Although the simulated torpedo launched from the side was only more than 30 meters away from the test model boat, the active sonar power on the simulated torpedo was reduced year-on-year by computer calculation

That is, although it is a distance of tens of meters, but according to the calculation of the year-on-year reduction of sonar power, it is equivalent to a distance of tens of kilometers in the ocean.

The first generation of nuclear submarines was also tested first, and the first simulated torpedo entered the water, although the first generation of nuclear submarines was stationary suspended in the water, but when the torpedo turned on the active sonar search target, it hit the prototype model directly without any hesitation.

The next is the submarine installed with the silencing tile, this is the time to really test the function of the silencing tile, the main function of the silencing tile is to reduce vibration, and absorb sound frequencies, etc., as another simulated torpedo was launched, it also quickly turned on the active sonar to search for the target, but surprisingly, this torpedo did not track directly as just now, but automatically moved forward according to inertia, and began to circle in the water.

This means that the torpedo's active sonar does not find the target and begins to expand the search range on its own until the active sonar finds the target, or the torpedo's fuel is exhausted. It wasn't until the simulated torpedo approached the target more than ten meters away from the test boat that the active sonar found the target, and the simulated torpedo collided directly with the test boat, until the two collided together, and Lou Tingyu, who was full of excitement like a child, jumped up violently and shouted at the staff next to him: "Go, return to the original position, re-test, this time let the test boat move at a year-on-year speed equivalent to the speed of the old section." ”

"Yes, Lou Lao." The staff next to them were not stupid, of course they knew what this meant, and several people immediately began to convert the torpedo and the test boat into manual operation, and put the simulated torpedo back into the launch tube, where someone was naturally responsible. After about ten minutes, the test restarted, but this time the test boat was moving at a slow speed, which was about the same as the old knots when it zoomed into the ocean.

But just like the result just now, the active sonar of this torpedo still did not find the simulated boat, and it entered the same state as before, but this time it was even more different that after the torpedo entered the automatic search and began to expand the search range, when it was about close to seventeen or eighteen meters, it found a test boat that was moving slowly and hit it directly.

"Data record keeping, again, this time the active sonar rate when the torpedo is launched, the efficiency is increased by a level." Lou Tingmian quickly said to the staff next to him. The staff member was stunned for a moment, and then asked tentatively: "That old Lou, our original simulated power has already been simulated according to the most advanced torpedo in the world, and if it is expanded in this way, it will be much more advanced than the most advanced torpedo in the world." ”

"Do it!" Lou Tingyu immediately glared at the staff member and said loudly.

"Yes, yes, yes!" The staff member did not dare to refute and immediately went back to re-operate. The results of this test were not as good as the previous two times, when the torpedo had just entered the water, although the active sonar did not find the target, but only expanded the search distance of less than four or five meters before the target was revealed, and it directly crashed into the simulated boat.

"Record the data, do the next tests, and do all the tests three times!

Save all the data, and it's strictly forbidden to talk about things today, if you don't want the national security to find you for tea. Lou Tingyu glared at all the staff and said loudly.

These people work here, although it is a laboratory of a private enterprise, but there is also a confidentiality agreement here, the difference is that it is not as strict as a national research institute, but they also know what today's test means, and these people are usually experts in this field.

"Xiao Yang! You have made a great contribution to the country! Lou Tingyu turned his head and directly stretched out his hands to hold Yang Yiwei's hand, but this first sentence made Yang Yiwei a little cute, these older generation of people engaged in scientific research are really cute, and the patriotism in their mouths is sincere.

"Lou Lao, this is what we should do." Yang Yiwei looked at the building seriously and listened to the rain meter.

"Well, well, very good, this model is a little rough, but even so, I'm sure that your anechoic tile is not only unattainable in China at present, but it is unknown whether the American anechoic tile can reach your level, I don't have specific data in the United States, I don't care, but I have a few old friends who can call up the actual data! After three tests, if it's all like this, you've definitely made an epoch-making invention! And, do you know what it means to make a submarine? If the propeller of the submarine is made of the latest type of high-damping alloy shock-absorbing and noise-reducing propeller, according to the test just now, the active sonar effect of the torpedo in the whole world will be weakened by at least 60 percent! Lou Tingyu spoke excitedly like a child, and was a little incoherent.

