the establishment of automobile production lines." Ma Ming said: "President Qin, I am really not good at doing this. It would be great if you could send someone here to help me."

  Ma Ming is engaged in research and development, and now he is in charge of handling the large and small affairs of such a car factory. He is really too busy. At the beginning, Mr. Qin said that he would directly get a second-hand car factory and produce it directly. Who would have thought that he would change his mind later and build a factory by himself?

  Starting from scratch, there are too many things to do. Fortunately, the problem of the birth certificate has been solved by purchasing the certificate of the closed automobile factory, which can be regarded as paving the way for the development of electric vehicles.

  Qin Tao nodded: "Well, I will recruit a few construction and management talents from the automobile industry. In the future, you will still be mainly responsible for the design. A bunch of large and small affairs in this production plant will be handled by professional people."

  Ma Ming nodded: "That's right, there are specializations in the arts."

   "By the way, how is the electromagnetic gun project going?" Qin Tao asked.

   "This project is a hard nut to crack, especially the issue of gun barrel abrasion." Ma Ming said: "Mr. Qin, you also know that I am engaged in electromechanical, not cannon. This is completely interdisciplinary. We are taking the route of coil guns, which is so difficult. The Americans are said to be taking the route of rail guns, and their abrasion is even more serious."

  Qin Tao nodded: "Yes, this is a big problem. If we can't solve it by ourselves, we can cooperate with other organizations. By the way, how about 713 Institute?"

   The most professional artillery manufacturer in China is, of course, the No. 2 Machine Factory on the grasslands. Almost all of them manufacture large and small artillery. However, they mainly focus on ground weapons, and the navy's naval guns are not much involved.

  The 713 Institute is mainly engaged in equipment for the navy. Their flagship products are all kinds of naval guns. For example, the single-tube 130mm naval gun used by the main destroyers is their masterpiece. But in the close-in defense gun, the 630 naval gun they developed has been replaced by the 730 naval gun of external energy, but this still cannot change their leading position in the field of naval guns.

  Since Mingzhou Group’s main business is building warships, it has a good relationship with Institute 713, which is in charge of making guns. Now that it has encountered a problem that cannot be solved, of course it has to ask a brother unit for help.

   "Okay." Ma Ming said: "It would be great if we can cooperate with the naval artillery unit. Mr. Qin, when are we going to leave?"

  Looking at the construction site under construction, Qin Tao said: "Now, anyway, you are not good at the work in front of you, and the people in our infrastructure company are responsible."

  So, Ma Ming and Qin Tao went northward together, and rushed to the 713th place.

   "Our electromagnetic gun is supposed to use the electromagnetic principle, but it still has abrasion problems." Along the way, Ma Ming was talking endlessly: "The main reason is that the speed of our shells is too fast. Even if it only accelerates to Mach 7, it is more than 2,000 meters per second. At such a fast speed, the heat generated by the friction between our shells and the barrel is quite high."

  Qin Tao nodded: "That's right, this is the main technical problem of the electromagnetic gun. In fact, the speed of Mach 7 is only the current index. In the future, the higher the speed, the better. After all, if we want to anti-missile, the speed must be as fast as possible. It is best to be able to fire continuously."

   How to install the guidance system on the warhead of the electromagnetic gun is a difficult problem. If it can’t be solved temporarily, it can only fly by inertia. If you want to accurately hit the missile in outer space, you have to fire a few to create a barrage, just like a rapid-fire gun.

   "Burst?" Ma Ming shook his head: "The current technology is too difficult to do."

  The two of them were chatting about various technical routes along the way, and in the evening, they came to the 713 Institute.

  Knowing that Qin Tao was coming, Xia Bei waited at the door early in the morning.

   "Boss Qin, you've worked hard all the way." Seeing Qin Tao get off the car, Xia Bei hurried up to greet him: "Our canteen has already prepared a reception banquet, are you hungry all the way here?"

   Before Qin Tao could answer, Ma Ming had already said: "We ate in the car, now, can we call your technicians for a meeting?"

  Ma Ming is a man of action. He came all the way to Office 713, thinking about how to solve technical problems as soon as possible. After getting off the car, he thought about holding a meeting to solve the problem.

   "Listen to Magong, let's have a meeting. If you don't come up with some constructive suggestions, Magong probably won't be in the mood to eat your reception." Qin Tao said.

meeting room.

