C324 The Flood Dragon Has Entered the Sea(part I)
The developed countries are very strict on the confidential management of submarine propellers. Even a photo would not let outsiders see that all their submarines were built in the enclosed dock. They either directly entered the water from the dock or completely wrapped the propellers. Only after the submarines entered the water would they be dismantled. Everything was only to ensure that the secret of the propellers was not known by other countries as much as possible.
For example, some of the countries that produced the best strength, such as Germany and Dongwo. Their processing ability was not inferior to any country, even if it was just a simple image. It could also allow them to immediately discover the profoundness behind it. Even if they could not rely on the pictures to reach a height comparable to it, but at least they had the ability to get as close as possible.
The two sets of Eleventh Leaf Big slanted propellers that Dong Chen processed were tightly wrapped by the special canvas in the processing center. They were also loaded into the special wooden box to ensure that it was completely fixed and protected inside the wooden box.
These two sharp propellers were loaded into a heavy truck on the night of the second day. Furthermore, the two propellers were loaded into a heavy truck. Under the escort of the three Dongchen C3 SUVs, they headed to Haining. Haining was a port city near the ZhongHai, belonging to the Zhonghai. Here, there was the largest military port in the country as well as the military ship construction center.
Zhang Yunfeng was also in one of the three C3 cars. It was purchased from unk s by the state, and it belonged to the Nanjiang Province Armed Police Headquarters. Except for Zhang Yunfeng and Director Liu, all the people in the three cars, including those in the heavy truck... All of them were special policemen sent by the Armed Police Headquarters to carry out a top secret mission.
Even these special forces did not know what they were involved in escorting and transporting things. They only received orders. They must deliver two large wooden boxes with a width of six meters and two people in the car to Haining before dawn.
Zhang Yunfeng and Director Liu sat in the back of C3 and rarely talked along the way. Even if it was a conversation, the content had nothing to do with the propellers and nuclear submarines. However, both of them knew that when the two propellers arrived at Haining, after being loaded into the new submarine that was being tested, the technology of the entire country's submarines... They would enter a brand new era.
The City J was not far from the Zhonghai. Even to Hai Ning, it only took more than five hours. When he arrived at Hai Ning, the sky only lit up a little. When the motorcade just drove out of the highway, there were four cars waiting at the exit of the highway. The heavy truck was handed over to the soldiers who came to welcome them. Director Liu and Zhang Yunfeng boarded another domestic cheetah off-road vehicle. After that, all the special police officers of the Nanjiang River armed police received the order to immediately return to the original road.
These soldiers carried Zhang Yunfeng and Director Liu forward. They were at a port that was classified as a military restricted area. The car drove into a huge dock. The roof area of the dock was huge. And inside the roof, other than the various heavy equipment, a few different types of ships were parked in special grooves. The other end of the groove was connected to the sea. However, at this moment, the seawater was blocked by a thick isolation door.
The convoy passed through a few construction sites without lights on. When the car turned around a corner, Zhang Yunfeng's attention was completely attracted by what was in front of him.
It was a huge metallic object that was completely black and its entire structure was like a drop of water. Although it was only bald at the end, it appeared very sudden, and its overall shape could be said to be very domineering. As a fan of the quasi-army, Zhang Yunfeng had always been very curious and yearned for submarines. This was the most important weapon in the navy in the current world. They were far more practical than aircraft carriers.
The convoy stopped in front of the submarine construction site, and the engineers who had been waiting for a long time immediately began to unload the two large wooden boxes on the truck. The heavy crane on top of the submarine was already ready, waiting. It was these two unparalleled underwater weapons!
The leading experts who had returned from City J the day before immediately went up to Zhang Yunfeng and Director Liu, who had just gotten out of the car. One of the chief designers said excitedly, "All the participants of the project, after learning that we have the Eleventh Leaf Great slanted propeller, we have been waiting for this for a long time!"
