Great Warlord: The Second Ancestor of the Empire

No matter how worried Kameda Uhei is, it will not affect the scientific research progress of Daxia.

With a large amount of financial and material investment, the research progress in Daxia can be very rapid.

By 1922, scientists at the base had discovered the isotope of uranium 235 and began to think of ways to purify it.

Purification is actually relatively simple, but the difficulty is how to turn natural uranium ore, which has only 0.7% in nature, into highly enriched uranium with a content of more than 80%.

According to scientists' calculations, if you want to create a nuclear bomb, the purity of uranium-235 must not be less than 78%.

If it is lower than this concentration, it will not be achieved, and the effect of the explosion will be much reduced.

In order to avoid mistakes, the scientists set the standard at 80%.

This means that if you want to make the raw materials for nuclear bombs, the concentration must be increased to 80%.

One can imagine how difficult it is to increase from 0.7% to 80%.

What scientists now face is how to increase the concentration to 80%. For this, scientists at the base thought of using centrifugal force.

Therefore, some mechanical experts were separated from the large team and began to develop centrifuges.

You must know that this era is not the 40s, let alone the 60s.

Now Daxia is walking in a field that no one has ever touched before. Everything requires constant trying.

Lin Yi had already been mentally prepared for this, and he was very satisfied with the current progress.

However, Lin Yi also knew that even the standards set by scientists now are still far from the standards of future generations.

Let’s just talk about concentration. In later definitions, 3% is the fuel concentration used in nuclear power plants. At this level, it can already meet the standards for use in nuclear power plants, so this concentration is defined as "low-enriched uranium."

After that, uranium must reach 80% to be considered highly concentrated, which can be barely used to make weapons.

Only when the concentration reaches 90% is the most ideal raw material for nuclear weapons.

However, in this era, let alone 90% concentration, even 80% concentration has already made these scientists grow old.

The current situation is that scientists at the base have found uranium-235 and know how to enrich it, but they do not have the tools to enrich it.

To put it simply, it is stuck on the centrifuge.

From today's perspective, centrifuges are already very common, and the most common centrifuge in life is for washing clothes.

The problem was that there weren't many centrifuges in those days.

These centrifuges are rare and generally do not rotate very fast.

According to scientists' calculations, if a centrifuge is to be used to extract uranium, the ideal speed of the centrifuge must reach 20,000 revolutions per minute.

What is this concept?

To put it simply, this centrifugal force must rotate more than 333 rpm every second, while the high-end washing machines of later generations only have 1200 rpm.

Computer disks are more advanced, only 7200 rpm.

However, the speed of high-speed medical centrifuges in later generations only reached 15,000 rpm, and only expensive ultra-high-speed centrifuges could reach more than 80,000 rpm.

But think about it, how many years and how many technological differences are there?

Therefore, the only problem facing this group of scientists now is how to increase the speed of the centrifuge to more than 20,000 rpm.

From a purely technological perspective, it is too late to invest more in developing high-speed centrifuges.

Therefore, this group of scientists came up with the stupidest but most effective method at present, which is to work hard to create a miracle.

To put it bluntly, a centrifuge is actually an electric motor that drives an object to rotate at high speed. So now the problem is simple.

A normal electric motor cannot increase the speed to the desired speed, so is it possible to use a large gear with a small gear, and use the speed difference between the gears to increase the speed of the centrifuge?

One electric motor is not enough and does not have such a high speed. How about using a compensator to make multiple electric motors work at the same time?

Use the simplest and stupidest way to achieve your goals.

After discussion, this plan was unanimously approved by all the scientists, so a plan signed by the names of the entire base's scientists was handed over to Lin Yi.

After Lin Yi saw this plan, he was stunned.

It's so simple, so crude, it's comparable to the later furry bears.

Lin Yi still remembers a joke from later generations, that is, Milician developed a high-speed reconnaissance bomber aircraft, code-named XB-70 Valkyrie. The maximum speed of this aircraft reached a terrifying Mach 2.5.

This seriously threatened Mao Xiong, so Mao Xiong also planned to build a fighter specifically for the Valkyrie.

But at that time, Mao Xiong's technological level was not as good as that of Millikin, especially in terms of materials and engines.

Ever since, the furry bears thought of the simplest way, which is to work hard to create a miracle.

Isn't it just that the engine thrust is not enough? Then just make a direct modification and change the original engine to super power, without considering the engine life or other things.

As a result, this kind of engine was quickly manufactured.

But after solving the problem of engine thrust, the group of scientists discovered that under such a large thrust, the friction between the fuselage and the air would generate a large amount of heat. The temperature of some parts of the fuselage's surface may even reach 300 degrees.

Ordinary aircraft materials could not withstand such high temperatures, so Mao Xiong's experts changed the aircraft's fuselage to stainless steel.

There is simply no way to solve the problem, so just kill the "person" who raised the problem.

But it was such a monster-like aircraft that flew at a terrifying speed of Mach 2.83.

This is simply a classic representation of Dali bricks.

But now, it is Daxia who is flying bricks...

Since I can't build a high-speed centrifuge that meets the requirements, I will just fly bricks vigorously, use multiple motors or directly enlarge the motors and use differential speed to increase the speed.

When Lin Yi saw this plan, he was surprised at first glance and admired at second glance.

Lin Yi had to admire that these talents trained by the empire could think of such a method.

Lin Yi then approved the plan and let them go ahead with it.

After getting Lin Yi's approval, this group of scientists was ecstatic, and they immediately started manufacturing.

In just one month, this group of scientists created a prototype, and then started preparing for the first purification test non-stop.

But this time, Lin Yi did not arrive at the scene, but stayed away from the base.

Are you kidding? This is uranium. If you expose it to just a little bit, your life will be over.

Lin Yi felt that he still had a lot to do, so he didn't want to put himself in danger.

Of course, this was also strictly required by those scientists, because no one knew at that time how dangerous this uranium-235 could be.

Lin Yi just went with the flow and stayed in the building outside the base to wait for news.