   "At present, the muzzle velocity of the 130mm naval gun we have developed is less than Mach 3. Now the velocity of the shell has more than doubled, and the wear and tear on the barrel is indeed a big problem." After listening to Ma Ming's introduction, Xia Bei also frowned: "Now, let's talk freely, let's see how to solve this problem."

   "If we want to reduce wear, can we use magnetic levitation technology to keep the shell suspended in the barrel at all times to reduce wear?" A technician in his thirties asked below.

   "Magnetic levitation? This technology is still immature and requires low-temperature superconductivity to realize, but our naval guns will definitely heat up after firing shells, which will have an adverse effect on the cooling of superconductors." Ma Ming shook his head. In fact, they also thought about this solution, but it was also the first technical route to be ruled out.

  This is still a coil gun. If it is a rail gun, it is even more impossible to realize. The rail gun needs both ends to be in contact with the track. This suspension reduces friction, but it cannot be touched, and it cannot run at all.

   "If this is the case, then we can change our thinking and wrap a special material on the shell to reduce friction." The technician said again: "The friction between hard metals is very serious. What if we use a special material?"

   "This technology also has flaws." Of course, Ma Ming's team has also considered it: "After our shells fly out of the muzzle, they fly in the air at a speed of Mach 7. The shells will rub against the air, and the surface temperature will rise to thousands of degrees. If we wrap a layer of special material on the outside of the shells, after flying out, the material will rub against the air to generate heat, and may even burn, which will have a negative impact on our warheads."

   "It's simple. After flying out of the muzzle, the material wrapped around it can just fall off, just like our armor-piercing shells with a special shell outside."

   Ma Ming's eyes suddenly brightened.

  Why didn't I think of it?

   After all, he is not a cannon maker. At the beginning, building electromagnetic catapults and the like was completely within his scope of knowledge. This time, making cannons is out of his original scope of knowledge. He has been thinking about it for a long time, but he is not professional enough.

  Coming here really opened up new ideas for him!

   "Yes, this is a solution to the problem." Ma Ming was very excited: "We can try it!"

   "Ma Gong, should we continue our meeting here first? I don't think everyone has eaten. Shall we go to eat first?"

   Ma Ming nodded: "Okay, let's go eat first, brother, what's your name?"

  When discussing this project just now, this technician was almost always communicating with Ma Ming. The other party had a broad mind and a flexible mind. He was definitely a very powerful technician.

   "My name is Zhang Jian." The other party answered.

  Zhang Jian?

  When Qin Tao heard this name, his heart skipped a beat. If he remembers correctly, this guy is probably also a person who betrayed the interests of the country.

   "Zhang Jian has been working for 90 years and has always been the main force of our 713 Research Institute. He has played a huge role in the process of our research and development of various naval guns." Xia Bei said: "Currently we are developing the 130mm ultra-long-range gliding guided artillery shell. Zhang Jian has played a huge role. He proposed that the canards of the shell should be deployed after the shell flies over the apex of the trajectory, so that the zero angle of attack resistance of our shell is 10% lower than that of the red land. The range should exceed 100 kilometers."

   Obviously, Xia Bei is very satisfied with this technician.

   "One hundred kilometers?" Qin Tao opened his eyes wide: "Why haven't I heard of it before?"

   "We haven't reported it to our superiors. After all, our navy has a large number of soldiers and various advanced weapons are constantly appearing. We only invented an ultra-long-range gliding guided shell, which is nothing." Xia Bei was very humble.

   "No, your shells are of great significance." Qin Tao said: "Your 713 has made great contributions to our navy."

  Ordinary 130mm naval guns have a range of no more than 30 kilometers when firing ordinary shells, but for a naval gun, this is enough. After all, naval guns are designed to deal with low-intensity conflicts, and there are missiles at long distances.

   But missiles are expensive after all, not as cheap as artillery shells. Now, the 713 Institute has developed a brand new naval gun. With the brand new artillery shells, it has achieved a range of 100 kilometers.

  For the Dongfang Navy, this means that it is outside the range of the Xiongfeng 2 missile. The current maximum range of this missile is only 80 kilometers. Its own destroyers can fire from 100 kilometers away, which is very safe.

  Xia Bei smiled: "Boss Qin, since you know, let's wait for you to report this news to the navy leadership."

   "When I go back to the capital, you all go with me and report to the naval leaders in person. It just so happens that our 052D has not been outfitted yet, so we can just use this kind of naval gun and shells directly."

