Chapter 335: The Flood Dragon Enters the Sea (Part 2)
The importance of the propeller to the stealth of the nuclear submarine really plays a vital role. The entire nuclear submarine is like a person swimming in the water. During the swimming process, the human body itself will emit the sound of the beating heart and the flow of blood.
The sounds made by the bones and the sounds made by the feet touching the water, and the sounds of the heart and blood are equivalent to the noise made by the nuclear power plant of the nuclear submarine, and the sounds made by the bones are equivalent to the transmission system of the nuclear submarine.
The noise produced, the waving sound of the feet, is equivalent to the noise produced by the propeller at the tail of a nuclear submarine.
There is no doubt that the biggest noise comes from the feet and feet, and the sounds made by the heartbeat, blood flow, and bones are easily annihilated by the background noise in the water. Therefore, once the noise of the propeller is suppressed, the entire
The stealth of nuclear submarines will be greatly enhanced
This is why propellers are so important for nuclear submarines. Never think of propellers as a very ordinary metal part. In fact, many countries have mastered the pressurized water nuclear reactor technology suitable for use on nuclear submarines, but only high-end
In the manufacturing of propellers, only the United States, Germany and Japan are at the top of the world. Even Russia lags far behind, not to mention China.
However, the emergence of Dongchen has completely solved this long-standing problem that has plagued the development of nuclear submarines for many years. China has spent a total of twenty years to mature its technology in the field of seven-blade inclined propeller manufacturing. However, even
When it was most mature, it was far away from Western countries, but it only took Dongchen less than half a month to produce two 11-blade large side-inclined propellers that are absolutely the best in the world. Among them, the propeller alone
The technology has improved for at least 40 to 50 years overnight!
After the 094 was equipped with an eleven-blade large canted propeller, the noise performance has been infinitely close to that of the American Ohio-class nuclear submarine. Although the Julang-2 submarine-launched missile on the 094 is still far behind the American Trident, in terms of survivability
It is said that 094 has become the top of the world overnight!
The military is very satisfied with the performance of the 094, and the next highlight is the performance of the new submarine after being equipped with the Dongchen 11-blade large side-inclined propeller!
The overall scientific and technological strength of the new submarine is nearly ten years more advanced than the 094. Every technology applied to this large nuclear submarine with a displacement of 10,000 tons can be said to be the pinnacle of China's industrial manufacturing strength. However,
Before Dongchen developed the eleven-blade large canted propeller, this new submarine was only better than the 094 in terms of tonnage, sonar, electrical system and power performance. However, the missile it carried was still the Julang with a range of only 8,000 kilometers.
Type 2, the propeller installed at the tail is still an unadvanced seven-blade large side tilt technology.
Two long-standing problems with nuclear submarines have been taken up by this new submarine. The range of submarine-launched missiles is insufficient and the noise on the seabed is huge. But now, this new submarine, equipped with an eleven-blade large canted propeller, is slowly moving like a ghost.
Enter the detection area
At a depth of three meters and a speed of 7 knots, the new nuclear submarine has been cruising in the detection area for about an hour. The sweating sonar operators could not find any information about the submarine. Sometimes, there was a sudden sound from the sonar.
The sound made them feel nervous, but after pursuing it, they found that the source of the noise was not the submarine they were looking for.
The commander-in-chief did not rejoice prematurely, but immediately said: "Let the 'Ghost' continue to sneak around in the designated detection area, and immediately request Haining Air Force Base to dispatch anti-submarine aircraft to cooperate with the test!"
"yes!"
This time, the commander-in-chief will use all his strength to track down the whereabouts of this submarine ghost. Anti-submarine ships, anti-submarine aircraft, and anti-submarine helicopters will use almost all their anti-submarine capabilities. This is obviously beyond the limit.
Anti-submarine capability in wartime, because no nuclear submarine would be stupid enough to stay in the opponent's detection area and wait for the opponent to use all its capabilities.
However, if the whereabouts of the new submarine cannot be found despite such a trinity of anti-submarine coverage, it means that the stealth of this submarine will reach the top of the world's nuclear submarines, and even directly rival the Ohio class.
With China's current anti-submarine technology, it is very difficult to accurately detect cutting-edge strategic nuclear submarines like the Ohio class. The Ohio is a sharp arrow for the United States' nuclear attack. Its survivability can be said to be the king of nuclear submarines. Chinese nuclear submarines are
In terms of survivability, what is worse than the Ohio is not only the propeller technology, but also the multi-in-one silencer technology of the entire submarine. However, if the propeller of the Chinese nuclear submarine is stronger than the Ohio class, then it can make up for the gap in other parts.
Anti-submarine aircraft and anti-submarine helicopters took off in an emergency. Twenty minutes later, the anti-submarine aircraft was already cruising over the detection area. Three anti-submarine helicopters arrived thirty minutes later. However, after half an hour of searching for so many anti-submarine equipment, nothing came of it.
Still no trace of the submarine was found.