He introduced the ship to Zhang Yunfeng and Director Liu. "This is the third generation strategic nuclear submarine that we are testing. The model has yet to be determined, and there is only this one at the moment. Two propellers, one of which will be used on this test submarine. There is also a level 094, entering the port at noon today, and then entering the maintenance dock. There, change another propeller, and the two submarines will enter the sea at the same time to test. Our water test ships and equipment have been prepared. We'll be able to go out to sea tonight. "
Director Liu couldn't help but say excitedly, "I wonder how much optimization these two propellers can make to the noise of our submarines."
The chief designer smiled helplessly and said, "The biggest problem of our submarine is the noise. Be it attacking nuclear submarines, strategic submarines, or even regular submarines, they all suffer the pain of noise."
Then he said, "Our 092, which is the first generation strategic nuclear submarine, is the first generation. The underwater noise reaches 165 decibels, and 094 is slightly better. About 140, E country's technology is a bit stronger than ours. Their active strategic nuclear submarines can basically reach the standard of 120 decibels. As for the Americans, their strategic nuclear submarines are the best, basically around 100110 decibels. "
At this time, one of the large wooden boxes had already been carefully dismantled. A group of top domestic engineers surround that big guy and look at it non-stop, also exclaiming non-stop. As the chief designer led the two of them forward, he began to explain. He said, "The ocean has its own base noise. Generally speaking, if the submarine's noise at the bottom of the sea is below 90 decibels, then... It's basically the same as the ocean's noise at the bottom of the ocean... This way, the submarine's ability to detect itself is extremely low, but this standard... Not even Americans could reach it. If someone could create a submarine with a noise lower than 90 decibels... That was simply heaven defying. There were all kinds of theories and boasts on the Internet all day long. It was said that the sound of which country, which country, and even porcelain countries' submarines had reached more than 80 decibels. That kind of rumor... When we heard it, we just laughed out loud. The submarine noises of various countries, decibels, decibels, decibels, etc... It's all top secret, except for the Americans who occasionally have the ability to monitor the submarines from all over the world... We can only estimate a rough number... Those who say the decimal numbers of submarines from other countries are even detailed to individual digits... Basically, you can choose to ignore it."
Zhang Yunfeng nodded thoughtfully. The noise of the submarines from other countries had always been the biggest limitation of the submarines' combat ability. American military experts had once mocked the porcelain submarines, saying that the porcelain submarines made noise in the coastal waters of the country. Even in Saigon, Vietnam, they could still hear it, although it was an exaggerated irony. However, it also highlighted the shortcomings of the porcelain submarines.
Then, Zhang Yunfeng asked, "When this new submarine uses a seven-leaf propeller, how much noise is it making?"
The chief designer did not keep Zhang Yunfeng and Director Liu a secret. Director Liu had enough status and power to understand these data at any time. Zhang Yunfeng was also the person whose superior had nodded and said that there was no need to hide anything. So... He said without hesitation, "This new submarine has made a breakthrough in the deceleration of noise. It uses the Seven Leaf propeller. The underwater noise is about 130 decibels, of course, I'm talking about low speed "
As he spoke, the chief designer smiled and said, "After equipping this advanced Eleven-leaf Grand slanted propeller, if the noise can be reduced by 20 decibels, then it will be a huge leap!"
Zhang Yunfeng was not sure about this because the submarine noise came from many aspects. Especially the nuclear aircraft carrier, it was huge in size, had a complex structure, and the power part was even more complicated. First was the nuclear reactor, then the steam generator, then the steam turbine. Then the transmission system and the propeller.
The general principle was that the hydraulic nuclear reactor burned the nuclear material to produce heat energy. It caused the water in the high-pressure state to reach thousands of degrees of high temperature without boiling and then produced a huge steam power through the steam generating system. Pushing the steam turbine, driving the propeller, the whole process... Not only was the structure complex, but it was also the source of the noise. Even though the Eleventh Leaf Great slanted propeller now had extremely high performance and noise reduction abilities, the noise from the other parts... There was still no improvement.
