Invincible Smart-Guy System

Propeller plays a very important role in the secrecy of nuclear submarine. The whole nuclear submarine is like a person swimming in the water. In the process of swimming, the human body will make the beating sound of heart, the flowing sound of blood, the sound of bones in motion, and the sound of hands and feet pulling water. The sound of heart and blood is the same as the sound of heart and blood The noise produced by the nuclear power equipment of the nuclear submarine, and the noise produced by the skeleton, is equivalent to the noise produced by the transmission system of the nuclear submarine, and the noise produced by the wave of the hands and feet, is equivalent to the noise produced by the propulsion propeller of the tail of the nuclear submarine.

There is no doubt that the biggest noise comes from hands and feet, and the sound of heartbeat, blood flow and bones is easily annihilated by the background noise in the water. Therefore, once the noise of propelling propeller is suppressed, the secrecy of the whole nuclear submarine will be greatly enhanced.

This is also why propeller is so important for nuclear submarine. Do not regard propeller as a very common metal part. In fact, many countries have mastered the PWR technology suitable for use in nuclear submarine, but only Germany and Japan are among the top three countries in the world in the manufacture of high-end propeller, and even e country is far behind China, of course, let alone.

However, the emergence of Dongchen has completely solved the long-standing problem that has plagued the development of nuclear submarines for many years. China has spent a total of 20 years to continuously mature its technology in the field of manufacturing seven leaf large skew propeller. However, even when it is most mature, it is far away from the western countries. However, it took Dongchen less than half a month to produce it Two of them are absolutely the world's top 10 large skewed propellers. Among them, the technology of propellers alone has been improved for at least 40 or 50 years overnight! After the 11 blade propeller was installed, the noise performance has been infinitely close to the Ohio class nuclear submarine of the United States. Although the julang-2 submarine launched missile on 094 is far from the trident of the United States, in terms of survivability, 094 has been ranked at the top of the world overnight!

The military is very satisfied with the performance of 094, and the next important play is the performance of the new submarine after replacing with the large side inclined propeller of Dongchen eleven leaves!

The overall scientific and technological strength of the new submarine has been nearly ten years ahead of 094. Every technology applied to the large-scale nuclear submarine with a displacement of 10000 tons can be regarded as the peak of the military manufacturing strength of China. However, before Dongchen did not develop the 11 blade large oblique propeller, the new submarine only had tonnage, sonar, electronic system and dynamics In terms of force performance, it is better than 094. However, the missile it carries is still the julang-2 with a range of less than 8000 km. The propeller it is equipped with at the tail is still an advanced seven blade large sideslope technology.

Two old and difficult problems of nuclear submarine are occupied by this new submarine. The range of submarine launched missile is insufficient and the noise on the sea floor is huge. Now, this new submarine, which is equipped with 11 blade large side inclined propeller, enters the detection area slowly like a ghost.

At a depth of 300 meters and a speed of 7 knots, the new type of nuclear submarine has been cruising in the detection area for about an hour. The sonar men who are sweating all over can't find any information about the submarine. Sometimes, the voice suddenly comes out of the sonar and makes them feel nervous. But when they catch up with it, they find that the source of the noise is not the submarine they are struggling to find.

The commander-in-chief did not rejoice too early, but immediately said, "let the ghost continue to prowl in the designated detection area, and immediately ask Haining air force base to send out anti submarine aircraft to cooperate with the test!"

"Yes!"

This time, the commander-in-chief is going to make full use of all his horsepower to pursue the whereabouts of this submarine ghost. The anti submarine ship, anti submarine aircraft and anti submarine helicopter have used almost all their anti submarine skills, which is obviously far beyond the anti submarine strength in wartime, because no nuclear submarine is stupid enough to stay in the detection area of the other side and wait for the other side to All the abilities are available.

However, if the whereabouts of the new submarine can not be found in such a trinity anti submarine coverage, it means that the secrecy of the submarine will reach the top of the world's nuclear submarine, or even be directly comparable with the Ohio class.

With the current anti submarine technology of China, it is very difficult to accurately find the Ohio class advanced strategic nuclear submarine. Ohio is the sharp arrow of the U.S. nuclear attack. Its survivability can be said to be the king of the nuclear submarine. On the one hand, the survivability of China's nuclear submarine is worse than that of Ohio, not only the propeller technology, but also the elimination of the whole submarine Sound technology, but if the propeller of the porcelain nation nuclear submarine is stronger than that of the Ohio class, it can make up for the gap in other parts.

The anti submarine aircraft and anti submarine helicopter took off in an emergency. Twenty minutes later, the anti submarine aircraft had been cruising over the detection area. Three anti submarine helicopters arrived in thirty minutes. However, after half an hour of searching for so many anti submarine equipment, no shadow of the submarine was found.

