Zhao Yanyan knew that Guo Tailai had this batch of gold, but he just didn't see it.

When talking about cost before, it was because she got used to it when she was in the final assembly.

No matter what research or design is done, the first problem we face is the funding issue. The design cost is too high and the cost is too high. The solution that is definitely given up immediately.

There is no way, the country is still poor and the military expenditure is limited, so we can only make some helpless compromises in some aspects.

However, when a fat man makes these things by himself, he doesn't have to consider the cost at all, or he doesn't have to consider the cost first, and considers the technical feasibility first to be the most practical.

There is no way, putting 700 tons of gold in your hand is a huge reassurance, which is not counting the billions of dollars of Google shares that have just been disclosed.

In terms of funding, as long as the fat man wants to do it, it is not a problem at all.

The weight of gold, hundreds of tons of gold, worth billions of dollars, will definitely create the deep submersible that Guo Tailai wants.

Moreover, according to the size and displacement of the Russian nuclear-powered deep submersible, as long as three stringed metal ball pressure resistant chambers are actually not even one-eighth of the weight, and at most only 300 tons.

The Jiaolong has an empty weight of 22 tons, the Deep Sea No. 6500 has an empty weight of 26.7 tons, and the Alvin has a lighter weight of only 17 tons.

They are all single spherical pressure-resistant chambers, with an internal diameter of no more than two meters, and three people are required to ride. You can imagine how narrow the space inside is.

Because of its low overall weight and small size, it has limited personnel and equipment that can accommodate, and the underwater endurance of these deep submersibles does not exceed three days.

Of course, you may be able to stay in the "shallow sea" of thousands of meters. In the Mariana Trench, let alone three days, the pressure of loneliness alone in the deepest part of the earth is enough to make people collapse.

From this point of view, that guy James was alone and stayed in the Ocean Explorer that could collapse at any time for eight hours, which was admirable.

Especially at the deepest point, some accessories have been crushed by the terrifying water pressure. He can still quietly enjoy the scenery of the seabed inside, which is worthy of the title of "madman".

Guo Tailai will definitely not be as "worry" as him. Since he wants to build it, he must build it larger and have a more spacious space.

You can bring more equipment and life-saving systems and stay underwater for a longer time. To put it bluntly, you can bring more oxygen.

If you even need it, you can sleep underwater. Three spherical pressure-resistant chambers with a diameter of three meters are more than enough to sleep in each of them.

It would be fake if Zhao Yanyan wanted to say that he was not excited.

The fat man insisted on doing this stubbornly, not because the space is large and comfortable, but because he wanted to make technical reserves for the research and development of similar equipment in China in this way.

Whether it is large titanium alloy ball casting or forging, there must be equipment of this level and size. With the help of Fatty production, these technologies can be studied in advance.

Of course, there is also large titanium alloy hemisphere welding, and the same is true.

As for other buoyancy materials, survival systems, battery and power systems, safe escape systems, and very important water acoustic communication systems that need to be used, we must study them in advance, and there will definitely be some useful things in the future.

Guo Tailai has done this kind of thing more than once, including the "Sky Three Bounces" helicopter and super yacht in front, and now he needs to add a deep submersible.

If the fat man really makes all these things, then the domestic units studying the Jiaolong may be a little embarrassed.

However, this is not a big problem. After all, the other party is not as rich as the fat man who invests at all costs. And then again, it has been awkward for some domestic R&D institutions once or twice. It is so embarrassing that it is so embarrassing that it is so embarrassing that it is so awkward that it is getting used to it.

"You requested a dive depth of nearly twice that, are you sure that the strength of the pressure chamber can withstand the pressure at the seabed?"

No longer worried about the cost, the senior sister asked a very critical question: "This involves your safety. If the test fails, I will never allow you to take it."

"The thickened titanium alloy sphere should be fine. The thickness is as high as 120 mm, and the pressure resistance is not a problem at all."

Guo Tailai knew his senior sister’s concerns and replied with a smile: “It’s just that the requirements for processing are higher.

Now we have a large 3D titanium alloy printer, which has been realized in three meters in diameter. It can be fully integrated molding, which is easier than welding two hemispheres. The welding of titanium alloy is not easy, and the integrated molding material is more uniform and has higher strength."

This is true. Zhao Yanyan also knows that the series of 3D printing projects hosted by the second brother of Guo Tailai dormitory of Zhengyifang Technology. Integrated printing is indeed more convenient than split casting and then welding them together.

"If you are still worried about the thickness being too large and difficult to process, a martensite high-strength nickel steel being developed by Zhengyifang Technology is about to be completed."

When Guo Tailai saw that his senior sister did not speak, he immediately continued: "This new alloy steel has twice the strength of tc4 titanium alloy, and can achieve compressive strength under thinner conditions.

It’s just that the cost may be increased a little, which is completely acceptable.”

The martensite high-strength nickel steel mentioned by Guo Tai is the pressure-resistant ballast material for the manned submersibles made in China in the future. The Rainbow Fish is designed to dive into the Mariana Trench, with a stronger structure and better performance.

Zhao Yanyan smiled bitterly when he heard this, and said that before his fat man did a lot of things, he had already completed a batch of pre-requisite technologies.

The pressure-resistant chamber has new materials, including titanium alloys, portholes and observation holes, generally highly transparent methacrylic resins are used, but Fatty Company has developed transparent metals long ago, with better performance.

The Jiaolong project team of buoyancy materials still needs to be customized from the UK in advance, but Zhengyifang Technology has been researching and developing the problems since the previous year and is almost completed, which is not a problem at all.

Guo Tailai has a supercapacitor that has been successfully developed but has extremely high cost, but is this a problem for fat people?

The biggest problem has been solved. There are some researches in the remaining working systems and water acoustic communications in China. Guo Tailai has also invested in it. The power system is also being developed by the research institute. It seems that everything else is production and assembly.

From this perspective, the fat man wanted to build an ideal three-sphere pressure-resistant shell manned submersible with no technical or equipment barriers. He just determined the design plan, produced and tested the assembly, and had to consider the cost.

"Don't make a decision first, you should do whatever you want to go back to Gusu."

The senior sister also lost her idea: "I will report this situation to my superiors soon tomorrow to see what their superiors think.
Chapter completed!