At this moment, an engineer ran over and asked the chief designer, "Director Qu, Engineer Liu asked me to ask you if you want to start the reactor now?"
The chief designer looked at the time and said, "It's not even six o'clock yet. Start at eight o'clock on time."
"Okay." The engineer nodded and immediately turned around to leave.
The chief designer said to Zhang Yunfeng and Director Liu, "The activation of the reactor takes about 13 hours. The main reason is to prevent the heat impact, so the temperature of the reactor will gradually rise. Activating the reactor at 8 o'clock, it should be ready by 9 o'clock at night. During this period of time, it will be enough for us to change into new propellers. As for the other 094, entering port at noon, the reactor will not be closed. Directly change into new propellers. At around 12 o'clock in the morning, the two ships will enter the sea at the same time."
The loading of the propellers was not a very difficult task. It only took less than two hours for the installation of the propellers to be completed. At eight o'clock in the morning, the reactor on the new submarine also started on time. Zhang Yunfeng and Director Liu were arranged to have lunch in the shipyard's canteen at noon. At noon, a nuclear submarine that had just served not long ago entered the port from the water.
094 had been installed for several years and was no longer news for western countries. Western countries already had a good understanding of this model of strategic nuclear submarine. Until now, so, 094 would normally return to the port to replenish its supplies. Entering the maintenance and resupply dock from the surface of the water, everything seemed to be very ordinary. However, no one knew that after the 094 entered the port... It was immediately equipped with the Eleventh Leaf Big slanted propeller designed by Dong Chen.
Zhang Yunfeng was very interested in the nuclear submarine. In fact, he had the world's best nuclear submarine. He had mastered all the manufacturing techniques of the Ohio nuclear submarines and even the techniques of the later generations of strategic nuclear submarines in Ohio. It was precisely because he had a sufficient understanding of nuclear submarines that Zhang Yunfeng was interested in these ghost-like weapons. He was extremely interested.
Strategic nuclear submarines were the kings of all submarines, and this type of submarine served as the only mission. Its strategic significance and practical significance... It was far more effective than any type of nuclear weapon.
For the current era of satellites, all land-based nuclear missiles... They were all exposed to the enemy. Once the war broke out, all land-based launchers and nuclear force bases would be the first target of the enemy's destruction. This was the importance of the pre-emptive strike in the era of nuclear weapons. Once the land base's nuclear weapons were completely sealed or even destroyed, then the country's nuclear counterattack could only come from the sea.
The ocean was vast, and it was even more mysterious, no matter how powerful the satellite was. It was impossible to monitor the entire ocean that occupied more than 71% of the world's surface area, and the nuclear submarine was a ghost that walked in the depths of the ocean. Therefore, it is the most powerful country in the world. It was also the hardest to destroy and the easiest to retain nuclear power.
The reason why it is called a strategic nuclear submarine is because its strategic significance is very significant. A strategic nuclear submarine carrying dozens or even hundreds of nuclear missiles... Swimming in the vast ocean, it supplies once... It was enough to ensure that it would remain in the deep sea for 90 days without floating. It was this kind of super sustainability. It ensured that once it entered a highly urgent state, the nuclear submarine could immediately hide in the oceans of the world before the war. Once a war broke out, the nuclear submarine could ignore the damage to the mainland. In any corner of the world, it would deal a devastating blow to the enemy.
With this thing, you will have the strength to fight to the death with any country in the world. It is because of this strategic deterrence that your enemies will be afraid of. That is why you can guarantee peace and control the development of the war.
The 094 nuclear submarine was not enough to pose a threat to a superpower like the United States. If 094 made significant progress, it might even surpass the Ohio level of the United States. Then, it would be no different from placing a time bomb next to the American pillow. Giving them enough intimidation.
Even if war did not happen, with such deterrence in hand, it was still a weapon to maintain peace.