The commander-in-chief suppressed the excitement in his heart and blurted out: "inform the" ghost "to play freely. The purpose is to rush out of the detection area. Once it rushes out of the detection area, today's test task will be completed successfully!"

The ghost receives the silent signal wave. After receiving the command, it stops cruising around the detection area, but adjusts its course, aiming at the farthest point in the detection area, which is equivalent to adding the difficulty of breaking through the task to the limit. On the side of caution, the speed of the ghost drops to 5 knots. At this speed, the ghost cruises for three hours before slowly rushing out Detection area.

As the sky began to light up, the communication personnel shouted excitedly, "report, the ghost has shared the coordinates, and has completely rushed out of the detection area, asking for the next order!"

This time, the scene is the real frying pan. Everyone embraces each other excitedly, even some people cry with joy, just like the first atomic bomb explosion, the first man-made satellite to the sky, and the first intercontinental missile test success, because these people know that today, for the national defense technology of the whole country, it is definitely a epoch-making day!

Whether it's 094 or the new submarine of undetermined model, their concealment ability has changed from the last place to the top of the world. The United States has been vocal in publicizing that the submarine silence ability of China has exceeded the detection ability of the United States, but the military has been making fun of the huge noise of China's submarines. Now, their threat theory has come true, I'm afraid that the stealth capability of the new submarine has actually exceeded the detection capability of the United States!

After a hard night, everyone was so excited that he couldn't help himself. The commander-in-chief gave an order in ecstasy. All the anti submarine aircraft returned, the anti submarine ship returned, and 094 and the new submarine directly returned to the dock for rest.

At the same time, the test results were immediately reported to the high-level ears far away in Yanjing. Both the military and the government were excited about the earth shaking good news. On the encrypted telegram sent, not only highly affirmed the great promotion of the test to the whole national defense force, but also named and thanked Dongchen group for its national defense science and technology Great contributions.

Zhang Yunfeng was satisfied and didn't want to directly participate in the manufacturing of military equipment. He helped national defense technology to a certain extent in this way. He understood that it was important for anyone to be the irreplaceable person, rather than the person who tried to replace everything. The person who tried to replace everything eventually Towards destruction, he is still firm in his position when excited. He and Dongchen will not directly manufacture military equipment in the future.

In the eyes of senior executives, Dongchen has now risen to a peak. Whether it's his powerful civil automobile manufacturing strength, his dcc1800a high-power diesel engine developed for the army, or today's ten one leaf large skewed propeller with excellent results, Dongchen has become a treasure like a pie in the sky in their eyes Fang maintained this kind of cooperative relationship, which also made the high-level impression of Dongchen better and better.

On the shore, Zhang Yunfeng was arranged to rest in the shipyard's Guesthouse. When he woke up, it was evening. Director Liu knocked on Zhang Yunfeng's door and said to Zhang Yunfeng, "the dinner is ready at the banquet hall, and a celebration banquet will be held tonight. You are the person in charge of Dongchen, and the only Dongchen member on the scene today. We strongly invite you to join us."

Zhang Yunfeng nodded and said with a smile: "such a festive event is bound to be attended."

Director Liu smiled and said: "the military's order has come down again, including our 094 in active service and the new submarine under construction. The military will order you 10 large-scale 11 blade oblique propellers of the same scale, with the purchase price of RMB 50 million. Two sets have been completed and eight sets need to be delivered within half a year."

Zhang Yunfeng smiled quietly and said, "it won't take half a year, it will be delivered in three months." Say, Zhang Yunfeng says again: "the price of 50 million is too high, can't use so much, give a discount, 5 million."

"Five million?" Director Liu shook his head and said with a smile: "you boy, how can you always extrapolate the money sent to your door? In the last dcc1800a, you also reduced the price by a large margin. This time, when it comes to spiral pulp, you will reduce the price again. "

Zhang Yunfeng shrugged and said: "Dongchen really doesn't lack this money. Now Dongchen is just the dehumidification Zhenggu paste produced by Dongchen pharmaceutical industry. It has opened the markets of North America and European Union one after another. This year's income can exceed 5 billion dollars. Roughly speaking, the annual income of Dongchen automobile this year should reach 10 to 15 billion dollars. If I continue to expand in the later period, I will be able to I'm afraid that we can reach 20 billion yuan by filling the production capacity and launching new models. It's no problem for the top 500 companies in the world. This money is really nothing to Dongchen, but it seems to destroy the cooperation relationship between the two sides without any money. So I'll take a roughly cost. "

Director Liu laughed and clapped Zhang Yunfeng on the shoulder and said with a smile, "it's not surprising that you are rich."
