"Deep-sea submersibles and submarines dive in the same way, both inject seawater into the air chamber. Pen, fun, pavilion www. biquge。 When the submarine floats, it will use compressed air to force out the seawater in the air tank, while the deep-sea submersible will use compressed air to force out the seawater in the air tank due to the deep dive and high environmental pressure, so it will use the method of discarding the ballast iron to achieve the floating. ”

"It is worth noting that deep-sea submersibles generally control ballast iron through electromagnets, so in case the deep-sea submersible loses power and the electromagnet fails, the ballast iron will automatically detach from the submersible under the action of gravity and make the submersible float. ”

After a pause, David continued: "The pressure of 5,000 meters underwater is equivalent to 500 atmospheres, which is equivalent to the weight of 5,000 tons on an area of 1 square meter.

Fang Yuanshan knew this, but he had only swept away reading books before, and he didn't have an intuitive understanding. At this time, when he heard the explanation of "Tank", his face changed. Under such a large pressure, the hull of the submersible can be a depth test.

"What about its materials? Under such a large pressure, ordinary materials can't bear it!"

"Well, at present, new composite materials are mainly used, as long as it is within its diving regulations, there is no need to worry about compression. ”

Today, New Zealand's "Uncle Sam" asked the manufacturer to send the deep-sea submersible over, looking at the big round ball in the container, Fang Yuanshan thought of a question, and then asked: "What about the power of this thing? How to sneak underwater, and what is the range?"

The engineer who came with him also stood beside him, and when he heard him ask such a question, he couldn't help but turn his eyes to David for help. David was also a little helpless, his boss thought of a play, and spent millions of dollars to buy a submersible, without asking how to use it.

Seeing that the boss was still waiting for his answer, he shrugged his shoulders and said: "Boss, I'm sorry to tell you that the main technical difference between a deep-sea submersible and a submarine is that the deep-sea submersible is not completely autonomous, and must rely on the mother ship to replenish energy and air. ”

"What do you mean?"

"Uh... To put it simply, you also need to buy a matching big boat. Then, at the end of each dive, the submersible is recovered back to the mother ship, rather than traveling independently in the sea. You should see that this deep-sea submersible is small, has a short range, and does not have the living facilities of a submarine like a submarine. ”

David's meaning is very clear, just such a big thing, and you have to consider safety, and you need to equip electronic equipment and ballast, and it also has a certain endurance, what do you want?

"I... Damn, I spent millions to buy an iron lump back?"

The engineer next to him was a little embarrassed, and said with a red face: "Also... The same cannot be said of it, at least the things in it are the most advanced in the world. ”

"Forget it, you teach me how to use it~"

Fang Yuanshan, who was depressed for a while, finally followed the engineer up to the container, which contained some scattered external instruments and equipment in addition to an overall shell. After the engineer opened the hatch and entered the cabin, he explained to him the purpose of each button and how to operate it. Finally, he said: "Mr. Fang, I suggest you buy a mother ship produced by our company, which will have a great effect on the later use of submersibles." ”

"How much?"

"Uh... It's not expensive, about $4.5 million~"

"No need, I'll go back and play with this submersible at home~"

“。。。。 ”

The engineer looked like he had eaten a fly, and finally said helplessly: "Okay, if Mr. Fang has any questions, you can call me at any time, I will stay in Rio for a week." ”

"Okay, let's go, I'll study it myself~"

After the engineer left, Fang Yuanshan's face did not show any expression of disappointment. In fact, it doesn't matter to him whether this submersible has power or not, he may have needed it to sneak in the deep sea before, but now he has space to move, as long as he wraps the submersible and "runs" ahead...

After Frank and the others saw that there was nothing to do, they began to prepare to go to Colombia one by one, and Jonson Lance and the little American girl were all driven away by him, leaving only him and a few delivery masters.

There was no need for external connections to the mother ship or submersible, and the group drove the container towards Villa 1 in Copacabana, where a hoisting machine was already waiting on the dock.

When the container came, several workers connected the buckle, and then went into the water with a "boom". The owners of those yachts and cruise ships basically knew Fang Yuanshan, and when they saw him come over with an iron bump, they came over and asked one by one.

"Hey Fang, what are you going to do here?"

"Mr. Fang, are you a new yacht?"

“。。。。 ”

Many of the people who came around were company owners and chairmen in the business district, and in addition to curiosity, these people were more interested in befriending him. After all, Fang Yuanshan is worth tens of billions, and he is "kind", and he has no shelf, if he encounters something in the future, as long as it is not too outrageous, according to this person's character, it is estimated that he will not die without help.

Although it was already more than four o'clock in the afternoon, the sun in the sky was still hanging high in the sky. Tourists from afar want to lean over when they see such a big movement here, but unfortunately due to the fact that there are too many people on the beach recently, the marina has been controlled, and ordinary people can't enter, so they can only watch from afar.

Fang Yuanshan, who was standing on the pier, said with a smile on his face at this time, with a smug expression: "Hey, it's not interesting to always play cruises, I've been thinking about going to the bottom of the sea to have fun recently, why don't you buy a deep-sea submersible, how about it, okay?"

There are no less than 100 cruise ships of various types on the yacht docks here, and there are even more in the entire Rio State, but so far, Fang Yuanshan is probably the only one who plays underwater submarines. This courage to be the first suddenly made the bosses and chairmen next to him flattering, and he couldn't stop laughing.

The water is still being adjusted, and among the tourists watching from afar, a beautiful figure came over at this time, with a slender figure, fair skin, and a high bun with the taste of a noble lady.

Seeing a large group of people gathered here, this "noble lady" took off the wide-brimmed sunglasses on the bridge of her nose, and a standard beauty face was revealed, which was the uninvited "Bai Fumei".

Bai Rui is naturally no stranger to cruise yachts, she has seen more or less domestic yacht clubs, and she also has an ultra-luxury cruise ship at home. After looking at it twice, she was not interested, and was just about to put on her sunglasses and leave, when a familiar figure came into view in the distance.

"Hey, isn't that guy, why did you get here?"

To say that the reason why Bai Rui came to Brazil, in addition to Fang Yuanshan showing her a magical "magic" on the plane, there is also a reason that she has never been to Brazil, so this time she came here to play a circle temporarily. And to be honest, Fang Yuanshan's feeling to her was too mysterious, which made her have a desire to "see the whole picture".

Seeing Bai Rui, who was an "acquaintance", his eyes looked at the side, and he found a white man who looked like a local, walked over and asked with a smile in English: "Hi hello~"

Accosted by a fairly beautiful woman, the young white man bared his white teeth and smiled back: "Hi beauty, what's the matter?"

"Do you know what that Chinese guy in a white shirt on the dock does?"

The man subconsciously glanced in the direction she signaled, and when he turned around, he said disapprenosingly: "Oh, you said Fang, he is the owner of Villa No. 8." ”

Bai Rui blinked and asked, "What else?"

The white man, who originally thought that there was something "good", looked at her, and then looked at Fang Yuanshan in the distance, and suddenly understood. The relationship between the two is Chinese, and this chick can't figure out that party. He spread his hands and said, "I'm sorry, I don't know anything else~"

Without waiting for Bai Rui to reply, the white man followed: "This young lady, how about I invite you to have a drink?"

"Thank you, no need~" After speaking, she walked in the direction of Fang Yuanshan...