The time they waited was not only for the builders, but also for Zhang Yunfeng. He could not help but feel excited. At 3 PM, the change of 094 was completed. At 9: 13 PM, the reactor of the test submarine was activated. After the underwater test a month ago, it was ready to enter the vast ocean once again.
In order to grasp the specific data immediately, Zhang Yunfeng did not request to take a submarine. Instead, he wanted to take a high-tech test boat disguised as a sea monitor boat. This test boat was actually the best anti-submarine in China.
At 11: 30 a.m., the test boat that Zhang Yunfeng and Director Liu took was the first to leave the harbor. Entering the deep sea region. Half an hour after they left the port, ... Two submarines sailed out of the dock at the same time and immediately dived into the water... They quietly followed behind the test ship.
In a depth of more than a kilometer, the test ship closed its engine and was almost motionless on the surface of the water, just floating up and down along with the waves. At this moment, in the monitoring room, dozens of people were busy working together.
The communications staff reported loudly, "Report, 094 speed is approaching 20 knots. We are about to enter the towing sonar detection area!"
The commander in charge of the test said, "Notify 094. Maintain course and enter at maximum speed. Don't stop!"
"Yes!"
Keeping 094 at maximum speed was basically the limit of its speed. The standard for submarine noise testing was usually 510 knots of low-speed stealth noise. It is impossible for a submarine to move forward at full speed in the enemy's detection area. Because moving forward at full speed, the noise would increase by several times.
However, the commander-in-chief naturally had his reasons for doing so.
About 20 minutes later, a staff member in charge of monitoring exclaimed, "The speed of 094 has reached 27 knots!"
"Good fellow!"
The commander-in-chief was delighted and blurted out, "Change into a new propeller. The maximum speed has increased from 25 knots to 27 knots!"
"It's still accelerating!" The monitoring staff said, "It's almost 28 knots!"
Everyone was overjoyed, with no changes to the power system. After replacing the new propellers, the maximum speed increased by nearly three knots. This meant that the thrust efficiency of the new propellers was higher than the previous seven-leaf propellers.
"28 knots, there's no room for improvement."
Even with the speed of 28 knots, it was still very delightful. At this time, the submarine had already entered the detection range of the test boat. The commander blurted out, "What's the noise readings for the rear end of the 094 detector?"
"220 decibels."
"[Yes.]" The commander-in-chief said excitedly, "Compared to the previous full speed state, the speed has increased by three segments, but the noise has decreased by 15 decibels. If the speed is maintained at 25 knots, I think the noise can be lowered by at least 5 decibels. The performance of this new propeller is indeed very powerful! "
After saying that, he ordered again: "Make 094 turn around and enter the field again. This time, we will enter the field at a low speed during wartime!"
This time, 094 lowered the speed to 7 knots. Everyone waited for more than 10 minutes before the messenger said: "094 has entered the monitoring range."
"Sonar!" The commander blurted out, "Activate all detection methods to determine the location of 094!"
The staff in charge of sonar detection continued to monitor. However, as time passed, half an hour later, they were still unable to determine the location of 094.
The sonar detector was sweating profusely, but other than them, everyone had an uncontrollable ecstasy on their faces. Until now, the sonar still couldn't find the location of 094. This proved that the stealth ability of the current 094 had been greatly improved!2
An hour later, at the silent scene, the excited roar of the communications staff suddenly rang out: "Report! 094 report, they have already appeared and are out of the surveillance range!"
With a boom, the scene instantly exploded. Everyone roared in excitement. The sonar tester who was previously at a loss was also excited to the point of being unable to control himself. They knew that they had tried their best. But... From the time 094 entered the arena to the moment it appeared, they hadn't found a trace of 094! This proved that the silent ability of 094 had already surpassed their anti-stealth ability! Although China's anti-submarine ability was somewhat inferior to that of the United States, Japan, and Germany, for 094 to have such a performance... It was also enough to make people excited!
