Chapter 877: Create or not (below)


Zhao Yanyan knew that Guo Tailai had this batch of gold, but he didn't see it.
When I talked about the cost, it was because she was used to the assembly.
No matter what research or design is done, the first problem that is first faced is funding. The design cost is too high, and the plan that is too expensive is definitely the first to give up.
There is no way, the country is still poor, and military spending is limited, so we can only make some helpless compromises in some areas.
But fat people do these things by themselves, without having to consider costs at all, or without first considering the issue of costs, and considering the technical feasibility first is the most practical.
There is no way, seven hundred tons of gold is in your hands, and that is a huge peace of mind, which is not even the billions of dollars of Google shares that have just been disclosed.
In terms of funds, as long as the fat man wants to do it, it is not a problem at all.
Equal weight of gold, hundreds of tons of gold, worth billions of dollars, can definitely create the deep submersibles that Guo Tailai wants.
And according to the size and displacement of Lao Maozi ’s nuclear-powered deep submersible, as long as three stringed metal ball pressure tanks, in fact, not even one-eighth of the weight was reached, at most only 300 tons.
The Nine Dragons had an empty weight of 22 tons, and the Deep Sea 6500 had an empty weight of 26.7 tons. The Alvin was lighter with an empty weight of only 17 tons.
All are single spherical pressure-resistant cabins with an internal diameter of no more than two meters, and three people must be seated. It is conceivable how much space there is.
Due to the low overall weight and small size, the limited personnel and equipment that can be accommodated are not limited to three days.
Of course, you may be able to stay a few kilometers in the "shallow sea". In the Mariana Trench, let alone three days, the lonely pressure of that person in the deepest part of the earth is enough to cause people to collapse .
From this point of view, the guy James was alone in the ocean explorer that could collapse at any time for eight hours, and he couldn't help but admire him.
Especially at the deepest level, some accessories have been crushed by the horrible water pressure, and he can still enjoy the scenery of the sea floor quietly, which is worthy of the title of "crazy".
Guo Tailai will certainly not be as "aggrieved" as he is. Since it is to be made, it must be made larger and the space is more spacious.
You can bring more equipment and life support systems, you can stay underwater for a longer period of time, to put it plainly, you can bring more oxygen.
You can even sleep underwater if needed. Three spherical pressure-resistant cabins of three meters in diameter, each of which is more than two.
Zhao Yanyan would say it was not exciting that it was false.
My own fat man has to insist on doing this, not because the space is comfortable, but he wants to use this method to make technical reserves for the research and development of the same type of equipment in China.
Whether it is large-scale titanium alloy ball casting or forging, there must always be equipment of this size and size. With the production of fat people, these technologies can be researched in advance.
Of course, there are also large titanium alloy hemisphere welding, and the same is true.
As for other buoyant materials, life support systems, batteries and power systems, safety escape systems, and very important underwater acoustic communication systems, all must be studied in advance, and there will be times when they can be used in the future.
Guo Tailai has done this kind of thing more than once, including the "air three jumper" helicopter and the super-yacht in the front. Now he has to add a deep submersible.
If their own fat people really make all these things, the domestic research unit of the Dragon may be a little awkward.
However, this is not a big problem. After all, the other party does not have such a wealthy investment regardless of cost, and then again, their own fatties have embarrassed some domestic R & D institutions not once or twice. I'm used to it.
"The dive depth you requested is close to twice this. Are you sure that the strength of the pressure tank can withstand the pressure on the sea floor?"
No more tangled up in cost, the sister asked a very critical question: "This is related to your safety. If the test fails, I will never allow you to ride."
"Thickened titanium alloy spheres should be fine. As long as the thickness exceeds 120 mm, the pressure resistance is not a problem at all."
Guo Tailai knew the sister's concerns, and smiled and replied, "It's just that the processing requirements are higher.
Now that we have a large 3d titanium alloy printer, the diameter of three meters has been achieved, and it can be completely integrated. It is easier than welding two hemispheres. The welding of titanium alloy is not easy. The integrated molding material is more uniform and stronger. . "
This is true. Zhao Yanyan also knows that the series of 3D printing projects hosted by the second brother of Guotailai Dormitory of Zhengfang Science and Technology, integrated printing, is indeed more convenient than split casting and then welding together.
"If you are still worried that the thickness is too large to be processed, a martensitic high-strength nickel steel that is being developed by Zhengyifang Technology is about to be completed."
Guo Tai came to see her sister and said nothing, and immediately said: "This new alloy steel is twice as strong as tc4 titanium alloy, which can completely achieve compressive strength under thinner conditions.
It may just be a little more costly, which is totally acceptable. "
Guo Tai said that this martensite high-strength nickel steel is the pressure-resistant cabin material for the future China-made Rainbow Fish manned deep submersible. The Rainbow Fish is completely designed to dive into the Mariana Trench, and the structure is stronger. Better performance.
Zhao Yanyan listened to a bitter smile, and co-authored a series of pre-technical research before finishing a lot of things with his own fat man.
The pressure chamber has new materials, including titanium alloys. Portholes and observation holes are generally made of highly transparent methacrylic resins, but fat companies have already developed transparent metals for better performance.
The buoyant material Nine Dragons project team also needs to be customized from the UK in advance, but Zhengyifang Technology has already researched and developed key problems from the previous year, which is almost completed, which is not a problem at all.
Guo Tailai has a super capacitor that has been successfully developed but the cost is still very high, but is this a problem for fat people?
The biggest problem has been solved. The remaining working systems and underwater acoustic communication are being studied in China. Guo Tailai has also invested in it. The power system is also being developed by the research institute. It seems that all that remains is production and assembly. Already.
In this case, the fat man wants to build an ideal three-sphere pressure-resistant shell manned submersible without technical and equipment obstacles, but only determines the design plan and production and assembly inspection, and has to consider the cost.
"Don't make a decision first, what to do back to Gusu."
Sister also had no idea: "I will report this situation to my superiors tomorrow and see what my superiors think.
However, I don't think it will allow it. Even if the three spheres are connected, the Russians will think of the nuclear submarine, and the state will not allow you to take the initiative to be in danger. "