  Ma Ming was not interested in these things. He came down from the rostrum and came to Zhang Jian's side: "Zhang Gong, would you like to join our electromagnetic gun research and development team to jointly research this brand-new naval gun and expand the range from 100 kilometers to 400 kilometers?"

  Qin Tao frowned, Ma Gong, do you know who you invited? This person is likely to leak our secrets.

  But it is not convenient to say now, he can only continue to ask Xia Bei: "Has Mr. Zhang ever drank foreign ink?"

   "No, he joined our research institute after graduating from university, and has always been in the front line of scientific research. It is a pity that he can't go abroad for further study. Recently, our institute has an opportunity to visit abroad and plans to..."

  Qin Tao breathed a sigh of relief: "Old Xia, going abroad is dangerous. You have also seen that people like Max almost can't come back when they go abroad. Talents like Zhang Jian, it's better to stay in China."

   "This..." Xia Bei disagreed. Who is Max and who is Zhang Jian?

  For many people, they still hope to go abroad and see the outside world. Mr. Qin said that, that would cut off Zhang Jian's way to go abroad.

   "Let's go, let's eat." Qin Tao changed the subject.

  Ma Ming was not keen on eating and drinking, and even resisted it, but today he had a very happy meal. Zhang Jian was directly called to his side, and the two of them ate while saying that other technicians were going to become green leaves.

  Xia Bei and Qin Tao were sitting together, they were eating and talking at the same time, they were talking about the development of the navy.

   "At present, the Western world led by the United States is developing 155mm naval guns." Xia Bei said: "The larger the caliber, the longer the range and the greater the power. Mr. Qin, you have always said that our navy will have a large 10,000-ton ship in the future. For this kind of warship, do we need to develop a new generation of large-caliber naval guns?"

  In the past, the domestic navy commonly used dual-mounted 100mm naval guns. The technology was backward. Later, the French 100mm naval guns were introduced.

  Until the introduction of Hyundai-class destroyers, China began to set the caliber of the next-generation main gun at 130mm. Warships with a displacement of more than 6,000 tons can carry this kind of naval gun, but what about warships with a displacement of 10,000 tons? Is there a need for a larger caliber warship?

  The West has already begun to develop 155 mm caliber naval guns. Can our own side also fail?

   "This depends on the development of our electromagnetic gun. If the development of the electromagnetic gun goes well, then our navy's next-generation naval gun will be the electromagnetic gun." Qin Tao said: "If you want to develop the next-generation naval gun, the navy may not invest. It must be self-raised. If the navy does not want it, the huge investment will be in vain."

   "Mr. Qin, if the navy doesn't want it, can we export it? We have electromagnetic guns, and they must be for our own use. We won't export them for a long time, right?"

   "Yes, electromagnetic guns will definitely not be exported in the future, but the displacement of our export-oriented warships will not be large, and the caliber of the naval guns will not be too large. It is estimated that it will be difficult to export 10,000-ton warships. You must be prepared not to sell them."

  Xia Bei thought for a while, and then said: "We still want to try, even if it's just as a supplement to our electromagnetic gun."

  Qin Tao nodded: "Okay, your spirit is precious, and I support you spiritually!"

  That night, everyone stayed in the 713 guest house. Ma Ming lay on the bed, still unable to sleep: "During the meal, Zhang Jian and I talked a lot. I think this flick support plan may really be a correct technical route for our electromagnetic gun."

   "Have you talked about whether we are taking the technical route of coil gun or rail gun?" Qin Tao asked on the other bed.

   "Not yet."

   "Next, in the process of our cooperation with the 713 Institute, we will mainly study this abrasion problem and improve the materials of the gun barrel and shells to try to solve this problem. However, we try not to disclose the technical principle of our electromagnetic gun. We can even do some fake actions, such as adding contact points at both ends of the bullet stock to disguise it as the principle of a rail gun."

   Ma Ming immediately became serious: "Mr. Qin, are you trying to prevent our technology from being leaked? Are you afraid that 713 will steal our technology?"

  Qin Tao shook his head: "The 713 Institute won't do this, but after all, this is not our own company. We have to guard against technology leaks. What if someone here can't resist the temptation of sugar-coated bullets and leak our key electromagnetic gun technology to foreigners?"

   "Understood, Mr. Qin, I will pay attention."

  Of course, Ma Ming knows the weight of Qin Tao's words. He doesn't want to see his technology leaked abroad, but risks are everywhere.