The commander-in-chief suppressed the excitement in his heart and blurted out: "Inform the 'Ghost' to free play. The purpose is to rush out of the detection area. Once it rushes out of the detection area, today's test mission will be successfully completed!"
The ghost received the silent signal wave. After receiving the command, it stopped cruising around the detection area. Instead, it adjusted its course and aimed at the farthest point in the detection area to sneak. This was equivalent to increasing the difficulty of the breakthrough mission.
At the limit, the speed was carefully lowered to 5 knots. At this speed, the ghost cruised for three hours before slowly rushing out of the detection area.
The sky was getting brighter, and the communication staff shouted excitedly: "Report, the ghost has shared the coordinates and completely rushed out of the detection area, requesting the next order!"
At this time, the scene really exploded. Everyone hugged each other excitedly, and some even cried with joy, just like the first atomic bomb exploded, the first artificial satellite went into the sky, and the first intercontinental missile test was successful.
Because these people know that today is definitely an epoch-making day for the entire country's national defense technology!
Whether it is 094 or a new type of submarine with no confirmed model, their stealth capabilities have changed from the bottom of the previous ranking to the top of the world. The United States has been repeatedly promoting that China's submarine silent capabilities have exceeded the United States' detection capabilities, but the military
But they have been making fun of the huge noise of Chinese submarines. Now, their threat theory has come true. I am afraid that the concealment capabilities of the new submarines have truly exceeded the detection capabilities of the United States!
It had been a hard night, but everyone was so excited that they couldn't contain themselves. The commander-in-chief gave the order in ecstasy. All anti-submarine aircraft and anti-submarine ships returned. 094 and the new submarines returned directly to the dock for rest.
At the same time, the results of this test were immediately reported to the ears of senior officials in Yanjing. Both the military and the government were extremely excited about this earth-shattering good news. In the encrypted telegram sent, they not only highly affirmed
This test is a huge advancement for the entire national defense force, and it also expresses gratitude to Dongchen Group for its huge contribution to national defense technology.
Zhang Hao was satisfied in his heart. He did not want to directly participate in the manufacturing of military equipment, but he gave a considerable degree of help to national defense technology in this way. He knew in his heart that he wanted to be that irreplaceable person, not that person who tried to replace everything.
People, irreplaceable people, are of sufficient importance to anyone, but people who try to replace everything will eventually be destroyed. Therefore, while he is excited, he still stands firm in his position. He and Dongchen,
We will still not directly manufacture military equipment in the future.
In the eyes of senior officials, Dongchen has now reached a peak, whether it is his extremely powerful civilian car manufacturing capabilities, the dcc-1800a high-power diesel engine he developed for the army, or the Eleven that achieved excellent results in today's test
Ye Da's canted propeller, Dongchen has become a pie-in-the-sky treasure in their eyes. Maintaining this cooperative relationship with the military also makes the senior management's impression of Dongchen become better and better.
After getting ashore, Zhang Hao was arranged to rest in the guest house of the shipyard. When he woke up, it was already evening. Officer Liu knocked on Zhang Hao's door and said to Zhang Hao: "The food has been prepared in the banquet hall, and it will be held tonight.
At the celebration banquet, you are the person in charge of Dongchen, and you are also the only Dongchen member present today. We strongly invite you to attend."
Zhang Hao nodded and said with a smile: "I must participate in such a festive event."
Officer Liu smiled slightly and said: "The military's orders have come in again, including our current 094 and the new submarines under construction. The military wants to order a total of ten eleven-blade propellers of the same size from you.
The unit purchase price is 50 million yuan, two sets have been completed, and there are eight more sets that need you to deliver within half a year."
Zhang Hao smiled calmly and said: "It won't take half a year, it can be delivered within three months." After saying that, Zhang Hao said: "The price of 50 million is too high, we can't use so much, let's give it a 10% discount, 50,000
"
"Fifty thousand?" Director Liu shook his head helplessly and said with a smile: "You are so young, why do you always push out the money delivered to your door? Last time you also lowered the price significantly for the DCC-1800a. This time for the propeller,
You lowered the price again”
Zhang Hao shrugged and said: "Dongchen really doesn't lack this kind of money. Dongchen's anti-humidity and bone-setting patch produced by Dongchen Pharmaceutical has already opened the North American and European markets. This year's revenue can already exceed 5 billion."
U.S. dollars, a rough estimate, Dongchen Motors' annual revenue this year should reach one to one to five billion U.S. dollars. If I continue to expand production capacity and launch new models in the future, I am afraid it can reach 200 million U.S. dollars. It will definitely be no problem for the world's top five.
Okay, this little money is really nothing to Dongchen, but not charging any money at all seems to have destroyed the cooperative relationship between the two parties, so I will charge a rough cost price."
Director Liu laughed, patted Zhang Hao on the shoulder and said with a smile: "It's true that we are rich and powerful!" To be continued If you like this work, you are welcome to vote for recommendations, monthly votes, and your support is my biggest motivation
