I have a little black hole

Even if the dive depth of the'Strange Shark Class' nuclear submarine was discovered, countries with technical strength have worked hard to design and manufacture torpedoes that can dive so deep, the attack effect is definitely not as good as that, because at a depth of 2000 meters Here, if you want to have enough attack power under such strong pressure, the torpedo can be built as big as a submarine!

This is why the last time Kuafu said that he would start building the'Shark Shark' nuclear submarine, Lei Tiantang only asked him to build two ships for testing, and even after the test was completed, he only planned to produce a total of 6 ships. It’s enough for such a nuclear submarine to have this size, and there is no need for more.

Because with the technology currently mastered in the world, the "Strange Shark" nuclear submarine is almost synonymous with invincibility, and even the ability to find it is not available, because even when it is propelled at full power, the maximum noise is only 80 decibels, under ordinary cruise conditions. The noise does not exceed 75 decibels at most.

The noise can even be reduced to 65 decibels when using battery energy to propel the hidden propulsion!

The advantage in this respect comes from the more advanced battery manufacturing technology that Lei Tiantang has mastered. The high-performance battery system not only makes the propeller rotate faster, but also brings better noise reduction effect to the nuclear submarine.

This noise is almost the same as that of a normal person speaking, much lower than the average noise value of the seabed!

The background noise of the ocean changes with the sea state. Generally, the background noise compared with the submarine evaluation refers to the background noise of the ocean in the third-level sea state, which is about 100 decibels.

The quietest of the attacking nuclear boats in active service is the old and beautiful "Virginia" class, the noise is unknown, but it is said to be quieter than the 95 decibels of the "Sea Wolf". The quietest of the strategic nuclear boats is the polar bear "God of North Wind" class, The noise is about 100 decibels, which is said to be quieter than the quietest "Ohio" class before.

From these data, we can compare the advancement of the noise management of the "Strange Shark Class" nuclear submarine, and such low noise is due to its propulsion method, which uses the "motor propulsion" method.

This is the use of steam provided by a nuclear reactor to drive a turbogenerator to generate electricity, and then deliver electrical energy to a high-power motor. The operation of the motor drives the propeller to rotate to achieve the purpose of submarine navigation.

"The limit test can begin! Let's do the limit dive depth test first?" Kuafu asked after all three nuclear submarines officially drove to the sea where the deep dive test can be conducted.

"Yes, finish the test as soon as possible!" Lei Tiantang said, leaning on the special commander seat of Kuafu after taking a sip of iced Coke and waving.

Of course, he did not sit in those two "submarine shark class" nuclear submarines to be tested, but took a "electric eel" class nuclear submarine, its maximum diving depth reached 1200 meters, enough to follow behind for testing Data recording is working.

It’s not that he’s worried about safety. Even if he doesn’t open a nuclear submarine, he can use his ability to dive down to the deepest sea floor on the earth, but the two test nuclear submarines are not prepared to entertain them. There is not even a chair that sits comfortably on a'electric eel' class nuclear submarine, so why be comfortable if you can?

"Please! Boss, can you be more serious?! Have you fully grasped all the details of our new submarine? Don't wait for the deep dive limit test to fail, you can't recover!"

If it were not for your approval, I could only build two, and I built ten or eight of them in one go. I don’t have to wait for your grandfather to start the experiment. The experiment is over!Kuafu said loudly.

"Get out! Even if we have more resources, we can't be so wasteful! You're going to ruin ten or eight nuclear submarines for a test? If this thing is used to sell money, at least 10 billion will be sold. U.S. dollars?

Throw 100 billion dollars in an experiment. You really don’t want to use bean bags as dry food!"Lei Tiantang went back.

"Cut! Why don't you say a ship worth 100 billion US dollars? Isn't it more meaningful to say that?! Even if it's worth so much money, are you willing to take them out and sell it?" Kuafu's projection turned over Said with a white eye.

"That might be it! In case we have no money in the future, it is not impossible to sell it one by one, people still have to eat it!"

"Boss, are you disgusting? Do you say that your conscience hurts? Doesn't you say you are worth now? The pile of gold in your storage space is not enough for you to eat?

Hurry up, don't pull the calf, if no problem, I will start directly!"Kuafu spit out his mouth without a face.

"Cut! Selling gold and selling nuclear submarines are two good feelings? Forget it, don't talk about this, I don't plan to sell anyway!

You can dive in peace!I am very skilled in such simple things, and I promise not to drag you behind!"

Lei Tiantang didn't even care about his vomiting, and after Dun Dun Dun's dry mouth, he signaled him to start quickly.

Kuafu is not nonsense. He directly operated two'Shark-Sharp' nuclear submarines and began to dive at a constant speed from the current sea level of 1000 meters. The two nuclear submarines dive together to maximize the collection of comparative data, which can make the test data more Valuable, this is also their consistent means of doing experiments.

As the submarine descended deeper and deeper, the sensors installed on various places on the submarine kept transmitting data back to the'electric eel' class nuclear submarine, and the real-time data refreshed constantly on the projection screen .

"Huh! You said that if we publish the data of our nuclear submarine, people outside can believe that this data is really not?" Lei Tiantang was happy after watching the submarine's dive depth reached 1900 meters. Asked.

"It's as if you plan to announce it! It's not necessary to believe that the data of the "electric eel" class nuclear submarine we are going to publish now, let alone the one we are testing!

At present, the maximum diving depth of a nuclear submarine is only in the early 1000 meters, which is also achieved by sacrificing a lot of the combat effectiveness of the nuclear submarine. It must be known that below 1,000 meters below the sea surface, the pressure that the submarine needs to bear will rise to a step every 1 meter. Yes, the submarine may sink if there are any minor problems."

"The same is true, if the material performance is not good, you can only sacrifice combat power to resist the pressure of the sea water." Lei Tiantang replied casually.

His attention has always been on the two nuclear submarines. Through the data projected by the absolute field and Kuafu, he saw that their current depth has exceeded 2,000 meters. He shouted happily: "Haha! Yes! Both At this depth, the shell has not been damaged!"