  Mingzhou Group's technicians are well paid, and they often carry out patriotic education. They generally don't need to leak secrets, but other military units are different. After all, their income is not high, and they are easy to be attracted by the outside world.

  Low income is a problem, but this is definitely not a reason to betray the motherland. However, someone will always be attracted. This is a war without gunpowder smoke, and it will never stop. Just looking at Qin Tao, how many people have been poached from abroad with high salaries.

  713 is helping to solve the problem of abrasion, which cannot be kept secret. If Zhang Jian helps to solve the problem, if he wants to tell these secrets to foreign organizations, Qin Tao can't stop him. However, even if foreign countries get this kind of technology, it is impossible to tinker with electromagnetic guns, because the principle of rail guns brings huge technical problems.

   Still rely on the advantages of the technical route to win the opponent, and overtake on the curve!

   "Boss Qin, if we recruit these people who helped in the development into our Mingzhou Group, pay them high salaries, and provide them with various educations, will we be able to prevent accidents from happening? Zhang Jian is an excellent technician. I don't want him to go astray."

   "Ma Gong, aren't we poaching the corner of 713 by doing this?" Qin Tao said helplessly: "If it is really poached, will anyone dare to cooperate with us in the future?"

   Ma Ming is helpless, yes, this is really a problem.

   "We can provide them with an extra bonus to make their money easier." Qin Tao said the most suitable way.

  The next day, Ma Ming continued to stay at Institute 713, and started detailed research with Zhang Jian and other technicians, and even made prototypes, while Xia Bei came to the capital with a lot of technical materials.

  With Qin Tao leading the team, Xia Bei could directly meet a large number of naval leaders, and even held a special hearing.

   "Back then, we imported red land laser-guided projectiles from Damao. Now, this technology has finally blossomed and borne fruit here." After hearing this, Wu Shengli was very emotional: "We never even dared to think of projectiles with a range of more than 100 kilometers before."

   "Yes, we didn't dare to think about it before. In recent years, our domestic electronic technology has advanced by leaps and bounds, which has laid the foundation for our improvement, especially the development of our Beidou system. Now we can use this navigation and positioning system to improve the accuracy of our shells." Xia Bei said.

  Although GPS is more useful, this system belongs to the Americans. Once it comes to war, it is likely to be controlled by the opponent. Once the signal is cut off, your own shells will be useless.

  Red Land is laser-guided, but it is not easy to use a laser beam to aim at a target more than 100 kilometers away. This product produced by 713, in addition to laser guidance, also has a built-in satellite positioning module. It is more convenient for the army to use.

   "It's not just rocket propulsion and gliding that can hit so far. The naval gun itself has also been improved. For example, the length has been increased from the original 56 times the diameter to 70 times the diameter." Qin Tao said aside: "I think that the 052D destroyer we are building can be directly installed with this kind of naval gun. From the perspective of progress, it just catches up."

   "Yes, let's test this naval gun on our test ship first, and wait until the 052D is launched for outfitting." Wu Shengli made a decision on the spot: "This naval gun will become our mainstream naval gun for a period of time in the future."

   Seeing the support from the leaders, Xia Bei became more and more courageous. He took out another document: "Leaders, we still have a design plan for a 155mm naval gun. I would like to ask the leaders to correct it."

   "155mm naval gun? It's very similar to our army's howitzer." A leader immediately spoke.

   "It's just that the caliber is similar. There is a big difference between our navy's naval guns and the army's artillery. For example, we don't have to worry about weight restrictions, and we can arrange larger bomb bays and bomb supply systems. Our gun barrels can be water-cooled to achieve a sustained rate of fire. Our multiple diameters can also be larger, so that the shells can fly farther." Xia Bei opened the conversation and introduced it endlessly.

   "It sounds like our navy really needs to develop a new generation of naval guns."

   "That's right, the American DDG-1000 is using naval guns of this caliber. As the main ground strike force, we can also try it!"

   Hearing everyone's affirmation, Wu Shengli said again: "Lao Xia, our navy is poor. It is very difficult to support the construction of several warships, and we are often in arrears of funds. If you want to develop this kind of naval gun, we may not be able to allocate funds for you."

   "Leaders, we are willing to raise funds to develop it ourselves." Xia Bei said.

   "Okay, then our navy will support you spiritually!" Wu Shengli immediately made a decision.

  As long as the navy doesn't pay for it, it's easy to say! If domestic scientific research institutions are like this, then they can only wish for it.