But Yang Yiwei still understood, he got these data from Konishi, so he was not too excited, in fact, this material is not too perfect, according to Konishi's words, the equipment is too successful, and the manufacturing can reach about 80% of the perfect state at most, although 20% is not necessarily much improved, but in submarine warfare, sometimes a decibel is the difference between life and death.

Lou Tingyu said that Yang Yiwei has seen the high-damping alloy from Xiaoxi, but at present, Yang Yiwei does not have the strength to get it, if you want to be higher than that alloy, at least you have to invest close to the nPS of Xinyi or above to upgrade the equipment! And some equipment is not sold to you to consider it, but the domestic catch-up in this regard should be very fast, since the word came out of Lou Lao's mouth, this proves that some research institutes have begun to study, since they have begun to study, it means that the basic equipment is basically up to standard.

The three times of the test was quickly done, the test results of the three times were similar, Lou Tingyu was completely excited this time, although the silencer tile could not strengthen the role of its own submarine sonar, but the ability to absorb sound and shock absorption was simply too strong. Although the active sonar power of the submarine is much more powerful than that of the torpedo. Although there are many ways to search for torpedoes, at the bottom of the sea, the most reliable way for torpedoes to search for targets is still active sonar and passive sonar.

Although the submarine can input the torpedo into the target, let the torpedo reach a certain area and then turn on the active sonar, but it can weaken the active sonar effect of the torpedo, which is equivalent to weakening the active sonar of the opponent's submarine and passive sonar!

According to Lou Tingyu's calculations, if the latest type of domestic nuclear submarine is equipped with this kind of silencing tile nose and a new type of high-damping alloy propeller, I am afraid that the minimum noise of the submarine will reach a record 7

Decibels or so! This is already lower than the background noise of the ocean, and the possibility of being discovered by the other party is not only greatly reduced to what can be described in a sentence?

"Xiao Yang, do you need to marry me to help? If you need my help, you can speak, I can still contact some old friends, although they have all retired, but they have been rehired by various research institutes as technical consultants, they still have a certain right to speak, otherwise it will be difficult for your material to enter the sight above. Lou Tingyu said seriously.

Yang Yiwei was overjoyed, he didn't expect this kind of unexpected gain, originally Yang Yiwei wanted to ask Lulu's mother to help after the test, Lulu's mother is the chairman of the largest private shipbuilding factory, and she must know people in this area, and then ask them to recommend it after contacting it. The second is to prepare to directly take these test records to apply for a patent in China! What is the role of the Sweeping Bureau in addition to accepting patent applications?

There is also the responsibility of discovering some patents that are useful to the state and are at the level of secrecy! Prevent these patents from applying for international patents, because once you apply, you are bound to provide some materials to the various countries of the international patent contract, and press down these applications, anyway, just file them in the country, because China is also one of the contracting countries of the international patent contract, and if you apply for it in China, it is equivalent to having entered the procedure, and it is useless for others to apply.

However, in this way, it depends on whether the person who accepts the patent is responsible, after all, they can't understand all the techniques, and they are not insured, and now Lou Tingyu is an expert in this area, if he can contact some old friends, it is naturally the best way! The right to speak of these old experts is very unusual, and these people do not have those utilitarian intentions, and getting the recognition of these people means that they are a big step forward from the order!

"Lou Lao, Xie Lu thank you, but I think I really need your help, because we are just an ordinary small company, even if we research it, we can't know people in this area, so we still need your help to introduce us."

On behalf of all the staff of Xingshen Company, I would like to thank you for your help. Yang Yiwei bowed seriously.

Lou Tingyu laughed twice, and then patted Yang Yiwei's shoulder excitedly: "You don't need to say Xie Luxie, it should be me on behalf of all the researchers of our generation to say thank you Xie Lu!" We have struggled all our lives in the hope of designing a truly strategic submarine, although we have worked hard and have made countless breakthroughs, but we have to admit that there are still some gaps from European and American powers! Although I have not been in this circle for many years, I still know that even the latest 0Q class is far from the American Seawolf class in terms of noise. There is even a gap to the nuclear submarines of the Virginia class. (To be continued)
